History / Migration

The event TYPO3\CMS\Backend\Controller\Event\ModifyPageLayoutContentEvent has been introduced to serve as a more powerful and flexible alternative for the removed hooks $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/db_layout.php']['drawHeaderHook'] and $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/db_layout.php']['drawFooterHook'].

In contrast to the removed hooks, this event does not provide the PageLayoutController as $parentObject, since getModuleTemplate() has been the only public method, which is now directly included in the event.

Additionally, there were three public properties $id, $pageInfo and $MOD_SETTINGS, which had been marked as @internal in TYPO3 v9. If needed, the information can be retrieved from the request directly.

An example to get the current $id:

public function __invoke(ModifyPageLayoutContentEvent $event): void
{
    $id = (int)($event->getRequest()->getQueryParams()['id'] ?? 0);
}
