Adding custom product fields to woocommerce without using plugins

If you are selling product like printed T-Shirts, Cakes etc.., through online, you need to get some additional information from customer while placing their order.

Like name to be printed on the t-shirt (or) message to be written on the cakes.

In woocommerce it can be done via order meta. In this article you will find how to achieve this without using any plugins.

I have developed a wordpress plugin for this purpose, checkout WC Fields Factory, a wordpress plugin for creating woocommerce custom product fields.!

Let’s assume you are selling printed t-shirts, we will add name on t-shirt text box in your product page.

Place the following code in your functions.php

/**
 * The following hook will add a input field right before "add to cart button"
 * will be used for getting Name on t-shirt 
 */
function add_name_on_tshirt_field() {
    echo '<table class="variations" cellspacing="0">
	      <tbody>
	          <tr>
		      <td class="label"><label for="color">Name On T-Shirt</label></td>
		      <td class="value">
		          <input type="text" name="name-on-tshirt" value="" />                      
		      </td>
		  </tr>	        					
	      </tbody>
	  </table>';
}
add_action( 'woocommerce_before_add_to_cart_button', 'add_name_on_tshirt_field' );

The above code will insert a text field in your woocommerce product page, so that customer can enter their name that has to be printed on the ordered t-shirt.

Place the following code in your functions.php

function tshirt_name_validation() {	
	if ( empty( $_REQUEST['name-on-tshirt'] ) ) {
		wc_add_notice( __( 'Please enter a Name for Printing&hellip;', 'woocommerce' ), 'error' );
		return false;
	}
	return true;
}
add_action( 'woocommerce_add_to_cart_validation', 'tshirt_name_validation', 10, 3 );

The above code will do the validation for name-on-tshirt field.

Place the following code in your functions.php

function save_name_on_tshirt_field( $cart_item_data, $product_id ) {
	if( isset( $_REQUEST['name-on-tshirt'] ) ) {
		$cart_item_data[ 'name_on_tshirt' ] = $_REQUEST['name-on-tshirt'];
		/* below statement make sure every add to cart action as unique line item */
		$cart_item_data['unique_key'] = md5( microtime().rand() );
	}
	return $cart_item_data;
}
add_action( 'woocommerce_add_cart_item_data', 'save_name_on_tshirt_field', 10, 2 );

The above code will store the custom fields ( for the product that is being added to cart ) into cart item data ( each cart item has their own data )

Place the following code in your functions.php

function render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {
    $custom_items = array();
	/* Woo 2.4.2 updates */
	if( !empty( $cart_data ) ) {
		$custom_items = $cart_data;
    }
	if( isset( $cart_item['name_on_tshirt'] ) ) {
        $custom_items[] = array( "name" => 'Name On T-Shirt', "value" => $cart_item['name_on_tshirt'] );
    }
    return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

The above code will render the custom data in your cart and checkout page.

Place the following code in your functions.php

function tshirt_order_meta_handler( $item_id, $values, $cart_item_key ) {
	if( isset( $values['name_on_tshirt'] ) ) {
		wc_add_order_item_meta( $item_id, "name_on_tshirt", $values['name_on_tshirt'] );
	}
}
add_action( 'woocommerce_add_order_item_meta', 'tshirt_order_meta_handler', 1, 3 );

This is a piece of code that will add your custom field with order meta.

Custom Fields for Particular Product Category ( or for a particular product )
If you wanted to add custom fields for a particular product category, change your add_name_on_tshirt_field() as

function add_name_on_tshirt_field() {
 if( has_term( array('term1', 'term2', 'term3'), 'product_cat' ) ) {
    echo '<table class="variations" cellspacing="0">
	      <tbody>
	          <tr>
		      <td class="label"><label for="color">Name On T-Shirt</label></td>
		      <td class="value">
		          <input type="text" name="name-on-tshirt" value="" />                      
		      </td>
		  </tr>	        					
	      </tbody>
	  </table>';
   }
}

if you wanted for a particular product, change the if condition as

if( get_the_title() == "Your Product Title" ) {
	echo 'Your custom fields';
}

note: you should also update your tshirt_name_validation() to validate only for the category or for the product alone. eg.

function tshirt_name_validation( $flaq, $product_id, $quantity, $variation_id, $variations ) {	
    if( get_the_title( $product_id ) == "Your Product Title" ) {
        if ( empty( $_REQUEST['name-on-tshirt'] ) ) {
		wc_add_notice( __( 'Please enter a Name for Printing…', 'woocommerce' ), 'error' );
		return false;
	}
    }	
    return true;
}

    Hi

    This is great post and the plugin works great. Would it be possible to add the users input, in your example “Name”, directly on the shirt so the user has a visual of what they will actually see?

    Hi Saravana!

    Great Article I’m trying to do some stuff like this and search for it from many days and last I found your article which is amazing and really helpful. kindly help me with some of my issues first one I want to show this custom filed on my shop page or the product page and I want to show some user metadata in the order page can you help me with this.

    Thanks

  6. Tony September 4, 2017

    So I’ve got this entire set-up working – it’s pretty lengthy… I’m using the extra fields for parents to register their children for a football program.

    Before adding the custom fields I actually added an option to the Products in the back-end that essentially flags a product as a “Player Registration”.

    I have set it up so that the extra fields ONLY appear on registration product, which is perfect. My issue is that the validation for my custom fields runs on every product’s page and not just on my registration products with the extra fields. This results in those products not being able to be purchased because it’s trying to validate fields that don’t exist.

    Any idea why the following would work to display the fields, but doesn’t work to isolate the validation to ONLY the registration products?

    “`if( get_post_meta( get_the_ID(), ‘_player_registration’, true ) == ‘yes’ ) {

    }“`

    That works for the registration fields, but it doesn’t work for the validation process.

    1. Tony September 4, 2017

      I actually managed to sort this out at a deeper level… …when running the validation I added an isset requirement to go with the empty, so this now only executes if the fields exist and no longer effects different products:

      if ( empty( $_REQUEST['player_firstname'] ) && isset( $_REQUEST['player_firstname'] ) ) {
      wc_add_notice( __( 'Please provide the legal firstname for the player you intend to register.', 'woocommerce' ), 'error' );
      return false;
      }

    “July”, “August”, “September”, “October”, “November”, “December”];
    today = monthNames[d.getMonth()] + ‘ ‘ + d.getDate() + ‘ ‘ + d.getFullYear();

    $(‘#to’).attr(‘disabled’, ‘disabled’);
    $(‘#from’).datepicker({
    defaultDate: “+3d”,
    minDate: 3,

    dateFormat: ‘dd M yy’,
    showOtherMonths: true,
    changeMonth: true,
    selectOtherMonths: true,
    required: true,
    showOn: “focus”,
    numberOfMonths: 1,
    });

    this is the script how can i pass this with ur code

  10. Gwylohm July 28, 2017

    Hi,
    Firstly, I would like to thank you for this fabulous tutorial.
    However, I have a question : How do I integrate fields according to variations?
    For example, the red t-shirt will have 1 field, the blue variation will have 2.
    Is it similar to : “if( get_the_title() == “Your Product Title” )”, but with the ID of the variation ?
    Thanks a lot for your response.

