TYPO3和MySQL触发器

Question

In ext_tables.sql file of an extension I can define new tables/fields that are going to be added to the database.

Is it possible with TYPO3 to add also Triggers (MySQL) to database?

Answer 1

Not via ext_tables.sql .

You can use the extension manager signal slot and execute your queries there after installation of your extension

ext_localconf.php of your extension:

call_user_func(function($extensionKey) {
        $signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class);
        $signalSlotDispatcher->connect(
            \TYPO3\CMS\Extensionmanager\Service\ExtensionManagementService::class,
            'hasInstalledExtensions',
            function($keyOfInstalledExtension) use ($extensionKey) {
                if ($extensionKey !== $keyOfInstalledExtension) {
                    return;
                }
                \Vendor\MyExt\Hooks\ExtensionManager::postInstallExtension();
            }
        );
    }
}, $_EXTKEY);
