How to pass multiple parameters to middleware with OR condition in Laravel 5.2

Question

I am trying to set permission to access an action to two different user roles Admin, Normal_User as shown below.

Route::group([\'middleware\' => [\'role_c

Instead of adding multiple arguments to your handle method and having to update it every time you add a new role to your application, you can make it dynamic.

Middleware

 /**
 * Handle an incoming request.
 *
 * @param $request
 * @param Closure $next
 * @return \Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector
 */
public function handle($request, Closure $next) {

    $roles = array_slice(func_get_args(), 2); // [default, admin, manager]

    foreach ($roles as $role) {

        try {

            Role::whereName($role)->firstOrFail(); // make sure we got a "real" role

            if (Auth::user()->hasRole($role)) {
                return $next($request);
            }

        } catch (ModelNotFoundException $exception) {

            dd('Could not find role ' . $role);

        }
    }

    Flash::warning('Access Denied', 'You are not authorized to view that content.'); // custom flash class

    return redirect('/');
}

Route

Route::group(['middleware' => ['role_check:default,admin,manager']], function() {
    Route::get('/user/{user_id}', array('uses' => 'UserController@showUserDashboard', 'as' => 'showUserDashboard'));
});

This will check if the authenticated user has at least one of the roles provided and if so, passes the request to the next middleware stack. Of course the hasRole() method and the roles themselves will need to be implemented by you.