    I used WC Fields Factory but I have some specific fields in Brazil, like the CPF, an identification code, in which I need to include validation before making the purchase.

    1. Saravana Kumar K March 15, 2017

      You can use woocommerce_add_to_cart_validation filter for that purpose

      function validate_custom_fields( $passed, $pid = null ) {
      	if( isset( $pid ) ) {
      		$is_passed = $passed;	
      		
      		/* This will retrieve all the custom fields post */
      		$all_fields = apply_filters( 'wcff/load/all_fields', $pid, 'wccpf' );
      		
      		/* Iterate through custom fields post */
      		foreach ( $all_fields as $title => $fields ) {
      			/* Iterate through custom fields */
      			foreach ( $fields as $field ) {
      				if( $_REQUEST[ $field["name"] ] ) {
      					/* See if it is your field and do your validation */
      					
      				}
      			}
      		}		
      	}
      	/* return true for success
      	 * return false to abort add to cart action */
      	return $is_passed;
      }
      add_filter( 'woocommerce_add_to_cart_validation', 'validate_custom_fields', 99, 2 );

    working perefect but how can i use this

    for example:

    how can i add my custom text
    name-on-tshirt as variable
    $name-on-tshirt=”mytext”;
    WC()->cart->add_to_cart($product_id,$quantity,$name-on-tshirt );

    this is my update.php

    // var_dump( $cart_item );

      i want that all products that added using my plugin will have custom text to each product with my generated upload id for example “35235252”

      i creating upload files plugin and the only thing that i can;’t figure out is how after files uploaded to pass the upload id to eeach file in cart
      so later i can use it and know what files to what client and what products

      i only need to pass temp order id that al ready created.
      using “name_on_tshir”

      as id meta
      for exampole name_on_tshirt=”543535353″
      and each upload new id is generated
      so if client uploading new files and each files is assoited with the upload id generated from this upload.

    Hello Saravana,
    great plugin and great support! I am trying to modify this script so it can use dropdown select options. But it only renders first option on page. Do you know what I am doing wrong?

    Here is modified code:
    function add_name_on_tshirt_field() {
    echo ‘

    Frame Color

    White
    Black

    ‘;
    }
    add_action( ‘woocommerce_before_add_to_cart_button’, ‘add_name_on_tshirt_field’ );

    Hi Saravana,

    thanks for this great tips you have provided. I have a small question: if you use this code
    wc_add_order_item_meta( $item_id, "name_on_tshirt", $values['name_on_tshirt'] ); to store the value, then label for this field is being rendered in Admin area as “name_on_tshirt”. Is there a way to override this and provide your own label so in the database it stores the key but in the admin it shows your own value? Thanks in advance for your help!

      Hi, it is saved with the customers Cart object, to be precisely, all custom fields are saved as Cart Line Item, which you can easily retrieve by Iterating through Cart Line object, do some thing like this.

      if( count( WC()->cart->get_cart() ) > 0 ) {
      	foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
                      // All key created by the WC Fields Factory must be prefixed with "wccpf_"
      		if( isset( $cart_item[ "wccpf_your_custom_field_name" ] ) ) {
      			echo $cart_item[ "wccpf_your_custom_field_name" ];

    One more question: How show this value on cart for eatch product?

    Really tks for explanation!

  33. Felipe August 29, 2016

    I would first like to thank you for the beautiful initiative to help us develop an increasingly perfect e- commerce.

    My question is – I need to deploy a field for the Admin , for that would have to modify the first part of the code in this tutorial, where a field is created on user screen for a field on admin screen. But I’m not getting through my code to link with the rest of the codes of this tutorial.

    Below follow my code:

    function woo_add_custom_general_fields() {
    
      global $woocommerce, $post;
      
      echo '';
      
      woocommerce_wp_text_input( 
    	array( 
    		'id'                => 'dias_fabricacao', 
    		'label'             => __( 'Days', 'woocommerce' ), 
    		'placeholder'       => '', 
    		'description'       => __( Enter here the days for manufacturing', 'woocommerce' ),
    		'type'              => 'number', 
    		'custom_attributes' =>

    Could you help me?

    Tks!

      Hi here is the complete code for Custom Admin Fields

      function add_custom_admin_field() {
      
      	woocommerce_wp_text_input( 
      	    array( 
      		'id'                => 'dias_fabricacao', 
      		'label'             => __( 'Days', 'woocommerce' ), 
      		'placeholder'       => '', 
      		'description'       => __( Enter here the days for manufacturing', 'woocommerce' ),
      		'type'              => 'number', 
      		'custom_attributes' => 
      		    array(
      		        'step'  => 'any',
      		        'min'   => '1'
      		    ) 
      	    )
      	);
      
      }
      add_action( 'woocommerce_product_options_general_product_data', 'add_custom_admin_field' );
      

      The above snippet add a custom text field under General Product Tab ( I assume you wanted to create custom fields for woocommerce admin product screen )

      function save_custom_admin_fields( $post_id ) {	
      	
      	if( !empty( $_POST['dias_fabricacao'] ) ) {
      		update_post_meta( $post_id, 'dias_fabricacao', esc_attr( $_POST['dias_fabricacao'] ) );
      	}
      
      }
      add_action( 'woocommerce_process_product_meta', 'save_custom_admin_fields' );
      

      Above snippet will save the custom fields whenever user clicked Update button

      and if you want to access this field’s value else where, you can use the famous get_post_meta() function.

    this is awesome!!! Thank You!!

    Hello Saravana!

    I want to use these codes, but change them a bit so they suit my needs better. However I’m nothing but a novice and I don’t know how to correctly do it. Maybe you could help me with that?

    I need to:
    • Either have the text-fields in the Cart page (next to each product) instead of the Product page
    • Or keep the text-field on the Product page as it is, save it, then show it on the Cart page BUT give the option to Edit the content of the text-field.

    In both cases, I need the comments of the text-fields to show at the order and invoice…
    Any ideas? I’m really looking forward to your answer, I was looking for a way to do this for days!

  36. Thomas Schmidt June 15, 2016

    Hi Saravana,

    Did you find a solution for adding the same product to the cart multiple times with different custom meta and the possibility of editing the product and the custom meta?
    Currently when I edit a product from my cart, the custom meta is displayed from the last product which was added to the cart.

