Symfony-是否可以将实体设置为全局？

如何解决Symfony-是否可以将实体设置为全局？

我有一个在登录页面上扩展的实体，但在下一页上，扩展名不存在（实体在两个页面上都存在）。有没有办法在下一页上提供我的扩展程序？

<?PHP
namespace RegistrationExtension\Subscriber;

use ...

class RegisterExtensionSubscriber implements EventSubscriberInterface{
    private $company;

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

    /**
     * @var EntityRepositoryInterface
     */
    private $mailRepository;
    /**
     * @var EntityRepositoryInterface
     */
    private $customerRepo;

    public function __construct(
        EntityRepositoryInterface $customerRepo,EntityRepositoryInterface $mailTypeRepository,EntityRepositoryInterface $mailRepository
    ) {
        $this->customerRepo = $customerRepo;
         $this->mailTypeRepository = $mailTypeRepository;
         $this->mailRepository = $mailRepository;
    }
    public static function getSubscribedEvents(): array{
        return [
            AccountLoginPageLoadedEvent::class => 'extendCustomer',AccountOverviewPageLoadedEvent::class => 'onCustomregister'
        ];
    }

此功能在登录页面完成加载时触发。

    public function extendCustomer(AccountLoginPageLoadedEvent $event){
       // if (isset($_POST['submit'])) {
            if(isset($_GET["email"])){
                $company = $_GET["email"];
            }else{
                $company = null;
            }
            $mailEntity = $this->mailTypeRepository->search(
                (new Criteria())->addFilter(new EqualsFilter('mail_template_type.technicalName',"customer_register")),$event->getContext()
            );
    
            if ($mailType = $mailEntity->getEntities()->first()) {
                $mailEntity = $this->mailRepository->search(
                    (new Criteria())->addFilter(new EqualsFilter('mail_template.mailTemplateTypeId',$mailType->getId())),$event->getContext()
                );
            
                $mailEntity->getEntities()->first()->addExtension('file_does_exist',new ArrayEntity(['company' => "blub"]));
                dump($mailEntity->getEntities()->first());
            }
       // }
    }

此功能在用户登录并完成页面加载后触发。

    public function onCustomregister(AccountOverviewPageLoadedEvent $event){
        $mailEntity = $this->mailTypeRepository->search(
            (new Criteria())->addFilter(new EqualsFilter('mail_template_type.technicalName',$event->getContext()
        );

        if ($mailType = $mailEntity->getEntities()->first()) {
            $mailEntity = $this->mailRepository->search(
                (new Criteria())->addFilter(new EqualsFilter('mail_template.mailTemplateTypeId',$event->getContext()
            );
            dump($mailEntity);
          //  $mail = $mailEntity->getEntities()->first()->addExtension('file_does_exist',new ArrayEntity(['company' => $company]));
        }
        $customerEntity = $this->customerRepo->search(
            (new Criteria())->addFilter(new EqualsFilter('customer.customerNumber',$event->getSalesChannelContext()->getCustomer()->getCustomerNumber())),$event->getContext()
        );         
    }
}

是否可以将AccountOverviewPageLoadedEvent事件载入？

解决方法

正如您在开发时已经发现的那样，扩展不会持久存在。 您想要的是EntityExtension。这样，您可以扩展客户实体。但是，由于只能通过EntityExtension添加关联和外键字段，因此您将需要一个自己的实体。

因此，假设您create a entity：CustomerRegistrationFile 然后，您可以扩展CustomerDefinition并将您的CustomerRegistrationFile添加为关联。这样，您可以直接在实体上保留数据，并可以将其加载到任何需要的位置，例如在邮件模板中。

侧面说明：关联不会自动加载。除了OneToOneAssociations，可以从一端自动加载。为了防止循环引用，不是两端都没有。
