Php Shopware6：订单付款时，订阅哪个事件？

我想知道如果我想在客户创建订单后，支付订单时触发功能，我应该使用哪个事件

我已经试过了：state\u enter.order\u transaction.state.paid=>“onordercechkout”

不幸的是，它给出了一个错误： 警告：使用未定义的常量状态输入-假定为“状态输入”（这将在 PHP的未来版本）*”

这是我的订户：

namespace Emakers\TransmissionPlugin\Subscriber;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Shopware\Core\Framework\DataAbstractionLayer\Event\EntityLoadedEvent;
use Symfony\Component\HttpKernel\Event\ExceptionEvent;
use Shopware\Core\Checkout\Order\OrderEntity;
use Shopware\Core\Checkout\Order\OrderEvents;
use Shopware\Core\System\StateMachine\Event;
use Shopware\Core\Framework\Event\EventData\EntityType;
use Shopware\Core\System\SystemConfig\SystemConfigService;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Criteria;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Filter\EqualsFilter;
use Emakers\TransmissionPlugin\Services\ShopwareConnectService;


class OrderSubscriber implements EventSubscriberInterface
{
    /**
     * @ContainerInterface $container
     */
    private $container;


     /**
     * @var datetime
     */
     private $now;


     public function __construct(ContainerInterface $container) {
                $this->container = $container;
                $this->now = date('Y-m-d H:i:s');
     }

    public static function getSubscribedEvents(): array
    {
        return [
                'state_enter.order_transaction.state.paid'   => 'onOrderCheckout',
        ];
    }
        public function orOrderCheckout($event)
        {
                var_dump($event);
                die('here we are');
        }
}

我使用StateMachineTransitionEvent进行此操作。使用Shopware 6.2进行测试

<?php declare(strict_types=1);

namespace Your\Namespace;

use Shopware\Core\Checkout\Order\Aggregate\OrderTransaction\OrderTransactionDefinition;
use Shopware\Core\Checkout\Order\Aggregate\OrderTransaction\OrderTransactionStates;
use Shopware\Core\Checkout\Order\OrderEntity;
use Shopware\Core\Framework\Context;
use Shopware\Core\Framework\DataAbstractionLayer\EntityRepositoryInterface;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Criteria;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Filter\EqualsFilter;
use Shopware\Core\System\StateMachine\Event\StateMachineTransitionEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class OrderStateSubscriber implements EventSubscriberInterface {

    /**
     * @var EntityRepositoryInterface
     */
    private $stateMachineStateRepository;

    /**
     * @var EntityRepositoryInterface
     */
    private $orderRepository;

    public function __construct(EntityRepositoryInterface $stateMachineStateRepository, EntityRepositoryInterface $orderRepository)
    {
        $this->stateMachineStateRepository = $stateMachineStateRepository;
        $this->orderRepository = $orderRepository;
    }

    public static function getSubscribedEvents(): array
    {
        return [
            StateMachineTransitionEvent::class => 'onStateTransition'
        ];
    }

    public function onStateTransition(StateMachineTransitionEvent $event) {
        // Since you are only interested in order transitions
        if ($event->getEntityName() !== OrderTransactionDefinition::ENTITY_NAME) {
            return;
        }

        $orderTransactionsStatePaidId = $this->getOrderTransactionsStatePaidId($event->getContext());
        if ($orderTransactionsStatePaidId === null) {
            return;
        }

        // Check if it was transitioned to paid
        if ($event->getToPlace()->getId() !== $orderTransactionsStatePaidId) {
            return;
        }

        // Transaction was changed to paid do your thing
        $order = $this->getOrder($event->getEntityId(), $event->getContext());
    }

    private function getOrderTransactionsStatePaidId(Context $context): ?string {
        $criteria = new Criteria();
        // Add filter for OrderTransactionStateMachine
        $criteria->addFilter(
            new EqualsFilter('stateMachine.technicalName', \sprintf('%s.state', OrderTransactionDefinition::ENTITY_NAME)),
            new EqualsFilter('technicalName', OrderTransactionStates::STATE_PAID)
        );

        return $this->stateMachineStateRepository->searchIds($criteria, $context)->firstId();
    }
    
    private function getOrder(string $orderTransactionId, Context $context): ?OrderEntity
    {
        $criteria = new Criteria();
        $criteria->addFilter(
            new EqualsFilter('transactions.id', $orderTransactionId)
        );
        
        return $this->orderRepository->search($criteria, $context)->first();
    }
}

在名称周围加引号，它已经是正确的：'state\u enter.order\u transaction.state.paid'（在本例中它不是一个PHP常量，而是一个简单的字符串）@Susi我加了引号，但不幸的是，当我下订单并直接付款时，它没有触发ordercheckout（）函数。我更新了我的帖子以添加订户的内容，这可能有助于了解问题所在。@UmarZahid我添加了一个示例services.xml条目。谢谢您的回复。我是在问你之后发现的：’）最后一个问题：我需要获得已付款订单的信息，但在倾销$event时。我没有任何orderId或其他东西。在这种情况下有可能得到它们吗？如果我只有orderId，我很高兴你有了属性entityId。这是OrderTransactionId，您可以使用它获取订单，因为它们有直接关联。很抱歉，我现在无法测试，我必须等待同事支付测试费用。但这会是这样的吗？：
$entityId=$event->getEntityId（）；/*@var EntityRepositoryInterface$orderRepository*/$orderRepository=$this->container->get（'order.repository'）$orderInfo=$orderRepository->SearchID（（新标准（））->addFilter（新的EqualFilter（'orderTransactionId'，$entityId）），\Shopware\Core\Framework\Context:：createDefaultContext（））->GetID（）[0]我调整了我的答案，这样你就可以下订单了。