    1. Saravana Kumar K June 15, 2016

      Hi Thomas, sorry I totally forgot, any here is the idea how you can achieve that

      you will have to edit your your-theme/woocommerce/cart.php ( especially product-thumbnail TD and product-name TD )

      <td class="product-thumbnail">
      	<?php
      		$thumbnail = apply_filters( 'woocommerce_cart_item_thumbnail', $_product->get_image(), $cart_item, $cart_item_key );
      
      	if ( ! $_product->is_visible() ) {
      		echo $thumbnail;
      	} else {
      		if( isset( $cart_item["name_on_tshirt"] ) ) {
      			printf( '<a href="%s">%s</a>', esc_url( $_product->get_permalink( $cart_item ) ."?name_on_tshirt=" .$cart_item["name_on_tshirt"] ), $thumbnail );
      		} else {
      			printf( '<a href="%s">%s</a>', esc_url( $_product->get_permalink( $cart_item ) ), $thumbnail );
      		}
      	}
      	?>
      </td>
      
      <td class="product-name" data-title="<?php _e( 'Product', 'woocommerce' ); ?>">
      	<?php
      		if ( ! $_product->is_visible() ) {
      			echo apply_filters( 'woocommerce_cart_item_name', $_product->get_title(), $cart_item, $cart_item_key ) . ' ';
      		} else {
      			if( isset( $cart_item["name_on_tshirt"] ) ) {
      				echo apply_filters( 'woocommerce_cart_item_name', sprintf( '<a href="%s">%s</a>', esc_url( $_product->get_permalink( $cart_item ) ."?name_on_tshirt=" .$cart_item["name_on_tshirt"] ), $_product->get_title() ), $cart_item, $cart_item_key );
      			} else {
      				echo apply_filters( 'woocommerce_cart_item_name', sprintf( '<a href="%s">%s</a>', esc_url( $_product->get_permalink( $cart_item ) ), $_product->get_title() ), $cart_item, $cart_item_key );
      			}								
      		}
      
      		// Meta data
      		echo WC()->cart->get_item_data( $cart_item );
      
              	// Backorder notification
      		if ( $_product->backorders_require_notification() && $_product->is_on_backorder( $cart_item['quantity'] ) ) {
      			echo '<p class="backorder_notification">' . esc_html__( 'Available on backorder', 'woocommerce' ) . '</p>';
      		}
      	?>
      </td>
      

      and then update your add_name_on_tshirt_field function like this

      function add_name_on_tshirt_field() {
      	global $post;
      	$name_on_tshirt = "";	 
      	
      	if( isset( $_GET["name_on_tshirt"] ) ) {	
      		$name_on_tshirt = $_GET["name_on_tshirt"];
      	}
      	 
      	echo '<table class="variations" cellspacing="0">
                <tbody>
                    <tr>
                    <td class="label"><label for="color">Name On T-Shirt</label></td>
                    <td class="value">
                        <input type="text" name="name-on-tshirt" value="'. esc_attr( $name_on_tshirt ) .'" />
                    </td>
                </tr>
                </tbody>
            </table>';
      }
      add_action( 'woocommerce_before_add_to_cart_button', 'add_name_on_tshirt_field' );
      

      So basically what I did is, I added them as query variable at cart.php and in add_name_on_tshirt_field I am check for the corresponding query var, if I find one then we can fill that fields value attribute.

  37. Maya June 12, 2016

    Yes exactly that, this link is a screenshot of what my admin order page looks like: http://findcreative.london/current.png and this link is a screenshot of what I want it to look like: http://findcreative.london/ideal.png I think I need to edit the wc_add_order_item_meta section to something else but I’m not sure what, thanks.

  38. Maya June 12, 2016

    How do I display this as a custom field value on the order admin panel? Currently it only shows as a field underneath the phone number, I would also like it to show as a custom field on the order page too.

    Thanks

    1. Saravana Kumar K June 12, 2016

      I don’t understand your requirement, currently the custom fields value will be stored as Cart Item Data while your add to cart action and then once you placed the order, it will be stored as Order Item Meta which will be carried over to Order Email, Order Thank You page and Order Back end screen as well ( it will be displayed under the product title of each line item ).

      You want to add custom fields on Order back end screen, where admin user would able to update.?
      something like that.?

  39. Victor Flores June 8, 2016

    Hi Saravana!

    I was just wondering if there is a way to collect the meta order information and display it in the cart when cloning is activated.

    Thank you in advance!

    1. Saravana Kumar K June 8, 2016

      Hi it’s already possible with WC Fields Factory, It should work straight away, I don’t know what difficulties you are facing. If it is anything, could you be more specific so that I can try to point you in the right direction.

  40. Thomas Schmidt June 7, 2016

    I make use of 4 custom fields:
    – 1x custom price submission
    – 3x custom texts

  41. Thomas Schmidt June 6, 2016

    Hi Saravana,

    Thanks for the reply, but this would work if you only add one product to the cart.
    When you add more of the same product there isn’t any distinction between the two, because you are using the product ID which is the same for both products.
    Is there a way to achieve the same result using another type of identifier (like the ‘cart_item_key’)?

    Cheers,

    Thomas

    1. Saravana Kumar K June 7, 2016

      Hi, got your point, but I don’t see any solution there, even if you use cart_item_key, because you are in product page and all you have is product_id and you have no way to know what cart_item_key should be used against this product page ( especially if you have more than one line item of the same product ).

      I think I have an idea, how many custom fields you have in your product page.?

  42. Sarah May 31, 2016

    Hi, how do I add the field to the checkout page?

    1. Saravana Kumar K June 7, 2016

      Hi, it’s depends on what you are going to do with that custom field. In checkout page where exactly you wanted to add that fields.? you may go through this article where you can find the idea about custom fields on checkout page.

  43. Anna May 26, 2016

    Hello,
    I’m using the plugin linked at the beginning of the article, I was wondering if it would be possible to show the custom field after you’ve selected the option in a variable product.

    For example if you have two attributes, one is no message and the other one is message inside, when you select message inside then showing the custom field.

    Thanks!

    1. Saravana Kumar K May 27, 2016

      Yes you can.

      Step 1 : You will have to create two “WC Product Field Group”. on the front end product page each Field Group will be wrapped with divs contains css classes like this wccpf-fields-group-1, wccpf-fields-group-2 ( we are going to use these css class to do the toggling )

      Step 2 : paste the following snippet your functions.php

      function variable_reload_field() { ?>	
      	
      <script type="text/javascript">
      
      (function($){
      	// Update "#pa_size" id with your attribute select box ID
      	$(document).on( "change", "#pa_size", function(){
      		$('[class^="wccpf-fields-group-"]').hide();
      		if( $(this).val() == "medium" ) {
      			$(".wccpf-fields-group-2").show();
      		} else {
      			$(".wccpf-fields-group-1").show();
      		}
      	});
      })(jQuery);
      
      </script>
      	
      	<?php 
      }
      add_action( 'woocommerce_after_add_to_cart_form', 'variable_reload_field' );
      
  44. Thomas Schmidt May 24, 2016

    Great explanation, it helped me a lot!
    Is it possible to automatically fill in the ‘Name on shirt’ field with the customers value, when the ‘edit product’ url is pressed in cart?

