WordPress is a powerful tool to create any type of website. It is a preferred choice of many developers and even clients who don’t have much knowledge of WordPress.

Being a developer, I am sure, you want to provide a simple admin panel to your client without any extra menu items. So, here I will show you how to remove the Tools menu item from Admin Menu for a specific User Role.

Suppose, you have created a user role “owner” and you want to hide the Tools menu item from it’s admin panel. Just copy & paste the following code in your functions.php file.
Replace the ‘owner’ role with the slug of your custom role.

add_action( 'admin_init', 'ad_remove_menu_pages' );
function ad_remove_menu_pages() {
  global $current_user;
  $user_roles = $current_user->roles;
  if ( $user_roles[0] == 'owner' ) {
    remove_menu_page( 'tools.php' );
  }
}

Please note that, this only hides the link from the menu. The page will be still accessible by direct link.
