This thread is resolved. Here is a description of the problem and solution.
Problem: I would like to filter the list of Products by a custom taxonomy in wp-admin.
Solution: Add the following custom code to functions.php:
function filter_admin_lists_by_taxonomies( $post_type, $which ) {
// Array of post type slugs where these filters should appear
$filter_types = ['product'];
// Array of taxonomy slugs to filter by
$taxonomies = ['your-taxonomy-slug'];
if ( !in_array( $post_type, $filter_types ) )
return;
foreach ( $taxonomies as $taxonomy_slug ) {
// Retrieve taxonomy data
$taxonomy_obj = get_taxonomy( $taxonomy_slug );
$taxonomy_name = $taxonomy_obj->labels->name;
// Retrieve taxonomy terms
$terms = get_terms( $taxonomy_slug );
// Display filter HTML
echo "<select name='{$taxonomy_slug}' id='{$taxonomy_slug}' class='postform'>";
echo '<option value="">' . sprintf( esc_html__( 'Show All %s', 'text_domain' ), $taxonomy_name ) . '</option>';
foreach ( $terms as $term ) {
printf(
'<option value="%1$s" %2$s>%3$s (%4$s)</option>',
$term->slug,
( ( isset( $_GET[$taxonomy_slug] ) && ( $_GET[$taxonomy_slug] == $term->slug ) ) ? ' selected="selected"' : '' ),
$term->name,
$term->count
);
}
echo '</select>';
}
}
add_action( 'restrict_manage_posts', 'filter_admin_lists_by_taxonomies' , 10, 2);
Modify the $filter_types and $taxonomies arrays as needed.