    1. Saravana Kumar K May 27, 2016

      Hi yes that is possible here is a snippet

      function add_name_on_tshirt_field() {	
      	global $post;
      	$name_on_tshirt = "";
      	
      	foreach ( WC()->cart->cart_contents as $key => $value ) {
      		if( $value["product_id"] == $post->ID && isset( $value["name_on_tshirt"] ) ) {
      			$name_on_tshirt = $value["name_on_tshirt"];
      		}
      	}
      	
      	echo '<table class="variations" cellspacing="0">
                <tbody>
                    <tr>
                    <td class="label"><label for="color">Name On T-Shirt</label></td>
                    <td class="value">
                        <input type="text" name="name-on-tshirt" value="'. esc_attr( $name_on_tshirt ) .'" />
                    </td>
                </tr>
                </tbody>
            </table>';
      }
      add_action( 'woocommerce_before_add_to_cart_button', 'add_name_on_tshirt_field' );

    1. Saravana Kumar K May 17, 2016

      Hi, first of all this article work only for adding custom fields on your product page ( not on cart, of course those custom fields values will be carried over to cart, checkout, order & email ).
      So you managed to add custom fields on cart page and not able to carry the value to checkout page. am I right.?

  47. Andreas April 21, 2016

    Sorry, please delete my previous post. Just found the answer in the tutorial. Your scrolling javascript function/animation makes it impossible to scroll the page and view info 🙂

    Thanks again.

  48. siva April 21, 2016

    very nice,

    how to display select box value in cart page?

    1. Saravana Kumar K April 25, 2016

      Hi, the same code should be work for select field as well. you will have to change the check box into select field in the add_gift_wrap_field handler.

  49. Phil March 23, 2016

    I’m using another plugin (dvin-wcql) that turns woocommerce’s normal cart functionality into a quote request form.

    So none of the above works, because it saves all the data into the cart item variables.

    In the code of the ‘quote request’ plugin, in the place where the order is created, I want to fetch the custom value from the session and add it to the order. However, I don’t understand the above well enough to know where the value is stored.

    Any help is much appreciated.

    1. Saravana Kumar K March 23, 2016

      Hi, I never used that plugin before, if it is possible sent the code, I will have a look at it.

  50. Jomar March 10, 2016

    I tried it and it works but I don’t know how to get that work in order item meta. Will it work using woocommerce hook (woocommer_add_order_item_meta)? I tried that before but don’t know how to display it in order item meta 🙂

  51. Jomar March 7, 2016

    Hi,

    Nice tutorial. How about having an array value in one item meta key… How to implement in order to display the item meta in cart and checkout page as well as order item meta.

    1. Saravana Kumar K March 8, 2016

      I mean, one of your cart item meta is having an Array as a value and you wanted to display it in Cart, Checkout and also add as Order Item Meta right.?

      If that is the case just convert your Array into a CSV and add as meta like this implode( ", ", $your_array );

  52. danielo January 21, 2016

    Hi,
    I have used the updated code and everything works fine BUT, the data is not stored in order meta. If I do it with the plugin it works.. but I want to add that information programatically; as that’s how I am adding the products.

    So, any lead on why it might not work? You probably need to update some of the WC functions?

    1. Saravana Kumar K January 21, 2016

      Hi, woocommerce_add_order_item_meta this is the action you will have to use. and there was a bug on my tshirt_order_meta_handler snippet, I have updated it now, please have a look.

    Hi Saravana,
    Thanks , but the last step is don’t wok on my side please give me a solution for order details.

    function tshirt_order_meta_handler( $item_id, $values, $cart_item_key ) {
    if( isset( $cart_item[‘name_on_tshirt’] ) ) {

    1. Saravana Kumar K November 23, 2015

      You got a bug on wc_add_order_item_meta statement, there is no $cart_item object in this handler, only $values. use the below snippet.

      function tshirt_order_meta_handler( $item_id, $values, $cart_item_key ) {
      if( isset( $values[‘name_on_tshirt’] ) ) {
      wc_add_order_item_meta( $item_id, “name_on_tshirt”, $values[‘name_on_tshirt’] );

    Second Line:: Product 1 [Demo 2]————————————————-price————-Total Price

    But i want to change thing like this ::

  64. Payman November 4, 2015

    Hi Saravana,

    I am using your custom field and it is working perfectly. However, I wanted to add another field to the current one and as soon as I go to Fields Factory > Write tab in admin it goes to 404 page. Do you know what is the problem?

  65. Jp October 26, 2015

    Hello Saravana.
    Thank you for your excellent article. Could you help me with this issue? When i fill in the textbox with the tshirt color and i click on ‘Add to cart’ button and the page reloads, the text field “Name on T-Shirt” remains empty. Is there a way to keep the textbox filled with the input?
    Thank you in advance.

    1. Saravana Kumar K September 10, 2015

      Hi, it’s been my long time pending work, hope I will finish this feature soon and release it. ( You can do it by yourself, you would needing some custom jQuery snippets & server side logic, it’s easy though ).

  68. Abi August 4, 2015

    Hello Saravana, excellent work, I have a issue, I’m using your plugin Fields Factory, but when a required field is validated shows messages error correctly but it add the product to cart anyways, I tried validation via snippet but shows the message and adds the product to cart too. What I have to do to avoid it adds to cart until the field is filled?. Thank you.

    1. Saravana Kumar K August 6, 2015

      Abi Thank You,

      Change add_action statement for validation to this add_action( 'woocommerce_add_to_cart_validation', 'tshirt_name_validation', 10, 3 );, number of parameter count might be the reason.

    Can I use after_woocommerce_pay for this?

    1. Saravana Kumar K July 23, 2015

      You can use either woocommerce_payment_complete or woocommerce_payment_complete_order_status_completed action, which will be triggered with $order_id as a parameter.

  71. Ajay July 20, 2015

    Hi Saravana,

    I tried using the code you provided (pasted it in the functions.php exactly as is) to try and get it working before customising it for my own needs. No errors show up when viewing the product page but when I click “Add to Cart” it doesn’t add the product to the cart, instead it just shows the loading gif which never stops.

    I thought maybe I had screwed something up and created an infinite loop somewhere; so I tried your plugin and it appears to be doing the same thing.

    Any ideas of what might be going wrong? I’d link you to a website but I’m working on a local server.

