How to add custom columns to Custom Post Type admin screen

The code from ThinkVitamin is right. I think the problem came from else where in your code. Actually, the hook manage_edit-${post_type}_columns takes an argument $columns which is an array of all registered columns. To add a new column, just add a new element to this array, like this: add_filter(‘manage_edit-film_columns’, ‘my_columns’); function my_columns($columns) { $columns[‘views’] = … Read more

White screen of death only in wp-admin

As a rule of thumb, always remove the ending ?> of your .php files, especially if it’s a functions or config file that gets parsed before headers are sent to the page. If after that ?> you accidentally add a space, a tab character or a new line, there’s your invisible error.

Exclude drafts in all() view of edit.php

The show_in_admin_all_list parameter in the register_post_status() function, determines if a given post status is included in the All post table view.

How to Remove All Widgets from Dashboard?

From this Q&A, I’ve learned about the global variable $wp_meta_boxes. And over there is also the code to remove the default meta boxes. After examining the variable, this is the code I wrote to remove all Dashboard Widgets, including the ones added by plugins: add_action(‘wp_dashboard_setup’, ‘wpse_73561_remove_all_dashboard_meta_boxes’, 9999 ); function wpse_73561_remove_all_dashboard_meta_boxes() { global $wp_meta_boxes; $wp_meta_boxes[‘dashboard’][‘normal’][‘core’] = … Read more

Is there un-wp_autop function?

I just ran into this situation. Here is a function I used to undo wpautop. I might be missing something, but this is a good start: function reverse_wpautop($s) { //remove any new lines already in there $s = str_replace(“\n”, “”, $s); //remove all <p> $s = str_replace(“<p>”, “”, $s); //replace <br /> with \n $s … Read more
