i'm trying to control a small online purchase page with some session arguments. i do have some bugs when i do this, probably it's because i'm no handaling all cases in the way i should .
lets say when a user logges in (after DB approve) i start a session, and add the username to the session array . but what happens if he/she clicks back? or closes the tab and then returnes ?
I think my questions are quite stupid, what i DO need is some detailed tutorial on session handeling .
plesae help guys!!