    1. Saravana Kumar K July 21, 2015

      Ajay,

      Neither WC Fields Factory nor that custom code in your functions.php won’t work with Ajax enabled Add to Cart method, you should disable your Ajax add to cart feature from woocommerce setting page. you can see that page in wp-admin->woocommerce->settings->products->Display.

      1. Ajay July 21, 2015

        Thanks for your reply Saravana, I disabled Ajax in woocommerce but the problem seems to persist. Nothing has changed, the ajax still runs and the infinite loop is still there. I’ve tried overriding with the following code but nothings changed :/


        function so_27023433_disable_checkout_script(){
        wp_dequeue_script( 'wc-checkout' );
        }
        add_action( 'wp_enqueue_scripts', 'so_27023433_disable_checkout_script' );

  72. Elvin Lee July 14, 2015

    Hi Saravana,

    This is a nice snippet which without plugin. May I know how to set apply only selected products? For example: input field A, B for A, B, C, D products; input field C, D for products E, F, G, H.

    Regards,
    Elvin

    1. Saravana Kumar K July 14, 2015

      Hi Lee, You can add those kinds of rules like this

      add_name_on_tshirt_field() {
          if( get_the_title() == "Product A" || get_the_title() == "Product B" ) {
             echo 'Your custom fields set A';
          } else if( get_the_title() == "Product C" || get_the_title() == "Product D" ) {
             echo 'Your custom fields set B';
          }
      }
      

      You can also use this plugin, which will make your life lot easier

  73. Naval Kishore Kandpal July 6, 2015

    Sir, I’ve installed your plugin and I’ve used the “date picker” field on the product page of my website. The date picker is showing but when I add the product into cart, the date I selected doesn’t appear in the Cart and Checkout page. Even it doesn’t show in the Admin.
    Please give me a solution ASAP.

    1. Saravana Kumar K July 6, 2015

      Hi,

      What theme you are using.?, the following two hooks are crucial for this plugin woocommerce_add_cart_item_data and woocommerce_get_item_data, make sure those hooks are available in your theme.

      1. Naval Kishore Kandpal July 7, 2015

        Sir, I’m using a woo commerce theme already. Where do I find these two hooks? And if these hooks are not available then what should I do? Suggest me. I’m waiting for your response.

      2. Naval Kishore Kandpal July 7, 2015

        Both of these hooks are available in my theme inside “plugins/woocommerce/includes/class-wc-cart.php” page.

        1. Saravana Kumar K July 7, 2015

          Kishore,

          Than the issue could be any where ( themes or server session setup … ), you need to debug your theme, unless I have access to your themes code, I can’t help you more.!

      3. Naval Kishore Kandpal July 9, 2015

        Saravana Sir,
        Finally I’ve done it. Thanks a lot. I created a custom field by using the action hooks you’ve mentioned in this Blog. One thing I want now is that for example if someone orders a product, we can block the calendar field (which is my custom field), so the pick up date can only be visible after 24 hours of ordering.
        Please give me a solution.

    How I can unset the custom cart item from session on deleting the item from cart?

    1. Saravana Kumar K June 25, 2015

      You can use woocommerce_before_cart_item_quantity_zero hook for this purpose, some thing like this

      add_filter('woocommerce_before_cart_item_quantity_zero', 'on_cart_item_removed', 10, 1);
      function on_cart_item_removed( $cart_item_key ) {
      	if( $cart_item_key && WC()->session->__isset( $cart_item_key.'_name_on_tshirt' ) ) {
      		WC()->session->__unset( $cart_item_key.'_name_on_tshirt' );
      	}
      }
      
      1. Aba June 25, 2015

        Thanks Saravana,

        one more thing.. how can I update the image with a custom one. Like after product customization, my product image will change to a new one, how I can replace the original one with the new product image. Thanks in advance

  76. jose June 20, 2015

    I can only say thank you.

  77. Lila June 9, 2015

    Hello Saravana,
    thank you for teach us, I just want to show the last product added, with your plugin I’ve selected it just shows one product, but when I add another product, just shows the first product added and not current product added. Thank you for you help. What do you recommend me change?

    1. Saravana Kumar K June 9, 2015

      Lila,

      Not sure I am following you, last product added in what.? into cart.?, are you using WC Fields Factory or you are doing it manually.? could you explain it with more details.?

      1. Lila June 13, 2015

        I’m sorry, I was confused, I’m using WC Fields Factory, and I created a checkbox but the name field always created a name with “[ ]” in the end, like name=”my_field[]” and I’ve tried to overriding price with your snippet but it doesn’t work, I think is by “[ ]”, because when I did without plugin it actually works. Please, help me.

  78. Viv June 8, 2015

    Hi ,
    Saravana Kumar K thank you for post.
    the last step is don’t wok on my side please give me a solution for order details.

    function tshirt_order_meta_handler( $item_id, $values, $cart_item_key ) {
    if( WC()->session->__isset( $cart_item_key.'_name_on_tshirt' ) ) {
    wc_add_order_item_meta( $item_id, "name_on_tshirt", WC()->session->get( $cart_item_key.'_name_on_tshirt') );
    }
    }
    add_action( 'woocommerce_add_order_item_meta', 'tshirt_order_meta_handler', 1, 3 );

    1. Saravana Kumar K June 9, 2015

      Just make sure woocommerce_add_order_item_meta hook gets triggered.
      like this.

      function tshirt_order_meta_handler( $item_id, $values, $cart_item_key ) {
          error_log("Woocommerce Order Meta Hook Triggered");
      }
      add_action( 'woocommerce_add_order_item_meta', 'tshirt_order_meta_handler', 1, 3 );

    Thank you Saravana kumar..

  80. John May 25, 2015

    Hello Saravana,
    Thanks for the plugin it works great! I am using variable products though woo themes and have added the custom text box via your plugin. I want to hide/display the custom text box based on the variation selected for the product E.g. An attribute called ‘Number’ with variations ‘one’, ‘two’ & ‘three and only have the custom text field display when user selects variation ‘three’. I have 50 products I need to do this for. Is that possible? THANKS

  81. Mark April 29, 2015

    How can I donate to you for this fantastic article!

    1. Saravana Kumar K April 29, 2015

      Mark,
      Thank you, here is one of my wordpress plugin url, there you can donate.

  82. Zeeshan April 14, 2015

    Hello Saravana,
    Thank you for such an awesome plugin. I was finding a way to do this and then i came across your plugin.

