Add status flag to Laravel validation response - laravel

Question

How can I add the status flag to Laravel (6.0) validation response?
this is my validation class.
class LoginRequest extends FormRequest{
public function authorize()
{
return true;
}
public function rules()
{
return [
'email' => 'required|email|exists:users,email',
'password' => 'required|min:4|max:8'
];
}
}
according to the above validation following response is a return
{
"message": "The given data was invalid.",
"errors": {
"email": [
"The selected email is invalid."
]
}
}
but I need reformat above response like this.
{
"status": "fail",
"message": "The given data was invalid.",
"errors": {
"email": [
"The selected email is invalid."
]
}
}

Answer 1

All you need, create your response method and override failedValidation. Clear?
Update
In LoginRequest
protected function failedValidation(Validator $validator)
{
$this->currentValidator = $validator;
throw new ValidationException($validator, $this->errorResponse(
$this->formatErrors($validator)
));
}
protected function errorResponse(array $errors)
{
//something else
return response($errors);
}
Please look up Illuminate\Validation\ValidationException

Answer 2

Create a custom exception.
php artisan make:exception MyCustomException
Then, override the failedValidation method from FormRequest class
use Illuminate\Contracts\Validation\Validator;
use App\Exceptions\MyCustomException;
class LoginRequest extends FormRequest
{
public function authorize()
{
return true;
}
public function rules()
{
return [
'email' => 'required|email|exists:users,email',
'password' => 'required|min:4|max:8'
];
}
/**
* Handle a failed validation attempt.
*
* #param \Illuminate\Contracts\Validation\Validator $validator
*
* #return void
*
* #throws \App\Exceptions\MyCustomException
*/
protected function failedValidation(Validator $validator)
{
throw (new MyCustomException($validator));
}
}
and handle the response in App\Exceptions\MyCustomException class
<?php
namespace App\Exceptions;
use Exception;
use Symfony\Component\HttpFoundation\Response;
class MyCustomException extends Exception
{
/**
* The validator instance.
*
* #var \Illuminate\Contracts\Validation\Validator
*/
public $validator;
/**
* Create a new exception instance.
*
* #param \Illuminate\Contracts\Validation\Validator $validator
* #return void
*/
public function __construct($validator)
{
parent::__construct('The given data was invalid.');
$this->validator = $validator;
}
/**
* Get all of the validation error messages.
*
* #return array
*/
public function errors()
{
return $this->validator->errors()->messages();
}
/**
* Report the exception.
*
* #return void
*/
public function report()
{
//
}
/**
* Render the exception into an HTTP response.
*
* #param \Illuminate\Http\Request
* #return \Illuminate\Http\Response
*/
public function render($request)
{
if ($request->acceptsJson()) {
$errors = [
'status' => false,
'message' => 'The given data was invalid',
'errors' => $this->errors(),
];
return response()->json($errors, Response::HTTP_UNPROCESSABLE_ENTITY);
}
}
}
