Session Problems

[klycette]

I need some help with the basics of sessions. I've managed to start a session and register my visitors username and a session variable, but I'm having problems working out how to pass the seesion variable from one page to the next. From what I've read, sessions will try to make use of cookies, but if the person on the page has them disabled, you have to resort to embedding the session variable into the url.

In short, I need some help with this basic principle. If anyone could point me to some good tutorials or give me an easy example to work from, I'd really appreciate it. Thanks in advance.

once you start a session with session_start() register a session variable with lets say session_register, well you can access the session variable on any page as long as you have session_start(); at the top of the pages you want to keep the session on

What would the syntax be for accessing these session variables?
If cookies are disabled, can it still be done this way or do you have to embed the variable in the url. If so, what would the syntax for that be?

The syntax for accessing a session variable is
$_SESSION[varname]

this should work ok with cookies off also
