How do I pass data from LoginController to my HomeController? - laravel

Question

I want to pass my input information ($request->all()) from my LoginController to my HomeController. How can I do that? The LoginController is generated by Laravel scaffold.
LoginController:
<?php
namespace App\Http\Controllers\Auth;
use \Auth;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Auth\Authenticatable;
use Illuminate\Http\Request;
use App\Account;
class LoginController extends Controller
{
/*
|--------------------------------------------------------------------------
| Login Controller
|--------------------------------------------------------------------------
|
| This controller handles authenticating users for the application and
| redirecting them to your home screen. The controller uses a trait
| to conveniently provide its functionality to your applications.
|
*/
use AuthenticatesUsers;
/**
* Where to redirect users after login.
*
* #var string
*/
protected $redirectTo = '/home';
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct(Request $request)
{
$this->middleware('guest', ['except' => 'logout']);
}
/**
* Override the username method used to validate login
*
* #return string
*/
public function username()
{
return 'username';
}
}
HomeController in which dd($request->all() returns []
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Blog;
use App\Account;
use Illuminate\Foundation\Auth;
use Illuminate\Support\Facades\Input;
class HomeController extends Controller
{
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
//$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* #return \Illuminate\Http\Response
*/
public function index(Request $request)
{
$blogItems = Blog::all();
$onlinePlayers = Account::getOnlinePlayers()->count();
$onlineStaff = Account::getOnlineStaff()->count();
//return view('home.index', compact('blogItems', 'onlinePlayers', 'onlineStaff'));
return dd($request->all()); //This returns an empty array
}
}

Answer 1

Quick and dirty
The following method is a quick and dirty method. It relies on how Laravel's authentication is designed under the hood. If Laravel changes this in the next version, this may need to change with it.
In your LoginController, implement your own login() method. You will need to rename the login() method provided by the trait because we still want to call it:
class LoginController extends Controller
{
use AuthenticatesUsers {
login as traitLogin
}
public function login(Request $request)
{
$request->session()->flash('form_type', 'login');
return $this->traitLogin($request);
}
}
In your RegisterController, implement your own register() method. You will need to rename the register() method provided by the trait because we still want to call it:
class RegisterController extends Controller
{
use RegistersUsers {
register as traitRegister
}
public function register(Request $request)
{
$request->session()->flash('form_type', 'register');
return $this->traitRegister($request);
}
}
Now, in your HomeController, you can get the type of form that was submitted from the flashed session data.
class HomeController extends Controller
{
public function index(Request $request)
{
$form = $request->session()->get('form_type');
// the rest of your logic
}
}
Cleaner
In contrast to the method above, I would suggest using a hidden form value and a new middleware to process that form value.
This is a little bit cleaner because it doesn't rely on any of the built in Laravel authentication logic. If Laravel changes the name of the traits, the method names, the route actions, or the actual logic used inside the methods, it won't affect how this functionality is designed or how it works.
In your login and register forms, add a new hidden field:
Login form:
<input type="hidden" name="form_type" value="login" />
Register form:
<input type="hidden" name="form_type" value="register" />
Now, create a middleware that will process this new form element and flash the value to the session.
class FlashFormType
{
public function handle($request, Closure $next)
{
$response = $next($request);
if ($request->has('form_type')) {
$request->session()->flash('form_type', $request->input('form_type'));
}
return $response;
}
}
From here, you can either add this middleware to the web middleware group in app/Http/Kernel.php so it is used for all web requests, or you could just add this middleware to the LoginController and RegisterController constructors so that only they use it.
Once you've assigned the middleware somewhere, update your HomeController to access your flashed data:
class HomeController extends Controller
{
public function index(Request $request)
{
$form = $request->session()->get('form_type');
// the rest of your logic
}
}
NB: none of the provided code is tested. treat as pseudo-code.

Answer 2

If you want to get current user, that was authenticated with your login data, then \Auth:user() will go the trick. Here is index() of HomeController:
public function index()
{
return \Auth::user();
}
If you really need input data (actually I cannot imagine the case) , a solution may be to put request->all() in session session(['login_data' => $request->all() ]) and then retrieve it via session('login_data'). If you go that way, add this method to your LoginController:
/**
* Send the response after the user was authenticated.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
protected function sendLoginResponse(Request $request)
{
$request->session()->regenerate();
$this->clearLoginAttempts($request);
session(['login_data' => $request->all() ]);
return $this->authenticated($request, $this->guard()->user())
?: redirect()->intended($this->redirectPath());
}
This overrides original sendLoginResponse() method of AuthenticatesUsers trait. Then in HomeController put this:
public function index()
{
return session('login_data');
}
Hope this helps!
