I've added a custom field for each woocommerce product variation.
I've added a datetime input field. Then I will need to auto delete the variation when the datetime value is already past. So auto expire the woocommerce product variation.
This is my code for adding the custom input field.
// Add Variation Settings
add_action( 'woocommerce_product_after_variable_attributes', 'variation_settings_fields', 10, 3 );
// Save Variation Settings
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );
//Create New fields for Variations
function variation_settings_fields( $loop, $variation_data, $variation ) {
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field_date_expire[' . $variation->ID . ']',
'class' => '_text_field_date_expire',
'type' => 'datetime-local',
'label' => __( 'Date of Expiration', 'woocommerce' ),
'placeholder' => '',
'desc_tip' => 'true',
'description' => __( 'Expiration of Each Product Variation', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_text_field_date_expire', true )
)
);
}
//Save New Fields for Variation
function save_variation_settings_fields( $post_id ) {
// Text Field
$text_field = $_POST['_text_field_date_expire'][ $post_id ];
if( ! empty( $text_field ) ) {
update_post_meta( $post_id, '_text_field_date_expire', esc_attr( $text_field ) );
}
}
How could I get the input field value per each variations and echo it, so I could use the value for another function and delete the variations automatically?
you can get custom woocommerce product variation field by using get_post_meta() function
echo get_post_meta( $post->ID, '_text_field_date_expire', true );

I have been able to add a custom text input field to the variations of my variable products using the following code:
// Add custom text input field to admin Product Data > Variations
add_action( 'woocommerce_variation_options_pricing', 'add_custom_field_to_variations', 10, 3 );
function add_custom_field_to_variations( $loop, $variation_data, $variation ) {
woocommerce_wp_text_input( array(
'id' => 'custom_field[' . $loop . ']',
'class' => 'short',
'label' => __( 'product size', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, 'custom_field', true )
) );
}
// Save custom field on product variation save
add_action( 'woocommerce_save_product_variation', 'save_custom_field_variations', 10, 2 );
function save_custom_field_variations( $variation_id, $i ) {
$custom_field = $_POST['custom_field'][$i];
if ( isset( $custom_field ) )
update_post_meta( $variation_id, 'custom_field', esc_attr( $custom_field ) );
}
// Store custom field value into variation data
add_filter( 'woocommerce_available_variation', 'add_custom_field_variation_data' );
function add_custom_field_variation_data( $variations ) {
$variations['custom_field'] = '<div class="woocommerce_custom_field">Custom Field: <span>' .
get_post_meta( $variations[ 'variation_id' ], 'custom_field', true ) . '</span></div>';
return $variations;
}
The code works and save inputed variation values (see the screenshot below).
Now here is my code attempt to get and display custom field value in additional information tab:
function yourprefix_woocommerce_display_product_attributes($variation_data, $variations){
$variation_data['custom_field'] = [
'label' => __('size', 'text-domain'),
'value' => get_post_meta($variations->ID, 'custom_field', true),
];
return $variation_data;
}
add_filter('woocommerce_display_product_attributes', 'yourprefix_woocommerce_display_product_attributes', 10, 2);
But it does not show the value I entered in variation.
Any help is appreciated.
Your code is a bit outdated, and there are some mistakes and missing things: Some additional jQuery code is required to display the selected variation "Size" custom field value in additional Information tab.
You should always name custom field field key with an explicit slug.
Here is the complete revisited code:
// Admin Product > Variations: Display an input text field
add_action( 'woocommerce_variation_options_pricing', 'add_admin_product_variations_custom_field', 10, 3 );
function add_admin_product_variations_custom_field( $loop, $variation_data, $variation ) {
woocommerce_wp_text_input( array(
'id' => 'size[' . $loop . ']',
'class' => 'short',
'label' => __( 'product size', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_size', true )
) );
}
// Admin Product > Variations: Save input text field submited value
add_action( 'woocommerce_admin_process_variation_object', 'save_admin_product_variations_custom_field', 10, 2 );
function save_admin_product_variations_custom_field( $variation, $i ) {
if ( isset($_POST['size'][$i]) ) {
$variation->update_meta_data( '_size', sanitize_text_field($_POST['size'][$i]) );
}
}
// Frontend Variable products: Link variation custom field value
add_filter( 'woocommerce_available_variation', 'set_available_variation_custom_field', 10, 3 );
function set_available_variation_custom_field( $variation_data, $product, $variation ) {
return array_merge( $variation_data, array(
'size' => $variation->get_meta('_size'),
) );
}
// Frontend Variable products > additional information tab: Display "Size" label with an empty value
add_filter( 'woocommerce_display_product_attributes', 'Display_custom_field_label_with_empty_value', 10, 3 );
function Display_custom_field_label_with_empty_value( $product_attributes, $product ) {
$product_attributes[ 'size' ] = array(
'label' => __('Size', 'text-domain'),
'value' => '',
);
return $product_attributes;
}
// Variable Product (jQuery): Selected variation displays custom field value
add_action( 'woocommerce_before_variations_form', 'custom_variations_js_script' );
function custom_variations_js_script() {
wc_enqueue_js( "jQuery( function($){
var sizeObj = $('tr.woocommerce-product-attributes-item--size > td');
$('form.variations_form').on('show_variation', function(event, data){
sizeObj.text(data.size);
}).on('hide_variation', function(){
sizeObj.text('');
})
});" );
}
Code goes in functions.php file of the active child theme (or active theme). Tested and works.
Using the Remi Coulson tutorial, a custom field has been added for product variations.
This works, however the custom field is positioned by the add-to-cart button. I wish to position it within Additional Information tab. I have tried adding the front end code to the additional-information.php but it does not display.
<div class="woocommerce-variation-custom-text-field">
{{{ data.variation.text_field }}}
</div>
Added to functions.php to display variation
// Add Variation Settings
add_action( 'woocommerce_product_after_variable_attributes', 'variation_settings_fields', 10, 3 );
// Save Variation Settings
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );
/**
* Create new fields for variations

