如何解决Shopware 6:如何通过SalesChannel级别的EventSubscriberInterface检测任何类别的添加/更新?
有人知道如何检查Shopware 6中是否在添加/更新/删除了特定类别吗?
我想通过 Subscriber 使用Symfony\Component\Eventdispatcher\EventSubscriberInterface
还是必须实现其他功能?
更新:能够找到几个与实体相关的事件,但仍无法区分(检测)类别是添加还是修改
plugin / src / Resources / config / services.xml
<!-- ... -->
<service id="MyPlugin\MySubscriber">
<tag name="kernel.event_subscriber"/>
</service>

MySubscriber.PHP
<?PHP declare(strict_types=1);
namespace MyPlugin;
use Symfony\Component\Eventdispatcher\EventSubscriberInterface;
use Shopware\Core\Content\Category\CategoryEvents;
use Shopware\Core\Content\Category\Event\CategoryIndexerEvent;
use Shopware\Core\Framework\DataAbstractionLayer\Event\EntityDeletedEvent;
use Shopware\Core\Framework\DataAbstractionLayer\Event\EntityWrittenEvent;
class MySubscriber implements EventSubscriberInterface
{
public static function getSubscribedEvents(): array
{
return [
CategoryEvents::CATEGORY_INDEXER_EVENT => 'onCategoryIndex',CategoryEvents::CATEGORY_DELETED_EVENT => 'onCategoryDelete',CategoryEvents::CATEGORY_WRITTEN_EVENT => 'onCategoryWritten'
];
}
public function onCategoryWritten(EntityWrittenEvent $event): void
{
$ids = $event->getIds();
//how to check here whether category is adding or modified here or any other event.
//EntityWrittenEvent in both actions(add/modify) this listener is triggering
file_put_contents('/var/onCategoryWritten.text',print_r($ids,true),FILE_APPEND | LOCK_EX);
}
public function onCategoryDelete(EntityDeletedEvent $event): void
{
$ids = $event->getIds();
file_put_contents('/var/onCategoryDelete.text',FILE_APPEND | LOCK_EX);
}
public function onCategoryIndex(CategoryIndexerEvent $event): void
{
$ids = $event->getIds();
file_put_contents('/var/onCategoryIndex.text',FILE_APPEND | LOCK_EX);
}
}
解决方法
您可以检查在写入结果中完成的操作,例如
foreach(event->getWriteResults() as $writeResult) {
if ($writeResult->getOperation() === EntityWriteResult::OPERATION_INSERT)
{
//entity created
}
if ($writeResult->getOperation() === EntityWriteResult::OPERATION_UPDATE)
{
//entity updated/modidfied
}
}
