Laravel Nullable is not working, i try everything but it still not working. Please Look My Code..

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Pop;

class PopController extends Controller
{
    public function index(){
        return view('test2');
    }

    {
        Schema::create('pops', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->integer('usercode')->nullable();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('pops');
    }
}

Route :- 


route::get('test', 'PopController@index');

route::post('testcheck', 'PopController@create')->name('uc');

View :- 


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Nullable Test</title>
</head>
<body>
    <h1>Test Nullable</h1>
    <form action="{{ route('uc') }}" method="POST">
        @csrf

        <input type="number" name="usercode" id="" placeholder="Enter User Code">
            @error('usercode')
                {{ $message }}
            @enderror
        <br>
        <input type="submit" >

    </form>
</body>
</html>

It's not right to use nullable and required validations rules together:

  • required: The field under validation must be present in the input data and not empty.
  • nullable: The field under validation may be null.
  • present: The field under validation must be present in the input data but can be empty.
  • filled: The field under validation must not be empty when it is present.
  • prohibited: The field under validation must be empty or not present.
  • sometimes: The field under validation will only be validated if it is present.
  • exclude: The field under validation will be excluded from the request data returned by the validate and validated methods.

You may use nullable and present together:

$formvalidtion = $request->validate([
    'usercode' => ['nullable', 'present'],
]);

You don't specify what you mean with "not working" (i.e. what you expect, but what happens instead), but I'm assuming you mean that null values are not accepted by the validation.

That would be because the required rule expects a value to be non-empty. So your nullable rule probably passes, but required fails.

If you want a value to be present, but not necessarily non-empty, you can use the present rule.
