在通过 Laravgel API 使用请求验证 class 时，对 Z37A62786688DAFFD29 上的成员 functionvalidated() 的错误调用

Question

I am using Laravel Request validation class to validate input through API Reference

I implemented as it is mentioned in documentation and got the following error:

Symfony\Component\Debug\Exception\FatalThrowableError: Call to a member function validated() on null

The only difference I feel that they submit a form from a web and I am making a request from postman.

It's been a couple of hours, no clue yet. any help, please?

use Illuminate\Foundation\Http\FormRequest;

class UserTypeRequest extends FormRequest
{        
  public function authorize()
  {
    return true;
  }

  public function rules()
  {
            return [
                'user_type' => 'required',
            ];
        }
    }

Calling validation in controller:

$this->user_type_request = new UserTypeRequest();
$this->user_type_request->validated();

It should be validation input filed coming from the api, instead its showing null in lavatorial

Answer 1

Try and pass the form request via Dependancy injection:

public function store(UserTypeRequest $request)
{
    $var = $request->validated();

    ...
}

Creating a new form request probably is not validating the previous request (or getting the validation response from the previous request).

Answer 2

You don't need to call the validate function if you're passing the Form Request class in the controller function, just proceed and your request is automatically validated

public function controllerMethod(\App\Http\Requests\UserTypeRequest $request) // Just pass it here
{
  // Data is already checked
  $data = $request->validated();
}

Hope this helps
