I need to modify the WooCommerce product query because I want to filter the shown products on the shop pages based on the taxonomies for each product. So what I've tried is this here:
add_filter( 'woocommerce_product_query_meta_query', 'filter', 10, 2 );
function filter( $meta_query, $query ) {
// Only on category pages
if ( ! is_product_category() ) {
return $meta_query;
}
$tags_array[] = 'ABCSD';
$meta_query[] = array(
'key' => 'product_tag',
'value' => $tags_array,
'compare' => 'EXIST'
);
return $meta_query;
}
So I just want to display all products which have the taxonomy ABCSD in it. The code is placed in my functions.php. What I'm doing wrong here?
