Your ajax hook add_action(‘wp_ajax_load_user_feed’, ‘ajax_load_user_feed’); is for logged in users only, if you want none logged in users (guests or visitors) then add: add_action(‘wp_ajax_nopriv_load_user_feed’, ‘ajax_load_user_feed’); and you should be fine.

Just like in Adding a Taxonomy Filter to Admin List for a Custom Post Type? the filter parse_query could be used, but here I’m using posts_where. The row All | Published | … is controlled by views_edit-{$post_type} and the $views array contains each item that’s a simple anchor tag. First, we insert a couple of … Read more
You must use $list_obj->prepare_items() before $list_obj->search_box(‘Search’, ‘search’) function! Example: <form method=”post”> <input type=”hidden” name=”page” value=”<?php echo $_REQUEST[‘page’]; ?>” /> <?php $this->sales_obj->prepare_items(); $this->sales_obj->search_box(‘Search’, ‘search’); $this->sales_obj->display(); ?> </form>

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.

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.
Yes I recently ran into the situation where I wanted to change the profile link in the user-info section of the admin bar. The problem is that you can only get all nodes, add and remove them. Not edit. And you also cannot modify the $wp_admin_bar->nodes property due it is private. When easily removing and … Read more
The show_in_admin_all_list parameter in the register_post_status() function, determines if a given post status is included in the All post table view. Probably the shortest version is: add_action( ‘init’, function() use ( &$wp_post_statuses ) { $wp_post_statuses[‘draft’]->show_in_admin_all_list = false; }, 1 ); but let’s avoid modifying the globals directly like this and override the default draft status … Read more
