WP Rest API – Upload media without saving attachment post

Based on your comment you appear to be using the REST API. There’s no hook between uploading the file and creating the attachment post that could be used for this purpose in the API endpoint.

The issue is that you are mixing up the $title variables. $title is the parameter passed to the new_title function, but then you use it as an array: $title[‘custom_version’]. Try this: add_filter(‘the_title’, ‘new_title’, 10, 2); function new_title($title, $id) { if(‘custom_version’ == get_post_type($id)) $title=”Application has been updated to v”.$title; return $title; } I’d also highly recommend … Read more

Display WooCommerce newest product reviews on top [closed]

I couldn’t find this documented anywhere, but the solution is pretty simple. In single_product_review.php, the arguments passed to wp_list_comments are filtered: wp_list_comments( apply_filters( ‘woocommerce_product_review_list_args’, array( ‘callback’ => ‘woocommerce_comments’ ) ) ); by adding reverse_top_level to the arguments, the order is reversed.
