如何根据订单状态向magento中的卖家发送订单电子邮件

Question

我正在尝试仅在付款成功时向卖家发送订单电子邮件。我试过以下事件。

  

sales_order_place_after，sales_order_save_after，checkout_onepage_controller_success_action

我正在使用以下代码根据订单状态发送电子邮件，例如

if($order->getState() == Mage_Sales_Model_Order::STATE_PROCESSING){
        $emailTemp = Mage::helper('marketplace')->getOrderPlaceNotifymailTemplate();

        $emailTempVariables = array();

        $emailTempVariables['myvar1'] = $order->getRealOrderId();
        $emailTempVariables['myvar2'] = $order['created_at'];
        $emailTempVariables['myvar4'] = $billinginfo;
        $emailTempVariables['myvar5'] = $payment;
        $emailTempVariables['myvar6'] = $shipping_info;
        $emailTempVariables['myvar9'] = $shipping_des;
        $emailTempVariables['myvar8'] = $orderinfo;
        $emailTempVariables['myvar3'] = $Username;

        $processedTemplate = $emailTemp->getProcessedTemplate($emailTempVariables);

        $emailTemp->setSenderName($adminUsername);
        $emailTemp->setSenderEmail($adminEmail);
        $emailTemp->send($useremail,$Username,$emailTempVariables);
      }

但我无法发送电子邮件，即使我尝试使用

发送

  

if（$ order-＆gt; getBaseTotalDue（）== 0）{   .......电子邮件代码.........   }

如果我移除{}条件即使我取消付款网关上的付款我也可以发送电子邮件。我需要纠正这个问题，我只有在付款成功时才需要发送电子邮件。
