您好我要按照此文档执行Symfony事件侦听器: http://symfony.com/doc/2.8/cookbook/doctrine/event_listeners_subscribers.html
<?php
namespace FM\AppBundle\EventListener;
use Doctrine\ORM\Event\LifecycleEventArgs;
use FM\AdminBundle\Entity\Address\BillingAddress;
class BillingAdressListener
{
/**
* @param LifecycleEventArgs $args
*/
public function listenBillingAdress(LifecycleEventArgs $args)
{
$entity = $args->getEntity();
if(!$entity instanceof BillingAddress){
return;
}
$this->postPersist($args);
}
/**
* @param LifecycleEventArgs $args
*/
public function postPersist(LifecycleEventArgs $args)
{
$em = $args->getEntityManager();
$billingAdress = $args->getEntity();
dump($billingAdress); die();
}
}
service.yml
billing_adress.listener:
class: FM\AppBundle\EventListener\BillingAdressListener
tags:
- { name: doctrine.event_listener, event: listenBillingAdress }
但是当我使用 BillingAddress 对象提交表单时,没有任何事情发生。
我做错了吗?

它在Doctrine中称为实体监听器。这是documentation。
不要忘记在映射中添加您的实体侦听器。例如xml映射:
<entity name="AppBundle\Entity\AssignmentAttempt" table="app_assignment_attempt" >
<entity-listeners>
<entity-listener class="AppBundle\EntityListener\AssignmentAttemptListener">
<lifecycle-callback type="prePersist" method="prePersist"/>
<lifecycle-callback type="preUpdate" method="preUpdate"/>
</entity-listener>
</entity-listeners>
<!-- Rest mapping -->
</entity>
在配置中,您只需添加
即可app.entity_listener.assignment_attempt:
class: AppBundle\EntityListener\AssignmentAttemptListener
tags:
- { name: doctrine.orm.entity_listener }

我的不好,我没有做坚持,而是更新。
适用于持久。
现在是我的代码:
<?php
namespace FM\AppBundle\EventListener;
use Doctrine\ORM\Event\LifecycleEventArgs;
use FM\AdminBundle\Entity\Address\BillingAddress;
class BillingAddressListener
{
/**
* @param LifecycleEventArgs $args
*/
public function prePersist(LifecycleEventArgs $args)
{
$entity = $args->getEntity();
if(!$entity instanceof BillingAddress){
return;
}
$this->addNameToUser($args);
}
/**
* @param LifecycleEventArgs $args
*/
public function addNameToUser(LifecycleEventArgs $args)
{
/** @var BillingAddress $billingAdress */
$billingAdress = $args->getEntity();
$user = $billingAdress->getOwner();
if(empty($user->getFirstName())) $user->setFirstName($billingAdress->getFirstName());
if(empty($user->getLastName())) $user->setLastName($billingAdress->getLastName());
}
}
我必须调用prePersist方法。 我正在做相反的事情。
billing_address.listener:
class: FM\AppBundle\EventListener\BillingAddressListener
tags:
- { name: doctrine.event_listener, event: prePersist }
