# Breaking: #109811 - Removed "afterFormStateInitialized" hook

See [forge#109811](https://forge.typo3.org/issues/109811)

## Description

The hook
`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['ext/form']['afterFormStateInitialized']`
has been removed in favor of the PSR-14 event
`\TYPO3\CMS\Form\Event\AfterFormStateInitializedEvent`.

In addition, the interface
`\TYPO3\CMS\Form\Domain\Runtime\FormRuntime\Lifecycle\AfterFormStateInitializedInterface`
has been removed as it was only used by the hook.

## Impact

Hook implementations registered under `afterFormStateInitialized` are
no longer executed in TYPO3 v15.0 and later.

Classes implementing
`\TYPO3\CMS\Form\Domain\Runtime\FormRuntime\Lifecycle\AfterFormStateInitializedInterface`
will cause a PHP fatal error.

## Affected installations

TYPO3 installations with custom extensions using this hook or implementing
`AfterFormStateInitializedInterface` are affected.

The extension scanner reports any usage as a strong match.

## Migration

Register a PSR-14 event listener for
`\TYPO3\CMS\Form\Event\AfterFormStateInitializedEvent` instead:

**EXT:my_extension/Classes/EventListener/MyAfterFormStateInitializedEventListener.php**

```php
use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Form\Event\AfterFormStateInitializedEvent;

#[AsEventListener(identifier: 'my-extension/after-form-state-initialized')]
final readonly class MyAfterFormStateInitializedEventListener
{
    public function __invoke(AfterFormStateInitializedEvent $event): void
    {
        // Access $event->formRuntime->getFormState() here
    }
}
```

Remove the hook registration from `ext_localconf.php` and the
`AfterFormStateInitializedInterface` implementation from your hook class.
