BeforeFlexFormConfigurationOverrideEvent¶
New in version 12.3.
The PSR-14 event
\TYPO3\CMS\Extbase\Event\Configuration\BeforeFlexFormConfigurationOverrideEvent
can be used to implement a custom FlexForm override process
based on the original FlexForm configuration and the framework configuration.
Example¶
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Extbase\EventListener;
use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Extbase\Event\Configuration\BeforeFlexFormConfigurationOverrideEvent;
#[AsEventListener(
identifier: 'my-extension/before-flexform-configuration-override'
)]
final class MyEventListener
{
public function __invoke(BeforeFlexFormConfigurationOverrideEvent $event): void
{
// Configuration from TypoScript
$frameworkConfiguration = $event->getFrameworkConfiguration();
// Configuration from FlexForm
$originalFlexFormConfiguration = $event->getOriginalFlexFormConfiguration();
// Currently merged configuration
$flexFormConfiguration = $event->getFlexFormConfiguration();
// Implement custom logic
$flexFormConfiguration['settings']['foo'] = 'set from event listener';
$event->setFlexFormConfiguration($flexFormConfiguration);
}
}
New in version 13.0: The PHP attribute \TYPO3\CMS\Core\Attribute\AsEventListener
has been
introduced to tag a PHP class as an event listener. Alternatively, or if you
need to be compatible with older TYPO3 versions, you can also register an
event listener via the Configuration/Services.yaml
file. Switch to
an older version of this page for an example or have a look at the section
Implementing an event listener in your extension.
