Add custom Taxonomies to Single Variations

If you want to add custom taxonomies to your product variations, you can use the “woocommerce_single_variations_taxonomies” filter. An example how to add the product brand taxonomy can be found here:

/**
 * Add product_brand to taxonomies list for variations.
 *
 * @param array $taxonomies
 *
 * @return array
*/
add_filter( 'woocommerce_single_variations_taxonomies', 'add_custom_taxonomies', 10, 1 );
function add_custom_taxonomies( $taxonomies ) {
   $taxonomies[] = 'product_brand';
   return $taxonomies;
}

After you have placed this function in your child theme functions.php file. Make sure you click on “init” in plugin admin settings again.

I added a custom taxonomy using JetEngine, and it seems that this solution doesn’t work with JetEngine.
Besides, is there an option/possibility to display attributes that are not used for variations? Should they also be copied to the variation? And is there maybe a possibility of displaying all the metadata assigned to a variation (for debugging)?

add_filter( ‘woocommerce_single_variations_taxonomies’, ‘add_custom_taxonomies’, 10, 1 );
function add_custom_taxonomies( $taxonomies ) {
$taxonomies[] = ‘pwb-brand’;
return $taxonomies;
}

In my case I have perfect brand for woocommerce installed, how should I put the code?

You may ask the plugin developer what their taxonomy name is.
FileOctober 22, 2023
Thanks for the response, when you have the name of the taxonomy. Where should I replace the code?

Ok, thanks you. When I have the name of the taxonomy, how should I put it in the code?I must replace ‘product_brand’? 2 times in the code.

The parent attributes will be inherited, except the variation attributes of course..
Haavard H.November 23, 2022
Will this make the variations inherit the parent taxonomy values, or is it possible to set unique values per variation? For example a color attribute per single variation, without using this attribute to create the variation.

Hi, when I add product variants via Shortcode no CSS styling is loaded.

Any solution to this?

Thank you
