Session data doesn't appear to be reaching a second PHP program.

The first program contains the following:
session_start();
$valid_user = $user;
echo "Registering ".$valid_user.".";
session_register("valid_user");

The second program has the following:
<?
echo "Userid=".$valid_user.".http".$HTTP_SESSION_VA RS["valid_user"].".";
// check that user is logged on
if (session_is_registered("valid_user")) {
echo "Userid: ".$valid_user;
}
else
{
echo 'Please <a href="login.php">logon</a>';
return;
}
...
?>

The output is as follows:

Registering admin.

When I click onto the link to the second program, the following output is produced:

Userid=.http.Please logon

I'd be very grateful for any help.

Which version of PHP are you using and do you have access to the PHP.INI file? The use of http_session_vars and session_register have been deprecated in more recent releases.

That's quite simple - you haven't restarted your session in the second document so the data
isn't seen.

Use

session_start();

in the very beginning of the second "program" and that should work fine. If it doesn't, let us know because as cptnwinky has written, session_is_registered and $HTTP_SESSION_VARS are depreciated...

Wow, I missed that all together. Good eye pitbull.

Adding the session_start(); fixed it.

Thanks very much.
