Feature: #101396 - Let Extbase handle native enums¶

Description¶

With PHP 8.1, native support for enums has been introduced. This is quite handy if a database field has a specific set of values which can be represented by a PHP enum.

It is now possible to use backed enums in entities like this:

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Domain\Model\Enum;

enum Level: string
{
    case INFO = 'info';
    case ERROR = 'error';
}

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Domain\Model;

use TYPO3\CMS\Extbase\DomainObject\AbstractEntity;

class LogEntry extends AbstractEntity
{
    protected Enum\Level $level;
}

Impact¶

To implement enums, it is no longer necessary to extend the now deprecated TYPO3 Core class \TYPO3\CMS\Core\Type\Enumeration.
