Replacing the List table of a Post Type

2 comments

1. No, you cannot replace the list table. There is no filter, everything is hard-coded.

   But you can change the post type registration, set show_ui to FALSE to prevent the built-in page, and add a custom page for the post type listing to show the editable items.

   add_action( 'wp_loaded', function(){
       register_post_type(
           'test',
           array(
               'labels' => array(
                   'name' => 'TEST'
               ),
               'public' => TRUE,
               'show_ui' => FALSE
           )
       );
   });
   
   add_action( 'admin_menu', function(){
       add_object_page(
           'TEST',
           'TEST',
           'edit_test',
           'test',
           function(){
               echo 'test'; // list post type items here
           }
       );
   });

2. This example is applied to post post type. This is leveraging the WP_Posts_List_Table class and views-edit-{$post_type} filter. This seem isn’t the best way, but it works:

   Make sure the class is loaded on your page:

   if(!class_exists('WP_List_Table')){
       require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );
   }
   if(!class_exists('WP_Posts_List_Table')){
       require_once( ABSPATH . 'wp-admin/includes/class-wp-posts-list-table.php' );
   }
   

   Extend the WP_Posts_List_Table class to remove list table and define the custom content:

   class wpse_CustomTable extends WP_Posts_List_Table
   {       
       // remove search box
       public function search_box( $text, $input_id ){ }
   
       // Your custom list table is here
       public function display() {
           echo "Test";
       }
   }
   

   Use it inside a filter hook:

   // hook into `views-edit`
   add_filter( 'views_edit-post',  "sstssfb_custom_list_table");    
   // Override the post table object
   function sstssfb_custom_list_table() {
       global $wp_list_table;
       $mylisttable = new wpse_CustomTable();
       $wp_list_table = $mylisttable ;    
   }
   

   Result:
