WooCommerce: Get Variation IDs By Product Category or Tag

We can get products belonging to a product category or product tag very easily. What’s much more difficult is getting single variations based on a product category or product tag, as variations… don’t have a category or tag, which belong to its “parent” variable product instead.

In this post, we will define a function that you can reuse in your custom code whenever you need to get all variation IDs based on a given product category or product tag. You can then loop through the array and return whatever info you need. Enjoy!

PHP Snippet: Retrieve List of Variations By Product Category or Tag

/** * @snippet Get Variation IDs By Taxonomy Term * @how-to Get CustomizeWoo.com FREE * @author Rodolfo Melogli * @compatible WooCommerce 7 * @donate $9 https://businessbloomer.com/bloomer-armada/ */ function get_variations_from_term( $term, $taxonomy, $type ) { global $wpdb; $ids = $wpdb->get_col( ” SELECT DISTINCT p.ID FROM {$wpdb->prefix}posts as p INNER JOIN {$wpdb->prefix}term_relationships as tr ON ( p.ID = tr.object_id OR p.post_parent = tr.object_id ) INNER JOIN {$wpdb->prefix}term_taxonomy as tt ON tr.term_taxonomy_id = tt.term_taxonomy_id INNER JOIN {$wpdb->prefix}terms as t ON tt.term_id = t.term_id WHERE p.post_type = ‘product_variation’ AND p.post_status = ‘publish’ AND p.ID NOT IN ( SELECT DISTINCT post_parent FROM {$wpdb->prefix}posts WHERE post_type = ‘product_variation’ AND post_status = ‘publish’ ) AND tt.taxonomy = ‘$taxonomy’ AND t.$type = ‘$term’ ” ); return $ids; }

You can then use the following in order to get the variation IDs by category or tag:

// BY PRODUCT CATEGORY get_variations_from_term( ‘chairs’, ‘product_cat’, ‘slug’ ); get_variations_from_term( 59, ‘product_cat’, ‘term_id’ ); // ETC // BY PRODUCT TAG get_variations_from_term( ‘shiny’, ‘product_tag’, ‘slug’ ); get_variations_from_term( ‘Super heavy’, ‘product_tag’, ‘name’ ); // ETC

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (delete “?>” if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files – if you need more guidance, please take a look at my free video tutorial “Where to Place WooCommerce Customization?”

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.
