Custom validation rule with request class not working laravel 7

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....

it is extends Illuminate\Foundation\Http\FormRequest; not Illuminate\Http\Request; — Alzafan Christian, Sep 07 '20 at 04:06
@AlzafanChristian This is working but I want to know that how can I return a custom response from the controller if validation fails and I got validation message even I both parameter inserting right. can you have idea for this? — Vishal Vaishnav, Sep 07 '20 at 04:30

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) :

I inserted both fields correct still validation gives message. I can't echo field – Vishal Vaishnav Sep 07 '20 at 04:45
replace your Request with normal Request from function, so you can dump the input fields – Alzafan Christian Sep 07 '20 at 04:47
or use this if you trying to using my code, in failedValidation() dd($validator->errors()->all()); – Alzafan Christian Sep 07 '20 at 04:49
I dont understand what you are saying. Actually I'm new in laravel. Can you write code in your answer. I want to return custome response like {"code":"404","message":"Name field is empty"}. – Vishal Vaishnav Sep 07 '20 at 04:49
you are not asking for it in your question. my answer edited – Alzafan Christian Sep 07 '20 at 05:02
if your request is not ajax, use $errors in your blade to see the message – Alzafan Christian Sep 07 '20 at 05:14
Actually I am not working with blade, I am developing the rest API for mobile development. and if I enter name and photo correct in form data still validator gives me error. I attached screenshot – – Vishal Vaishnav Sep 07 '20 at 05:21

use Illuminate\Foundation\Http\FormRequest;

class FruitRequest extends FormRequest
