Step 1 : Create Route

Here we are learning easy example of form validation in laravel 6. Open your routes/web.php and paste this following code.

routes/web.php

Route::get('storeuser', 'HomeController@create')->name('storeuser');
Route::post('storeuser', 'HomeController@store');

Step 2 : Create Controller:

Now we will add two controller method, one will just display blade file with get request, and another for post request, 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\User;
  
class HomeController extends Controller
{
    public function create()
    {
        return view('createUser');
    }
  
    public function store(Request $request)
    {
        $request->validate(
            [
                'name' => 'required',
                'password' => 'required|min:5',
                'email' => 'required|email|unique:users'
            ], 
            [
                'name.required' => 'Name is required',
                'password.required' => 'Password is required'
            ]
          );
   
        $input = $request->all();
        $input['password'] = bcrypt($input['password']);
        $user = User::create($input);
    
        return back()->with('success', 'User created successfully.');
    }
}
