Step 4: Add Route

We need to create register routes as bellow:

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
 
use App\Http\Controllers\RegisterController;
  
Route::get('register', [RegisterController::class, 'index']);
Route::post('register', [RegisterController::class, 'store']);

Step 5: Create RegisterController

In this step, we have to create new controller as RegisterController and we have also need to add two methods index() and store() on that controller like as you can see bellow:

app/Http/Controllers/RegisterController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class RegisterController extends Controller
{
     /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function index()
    {
        return view('register');
    }
    
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function store(Request $request)
    {
        $this->validate($request, [
            'name' => 'required',
            'email' => 'required|email',
            'password' => 'required|same:password_confirmation',
            'password_confirmation' => 'required',
            'g-recaptcha-response' => 'required|recaptchav3:register,0.5'
        ]);
   
        dd('done');
    }
}

Step 6: Create View File

In Last step, let's create register.blade.php(resources/views/register.blade.php) for layout and lists all items code here and put following code:

resources/views/register.blade.php
