    {{ method_field('PUT') }}

How to create a validator

Create custom request by running php artisan make:request UserRequest.

Open UserRequest.php located at app/Http/Requests.

Add validation rules for your form at rules() method:

return [
    'name' => 'required|min:6|max:255',
    'email' => 'required|email|max:255|unique:users',
    'password' => 'required|min:6|confirmed',
];

Next, include UserRequest namespace in UserController - use App\Http\Requests\UserRequest;.

Now in UserController's store(Request $request) method, replace store(Request $request) with store(UserRequest $request).

To display error message

Following are the sample to display an error message

@if ($errors->has('email'))
    <span class="help-block">
        <strong>{{ $errors->first('email') }}</strong>
    </span>
@endif

Authorization

You may return to true in UserRequest's authorize() method if there's no particular authorization required.

public function authorize()
{
    return true;
}

Validation from within Controller

$this->validate($request, [
    'name' => 'required|min:6|max:255',
    'password' => 'required|min:6|confirmed',
]);
