Hi, I searched an found some similar topics posted in the past but they didn't solve my problem. Here is my issue:

I created a custom PHP file:

/includes/modules/mymodule/test.php for example.

Now on the checkout page I have some JavaScript that makes an AJAX call to test.php to load some data. This works great, except that in test.php I cannot access the session object. I need to get the customer ID from the session. I also need to secure the page to ensure that anyone that accesses it is logged in.

Any ideas on how to access the session from custom PHP pages?

Thanks
