Redirects

- Redirecting to Controller Actions
- Redirecting with Flashed Session data
- Redirect in Constructor

There are several ways to redirect responses. The simplest method is to use the global redirect() helper.

Route::get('noprofile', function(){
  return redirect()->to('user/profile');
});

Or:

Route::get('noprofile', function(){
  return redirect('user/profile');
});

There is also a back() function to redirect the user to their previous location.

Route::post('user/profile', function(){
  // Validate the request...

  return back()->withInput();
});

Redirecting To Named Routes

Each Route can have a specific name. The name can be assigned using the name() method.
- Example:
1. In routes/web.php create a route for "/test" page, with the name "testing".
Create another route for "/redirect" which will redirect the request to the named route "testing".

Route::name('testing')->get('/test', function(){
   return 'Life is an effect, the cause is Love.';
});

Route::get('redirect',function(){
   return redirect()->route('testing');
});

2. Visit the following URL to test the named route example.

//localhost:8000/redirect

After execution of the above URL, you will be redirected to //localhost:8000/test , the location of the named route "testing".

If your route has parameters, you may pass them into an array as the second argument to the route() method.

// For a route with the following URI: profile/{id}

return redirect()->route('profile', ['id'=>1]);

Redirecting to Controller Actions

To redirect to controller actions, pass the controller and the method name to the action() function.

return redirect()->action('HomeController@index');

If your controller route requires parameters, you may pass them into an array as the second argument to the action() method:

return redirect()->action('UserController@profile', ['id'=>1]);

Redirecting with Flashed Session data

If you want to pass a message to the page where the user is redirected, for example after successfully performing an action, you may create a redirect response and flash data to the session using the with() method.

Route::post('user/profile', function(){
  // Update the user's profile...

  return redirect('dashboard')->with('status', 'Profile updated!');
});

After the user is redirected, you may display the flashed message from the session. For example, using Blade syntax:

@if(session('status'))
 <div class="alert-success">
  {{ session('status') }}
 </div>
@endif

After redirect with the with() method, the flashed session is automatically deleted from "session".

Redirect in Constructor

To make a redirect() from a __construct() of a controller, to make sure that the redirect() is performed, without executing other method, use: redirect()->send().

If you want to make a redirect in __construct() according to a session, use the $this->middleware() method in constructor, with the code for redirect in a callback function, like in this syntax.

public function __construct(){
  $this->middleware(function($request, $next){
    //Your code with Session, for redirect

    return $next($request); //<- this is required
  });
}

- Example, a piece of code from a controller. If the Session 'admin_logg' not exist, it will redirect to '/'; the test() method will not be executed:

public function __construct(Request $request){
  //this Closure is needed because it is used session in __construct
  $this->middleware(function($request, $next){
    if(!session()->has('admin_logg')){
      return redirect('/')->send();
    }
    return $next($request);
  });

  $this->test();
}

public function test(){
  echo 'Laravel tutorial';
}
