[PHP] Cookies/Sessions not liking each other...

[Tanus]

For some reason, I can't register a variable that has been taken from a cookie, as follows...

PHP Code:

<?
    session_start();
    
    CheckCookies();

    echo "Session info is ".$_SESSION["username"];

    function CheckCookies()
    {
        if($_SESSION["username"]) {
            return;
        }
                
        else if($_COOKIE["utsource"]) {
            $ck = explode("TA-N-US", $_COOKIE["utsource"]);
            $username=$ck[0];
            $password=$ck[1];
            session_register("username");
            session_register("password");
        }
        return;
    }

?>

For some reason, the $_SESSION["username"] field is blank when I call for it immediately after registering it. Is there something about handling cookies and sessions that I'm not getting? If I put an echo before the session registers, the username is there and correct, same with password (I know you can't output before registering a session, it's not working when that echo isn't there).

It isnt working because session_register() is out of scope. You would have to define username and password as globals to use it inside the function.

But theres no need to use session_register(). Its simpler and safer to assign the superglobal directly $_SESSION["username"] = $ck[0].

That's what I've done to get it working in the end, but even if I just returned $ck above it and then tried to register stuff it'd crack the sads. Oh well, works now .
