Rather than modifying stored rules it would be more reliable to modify rules before they are stored. flush_rewrite_rules() calls WP_Rewrite->flush_rules() WP_Rewrite->wp_rewrite_rules() WP_Rewrite->rewrite_rules() Inside last there are fitting hooks to modify rules (after which result they will be saved as usual on each flush): do_action_ref_array(‘generate_rewrite_rules’, array(&$this)); $this->rules = apply_filters(‘rewrite_rules_array’, $this->rules);

With that in functions.php you’d probably have to declare $error to be global like so : if (‘POST’ == $_SERVER[‘REQUEST_METHOD’] && !empty($_POST[‘action’]) && $_POST[‘action’] == ‘registration’) { global $error; $error = new WP_Error(); // the rest of your code And then do global $error; again on your registration page before trying to use it. But … Read more
I found the solution: Replace if (!$url) $url = get_permalink($post->ID); with $post_id = get_the_ID(); $url = get_post_meta(“$post_id”, ‘links_link_custom’, true);
The code of WordPress states that the fourth variable with the add_image_size() function is value for the crop ‘mode’. If you that value to ‘false’ (which is default) it’ll keep the aspect ratio of your images. For example, if you set height and width to both 150×150 and have an image that is 300×200 will … Read more

The get_media_embedded_in_content() function is a handy helper function, though it doesn’t seem to be used in the core (ver. 4.2.2). Regular expression: To understand the get_media_embedded_in_content() function, we must understand the following regular expression: #<(?P<tag>video|audio|object|embed|iframe)[^<]*?(?:>[\s\S]*?<\/(?P=tag)>|\s*\/>)# There are many online regular-expression tools to help us with that. Like this one: Debuggex demo We note that it’s … Read more
