one way could be to use the construct()method in the Controllers used for admin tasks like so:

public function __construct()
{
    parent::__construct();
    $this->beforeFilter('admin');
}

and then you filter it eg

Route::filter('admin', function()
{
	if (Auth::user()->admin != 1) return Redirect::to('/');
});

which, in this case, assumes you have an admin field set up in your users table with a boolean 1 or 0

Thank u, watched about middleware yesterday evening.

Fine for me.

If you need a little bit more control you can try Laraguard. It's a permission module I wrote to protect controllers and/or methods and quite easy to use.
