Get custom product attributes in Woocommerce

To retrieve custom product attributes in WooCommerce, you can use the get_post_meta() function. This function retrieves the value of a custom field for a given post ID.

Here is an example of how you could use get_post_meta() to retrieve a custom attribute for a product:

<?php

$product_id = 123;
$custom_attribute = get_post_meta($product_id, 'custom_attribute', true);

In this example, $product_id is the ID of the product for which you want to retrieve the custom attribute. The second argument, 'custom_attribute', is the name of the custom attribute. The third argument, true, specifies that you want the function to return a single value, rather than an array.

You can then use the $custom_attribute variable to access the value of the custom attribute.

Keep in mind that this will only work for custom attributes that have been added to the product using the WordPress custom fields functionality. If the custom attribute was added using a different method, you will need to use a different approach to retrieve it.