    I just want to ask, can i make the fields editable on cart page ? like the quanity field is editable and can be updated, so can the custom fields could be done the same ? If yes can you guide me how can this be done ?
    Thank You 🙂

    1. Saravana Kumar K April 15, 2015

      Yes you can, by using woocommerce_cart_item_name

      function render_text_field_on_cart_item( $title = null, $cart_item = null, $cart_item_key = null ) {
      	if( $cart_item_key && is_cart() ) {
      		echo $title. '<dl class="">
      				 <dt class="">Your Text Field : </dt>
      				 <dd class=""><input type="text" name="'. $cart_item_key .'_your-cart-item-text-field" value="" /></dd>
      			  </dl>';
      	}else {
      		echo $title;
      	}
      }
      add_filter( 'woocommerce_cart_item_name', 'render_text_field_on_cart_item', 1, 3 );
      

      and save the those custom cart fields to session in order to use them later ( at checkout & order meta ) using woocommerce_before_calculate_totals hook

      function save_cart_item_text( $cart_object ) {	
      	foreach ( $cart_object->cart_contents as $key => $value ) {
      		WC()->session->set( $key."_cart_item_text", $_REQUEST[ $key."_your-cart-item-text-field" ] );		
      	}
      }
      add_action( 'woocommerce_before_calculate_totals', 'save_cart_item_text', 1, 1 );
      
  83. b1rken April 7, 2015

    Thanks, found this information very useful.

    Which filter/action should I use to dispay the inputed text in the header cart / cart “preview” on mouseover () ?

    1. Saravana Kumar K April 8, 2015

      Hi,

      I have updated the render_meta_on_cart_item(), just replace it, It should work now.

      function render_meta_on_cart_item( $title = null, $cart_item = null, $cart_item_key = null ) {
      	if( $cart_item_key && WC()->session->__isset( $cart_item_key.'_name_on_tshirt' ) ) {
      		echo $title. '<dl class="">
      				 <dt class="">Name On T-Shirt : </dt>
      				 <dd class=""><p>'. WC()->session->get( $cart_item_key.'_name_on_tshirt') .'</p></dd>			
      			  </dl>';
      	}else {
      		echo $title;
      	}
      }

    Hi Saravana,

    Many thanks for the code. Is it possible to put the custom field/text input on the Cart page?

    Cheers.

    1. Saravana Kumar K April 3, 2015

      Yes you can, by using woocommerce_cart_item_name

      function render_text_field_on_cart_item( $title = null, $cart_item = null, $cart_item_key = null ) {
      	if( $cart_item_key && is_cart() ) {
      		echo $title. '<dl class="">
      				 <dt class="">Your Text Field : </dt>
      				 <dd class=""><input type="text" name="'. $cart_item_key .'_your-cart-item-text-field" value="" /></dd>
      			  </dl>';
      	}else {
      		echo $title;
      	}
      }
      add_filter( 'woocommerce_cart_item_name', 'render_text_field_on_cart_item', 1, 3 );
      

      and save the those custom cart fields to session in order to use them later ( at checkout & order meta ) using woocommerce_before_calculate_totals hook

      	}
      }
      add_action( 'woocommerce_before_calculate_totals', 'save_cart_item_text', 1, 1 );
      
      1. Mcap666 April 3, 2015

        Thanks very much Saravana! That’s great and is working well. Sorry to ask for more, but can you let me know the code to render it on the checkout & order meta please? I can’t seem to get that working…

    1. Saravana Kumar K April 3, 2015

      Yes you can, at woocommerce_before_add_to_cart_button hook echo your file input tag ( like any other fields shown in the add_name_on_tshirt_field() function ) and add a call back function for woocommerce_add_to_cart hook and do your file uploading task there ( there are plenty of tutorials available for that like this one )

    hi, sorry for bothering you again,

    add_filter( 'woocommerce_checkout_cart_item_quantity', 'render_meta_on_checkout_order_review_item', 1, 3 );
    

    Do you have any idea?

    kind regards

    1. Saravana Kumar K March 25, 2015

      Looks fine except this WC()->cart->session on render_meta_on_cart_item(), It should be WC()->session->get, also you have many custom fields, which might make it hard to maintain your functions.php You can try WC Fields Factory to create and maintain custom fields and you would only need woocommerce_before_calculate_totals hook to alter the price.

  87. amit March 25, 2015

    hi, how can I make this field display only in a specific product category ? and you have also mentioned how to add custom fields for a particular product category but after doing this there is a blank label appear ( that is “Name On T-Shirt : ” ) i also want to hide this label from all other sections like from session, order, cart page and from back-end orders also. how can i do this ?

    1. Saravana Kumar K March 25, 2015

      Amit thanks for pointing out, I have updated the article. I have also developed a wordpress plugin for the exact purpose WC Fields Factory

      1. amit March 25, 2015

        thanks for the plugin its amazing . but i have one problem actually i have already did all the functionality according to your post in my function.php file. please have a look my site : , here i want grip-tape option: (apply grip tape for me or i’ ll apply it for myself). i have finished all the things and i want the same design as in my site so i only want to hide this grip-tape option: label from all other sections like from session, order, cart page and from back-end orders for any other category products. how can i do this ? i have removed it from product detail page now i only want to remove it from rest of the pages when user add to cart any different category products.

          1. Saravana Kumar K March 25, 2015

            Hi Amit, I have already updated the following snippets save_name_on_tshirt_field(), render_meta_on_cart_item(), render_meta_on_checkout_order_review_item(), tshirt_order_meta_handler() with additional condition. just update your snippets again, you will be fine.

    Sorry man, but i have a last question and i dont find the way to make it work, it is possible to change the price of the item depending on the custom field? For example: i have a to calculate a new price and show in the checkout for the item if the lenght of the text in the name-on-tshirt field is bigger then 20 characters, there is any way to do that?

    1. Saravana Kumar K March 13, 2015

      Yes it is possible, using woocommerce_before_calculate_totals hook you can dynamically alter the price, I have an article for the exact purpose.

      You want the custom input field for the entire order ( ex.. order note ) or for each order line item.?

  98. Jenny March 10, 2015

    Hello Saravana,

    Thanks for the great tutorial! I’m trying to use this feature on product listing page (content-product.php). For some reason the input field is not showing on the product listing page.

    The input is showing on the product detail page, but I’m not able to pass the validation after I input content and submit.

    Any ideas what is happening and how to fix?

    Thanks!
    Jenny

    1. Saravana Kumar K March 10, 2015

      Hi Jenny,

      This article has been written for adding custom fields only for product details page. I am planning to write another article for adding custom fields to the product archive page ( with Ajax support ).

      regarding the validation you might have to look into 'woocommerce_add_to_cart_validation' hook that’s where the validation is happening. here it would be tshirt_name_validation()

      1. Jenny March 11, 2015

        Yes, please. I look forward to see your article on product archive page. Do you have a timeframe for that?

        Thanks so much!

      Hi,

      Add the following snippet into add_name_on_tshirt_field() hook

      if( get_the_title() == "Your Product Title" ) {
      	echo 'Your custom fields';
      }
      

      for categories

      if( has_term( array('term1', 'term2', 'term3'), 'product_cat' ) ) {
      	echo 'Your custom fields';
      }

        Thanks for your answer, it’s exactly what i needed but i got an other problem.
        i’ve used the snippet for categories and create a categorie “customisable”.

