Multi-Auth Auth::user() Showing null Laravel 5.8 - php

Question

I am implementing multiple authentication as I have 3 different user groups. I am trying the following steps.
LoginController.php
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Auth;
class LoginController extends Controller
{
use AuthenticatesUsers;
protected $redirectTo = '/home';
public function __construct()
{
$this->middleware('guest')->except('logout');
$this->middleware('guest:admin')->except('logout');
$this->middleware('guest:manager')->except('logout');
$this->middleware('guest:vendor')->except('logout');
}
public function showAdminLoginForm()
{
return view('auth.login', ['url' => 'admin']);
}
public function adminLogin(Request $request)
{
$this->validate($request, [
'email' => 'required|email',
'password' => 'required|min:6'
]);
if (Auth::guard('admin')->attempt(['email' => $request->email, 'password' => $request->password], $request->get('remember'))) {
return redirect()->intended('/admin');
}
return back()->withInput($request->only('email', 'remember'));
}
public function showManagerLoginForm()
{
return view('auth.login', ['url' => 'manager']);
}
public function managerLogin(Request $request)
{
$this->validate($request, [
'email' => 'required|email',
'password' => 'required|min:6'
]);
if (Auth::guard('manager')->attempt(['email' => $request->email, 'password' => $request->password], $request->get('remember'))) {
return redirect()->intended('/manager');
}
return back()->withInput($request->only('email', 'remember'));
}
public function showVendorLoginForm()
{
return view('auth.login', ['url' => 'vendor']);
}
public function vendorLogin(Request $request)
{
$this->validate($request, [
'email' => 'required|email',
'password' => 'required|min:6'
]);
if (Auth::guard('vendor')->attempt(['email' => $request->email, 'password' => $request->password], $request->get('remember'))) {
return redirect()->intended('/vendor');
}
return back()->withInput($request->only('email', 'remember'));
}
}
AdminController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Auth;
class AdminController extends Controller
{
public function __construct()
{
$this->middleware('guest:admin');
}
public function dashboard()
{
dd(auth()->user());
return view('admin');
}
}
ManagerController and VendorController are same As AdminController.
Web.php
Route::view('/', 'welcome');
Auth::routes();
Route::prefix('admin')->group(function () {
Route::get('/login', 'Auth\LoginController#showAdminLoginForm');
Route::post('/login', 'Auth\LoginController#adminLogin');
Route::get('/register', 'Auth\RegisterController#showAdminRegisterForm');
Route::post('/register', 'Auth\RegisterController#createAdmin');
});
Route::prefix('manager')->group(function () {
Route::get('/login', 'Auth\LoginController#showManagerLoginForm');
Route::post('/login', 'Auth\LoginController#managerLogin');
Route::get('/register', 'Auth\RegisterController#showManagerRegisterForm');
Route::post('/register', 'Auth\RegisterController#createManager');
});
Route::prefix('vendor')->group(function () {
Route::get('/login', 'Auth\LoginController#showVendorLoginForm');
Route::post('/login', 'Auth\LoginController#vendorLogin');
Route::get('/register', 'Auth\RegisterController#showVendorRegisterForm');
Route::post('/register', 'Auth\RegisterController#createVendor');
});
Route::view('/home', 'home')->middleware('auth');
Route::get('/admin', 'AdminController#dashboard');
Route::get('/manager', 'ManagerController#dashboard');
Route::get('/vendor', 'VendorController#dashboard');
RedirectIfAuthenticated.php
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Auth;
class RedirectIfAuthenticated
{
public function handle($request, Closure $next, $guard = null)
{
if ($guard == "admin" && Auth::guard($guard)->check()) {
return redirect('/admin');
}
if ($guard == "manager" && Auth::guard($guard)->check()) {
return redirect('/manager');
}
if ($guard == "vendor" && Auth::guard($guard)->check()) {
return redirect('/vendor');
}
if (Auth::guard($guard)->check()) {
return redirect('/home');
}
return $next($request);
}
}
config.auth.php
<?php
return [
'defaults' => [
'guard' => 'admin',
'passwords' => 'admins',
],
'guards' => [
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
'manager' => [
'driver' => 'session',
'provider' => 'managers',
],
'vendor' => [
'driver' => 'session',
'provider' => 'vendors',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
'hash' => false,
],
],
'providers' => [
'admins' => [
'driver' => 'eloquent',
'model' => App\Admin::class,
],
'managers' => [
'driver' => 'eloquent',
'model' => App\Manager::class,
],
'vendors' => [
'driver' => 'eloquent',
'model' => App\Vendor::class,
],
],
'passwords' => [
'admins' => [
'provider' => 'admins',
'table' => 'password_resets',
'expire' => 60,
],
'managers' => [
'provider' => 'managers',
'table' => 'password_resets',
'expire' => 60,
],
'vendors' => [
'provider' => 'vendors',
'table' => 'password_resets',
'expire' => 60,
],
],
];
When I am trying to get the Auth::user() by doing dd() at AdminController, it shows me null because of multi-auth. Though it logged in successfully. I assume I am not using proper guard for the admin. But at the same time I have no clue how to fix this. Please help me out.

Answer 1

In multi authentications:
We can access authenticated user directly using Auth::user(). It will return the authentication by default guard = 'users'.
For other authentication, we should user guard('guard_name').
In your case, you should use Auth::guard('admins')->user() instead of Auth::user().

Answer 2

Everything seems alright. But you have missed adding web middleware for routes.
Please edit your web.php like this and it will work.
Route::group(['middleware' => ['web']], function () {
// all your routes use Auth() besides login route should be encapsulated and go inside this.
});
it is because web middleware has session class, check-in app.Http/kernel.php
\Illuminate\Session\Middleware\StartSession::class,
