Magento - 無法保存更改的客戶GroupId觀察員爲newsletter_subscriber_save_before事件

Question

我建立了一個觀察員爲newsletter_subscriber_save_before event;當客戶訂閱/取消訂閱新聞通訊時，它會被解僱。 我需要相應地更改此客戶組ID。看來我可以更改GroupId，但我無法設法保存它。如果我在我的代碼中調用$customer->save() - 方法，我會遇到無限循環;如果我試圖鉤入newsletter_subscriber_save_after事件，也會發生同樣的情況。

任何人都可以幫到我嗎？將不勝感激！

這裏是我的代碼在Observer.php：

public function newsletter_subscriber_change($observer) { 
    try { 

     // get status of subscriber 
     $subscriber = $observer->getEvent()->getSubscriber(); 

     $status = $subscriber->getStatus(); 
     $email = $subscriber->getEmail(); 

     $customer = Mage::getSingleton('customer/customer'); 
     $customer->setWebsiteId(Mage::app()->getWebsite()->getId()); 

     $customer->loadByEmail($email); 

    // here i change the groupId 
     $customer->setData('group_id', 9); 
    // if i check the group here, the change applied ... 
     $customer_group = $customer->getGroupId(); 

     // i tried saving with following, but run into loop 
     $customer->save(); 

    } catch (Exception $e) { 
     Mage::log("newsletter_subscriber_change observer failed: " . $e->getMessage()); 
    } 
}

你有無限的循環，因爲Mage_Newsletter也捕捉customer_save_after事件以保存訂閱數據。 您可以通過原始查詢像波紋管更新組ID：

public function newsletter_subscriber_change($observer) { 
    try { 

     // get status of subscriber 
     $subscriber = $observer->getEvent()->getSubscriber(); 

     $status = $subscriber->getStatus(); 
     $email = $subscriber->getEmail(); 

     $customer = Mage::getSingleton('customer/customer'); 
     $customer->setWebsiteId(Mage::app()->getWebsite()->getId()); 

     $customer->loadByEmail($email); 

     $adapter = Mage::getSingleton('core/resource'); 

     /* @var $conn Varien_Db_Adapter_Interface */ 
     $conn = $adapter->getConnection('core_write'); 

     $update = 'UPDATE ' . $customer->getResource()->getTable('customer/customer_enity') 
       . ' SET group_id = ? WHERE entity_id = ?'; 

     $conn->query($update, array(9, $customer->getId())); 

    } catch (Exception $e) { 
     Mage::log("newsletter_subscriber_change observer failed: " . $e->getMessage()); 
    } 
}
