Variables

[ghostta]

When people log into my site by clicking submit, they are passed to a authenitcation page which if they pass directs them to the internal site.  What I would like to do is have a few variables that are global across all the logged in pages they access like their company logo and name.  How do I do this?  I tried $GLOBALS['xxx'] but it doesn't seem to stick beyond the page they are assigned.

Ya, I thought about sessions.  But the other problem I had with sessions is the across all the pages I could access my session variables like $_SESSION['xxx'] but if I tested for the session id like session_id() == "" that would always come back true.  Is it possible to have sesssion_id() return an empty string but still access $_SESSION['xxx']?  I was worried there was an underlying bigger problem that would affect me down the road.

Did you test session_id() before or after session_start() ?

I had two function that did it for me.  The auth page would call the function that would start the sesssion and register the vars.  The page it directed you to would then call the check function which would do:

 

if ( session_id() == "" )

 

But that would always result in true.

You need to start session on every page that will use session variables.
