Question

在我的插件Model/Observer.php中，我有2个函数，它们对应于2个不同的事件，但我想将第一个函数的变量传递给下一个函数。我试过这样的事情：

class ContactologyProduct_LogProductUpdate_Model_Observer
{

(...)

public function beforeAddressSave(Varien_Event_Observer $observer) {

  $contactologyClientIdBeforeEdit = $this->getCustomerAddress();

  $this->setData('contactologyClientIdBeforeEdit', $contactologyClientIdBeforeEdit);  // won't work

}

public function afterAddressSave(Varien_Event_Observer $observer) {

  $contactologyClientIdAfterEdit = $this->getCustomerAddress();

  $contactologyClientIdBeforeEdit = $this->getData('contactologyClientIdBeforeEdit');  // won't work

  var_dump($contactologyClientIdBeforeEdit); // won't work
  var_dump($contactologyClientIdAfterEdit);

}

}

但setData()无法正常工作，我收到错误：

Call to a member function setData() on a non-object

在$contactologyClientIdBeforeEdit函数中保存beforeAddressSave()的方法是正确的，以便稍后可以在afterAddressSave()中访问它？

Answer 1

public function beforeAddressSave(Varien_Event_Observer $observer) {
   $contactologyClientIdBeforeEdit = $this->getCustomerAddress();
   $this->setData('contactologyClientIdBeforeEdit', $contactologyClientIdBeforeEdit);  // won't work
}

你应该使用$ observer而不是$ this，但是你应该看看事件的创建地点，因为你可以有类似的东西：

$contactologyClientIdBeforeEdit = $observer->getEvent()->getCustomerAddress();

然后，您可以在类中实现setData和getData，或者让您的类扩展Varien_Object类。所以，我想你会有：

class ContactologyProduct_LogProductUpdate_Model_Observer extends Varien_Object {
public function beforeAddressSave(Varien_Event_Observer $observer) {
   $contactologyClientIdBeforeEdit = $observer->getCustomerAddress(); //or $observer->getEvent()->getCustomerAddress() look how the event data is set.
   $this->setData('contactologyClientIdBeforeEdit', $contactologyClientIdBeforeEdit);
}
public function afterAddressSave(Varien_Event_Observer $observer) {
   $contactologyClientIdAfterEdit = $observer->getCustomerAddress();
   $contactologyClientIdBeforeEdit = $this->getData('contactologyClientIdBeforeEdit');
}

如何在插件的Observer.php中传递函数？
