Below is my Data Transfer Object using Spatie\LaravelData\Data using Laravel Framework 9.52.16. In this definition $user_id is defined as optional property but yet when it is missing it throws an error.

<?php
namespace App\Http\DataTransferObjects\Listing;
use Spatie\LaravelData\Data;
use Spatie\LaravelData\Optional;

class ListingDTO extends Data
{
    public function __construct(public string $type, public string|Optional $user_id)
    {

    }
}

Exception

    "message": "App\\Http\\DataTransferObjects\\Listing\\ListingDTO::__construct(): Argument #2 ($user_id) not passed",
    "exception": "ArgumentCountError",
    ....

How can I define optional properties?

  • I'm not super-familiar with Laravel, but are you manually invoking the constructor, or is the framework. If it is you, I think you need to pass Optional::create() in order to make PHP happy. Commented Jul 1, 2024 at 18:35
  • I'm not sure where you got the string|Optional syntax from, but technically, you still need two arguments. I'd use string? $user_id = null in the declaration. Commented Jul 1, 2024 at 18:47
  • @UlrichEckhardt spatie.be/docs/laravel-data/v4/as-a-data-transfer-object/… it is in official documentation Commented Jul 1, 2024 at 18:49
  • Interesting. In any case, just arguing from the pure PHP side, your ctor takes two arguments. In the code where you try to create an instance, it does not provide a second parameter, which is why PHP at that point signals an error. Commented Jul 1, 2024 at 18:58

    public string|Optional $user_id = new Optional() ? Also, what version of LaravelData you're using? Commented Jul 1, 2024 at 19:02
