Laravel：自定义表单请求中的自定义验证消息

Question

I am trying to keep my controller clean and move the custom request validation in to a separate class as:

public function register(RegisterUserRequest $request)

and in there define all the usual functions, such as

public function rules(),
public function messages(), and
public function authorize()

However, the frontend is expecting the following data to display: title (title related to the validation error message), description (which is the the actual validation error message), and status (=red, yellow etc)

How can I actually customise the response of the request?

Something like this, does not seem to be working:

protected function  failedValidation(\Illuminate\Contracts\Validation\Validator $validator)
        {
            $response = new Response(['data' => [],
                'meta' => [
                    'title' => 'Email Invalid'
                    'description' => '(The error message as being returned right now)',
                    'status' => 'red'
                ]);

            throw new ValidationException($validator, $response);

    }

Any ideas?

Answer 1

you can do this by making request in laravel as the following :

php artisan make:request FailedValidationRequest

this command will create class called FailedValidationRequest in

App\\Http\\Request directory and you cab write your rules inside this class as the following:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class FailedValidationRequest extends FormRequest
{
/**
 * 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 [
       'title' => 'required'
       'description' => 'required',
       'status' => 'required|numeric'
    ];
}

}

and if you want to customize the error message you can download the language you want from this link using composer: https://packagist.org/packages/caouecs/laravel-lang

and write the language you want by copying the languge folwder to the lang directory in your resource folder.

'custom' => [
    'title' => [
        'required' => 'your custom message goes here',
    ],
 'decription' => [
        'required' => 'your custom message goes here',
    ],
   ],
