Custom validation rule with request class not working laravel 7 - php

Question

Below is my code;
FruitRequest.php
class FruitRequest extends Request
{
public function authorize()
{
return true;
}
public function rules()
{
return [
'name' => 'required|alpha',
'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048'
];
}
public function messages()
{
return ['name.required' => response("Name should be mandatory", 404),
'name.alpha' => response("Name should be contains only letters", 404),
'image.required' => response("Foto should be mandatory", 404),
'image.mimes' => response('Foto should be jpeg,png,jpg,gif,svg', 404),
'image.max' => response('Foto size should be blow 2 MB', 404),
];
}
}
FruitController.php
use App\Http\Controllers\Controller;
use App\Http\Requests\FruitRequest;
class FruitController extends Controller
{
public function store(FruitRequest $request)
{
echo $request->input('name');
//above line gives nothing to me
}
}
If I use extends Request instead of extends FruitRequest then this gives me value which is passed by user in postman. I don't know why this custom Request class not working.I attached screenshot. Please help....

Answer 1

extend your request class with FormRequest
use Illuminate\Foundation\Http\FormRequest;
class FruitRequest extends FormRequest
for more details visit official doc of laravel: https://laravel.com/docs/7.x/validation#creating-form-requests

Answer 2

long time not using postman, i'm testing with my code
I'm using FormRequest like this:
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Exceptions\HttpResponseException;
class YourRequest extends FormRequest
{
//this function called if Validator::make()->fails();
//here where you can modifying your message
protected function failedValidation(Validator $validator)
{
//note this only for API, for formData use \Illuminate\Validation\ValidationException($validator)
throw new HttpResponseException(response()->json($validator->errors()->all(), 422));
//this will get parameter attribute set from FormRequest
//attributes() along with the error message,
//or $validator->errors()->all() to get messages only like my screenshot
//or modify message with your logic
}
public function authorize() { return true; }
public function rules() { return []; }
public function attributes() { return []; }
public function messages() { return []; }
}
in controller :
use YourRequest;
public function store(YourRequest $req)
{
return response($req->all())->setStatusCode(200);
}
in your FormRequest replace response(), just text:
public function messages()
{
return ['name.required' => "Name should be mandatory"],
}
2nd, validation alpha only accepts alphabet, which your name is numeric,
result from my code(i use default validator message which in array of messages) :
