Redirect when no parameter passed

No, so sorry. This $id.

PHP Code:

if (is_null($id) || empty($id)) {
      /*echo 'aaaaaa';
      die();*/
      return redirect()->to('/');
    } 


Do you have setAutoRoute() set to true and false in routing?

PS. You should look into using esc() as you are vulnerable to XSS.

That $id is the parameter of /deleteportfolio/$id ?

And I'll look esc() function