        For customisable product there is no problem,
        but when i try to add a non customisable product to cart i got the error message :
        “Please enter a Name for Printing…”

        i tried several way to make it work but did not find the solution
        any idea of how to succed ? ^^

        thx again

          Hi, you need add the following condition in tshirt_name_validation()

          function tshirt_name_validation( $flaq, $product_id, $quantity, $variation_id, $variations ) {	
              if( get_the_title( $product_id ) == "Your Product Title" ) {
                  if ( empty( $_REQUEST['name-on-tshirt'] ) ) {
          		wc_add_notice( __( 'Please enter a Name for Printing…', 'woocommerce' ), 'error' );
          		return false;
          	}
              }	
              return true;
          }
          add_action( 'woocommerce_add_to_cart_validation', 'tshirt_name_validation', 1, 5 );

    Hi!

    What I could see, the field don´t show up anywhere in the order in WooC, or in the order email. How could I fix this?

    1. Saravana Kumar K March 4, 2015

      Hi Petter,

      The method won’t work if you add your product to cart using Ajax ( I haven’t tested it ). I am planning to update this article to work with Ajax too.

  103. weilin February 26, 2015

    Hello, thank you very much for your methodology, I want to add the commodity page now, in the virtual and download options next to add an option to control the text box to display or hide, because customers custom information does not support certain commodities, so can achieve very much looking forward to your reply?

  104. Rajiv Sharma February 25, 2015

    Great work…would follow your codes and learn from you..

    Thanks

  105. Mark February 18, 2015

    Thank you for this post, if I may ask does this also work on add to cart using ajax.?

    Thank you!
    Regards,
    Mark

    1. Saravana Kumar K March 4, 2015

      Hi sorry for the delayed response, I will update the article soon.

  106. james February 12, 2015

    Hello This is Great thank you quick question
    Is there a way in which I can have this only showing on certain products?
    Thank you so much in advance 🙂
    James

  107. Aleksandr Levashov February 10, 2015

    This code will group cart items with same custom data:

    function my_woocommerce_add_cart_item_data($cart_item_data) {
    	$cart_item_data['custom_data'] = $_REQUEST['custom_data'];
    	return $cart_item_data;
    }
    add_filter('woocommerce_add_cart_item_data', 'my_woocommerce_add_cart_item_data');

    Hi,

    I’m back 🙂 Thanks once again for all your help at the start of the year. It enabled me to launch my site and I am now actively receiving orders!

    Can I ask if it’s possible to have different custom fields show on different product pages? If so can you please assist me in how I would do this? What I’m achieve is this…

    On my product page I have birthday, anniversary and valentines day. Each product has two custom fields – Name & Date. The valentines day product doesn’t need a date field as it always falls on the same day every year. Therefore for this product I’d like to remove the Date field.

    Thanks in advance
    Kind regards
    Paul

    1. Saravana Kumar K February 6, 2015

      Hi Paul, that’s easy you can do some thing like this

      function add_name_on_tshirt_field() {
         if( get_the_title() == "your product title" ) {
            // your special custom fields
         } else {
            // your normal custom fields
         }
      }
      
      1. Paul Moreton February 7, 2015

        Thanks once again for your help, I appreciate it a lot 🙂

        Where you say “your product title” would this be the individual product page UR?

        Cheers
        Paul

        1. Saravana Kumar K February 7, 2015

          Yes, the product title, to which you wanted a different set of custom fields.

  109. fishing lovers January 30, 2015

    You ave made some really good points there. I looked on the net for more info about the issue and found most individuals will go along with your views on this site.

  110. Tian January 15, 2015

    If a particular product is sold out, anyway we can hide the fields from showing?

    1. Saravana Kumar K January 15, 2015

      Yes you can, do some thing like this,
      place the below code in add_name_on_tshirt_field()

      global $post;
      if( get_post_meta( $post->ID, '_stock_status',true ) == 'outofstock' ) {
      	//do your stuf here
      } 
      
      1. tian January 15, 2015

        This will only work if the product has no variation, but products that has variations, i am unable to get the ID as it keeps retrieving the main product ID. Please advise. Thanks!

  111. Jamez January 11, 2015

    Hi Saravana Kumar.
    This sounds like a perect solution to a problem I simply couldn’t solve nor have the skills to be able to!
    I can’t find the complete final solution code ? would you mind mailing it to me please?.

    I hope to modify the code for a differnet purpose, i.e club membership, variables = New member, Existing member, and if non member a fee applies, if existing member, just state Existing. I am hoping to add variations via drop box or maybe radio buttons and pass this on to cart as with T shirt example
    Thank you very much in advance

    1. Saravana Kumar K January 12, 2015

      Hi Jamez,

      Here is the complete source

  112. Johan van Zijl January 11, 2015

    Thank you, was just the item I was looking for. Can you explain how to get this extra field in the email which is send to the seller and customer?

    1. Johan van Zijl January 11, 2015

      Sorry was a typing error it is there now!

  113. tian January 4, 2015

    Hi Saravana Kumar,

    Firstly i like to thank you for this marvelous tutorial. It helped me use this function, without spending money on paid plugins. I also managed to display the fields only on specific variation products that i want it to show.

    I would like to know if field validation is possible? Eg: make it a required field before a user is able to add to cart. Please advise thank you 🙂

    1. Saravana Kumar K January 4, 2015

      Hi Tian,

      I have updated the article, validation functionality has been added tshirt_name_validation().

      1. Tian January 5, 2015

        Thank you Saravana Kumar! Nice 🙂

      2. zee January 30, 2015

        Validation function is not working for multiple custom fields. It keeps showing you the error, even though the field is not empty. Can you please help.

        This is my code:

        function tshirt_name_validation() {
        	if ( empty( $_REQUEST['name-on-tshirt'] ) ) {
        		wc_add_notice( __( 'Please enter a Name for Printing…', 'woocommerce' ), 'error' );
        		return false;
        	}
        	return true;
        }
        add_action( 'woocommerce_add_to_cart_validation', 'tshirt_name_validation', 1, 5 );
        
        1. Saravana Kumar K January 30, 2015

          Hi,

          The validation code should work for multiple fields too. you just have to add appropriate if condition like

          if ( empty( $_REQUEST[‘field-one’] ) ) {
             wc_add_notice( __( ‘Please enter a Fields One’, ‘woocommerce’ ), ‘error’ );
             return false;
          }
          if ( empty( $_REQUEST[‘field-two’] ) ) {
             wc_add_notice( __( ‘Please enter a Fields Two’, ‘woocommerce’ ), ‘error’ );
             return false;
          }
          
          1. zee January 30, 2015

            Thanks for the quick reply, but it’s not work. I know its me, not really bright in coding 😉 It gives you the first error message, though the fields are not empty.

