I'm not sure if it is the proper terminology to use for what I mean, but I want a variable that can be sent to pages several layers deep. For example: I want to create a variable "username" that can be sent to not only the next page that it encounters (which I am doing right now with $HTTP_POST_VARS), but also to the next page after that. Every page after the "login" page should remember what the username is, but I don't want to have to send it each time. I want to be able to just call upon it anytime I wish by the name ($username). I doubt it is this simple though. I'm not sure if cookies need to be involved or not. Any help is GREATLY appreciated!!
