The wp_insert_post_data filter can do that: add_filter( ‘wp_insert_post_data’ , ‘filter_post_data’ , ’99’, 2 ); function filter_post_data( $data , $postarr ) { // Change post title $data[‘post_title’] .= ‘_suffix’; return $data; }
you can try to use the script_loader_src filter hook e.g: add_filter(‘script_loader_src’,’add_id_to_script’,10,2); function add_id_to_script($src, $handle){ if ($handle != ‘dropbox.js’) return $src; return $src.”‘ id=’dropboxjs’ data-app-key=’MY_APP_KEY”; } Update i just figured it out myself that the src is escaped by esc_url, so looking a bit more i found the clean_url filter which you can use to return … Read more
Products in WooCommerce are a custom post type, so this should work: $url = get_permalink( $product_id ); You can treat that $product_id as a postID (that’s what it is), so you can use it with other normal WP functions, like: echo ‘<a href=”‘.get_permalink($product_id).'”>’.get_the_title($product_id).'</a>’;

Then it checks for all other active plugins by looking at the active_plugins entry of … Read more
If you edit your wp-config.php file you can preload these FTP settings as constants read by WordPress. Keep in mind, on a shared host, you should be mindful of possible security implications. See Editing wp-config.php for more information. Your settings will vary, but these work for me and my hosting setup. I’ve included some of … Read more
I don’t think get_categories() is the best option for you in this case because it returns a string with all the categories listed as anchor tags, fine for displaying, but not great for figuring out in code what the categories are. Ok, so the first thing you need to do is grab the product/post object … Read more
When developing a plugin should the functions be grouped together into a Class to avoid namespace conflicts? Yes, but that’s only one of the minor arguments. In-fact that’s not the “true” nature of a class in OOAD. Does using classes create performance overheads for PHP? No, not notably. Bad design and/or bad written code or … Read more
After a bit more slogging through code and Googling, I found the answer. It’s contained in this thread (see Otto42’s post), but for the record, adding the following to your plugin will override the 404 handling for the conditions you specify: add_filter(‘template_redirect’, ‘my_404_override’ ); function my_404_override() { global $wp_query; if (<some condition is met>) { … Read more
