Well it wouldn’t always work unless you global $user_id. is_user_logged_in will however work without that extra line of code. The speed improvement is most likely so small it’s less than the speed improvement between single and double quotes and not even worth thinking about. Also $user_id variable may disappear in a new version and would … Read more
You need to change orderby value to meta_value in event_date_column_orderby, also I am not sure about the get(‘event_date’) you are using, so I have replaced it in the code below to get_post_meta. I have just tested the code below and it sorts by dates just fine. // Register a new column in the admin Post … Read more
This is impossible to answer definitively without a better description, but I am assuming that app.php is a completely distinct piece of code. In which case, WordPress can’t really manage access to it. You will need to incorporate it into WordPress. While this is not the only way to do it I would advise: Create … Read more
Ah, I get it. When you enqueue your admin script, add ‘wp-util’ as a dependancy. wp_enqueue_script( ‘script_handle’, plugin_dir_url( __FILE__ ) . ‘script.js’, array( ‘jquery’, ‘wp-util’ ), ‘1.0’, true );
Yes, try this : function remove_editor() { if (isset($_GET[‘post’])) { $id = $_GET[‘post’]; $template = get_post_meta($id, ‘_wp_page_template’, true); switch ($template) { case ‘template_01.php’: case ‘template_02.php’: case ‘template_03.php’: case ‘template_04.php’: // the below removes ‘editor’ support for ‘pages’ // if you want to remove for posts or custom post types as well // add this line … Read more
You can use the remove_submenu_page function: add_action( ‘admin_init’, ‘wpse_38111’ ); function wpse_38111() { remove_submenu_page( ‘index.php’, ‘update-core.php’ ); }
The box gets added in wp_nav_menu_setup(), so you’ll have to remove it sometime after that and before it’s being output later in nav-menus.php. There don’t seem to be any action hooks you can use there, but admin-header.php has a few. You could try this: add_action( ‘admin_head-nav-menus.php’, ‘roots_remove_nav_menu_metaboxes’ ); I’ve never tried removing metaboxes from the … Read more
Why are my styles being applied to the admin area? Assuming that is all of the code, it is because you are enqueueing the styles globally. You need to hook that to wp_enqueue_scripts, which will only load on the front end. wp_register_style( ‘main-styles’, get_stylesheet_directory_uri() . ‘/css/styles.css’, false, ‘1.0.0’, ‘all’); function enqueue_script_front_wpse_84975() { wp_enqueue_style(‘main-styles’); } add_action(‘wp_enqueue_scripts’, … Read more
You can manipulate the global variable $submenu and remove them. In normal circumstances, the index key values are 5 (All items) and 10 (New item). In this example, the post type is portfolio: add_action( ‘admin_init’, ‘remove_cpt_submenus_wpse_95797’ ); function remove_cpt_submenus_wpse_95797() { global $submenu; unset( $submenu[‘edit.php?post_type=portfolio’][5], $submenu[‘edit.php?post_type=portfolio’][10] ); }
By adding a filter to the ‘post_link’ hook. See the get_permalink() function for more info. For custom post types, you can use the ‘post_type_link’ hook. It’s a lot easier if you follow the source code (this is for v3.0): http://core.trac.wordpress.org/browser/branches/3.0/wp-includes/link-template.php#L166
