Unregister WordPress Dashboard Widgets

WordPress populates the administrator dashboard with a number of widgets by default. These include widgets to display incoming links, recent drafts, quick press, and a few more. If you want to remove these widgets, use the following code snippet in your functions.php file.

function remove_dashboard_widgets() {
	global $wp_meta_boxes;
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_quick_press']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_incoming_links']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_right_now']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_plugins']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_drafts']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_comments']);
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_primary']);
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_secondary']);
}
add_action('wp_dashboard_setup', 'remove_dashboard_widgets' );
