Adding AJAX and working with $_SESSION

[CreativePixel]

Hi, all.

 

I want to add some custom AJAX (from scratch) to my catalog. I have two challenges:

 

1)If I put my PHP processor file (ajax_functions.php) in any directory other than the catalog (such as catalog/includes/functions), the response text is the HTML for the page that says 'you don't have access' (just as if a user was to enter the url for the PHP file directly into their browser). So how do I let my AJAX functions access the processor file, without putting it in an unprotected directory?

 

2)Where do I need to put my processor file so that it can access the catalog's $_SESSION variables? Right now, my PHP processor includes session_start(); and I'm using the regular $_SESSION[name] to attempt to access them, but it always returns null. Is there an OSC-specific way of accessing them or something?

 

Thanks.
