Magento - 如何停止付款交易失败的发票订单

Question

I am using custom payment module and upon receiving failed transaction response from my custom payment gateway I would like to

• save the order with "pending_payment" state/status and not send any order email.

• I do not want to create any invoice /process it or send any invoice email.

• Also I would like to redirect my customers to a failure page or maybe checkout/cart page but with a message at the top saying their payment details was erroneous, and please try again.

Once I receive a 'Failed' response from my payment gateway I am able to save the order to pending_payment status and stopping it form sending a new order email but I'm not able to stop it from invoicing n hence stop d invoice email from being sent out.

I'm calling an Observer on sales_order_place_after event in my custom payment module which invoices the orders and sends the invoice email on successful transactions.

Now I dont know if that file needs editing too(app/code/local/Mage/Paymentmodule/Model/Observer.php) or just my app/code/local/Mage/Paymentmodule/Model/PaymentMethod.php is enough for this.

PaymentMethod.php

      public function capture(Varien_Object $payment, $amount) 
      {
        $error = false;
    // check for payment
   if($amount > 0)
   {
    $payment->setAmount($amount);
    $order = $payment->getOrder();
    if($payment->getTxnNumber() == "")
    {
        $transaction = $this->_build($payment, self::TRANSACTION_PREAUTH);
            $authResponse = $this->_send($transaction);
        if($authResponse->getResponseCode() > 0 && $authResponse->getResponseCode() <= self::ERROR_CODE_LIMIT)
        {
            $payment->setCcApproval($authResponse->getReceiptId())
             ->setLastTransId($authResponse->getReceiptId())
             ->setCcTransId($authResponse->getTxnNumber())    ->setCcCidStatus($this->getCvdDescription($authResponse->getCvdResultCode()));    

        }
        else if($authResponse->getResponseCode() > self::ERROR_CODE_LIMIT && $authResponse->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT)
        {
           $order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
           $order->setCanSendNewEmailFlag(false);
           $order->setCanInvoiceFlag(false);
        }
        else
        {
           $order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
           $order->setCanSendNewEmailFlag(false);
           $order->setCanInvoiceFlag(false);
        }
    }
    $check = $this->checkCvdResponse($authResponse->getCvdResultCode());
    if($check == true)
    {
        $order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
        $order->setCanSendNewEmailFlag(false);
        $order->setCanInvoiceFlag(false);
    }
    else
    {
        $transaction_completion = $this->_build($payment, self::TRANSACTION_COMPLETION);
        $response = $this->_send($transaction_completion);  
        if($response->getResponseCode() > 0 && $response->getResponseCode() <= self::ERROR_CODE_LIMIT) 
        {
            $payment->setStatus(self::STATUS_SUCCESS);
            $payment->setCcApproval($response->getReceiptId())
             ->setLastTransId($response->getReferenceNum())
             ->setCcTransId($response->getTxnNumber())
             ->setCcAvsStatus($this->getAvsDescription($authResponse->getAvsResultCode()))
             ->setCcCidStatus($this->getCvdDescription($authResponse->getCvdResultCode())); 
        }    
        else if($response->getResponseCode() > self::ERROR_CODE_LIMIT && $response->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT) 
        {
            $order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
            $order->setCanSendNewEmailFlag(false);
            $order->setCanInvoiceFlag(false);
        } 
        else 
        {
           $order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)                                       ->save();
           $order->setCanSendNewEmailFlag(false);
           $order->setCanInvoiceFlag(false);
        }
    }
} 
else
{
    $error = Mage::helper('paygate')->__('Invalid amount for authorization.');
}
if ($error !== false)
Mage::throwException($error);
    return $this;
 }

Observer.php

   public function implementOrderStatus($event)
  {
    $order = $event->getEvent()->getOrder();    
    if ($this->_getPaymentMethod($order) == 'custompaymentmodule') 
    {
        if($order->getState() == 'pending_payment')
        {
          $order->setCanSendNewEmailFlag(false);
          $order->setCanInvoiceFlag(false);
        }
                 if ($order->canInvoice())

            $this->_processOrderStatus($order);
    }
    return $this;
}

Any ideas how can I just save it pending_payment state and stop it form invoicing and redirect to cart page with an appropriate message.

Any help on solving any of the bits would be highly appreciated. Thanks

Answer 1

I found a partial solution to my problem. On failed payment transactions, instead of setting the pending_payment state in my PaymentMethod.php, I'm setting the Payment status to Declined and setting CcTransId to NULL

Then using this condition in my Observer.php I'm saving that order with pending_payment status.

Here's d modified code

PaymentMethod.php

   if($payment->getTxnNumber() == "")
   {
      <!-- SOME CODE -->
      if($authResponse->getResponseCode() > 0 && $authResponse->getResponseCode() <= self::ERROR_CODE_LIMIT)
      {
        <!-- SUCCESSFUL TRANSACTION CODE   
      }
      else if($authResponse->getResponseCode() > self::ERROR_CODE_LIMIT && $authResponse->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT)
      {
         $payment->setStatus(self::STATUS_DECLINED);
      }
      else
      {
         $payment->setStatus(self::STATUS_DECLINED);
      }
   }
   $check = $this->checkCvdResponse($authResponse->getCvdResultCode());
   if($check == true)
   {
       $payment->setStatus(self::STATUS_DECLINED);
       $payment->setCcTransId(NULL);  
   }
   else
   {
       $transaction_completion = $this->_build($payment, self::TRANSACTION_COMPLETION);
       $response = $this->_send($transaction_completion);  
       if($response->getResponseCode() > 0 && $response->getResponseCode() <= self::ERROR_CODE_LIMIT) 
       {
          <!-- SUCCESSFUL CAPTURE -->   
       }    
      else if($response->getResponseCode() > self::ERROR_CODE_LIMIT && $response->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT) 
      {
         $payment->setStatus(self::STATUS_DECLINED);
         $payment->setCcTransId(NULL);  
      } 
      else 
      {
        $payment->setStatus(self::STATUS_DECLINED);
        $payment->setCcTransId(NULL);  
      }
}

Observer.php

    public function implementOrderStatus($event)
    {
      $order = $event->getEvent()->getOrder(); 
      if ($this->_getPaymentMethod($order) == 'custompaymentmodule') 
      {
     if($order->getPayment()->getCcTransId() == NULL)
     {
        $state = 'pending_payment';
    $status = 'pending_payment';
    $comment = 'Payment transaction failed due to incorrect AVS/CVD details.';
    $isNotified = false;
    $order->setState($state,$status,$comment,$isNotified)->save();
        $order->setCanSendNewEmailFlag(false);
         }
         else
         {
             <!-- SUCCESSFUL INVOICE CODE -->
         }
      }

The only thing I'm left now with is to redirect the user to Shopping Cart page with an erro message at the top.

However since I need to do all this in Observer file, I'm not able to call $this->_redirect() method. Tried Mage::app->getResponse->setRedirect(Mage::getUrl('checkout/cart')) but dint work.

Any ideas on how to accomplish this last bit. }
