Question

This must be so simple, but I am just not getting forward.

I initiate a session and use the normal PHP Session handler using a cookie.

I now have a upload form which is using a Flash uploader. Unfortunately the Flash uploader is not reading the cookie from the session and opening a new session as the Flash is running in its own instance.

So I have written a workaround which is passing me the session variable in a GET parameter.

Reading the session ID from the get parameter works perfectly.

$SID = $_GET['session'];

session_start();
session_id($SID);

$dataFromSession = $_SESSION['data'];

Unfortunately $dataFromSession / $_SESSION['data'] seems to be empty.

This must be the most simple thing ever…

Thanks

If id is specified, it will replace
the current session id. session_id()
needs to be called before
session_start() for that purpose.

You call session_id() after session_start(). That could be the problem for example?
