How to programatically remove WordPress dashboard widgets

Simply paste the following into your functions.php file. The code will remove all dashboard widgets, so you should comment lines related to wigets you’d like to keep.

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']);

}

if (!current_user_can('manage_options')) {
	add_action('wp_dashboard_setup', 'remove_dashboard_widgets' );
}
