I have a two part question about customizing my Magento store.

When someone buys a downloadable product, I want to generate a licence code and include it in the invoice.

I have added a product attribute called ‘license_code’ to my product’s default attribute set and I want to set its value with php when a customer checks out.

Which event do I need to observe to let me access the products in the cart just after they are purchased but before the invoice is created?

Also, what script do I use to set a product’s attribute value durring that event?

Thank you for your help!

Hey CHeck out the Downloadable modules code.

in /app/code/core/mage/Downloadable/etc/config.xml you will see the events that it listens to.
These events cover order save, order_item_save. They are the events that you would need to use. If you need to do something before the order is saved, I believe that "sales_order_save_before" is the event.
<events>            
            <sales_order_item_save_after>
                <observers>
                    <downloadable_observer>
                        <class>downloadable/observer</class>
                        <method>saveDownloadableOrderItem</method>
                    </downloadable_observer>
                </observers>
            </sales_order_item_save_after>
            <sales_order_save_after>
                <observers>
                    <downloadable_observer>
                        <class>downloadable/observer</class>
                        <method>setLinkStatus</method>
                    </downloadable_observer>
                </observers>
            </sales_order_save_after>
        </events>

What is the licence code's purpose? Could you not use the hash that is created for every downloadable link?

I had to observe the sales_order_item_save_after event and then use the following functions to save the unlock code:

$orderItem = $observer->getEvent()->getItem();
$options = $orderItem->getProductOptions();
 $options['licence_code'] = 'unlock_for_item_'.$orderItem->getProductId();
$orderItem->setProductOptions($options);

I couldn't just use the hash for the download link because our game unlock codes have to be backward compatible with our old ecomm system.

Thank you for your help!
