Craft Data

Automatically convert POST data over to strongly typed data objects. Attaching an attribute to your controller method is all it takes to do the conversion.

class EntryController extends Controller
{
    #[BodyParams(EntryUpdateParams::class)]
    function actionUpdate()
    {
        // Now $this->getData() will return an `EntryUpdateParams` with all the
        // data copied over from the POST in to the class
    }
}

The data object uses public properties and PHP type hints to map everything. See markhuot/data for more detail on mapping.

class EntryUpdateParams
{
    public int $elementId;
    public ?string $title;
    public ?string $slug;

    function getElement()
    {
        return \Craft::$app->elements->getElementById($this->elementId);
    }
}

All validation rules fromm markhuot/data work as well so you can ensure specific fields match the validation rules you expect.

use Symfony\Component\Validator\Constraints as Assert;

class EntryUpdateParams
{
    #[Assert\NotNull]
    public int $elementId;

    #[Assert\NotEmpty]
    public string $title;

    #[Assert\Regex('/[a-z]0-9_-/i')]
    public ?string $slug;

    function getElement()
    {
        return \Craft::$app->elements->getElementById($this->elementId);
    }
}
