How to Remove All Widgets from Dashboard?

2 comments

1. 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'] = array();
       $wp_meta_boxes['dashboard']['side']['core'] = array();
   }

   The answer to force one column as a screen option is from here:

   add_filter( 'get_user_option_screen_layout_dashboard', 'wpse_4552_one_column_layout' );
   
   function wpse_4552_one_column_layout( $cols ) {
       if( current_user_can( 'basic_contributor' ) )
           return 1;
       return $cols;
   }

   This one provided the code to hide the Screen Options and the Help tabs:

   add_filter( 'contextual_help', 'wpse_25034_remove_dashboard_help_tab', 999, 3 );
   add_filter( 'screen_options_show_screen', 'wpse_25034_remove_help_tab' );
   
   function wpse_25034_remove_dashboard_help_tab( $old_help, $screen_id, $screen )
   {
       if( 'dashboard' != $screen->base )
           return $old_help;
   
       $screen->remove_help_tabs();
       return $old_help;
   }
   
   function wpse_25034_remove_help_tab( $visible )
   {
       global $current_screen;
       if( 'dashboard' == $current_screen->base )
           return false;
       return $visible;
   }

   Ok, now there’s almost nothing in the Dashboard, what’s next?

   A bit of CSS to hide the icon-index and H2 title, and some jQuery to fill the void:

   add_action( 'admin_head-index.php', 'wpse_73561_dashboard_scripts' );
   
   function wpse_73561_dashboard_scripts() {
       ?>
           <style>#icon-index, .wrap h2 {display:none}</style>
           <script language="javascript" type="text/javascript">
               jQuery(document).ready(function($) {
                   fillTheVoid(); // soon in StackOverflow 
               });
           </script>   
       <?php
   }
   

   _{[ update ]}

   The filled void can be found in StackOverflow.
   Use that wpse_73561_dashboard_scripts function instead of this one.

2. This will work fine

   add_action('wp_dashboard_setup', 'remove_dashboard_widgets' );
   function remove_dashboard_widgets() {
   
       global $wp_meta_boxes;
       unset($wp_meta_boxes['dashboard']);
   
   }
