$cats_array = wp_get_post_terms($product->get_id(),'product_cat',array('fields'=>'ids')); $sub_cats = array (); for ( $i =0; $i < count($cats_array); $i++ ) { $args = array( 'hierarchical' => 1, 'show_option_none' => '', 'hide_empty' => 0, 'parent' => $cats_array[$i], 'taxonomy' => 'product_cat' ); foreach (get_categories($args) as $key) { $sub_cats[] = $key->term_id; } } $args = apply_filters( 'woocommerce_related_products_args', array( 'post_type' => 'product', 'ignore_sticky_posts' => 1, 'no_found_rows' => 1, 'posts_per_page' => $posts_per_page, 'orderby' => $orderby, 'post__in' => $related, 'post__not_in' => array( $product->get_id() ), 'tax_query' => array( array( 'taxonomy' => 'product_cat', 'field' => 'id', 'terms' => $sub_cats ) ) ) );
