Passing orderId to success.phtml

[Jakkara]

Im working on module that bypasses checkout if user is logged in and grand total is 0,00€.
Everything is working fine except for one thing.  On success page I don't see the order number.

It seems that in success.phtml $this->getOrderId() dosn't return anything.
I'm sure that I'm doing something wrong in my Observer.php:

class Myproject_Bypasscheckout_Model_Observer extends Varien_Object
{
    public function beforeCheckout(Varien_Event_Observer $observer)
    {
        // Get cart grand total
        $onepage = Mage::getSingleton('checkout/type_onepage');
        $quote = $onepage->getQuote();
        $quoteData = $quote->getData();

        // Bypass only if grand total is 0€ and user is logged in
        if ($quoteData['grand_total'] == 0 && Mage::getSingleton('customer/session')->isLoggedIn()) {
            $onepage->initCheckout();

            // Assign Customer To Sales Order Quote
            $customer = Mage::getSingleton('customer/session')->getCustomer();
            $quote->assignCustomer($customer);

            // Configure Notification
            $quote->setSendCconfirmation(true);

            // Set Sales Order Shipping Address
            $billingAddressData = Mage::getModel('customer/address')->load($customer->default_billing)->toArray();
            $billingAddress = $quote->getBillingAddress()->addData($billingAddressData);
            $shippingAddressData = Mage::getModel('customer/address')->load($customer->default_shipping)->toArray();
            $shippingAddress = $quote->getShippingAddress()->addData($shippingAddressData);

            // Collect Rates and Set Shipping & Payment Method
            $shippingAddress->setCollectShippingRates(true)
                ->collectShippingRates()
                ->setShippingMethod('freeshipping_freeshipping')
                ->setPaymentMethod('checkmo');

            // Set Sales Order Payment
            $quote->getPayment()->importData(array('method' => 'checkmo'));

            // Collect Totals & Save Quote
            $quote->collectTotals()->save();

            // Create Order From Quote
            $service = Mage::getModel('sales/service_quote', $quote);
            $service->submitAll();
            $incrementId = $service->getOrder()->getIncrementId();

            $checkout = $onepage->getCheckout();
            $checkout->setLastQuoteId($quote->getId());
            $checkout->setLastSuccessQuoteId($quote->getId());
            $checkout->setLastOrderId($incrementId);
            $checkout->setLastRealOrderId($incrementId);

            Mage::app()->getResponse()->setRedirect(Mage::getBaseUrl() . 'checkout/onepage/success')->sendResponse();
        }
    }
}

I don't see anything wrong so far, except you should wrap the order creating section with try .. catch ..., which is not related to your problem.

Did you check if $incrementId has value in the observer? which event this observer listen to?

[Jakkara · Accepted solution]

I'll add the try catch.

EDIT:
The event is controller_action_predispatch_checkout_onepage_index.

IncrementId does have value in it.

EDIT:
Just figured out what was wrong. Here is how it should be.

$orderId = $service->getOrder()->getId(); // Added this line
$incrementId = $service->getOrder()->getIncrementId();

$checkout = $onepage->getCheckout();
$checkout->setLastQuoteId($quote->getId());
$checkout->setLastSuccessQuoteId($quote->getId());
$checkout->setLastOrderId($orderId); // Not incrementId!!
$checkout->setLastRealOrderId($incrementId);
