Re: Sessions and iframes (or frames)?

My advice is to first get REALLY comfortable with sessions in a non-framed environment... get a grip on logging in, logging out, showing different code for logged in members, restricting a user from doing something more than once, etc etc. THEN try to get it happening in a framed environment. As discussed by John, you will have to force a refresh for any frame to be "aware" of a recently logged in user, and you will have to do a lot of checking when receiving a form or request in each of these frames, to ensure there is a user logged in, etc. As per ANY session stuff between pages, you need to propogate the session id either through the URL to each frame (or hope that trans-sid takes care of it), or rely on the user having cookies enabled. To point out the really obvious, <? session_start(); ?> needs to be called on the top of the script for EACH FRAME.
