wp_loaded is called long, long before the post content is fetched. Put that code into a plugin. Also, you shouldn’t echo anything that early. The HTTP headers aren’t sent yet on wp_loaded, so you will get the Headers already sent error, and your user authentication will not work: you cannot log in anymore.
You can try the following approach using the the_title filter in the edit.php screen: /** * Modify post titles in the edit.php screen. * If the post title is empty, then show max 10 words from the post content instead. */ add_action( ‘load-edit.php’, function() { add_filter( ‘the_title’, function( $title ) { $post = get_post(); if( … Read more
Technically, you can’t. That filter doesn’t pass in any data that will specifically allow you to distinguish between those two cases. 2086 /** 2087 * Fires immediately after an existing user is updated. 2088 * 2089 * @since 2.0.0 2090 * 2091 * @param int $user_id User ID. 2092 * @param object $old_user_data Object containing … Read more
I’m running the most up to date version of WordPress which has made changes to how permalinks are displayed and handled. There’s no longer a View Post button. I was able to remove the whole area using the get_sample_permalink_html hook. Just return an empty string: function hide_permalink() { return ”; } add_filter( ‘get_sample_permalink_html’, ‘hide_permalink’ );

When you run this code: add_action( ‘post_footer’, ‘toms_footer_stuff’ ); You’re saying that when the post_footer event happens, run the toms_footer_stuff function. These functions take the form of: add_action( name_of_action, php_callable ); A PHP callable is something that can be called represented as an object. It can be any … Read more
you make a mistake in the call of add_action the last parameters must be changed from 1 to 2 add_action(‘pre_get_posts’,’shop_filter_cat’,10,2);
Extending the wpdb class We can create the db.php file under wp-content/ directory to override the wpdb class to our needs. I checked this site for such examples and found one by @MarkKaplun here. Here’s an example how one can get access to the last result, after each query has run: <?php /** * db.php … Read more
The admin_init hook is not fired when viewing pages in the frontend. So hooking register_post_type() to that action will lead to your custom post type (and with that all of its posts) not being available in the frontend at all. As of Rarst’s answer to another question, the admin_init hook gets fired shortly after the … Read more
It is included from /wp-settings.php right after the action setup_theme. Line number 423 as of WordPress 4.7
No, you shouldn’t, it’s deprecated I don’t think wp_signon() can fill my needs in the same way wp_login() can It does the exact same thing, but with a few new features I read this runs after the login of a user and contains 2 parameter of which one is the username. With the username I … Read more
