Exclude 'hidden' queried products from carousel in WooCommerce 3+
Since Woocommerce 3 the product visibility is handled by the taxonomy product_visibility for the term exclude-from-catalog, so you need to add a tax query as follow:
$common_args = array( 'post_type' => 'product', 'posts_per_page' => !empty($posts_per_page) ? intval($posts_per_page) : 4, 'post_status' => 'publish', 'ignore_sticky_posts' => true, 'no_found_rows' => true, 'tax_query' => array( array( 'taxonomy' => 'product_visibility', 'terms' => array('exclude-from-catalog'), 'field' => 'name', 'operator' => 'NOT IN', ) ),);It should work. Tested this array of arguments with WordPress get_post() function (it works).