*/
function variation_settings_fields( $loop, $variation_data, $variation ) {
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field[' . $variation->ID . ']',
'label' => __( 'My Text Field', 'woocommerce' ),
'placeholder' => 'http://',
'desc_tip' => 'true',
'description' => __( 'Enter the custom value here.', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_text_field', true )

$text_field = $_POST['_text_field'][ $post_id ];

update_post_meta( $post_id, '_text_field', esc_attr( $text_field ) );
}

function load_variation_settings_fields( $variations ) {
// duplicate the line for each field
$variations['text_field'] = get_post_meta( $variations[ 'variation_id' ], '_text_field', true );
return $variations;
}
Note that your code is a bit outdated since WooCommerce 3.
jQuery and some other changes are required to display the selected variation custom field value anywhere in a specific location on single product pages, specially outside the variation form.
In the example below the selected variation custom field value will be displayed on "Additional information" product tab after product attributes table.
Here is the complete revisited code:
// Add a custom field to variation settings
add_action( 'woocommerce_product_after_variable_attributes', 'variation_settings_fields', 10, 3 );
function variation_settings_fields( $loop, $variation_data, $variation ) {
woocommerce_wp_text_input( array(

$variation->update_meta_data( '_text_field', sanitize_text_field($_POST['_text_field'][$loop]) );
}
}
// Add variation custom field to single variable product form
add_filter( 'woocommerce_available_variation', 'add_variation_custom_field_to_variable_form', 10, 3 );
function add_variation_custom_field_to_variable_form( $variation_data, $product, $variation ) {
$variation_data['text_field'] = $variation->get_meta('_text_field');
return $variation_data;
}
add_action( 'woocommerce_product_additional_information', 'add_html_container_to_display_selected_variation_custom_field' );

