Sharing PHP variables ($_SESSION question)

[RodG]

I'm writing a PHP script to communicate with Amazon for their fulfillment service. The script needs to access information that Zen Cart stores in the $order variable.

Q1) How does Zen Cart preserve and make a variable like $order accessible across pages?

Either via the GLOBALS (classes) or the $_SESSION variables.

Q2) Any idea why session_start() creates a new session instead of resuming?

Because session_start() literally starts a new session. Clearly this isn't what you want since ZenCart already has a session started.

At the start of you module functions add

global $order ;

Retrieve values using code like:

$myPostcode = $order->delivery['postcode']
