how to use a laravel method in a request

  • 772

How can I do this validation within the request class, this part corresponds to a controller method

public function store(vendedorrequest $request)
    {
        $validator = \Validator::make($request->all(), [
            'nombre' => 'required',
            'nombre.required'=>'Rellena el campo nombre',
        ]);

        if ($validator->fails()) {
            return response()->json($validator->errors(), 422);
       }

    }

this is the request where I want to apply the make method, but I only know how to do it directly from the controller

  public function rules()
    {

        return  [
            'documento'=>'required|numeric|unique:vendedores,documento',
            'correo'=>'required|email|unique:vendedores,correo',
            'nombre'=>'required',
            'direccion'=>'required',
        ];
    }

    Validation in Form Request

    Create a FormRequest

    Form requests are custom request classes that contain validation logic. To create a form request class, use the CLI Artisan command make:request:

    php artisan make:request StoreVendedor

    The generated class will be located in the app/Http/Requests. If this directory does not exist, it will be created when you run the command make:request. Add the validation rules to the method rules:

    / **
 * Obtenga las reglas de validación que se aplican al requst.
 * *
 * @return array
 * /
public function rules()
{
    return [
        'documento'=>'required|numeric|unique:vendedores,documento',
        'correo'=>'required|email|unique:vendedores,correo',
        'nombre'=>'required',
        'direccion'=>'required',
    ];
}

    So how are validation rules evaluated? All you need to do is inject the request into your controller method. The incoming form request is validated before the controller method is called:

    / **
 * Almacene los datos del Vendedor en la Base de Datos.
 * *
 * @param  StoreVendedor  $request
 * @return Response
 * /
public function store(StoreVendedor $request)
{
    // El request entrante es válido ...

    // Obtén los datos de entrada validados ...
    $validated = $request->validated();

    // haz algo aquí con los datos validados ...
}

    If validation fails, a redirect response will be generated to send the user back to their previous location. The errors will also be displayed in the session so that they are available for viewing. If the request was an AJAX request, an HTTP response with a 422 status code will be returned to the user, including a JSON representation of any validation errors.

    You can override the method failedValidationif you want to customize the response:

    protected function failedValidation(Validator $validator) {

    throw new HttpResponseException(response()->json($validator->errors(), 422));

}

    Note that you will have to import those classes in the form requirements in order to use them by adding these lines above:

    use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Exceptions\HttpResponseException;
