To save a custom field of an attribute in WooCommerce, you can use the woocommerce_process_product_meta hook to save the custom field value when a product is saved or updated. You can retrieve the custom field value using the $_POST global variable and then update the attribute using the wp_set_object_terms function.


Here is an example code snippet to save a custom field for an attribute called "color":

add_action('woocommerce_process_product_meta', 'save_custom_attribute_field');

function save_custom_attribute_field($post_id){
    $color = isset( $_POST['_color'] ) ? $_POST['_color'] : '';
    
    if( !empty( $color ) ){
        $term = get_term_by('name', $color, 'pa_color');
        
        if( !$term ){
            $term = wp_insert_term($color, 'pa_color');
            $term_id = $term['term_id'];
        }else{
            $term_id = $term->term_id;
        }
        
        wp_set_object_terms($post_id, $term_id, 'pa_color');
    }
}


This code will save the value of the custom field "_color" as the attribute "color" for the product. Make sure to replace "pa_color" with the slug of the attribute taxonomy that you want to save the custom field value as.

// Get the product ID
$product_id = get_the_id();

// Get the custom field data for the attribute
$custom_field_data = get_post_meta($product_id, 'custom_attribute_field_name', true);

// Display the custom field data

In this code snippet:

  • $product_id is the ID of the product for which you want to retrieve the custom field data.
