There is no need to change the the_author() function itself. A simple conditional tag will do the trick. Example: <?php /*** on your functions.php file ***/ function ifRegistered() { if(is_user_logged_in()) { the_author(); } else { echo get_the_post_meta($post->ID, ‘your_post_meta_key’, true); // or anything else, of course } } /*** on the template you want to use … Read more

So I’ve managed to solve this. The googl_shortlink function from above now looks like this: function googl_shortlink($url, $post_id = false) { global $post; if (!$post_id && $post) $post_id = $post->ID; elseif ($post_id) $post = get_post($post_id); // list all the active languages in an array $enabled_languages = get_option(‘qtranslate_enabled_languages’); if (is_404()) return; if ($post && $post->post_status != … Read more
This “not exists” functionality isn’t possible using a regular meta query. It’s being worked on, but it looks like it’s been shuffled to a future release (see this trac ticket for more insight).
