Problems with sessions not passing via url

[themanic]

I'm having problems with storing and manipulating a variable in a session. I cut it down to the simplest code I could and it's still not working. Here's what I have:

<?
session_start();
session_register("MANICSHIFT_MONTH");
if ($MANICSHIFT_MONTH == "") $MANICSHIFT_MONTH = 6;
print $MANICSHIFT_MONTH;
?>

<a href="./test.php?MANICSHIFT_MONTH=<? print ($MANICSHIFT_MONTH - 1); ?>">BLAH</a>

That's the whole file. When I test it out, it shows the value of $MANICSHIFT_MONTH as 6 and has a link (BLAH) which points to test.php?MANICSHIFT_MONTH=5 and appends the sessionid to the end. When I click on the link, it comes back with $MANICSHIFT_MONTH still set as 6, and the link still says =5, but it no longer appends the sessionid to the end. What's going wrong?

$MANICSHIFT_MONTH will still be set to 6 in your session because you are only creating a new GET variable that is set to 5, that alone won't update your session variable.

What he said

And why do'ntuse the superglobal $_SESSION
instead of session_register() ?

[devinemke]

And why do'ntuse the superglobal $_SESSION

assuming you are using PHP >= 4.1.0

Many thanks, you were right.

I don't know, it just seems like either way works, $_SESSION or session_register. Is there any pros/cons of either of them that would be of interest to me?

[devinemke]

session_register() and HTTP_SESSION_VARS are depreciated and will presumably be gone in future releases of PHP.

Aite. I switched it over to $_SESSION. You talked me into it. Thanks guys
