How can I sell access to certain parts of my site?

[metroid9824]

Is there a way to make it where when the person has bought an item(and the order is confirmed) it executes a script of my coding?

Heres what I am trying to do. I am selling access to certain parts of my website. The user can by 1 day 1 week, etc. But I don't know how I can implement that using Zen Cart without human interevention. Any ideas?

I am thinking that I can submit there login info and there order, from Zen Cart to another database that I can easily program with.

Has this been answered elsewhere?
