Laravel : Redirect the user to the same page after login

I have a cart products page, if a person clicks on a product add to cart button they will be redirected to the login page.

After a successful login, I need to send the user back to same products page again.

I used the following way in login controller.

But it's not actually working the way i want. Means it redirect to the index page again, I have used the return redirect()->back();

if (auth()->attempt(array('email' => $request->input('email'),
             'password' => $request->input('password'))))
 if(Auth::user()->name == 'Admin'){
                 return redirect()->to('home');
            }
            else{
           //     return redirect()->back();
                return redirect()->intended('/');
            }

How to solve the issue?
