Step 1 : Create Routes

Do you know Laravel has changed routing system. I am coming with a new tutorial about routing system in laravel. Have a look on new routing system in laravel. In this example we are learning simple and easy example of validation in laravel 8 so just add following both route in your web.php file.

routes/web.php

use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\HomeController;
  
Route::get('user/create', [ HomeController::class, 'create' ]);
Route::post('user/create', [ HomeController::class, 'store' ]);

Step 2 : Create Controller

Now we will add two controller method which we did write in web.php file, one will just display blade file with get request, and another for post request to save data into database, i write validation for that, so simply add both following method on it.

app/Http/Controllers/HomeController.php

namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\User;
  
class HomeController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('test');
    }
    
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $validatedData = $request->validate([
                'name' => 'required',
                'password' => 'required|min:5',
                'email' => 'required|email|unique:users'
            ], [
                'name.required' => 'Name is required',
                'password.required' => 'Password is required'
            ]);
  
        $validatedData['password'] = bcrypt($validatedData['password']);
        $user = User::create($validatedData);
      
        return back()->with('success', 'User created successfully.');
    }
}