We have added a select field to simple products, so that we can define the price unit and display the unit after the price on the single product page. This works fine.
Additionally we have added a select field for variable products to define the price unit of each variation. This price unit should be displayed after the variation price on the product page:
<?php
function mytheme_woo_add_custom_variation_fields( $loop, $variation_data, $variation ) {
echo '<div class="options_group form-row form-row-full">';
$value = get_post_meta( $post->ID, '_variable_select_field', true );
if( empty( $value ) ) $value = '';
// Select
woocommerce_wp_select(
array(
'id' => '_variable_select_field[' . $variation->ID . ']',
'label' => __( 'Mengeneinheit', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_variable_select_field', true ),
'options' => array(
'' => __( 'ohne', 'woocommerce' ),
'Stück' => __( 'Stück', 'woocommerce' ),
'Paar' => __( 'Paar', 'woocommerce' ),
'Karton' => __( 'Karton', 'woocommerce' ),
'Packung' => __( 'Packung', 'woocommerce' ),
'Set' => __( 'Set', 'woocommerce' ),
'lfm' => __( 'Laufmeter', 'woocommerce' ),
'm²' => __( 'm2', 'woocommerce' ),
)
)
);
echo '</div>';
}
// Variations tab
add_action( 'woocommerce_variation_options_pricing', 'mytheme_woo_add_custom_variation_fields', 10, 3 );
// Add custom field for variations
function load_variation_settings_fields( $variations ) {
$variations['_variable_select_field'] = get_post_meta( $variations[ 'variation_id' ], '_variable_select_field', true );
return $variations;
}
add_filter( 'woocommerce_available_variation', 'load_variation_settings_fields' );
//Save variable product field
function mytheme_woo_add_custom_variation_fields_save( $post_id ){
$woocommerce_select_field = $_POST['_variable_select_field'][ $post_id ];
update_post_meta( $post_id, '_variable_select_field', esc_attr( $woocommerce_select_field ) );
}
add_action( 'woocommerce_save_product_variation', 'mytheme_woo_add_custom_variation_fields_save', 10, 2 );
/* Display the custom field after the price */
function mytheme_display_woo_custom_fields( $price ){
global $post, $product;
if ( $product->is_type( 'variable' ) ){
$variation_price_unit = get_post_meta( $post->ID, '_variable_select_field', true );
$price .= $variation_price_unit;
}
return $price;
}
add_action( 'woocommerce_get_price_html', 'mytheme_display_woo_custom_fields', 15 );
However, it does not work , I cannot find the right way to do that.
Can anyone let me know how to display the saved value from the product variation after the price?
Thank you!
This simple code snippet will display after selected variation price the related price unit as follows:
add_filter( 'woocommerce_available_variation', 'display_price_unit_after_variations_price_html', 10, 3) ;
function display_price_unit_after_variations_price_html( $data, $product, $variation ) {
if ( $mengeneinheit = $variation->get_meta('_variable_select_field') )
$data['price_html'] .= ' ' . $mengeneinheit;
return $data;
}
Code goes in functions.php file of the active child theme (or active theme). Tested and works.
You should rename the key _variable_select_field everywhere with for example _mengeneinheit as it will be more explicit (or in english _price_unit).
We managed to put a custom field for variation products following Remi Corson guide here
At this point, we are able to show the custom text field in the single product page when users select the variation, but this is not enough in the purchase process since we need to:
A) Display this text in Cart and Checkout
B) Save this information so it shows in Thank You Page, Emails and Admin Order Edit Page
Something similar to Save and display product custom meta on WooCommerce orders and emails, but with product variations instead of simple products.
This is the code we added to our functions.php to add the custom field to the product variations
// Add Variation Settings
add_action( 'woocommerce_product_after_variable_attributes', 'variation_settings_fields', 10, 3 );
// Save Variation Settings
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );
/**
* Create new fields for variations
*
*/
function variation_settings_fields( $loop, $variation_data, $variation ) {
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field[' . $variation->ID . ']',
'label' => __( 'My Text Field', 'woocommerce' ),
'placeholder' => 'http://',
'desc_tip' => 'true',
'description' => __( 'Enter the custom value here.', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_text_field', true )
)
);
// Hidden field
woocommerce_wp_hidden_input(
array(
'id' => '_hidden_field[' . $variation->ID . ']',
'value' => 'hidden_value'
)
);
}
/**
* Save new fields for variations
*
*/
function save_variation_settings_fields( $post_id ) {
// Text Field
$text_field = $_POST['_text_field'][ $post_id ];
if( ! empty( $text_field ) ) {
update_post_meta( $post_id, '_text_field', esc_attr( $text_field ) );
}
// Hidden field
$hidden = $_POST['_hidden_field'][ $post_id ];
if( ! empty( $hidden ) ) {
update_post_meta( $post_id, '_hidden_field', esc_attr( $hidden ) );
}
}
// Add New Variation Settings
add_filter( 'woocommerce_available_variation', 'load_variation_settings_fields' );
/**
* Add custom fields for variations
*
*/
function load_variation_settings_fields( $variations ) {
// duplicate the line for each field
$variations['text_field'] = get_post_meta( $variations[ 'variation_id' ], '_text_field', true );
return $variations;
}
So the goal here is how can we show this custom field for each variation in the Cart and Checkout below the items (Something like the image below - Look at the Shipping delay notice)
And to save that custom field info that each variation has to the Thank You Page, Emails and Order Page (We did it for simple products with this code, but this doesn't work for variable ones)
// Save and display "Custom Field for Simple Products" on order items everywhere
add_filter( 'woocommerce_checkout_create_order_line_item', 'action_wc_checkout_create_order_line_item', 10, 4 );
function action_wc_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
// Get the Custom Field
$value = $values['data']->get_meta( 'custom_field_for_simple_products' );
if( ! empty( $value ) ) {
// Save it and display it
$item->update_meta_data( __( 'Custom Fields', 'woocommerce' ), $value );
}
}
Please help!!

