Create middleware to auth admin users

1- run :

php artisan make:middleware IsAdmin

2- Add it to the routeMiddleware array in your kernel file by opening app/Http/Kernel.php

'admin' => \App\Http\Middleware\IsAdmin::class,

3- Edit isAdmin file:

public function handle($request, Closure $next)
{
     if (Auth::user() &&  Auth::user()->admin == 1) {
            return $next($request);
     }

    return redirect('/');
}

4- Apply the middleware to your route:

Route::get('admin_area', ['middleware' => 'admin', function () {
    //
}]);

somewhat like Rachid ... check my ref to documentation at the end : In routes.php:

Route::group(['middleware' => 'isAdmin'], function () {
    Route::get('admin', 'adminController@adminDashboard');
});

In a middleware you create with artisan :

public function handle($request, Closure $next)
{
    // Obtenir la liste des roles de l'utilisateur
    $UserRoles = DB::table('roles')->join('role_user','role_id', '=', 'roles.id')->where('user_id', '=', Auth::user()->id)->lists('name');
    // vérifier si cet utilisateur  a le role d'admin
    $isAdmin = false;
    foreach($UserRoles as $role)
    {
        if($role == 'admin')
        {
            $isAdmin = true;
        }
    }

    // snippet ci-dessous selon doc de Laravel
    if( ! $isAdmin )
    {
        if ($request->ajax()) {
            return response('Unauthorized.', 401);
        } else {
            return redirect()->back(); //todo h peut-etre une fenetre modale pour dire acces refusé ici...
        }
    }

    return $next($request);

in kernel.php :

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'isAdmin' => \App\Http\Middleware\isAdmin::class,];

watch this :

and look at this :

Use the HomeController is a simple way

public function index() { $userId = \Auth::id();

    $user = User::find($userId);
    
    if($user->admin == 1)
    {
        return view('admin');
    }
    return view('home');
}

just need a table admin and a route and you have seperated users and admin.

in User model

public function isAdmin()

{

  if($this->status == 'Admin')
   return true;
  else
   return false;

}

create IsAdmin middleware

in middleware

public function handle($request, Closure $next) {

    if( ! $request->user()->isAdmin() )
    {
      return abort(404);
 //or redirect to somewhere
    }

    return $next($request);
}

add IsAdmin middleware class path to kernel too.

thank you :)

4- Or apply it to the controller if that controller is only for admin :).

Pay attention to the double auth here ;)

    public function __construct()
    {
        $this->middleware('auth');
        $this->middleware('admin');
    }