            Here’s my code, can you please check what I am doing worng:

            function multiple_field_validation() {
            	if ( empty( $_REQUEST['field-one'] ) ) {
            		wc_add_notice( __( 'Please enter your name…', 'woocommerce' ), 'error' );
            		return false;
            		}
            	if ( empty( $_REQUEST['field-two'] ) ) {
            		wc_add_notice( __( 'Please enter your title…', 'woocommerce' ), 'error' );
            		return false;
            		}
            	return true;
            }
            add_action( 'woocommerce_add_to_cart_validation', 'multiple_field_validation', 1, 5 );
            

            Thanks

          2. zee February 2, 2015

            Can you please update the ‘multiple custom fields’ complete source file with validation function? Please, please!!

            1. Saravana Kumar K February 2, 2015

              Hi Zee,

              It’s been updated.

          3. zee February 2, 2015

            Kumar, my friend, you are awesome!!!! Many thanks!!!

          4. zee February 3, 2015

            Again, thank-you for quick reply and fixes.
            I have came across one more hurdle. My shop’s re-order functionality is not working. Do you think it’s fixable with your magic coding?
            Thanks,

  114. gabrielle January 4, 2015

    Hi, @Sark after few weeks of searching i finally find your post,and it works for me , its GREAT!, but ts really late in my GMT and i’m litttle blind, where is updated version of article? I try add more input fields , with the same results like Paul, sorry for bother you 🙂 I will fight to the death until i finish this
    I send you e-mail about second method for this tutorial,but not working for me, maybe useful for something, who knows…

    1. Saravana Kumar K January 4, 2015

      Hi Gabrielle,

      No problem, i will send you the complete code for adding multiple fields in Woocommerce Product Page.

    2. Saravana Kumar K January 4, 2015

      Hi,

      1) The lowercase letter problem, just remove the sanitize_title() from save_name_on_tshirt_field() like this

      WC()->session->set( $cart_item_key.'_name_on_tshirt',  $_REQUEST['name-on-tshirt'] );

      2) That “only shows the latest input values” problem, you can find the update at the end of the article under Update section.

    3. Sandie March 25, 2015

      Hi,
      Thanks a lot for your tutorial, what a great work !!! It’s working very well with one field.
      But i should be blind too, i don’t find the updated code for multiple fields… Could you send me the complete code please ?
      Thanks again !

      1. Saravana Kumar K March 25, 2015

        Hi Sandie,

        Here is the functions.php for multiple fields. you might also wanna take a look at this plugin WC Fields Factory developed by me for the same purpose.

        1. Sandie March 26, 2015

          Ok, thanks for your plugin, it’s what i need ! 🙂
          Just a question : i would like to have a text field for number plate like this : AB-123-CD, is it possible to have fixed “-” ? Or should i do 3 fields with “-” between (but aligned) ?
          Thanks if you can help me (and sorry for my english 😉 )

  115. rasib January 2, 2015

    hi saravana can u plx let me know how to add text field in cart page ??

    1. Saravana Kumar K January 2, 2015

      Hi Rasib,
      You wanted to add text field on each cart line item.? or just an extra text field on cart page.?

      1. rasib January 5, 2015

        yes but i did it i use the hook and it works thnks mate

        1. rasib January 5, 2015

          Saravana i use this hoook woocommerce_cart_item_subtotal to add field but it override the total col i want to add field next to subtotal

          1. Saravana Kumar K January 5, 2015

            Hi Rasib,

            You need to append your input field with sub total.

            your hook function should look like this,

            function display_fieldd ( $cart_subtotal, $compound, $obj ) {
            	echo $cart_subtotal. '<br/><input type="text" value=""/>';
            }
            add_filter ( "woocommerce_cart_subtotal", "display_fieldd");
            
  116. Paul Moreton January 1, 2015

    Your update worked first time! You’re amazing 😀 Thank you so much for your help. I looked high and low for support with adding this functionality. You my friend are a life saver. Great way to start the new year. Now to launch my site. All the best for 2015.

    Kind regards
    Paul

    1. Saravana Kumar K January 1, 2015

      I am glad it helped. Happy New Year…

  117. Paul Moreton December 30, 2014

    Amazing thanks of much for your reply. The multi custom file on a product page now works 😀
    Sadly if I add more than one of the same product, it only shows the latest input values from my custom fields in cart page. Here’s my link of my test page – http://forgetfulmr.com/forgetful-mr-birthday-anniversary-subscription-basket/ – any ideas?
    Thanks so much for your help – I really appreciate it.
    Kind regards

    1. Saravana Kumar K December 30, 2014

      Hi paul,

      I got your problem, i have updated the article, you can find the solution under “Update” section.

  118. karthik December 29, 2014

    Hey,,, Great…. this was more helpful … Thanks:)

    1. Saravana Kumar K December 29, 2014

      I’m glad it helped.

  119. Paul Moreton December 28, 2014

    Also is there an easy way to add a second custom data field on each product page?

    Kind regards
    Paul

    1. Saravana Kumar K December 29, 2014

      Hi paul,
      Yes you can pass multiple values as an array, change the add_name_on_tshirt_field() as following.

      <input type="text" name="properties[name-on-tshirt]" value="" />
      <input type="text" name="properties[name-font-colour]" value="" />
      <input type="text" name="properties[name-font-size]" value="" />
      

      change save_name_on_tshirt_field() as following,

      $custom_data = $_REQUEST['properties'];
      WC()->session->set(  $cart_item_key.'_name_on_tshirt', sanitize_title(  $custom_data['name-on-tshirt']  )  );
      WC()->session->set(  $cart_item_key.'_name_font_colour', sanitize_title(  $custom_data['name-font-colour']  )  );
      WC()->session->set(  $cart_item_key.'_name_font_size', sanitize_title(  $custom_data['name-font-size']  )  );
      

      use appropriate key to render these multiple data in cart table and order review table.
      finally change tshirt_order_meta_handler() as following,

      wc_add_order_item_meta(  $item_id, "name_on_tshirt", WC()->session->get(  $cart_item_key.'_name_on_tshirt' )  );	
      wc_add_order_item_meta(  $item_id, "name_font_colour", WC()->session->get(  $cart_item_key.'_name_font_colour' )  );
      wc_add_order_item_meta(  $item_id, "name_font_size", WC()->session->get(  $cart_item_key.'_name_font_size' )  );
      

      hope it will help, if you have any difficulties let me know.
      Sark.

    Thanks for posting this article. It is exactly what I’ve been looking for!

    One minor thing – when adding two of the same products, with different variables (name 1 and name 2) it only remembers the variable of the last added product. Any thoughts?

    Kind regards
    Paul

    1. Saravana Kumar K December 29, 2014
