How to mark an order failed programmatically - Magento - php

Question

I would just like to know what is that one property which when set would mark the order as failed so that failureAction() of app/code/core/Mage/Checkout/controller/OnepageController.php gets called.
I have an Observer.php where in I'm creating invoice for successful payments and for failed payments saving order with pending_payment status and wanting to redirect them to the cart page with an error message at the top.
All this happens fine. Just that for unsuccessful / failed payments, along with saving the order with pending_payment status n redirecting them to cart page with error message, I would also like to retain/save the cart from getting empty.
But to no luck
Observer.php
public function implementOrderStatus($event)
{
$order = $event->getEvent()->getOrder();
if ($this->_getPaymentMethod($order) == 'mypaymentmodule')
{
$quote = Mage::getModel('sales/quote')->load($order->getQuoteId());
if($order->getPayment()->getCcTransId() == NULL)
{
$order->cancel();
$order->setStatus('canceled');
$order->save();
$quote->setIsActive(1)->save();
/*$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();
$order->setCanSendNewEmailFlag(false);*/
Mage::getSingleton('checkout/session')->addError('Sorry, either of your card information (billing address or card validation digits) dint match. Please try again');
Mage::app()->getFrontController()->getResponse()->setRedirect('checkout/cart/')->sendResponse();
}
else
{
if ($order->canInvoice())
$this->_processOrderStatus($order);
}
}
return $this;
}
But $quote->setIsActive(true)->save() does not seem to be doing the trick. Any help as to how can I save my cart from getting empty after saving the order with 'canceled' status.

You maybe should have a look at ./app/code/core/Mage/Sales/Model/Order.php. There you will find several constants for an order, which may be used to set the state of an order like this:
<?php
// [...] all your code within your custom action or script
//load your order by order_id (or by increment_id, if you like to, here, it's your order id
$order = Mage::getModel('sales/order')->load($your_order_id);
$order->setState(Mage_Sales_Model_Order::STATE_CANCELED); //or whatever distinct order status you'd like
$order->save();
The failureAction in the controiller action does nothing of the sort, if you want to call it manually, you can build it's url using Mage::getUrl()
