Reorder the Admin Menu in WordPress

A short snippet that lets you change the order of the menu in the WordPress dashboard. Simply choose the order you want in the $reordered_items array. You can use var_dump($menu_order) to find all menu items.

Items will appear under the top-level item (Dashboard).

add_filter('menu_order', 'reorder_admin_menu', 999);
 
/**
 * Reorders admin menu to match the wanted order
 *
 * @param $menu_order
 * @return mixed
 */
function reorder_admin_menu($menu_order) {
 
  $reordered_items = array(
    'edit.php?post_type=page',
    'edit.php'
  );
 
  $reordered_items_insertion_point = 'index.php';
 
  $filtered_menu_order = array_diff($menu_order, $reordered_items);
 
  $new_menu_order = array();
 
  foreach($filtered_menu_order as $menu_item) {
    $new_menu_order[] = $menu_item;
 
    if($menu_item === $reordered_items_insertion_point) {
      $new_menu_order = array_merge($new_menu_order, $reordered_items);
    }
  }
 
  return $new_menu_order;
}
