How to Create Multi Auth in Laravel 5.2 - laravel-5

Question

I have made multi auth but i have problem with final code. I have code like this
php artisan make:auth
it will generate basic login/register route, view and controller for user table.
Make a admin table as users table for simplicity.
Controller For Admin
app/Http/Controllers/AdminAuth/AuthController
app/Http/Controllers/AdminAuth/PasswordController
(note: I just copied these files from app/Http/Controllers/Auth/AuthController here)
config/auth.php
//Authenticating guards
'guards' => [
'user' =>[
'driver' => 'session',
'provider' => 'user',
],
'admin' => [
'driver' => 'session',
'provider' => 'admin',
],
],
//User Providers
'providers' => [
'user' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
'admin' => [
'driver' => 'eloquent',
'model' => App\Admin::class,
]
],
//Resetting Password
'passwords' => [
'clients' => [
'provider' => 'client',
'email' => 'auth.emails.password',
'table' => 'password_resets',
'expire' => 60,
],
'admins' => [
'provider' => 'admin',
'email' => 'auth.emails.password',
'table' => 'password_resets',
'expire' => 60,
],
],
route.php
Route::group(['middleware' => ['web']], function () {
//Login Routes...
Route::get('/admin/login','AdminAuth\AuthController#showLoginForm');
Route::post('/admin/login','AdminAuth\AuthController#login');
Route::get('/admin/logout','AdminAuth\AuthController#logout');
// Registration Routes...
Route::get('admin/register', 'AdminAuth\AuthController#showRegistrationForm');
Route::post('admin/register', 'AdminAuth\AuthController#register');
Route::get('/admin', 'AdminController#index');
});
AdminAuth/AuthController.php
Add two methods and specify $redirectTo and $guard
protected $redirectTo = '/admin';
protected $guard = 'admin';
public function showLoginForm()
{
if (view()->exists('auth.authenticate')) {
return view('auth.authenticate');
}
return view('admin.auth.login');
}
public function showRegistrationForm()
{
return view('admin.auth.register');
}
it will help you to open another login form for admin
creating a middleware for admin
class RedirectIfNotAdmin
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #param string|null $guard
* #return mixed
*/
public function handle($request, Closure $next, $guard = 'admin')
{
if (!Auth::guard($guard)->check()) {
return redirect('/');
}
return $next($request);
}
}
register middleware in kernel.php
protected $routeMiddleware = [
'admin' => \App\Http\Middleware\RedirectIfNotAdmin::class,
];
use this middleware in AdminController e.g.,
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
class AdminController extends Controller
{
public function __construct(){
$this->middleware('admin');
}
public function index(){
return view('admin.dashboard');
}
}
And what does this code mean Auth::guard('admin')->user() ? And where must i type that code?

Answer 1

And what does this code mean Auth::guard('admin')->user() ?
In simple word, Auth::guard('admin')->user() is used when you need to get details of logged in user. But, in multi auth system, there can be two logged in users (admin/client). So you need to specify that which user you want to get. So by guard('admin'), you tell to get user from admin table.
Where must i type that code?
As from answer, you can understand that where must you use it. But still I can explain with example. Suppose there are multiple admins. Each can approve users request (like post/comments etc). So when an admin approve any request, then to insert id of that admin into approved_by column of post, you must use this line.
