Woocommerce - Sortable custom taxonomy

wc-sortable-custom-taxonomy.php

<?php
// This is so easy, it's embarassing that I took 20 minutes to find it.
// "Catalog" is a custom taxonomy.
function make_catalog_sortable( $sortables ) {
    $sortables[] = 'catalog';
    return $sortables;
}
add_filter( 'woocommerce_sortable_taxonomies', 'make_catalog_sortable' );

you can then get the sortable taxonomies like this:
$terms = get_the_terms($post->ID, 'catalog'); if (!empty($terms) && is_array($terms)) { $post_terms = array(); foreach ($terms as $term) { $post_terms[] = $term->term_id; } $categories = get_terms('catalog', array( 'orderby' => 'name', 'menu_order' => 'asc', 'include' => $post_terms, )); }
