Increase number of related products

  • Post per page is set at 12, but only 2 related products show. I added the following script to increase that to 4 – which works but it overrides the category/tag filter so products from all cats/tags are included. How can I modify this to show 4 products AND still filter by tag ?

    function woo_related_products_limit() {
global $product;
$args = array(
'post_type' => 'product',
'no_found_rows' => 1,
'posts_per_page' => 4,
'ignore_sticky_posts' => 1,
'orderby' => $orderby,
'post__in' => $related,
'post__not_in' => array($product->id)

);
return $args;
}

add_filter( 'woocommerce_related_products_args', 'woo_related_products_limit' );