I've already had this code on functions.php
This code is to add a new field on each product variation to have datetime input field, so variations would automatically expired when the current date is past the input date.
// Add Variation Settings
add_action( 'woocommerce_product_after_variable_attributes', 'variation_settings_fields', 10, 3 );
// Save Variation Settings
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );
//Create New fields for Variations
function variation_settings_fields( $loop, $variation_data, $variation ) {
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field_date_expire[' . $variation->ID . ']',
'class' => '_text_field_date_expire',
'type' => 'datetime-local',
'label' => __( 'Date of Expiration', 'woocommerce' ),
'placeholder' => '',
'desc_tip' => 'true',
'description' => __( 'Expiration of Each Product Variation', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_text_field_date_expire', true )
)
);
}
//Save New Fields for Variation
function save_variation_settings_fields( $post_id ) {
// Text Field
$text_field = $_POST['_text_field_date_expire'][ $post_id ];
if( ! empty( $text_field ) ) {
update_post_meta( $post_id, '_text_field_date_expire', esc_attr( $text_field ) );
}
}
This is to add a new field on each variation of Wocommerce.
What I am trying to do is to get each "_text_field_date_expire" meta so I could delete expired variation for each of the products..
How do I get each woocommerce variation ID on functions.php so I could add a rule that it will expire when it is already past the current date right now?
var_dump(get_post_meta( $variation_id , '_text_field_date_expire', true ));
This code is the one that I will use to get the datetime field, but not sure how I could get each $variation_id field?
Try this one:
$args = array(
'post_type' => 'product_variation',
'post_status' => array( 'private', 'publish' ),
'numberposts' => -1,
'orderby' => 'menu_order',
'order' => 'asc',
'post_parent' => get_the_ID() // get parent post-ID
);
$variations = get_posts( $args );
foreach ( $variations as $variation ) {
// get variation ID
$variation_ID = $variation->ID;
// get variations meta
$product_variation = new WC_Product_Variation( $variation_ID );
// get variation featured image
$variation_image = $product_variation->get_image();
// get variation price
$variation_price = $product_variation->get_price_html();
get_post_meta( $variation_ID , '_text_field_date_expire', true );
}
Hope this will helps you. For more information:
How To Get Product Variations & Meta – WooCommerce
How to get the Variation ID in a Woocommerce product
In WooCommerce 3+, it's $variation->get_id() from $variation function argument, which is an instance of the WC_Product_Variation.
The method get_id() is inherited from WC_Data class.
So in your code it should be instead:
'id' => '_text_field_date_expire[' . $variation->get_id() . ']',
Since WooCommerce 3, All WC_Product properties can't be accessed directly. Instead, you need to use the available methods.
Also in your hooked function save_variation_settings_fields() you are declaring 2 arguments, so there is one missing. It should be:
//Save New Fields for Variation// Save Variation Settings
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );
function save_variation_settings_fields( $variation_id, $i ) {
// Text Field
$text_field = $_POST['_text_field_date_expire'][ $variation_id ];
if( ! empty( $text_field ) ) {
update_post_meta( $variation_id, '_text_field_date_expire', esc_attr( $text_field ) );
}
}
See the source code for woocommerce_save_product_variation action hook
