 <?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

//tambahan
use Illuminate\Auth\Events\Registered;
use Illuminate\Http\Request;
use App\Mail\userRegistered;
use Illuminate\Support\Facades\Mail;

class RegisterController extends Controller
{

    use RegistersUsers;

    protected $redirectTo = '/home';

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

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }

    public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

        return redirect('/login');
    }

    protected function create(array $data)
    {
        $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'token' => str_random(40)
        ]);

        //mengirim email
        Mail::to($user->email)->send(new userRegristered($user));
    }
}
