Laravel 5 change request form failed validation

Question

I have a form request to validate my credentials. The application is a mobile API, and I would like this class to return formatted JSON in case of failed validation, and not what it does by default (redirection).

I tried to override the failedValidation method from Illuminate\Foundation\Http\FormRequest . but this does not seem to work. Any ideas?

code:

 <?php namespace App\Http\Requests; use App\Http\Requests\Request; use Illuminate\Contracts\Validation\Validator; class RegisterFormRequest extends Request { /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return TRUE; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { return [ 'email' => 'email|required|unique:users', 'password' => 'required|min:6', ]; } } 

Answer 1

Looking at the following function in Illuminate\Foundation\Http\FormRequest , it seems that Laravel handles it correctly.

  /** * Get the proper failed validation response for the request. * * @param array $errors * @return \Symfony\Component\HttpFoundation\Response */ public function response(array $errors) { if ($this->ajax() || $this->wantsJson()) { return new JsonResponse($errors, 422); } return $this->redirector->to($this->getRedirectUrl()) ->withInput($this->except($this->dontFlash)) ->withErrors($errors, $this->errorBag); } 

And according to the wantsJson function in Illuminate\Http\Request below, you should explicitly look for the JSON answer,

  /** * Determine if the current request is asking for JSON in return. * * @return bool */ public function wantsJson() { $acceptable = $this->getAcceptableContentTypes(); return isset($acceptable[0]) && $acceptable[0] == 'application/json'; }

There is no need to redefine any function. just add

 Accept: application/json 

In the header of the form. Laravel will return the response in the same URL and in JSON format.

This is my decision, and it works well at my end. I added the function below the request code:

 public function response(array $errors) { if ($this->ajax() || $this->wantsJson()) { return Response::json($errors); } return $this->redirector->to($this->getRedirectUrl()) ->withInput($this->except($this->dontFlash)) ->withErrors($errors, $this->errorBag); } 

The response function is well handled by laravel. It will automatically return if you request json or ajax.

Just add the following function to your query:

 use Response; public function response(array $errors) { return Response::json($errors); }
