About

This process takes place in /lib/page/ckout/content.php. I've gone back and forth between two possible confirmation processes:

• Render the confirmation from the Cart data; if approved, convert the Cart data into an Order and submit.
  • Advantages: creates fewer junk Order records
  • Disadvantages: If there's a bug in the order conversion, we might receive different order data than was approved by the user. Also, slightly harder to debug in that the problem shows up a step later
• Convert the Cart data into an order, then render the confirmation page from the Order data.
  • Advantages: ensures data integrity between what the customer approves and what we receive
  • Disadvantages: creates more junk Order records

Given this, I decided to keep both versions available and make it easy to switch between them. It may be that once the code is more mature/reliable, we will want to switch to the first method (confirm-from-Cart) -- but for now, it seems like the reliability of the second method is needed. Functions:

• RenderConfirm_fromCart() - confirm then convert
• RenderConfirm_fromOrder() - convert then confirm
• RenderConfirm() - dispatcher
