阻止訂閱者保存在觀察者newsletter_subscriber_save_before Magento

我創建了一個Observer來監視事件subscriber_save_before。在這個觀察者中，我處理一個新的字段，保存這個字段的值，但是如果發生了一些錯誤，我想記錄不要保存，只顯示我的錯誤信息。 throwException似乎沒有辦法。我認爲唯一可行的方法是強制電子郵件字段爲空，但無法實現此目的。在subscriberController.php（法師核心）我有這樣的：阻止訂閱者保存在觀察者newsletter_subscriber_save_before Magento

$email = (string) $this->getRequest()->getPost('email'); 

     try { 
      if (!Zend_Validate::is($email, 'EmailAddress')) { 
       Mage::throwException($this->__('Please enter a valid email address.')); 
      }

這是我的代碼（不工作）：

public function NewsletterSaveSubscriber($observer) 
{ 
    $subscriber = $observer->getEvent()->getSubscriber(); 
    $name = Mage::app()->getRequest()->getParam('subscriber_name'); 



    // server side validation 
    // no name specified 
    if (!Zend_Validate::is(trim($name), 'NotEmpty')) { 

     $session = Mage::getSingleton('core/session'); 

     try { 
      Mage::throwException(Mage::helper('newsletter')->__('The name field cannot be empty!')); 
     } catch (Mage_Core_Exception $e) { 
      $session->addException($e, Mage::helper('newsletter')->__('There was a problem: %s', $e->getMessage())); 
     } 
    $observer->getRequest()->setPost('email', ''); // this code doesn't work 
    Mage::app()->getRequest()->setPost('email', ''); // this too 

      // Ohh nooo! The subscriber is stored :-(
     return $this; 
    } 


    // save the name 
    $name = htmlspecialchars($name); 
    $subscriber->setSubscriberName($name); 
    return $this; 
}

您需要添加重定向語句。如果您的電子郵件無效，或者您希望執行代碼並在下一頁顯示您的消息，您是否希望重定向？ – oscprofessionals 2013-03-19 04:42:05

這將解決您的probem：

//Error Message 
$session = Mage::getSingleton('core/session'); 
$session->getMessages(true); 
$session->addError(Mage::helper('cartware_automaticreview')->__('Could´t save.')); 

// Ohh nooo! The subscriber is not stored :)    
$controller = $observer->getControllerAction()->setFlag('',Mage_Core_Controller_Varien_Action::FLAG_NO_DISPATCH,true); 
$controller->getResponse()->setRedirect(Mage::app()->getRequest()->getServer('HTTP_REFERER')); 
return;

祝你好運！
