Passing varibles

Anon

I ran into a problem which I can't find the solution to. I have a page where a user logs on, and selects one of two choices. Depending of the choice, he's redirected (via header ("location:")), but the page he ends up on doesn't have the user/password variables sat, since they get lost in the http redircect.

How can I get a variable to be 'global' (I think there was some global session thingies to use, but I can't find them in the manual...)?

eg: if in your authentication script you have - ' $user_id=strtolower($PHP_AUTH_USER); '(or similar ,you may be using a different variable name)

then in your page ,
$ID=$user_id;//ASSUMING SUCCESSFUL LOGIN//

but you still have to pass the $ID from page to page.

Well, duh... =)

I of course meant how do I pass $ID from page to page, when I use a HTTP redirect. I can't use a "location: page.php3?id=$id", since I'm passing 'secret' data, and I can't use <input type=hidden> and method=post, since I'm not using a form...

I think I've solved it by not redirecting, but include()'ing the page they should go to. But it's not my prefered solutiuon.

or you can give the user a cookie - either with the id/pass or a uniquid() set when the user signs on and attatched to the db.?? just thinking out loud.

Well, I could... Right now, I've solved the main problem. But I still want to know if there is a way to pass variables around through HTTP.
