[PHP] Using $_SESSION vs. session_register

I have a large-ish backend that I made with the (now deprecated) session_register, session_is_registered, session_unset, session_destroy functions.

Now I've made a frontend for that backend using the superglobal $_SESSION instead, setting session variables like so:

PHP Code:

---

$_SESSION["UID"] = $row['userid'];
$_SESSION["LAST_TS"] = $row['last_login']; 


---

after these are set, the login script redirects to the site frontpage (using the header function), where I check these variables to decide what parts to display. However I can't access them / they are empty! I know that they do get set though, because I can access the backend without logging in there as well (same credentials), and I can also logout successfully (using unset()). So I'm wondering why are they not available to me on the frontpage?

I did read in the PHP manual that you are not supposed to use the old session functions with the new $_SESSION superglobal, but I don't in the frontend scripts. I do in use these functions in the backend but they are not really connected.. they include the same headers.php file, and functions pages, but these don't use session variables, just session_start() and ob_start().

If I've made myself understood, are there any suggestions?

Lol, I thought I was having deja vu! Remember August of 2003? http://sharkyforums.com/showthread.p...hreadid=201871

Are you sure that the recordset returned from the database actually has data in it this time? :)

Either way, I would start debugging it by placing calls die($_SESSION['UID']) in various places to see where it gets lost.

Hehe. I can't remember what I was working on that time, but I do get the values from the db this time. Wierd thing is I usually find the error after posting here, but this time it has taken a long time..

PHP Code:

// login.php file
// include headers:
require("admin/headers.php");


// login routine:
if (isset($_SESSION["UID"])) {
    header("Location: /");
} else {
    if (isset($_POST['username']) && isset($_POST['passwd'])) {    
        require($unixpath."wcms/inc/db.inc.php");
        $query = "select * from wcms_user where username='$_POST[username]' and passwd=password('$_POST[passwd]') limit 1";
        $result = mysql_query($query);
        if (!$result) {
            create_header($lang['Login']);
            print $lang["NoResultReturned"];
            $errorTxt = mysql_error();
            errorlog($errorTxt, $PHP_SELF);
        }        
        $num_results = mysql_num_rows($result);
        if ($num_results != 1) {            
            create_header($lang['Login']);
            echo "<h1>".$lang['Login']."</h1>";
            print "<p>" . $lang['CouldNotLogin'] . "<br>";

        else {
            $row = mysql_fetch_array($result);
            $_SESSION["UID"] = $row['userid'];
            $_SESSION["LAST_TS"] = $row['last_login'];            
            $new_ts = time();        
            $db_update = mysql_query("update wcms_user set last_login='$new_ts', total_logins=total_logins+1 where userid='".$_SESSION['UID']."'");
            if (!$db_update) {
                $errorTxt = mysql_error();
                errorlog($errorTxt, $PHP_SELF);
            }        
            // try including the mypage here instead of redirecting:
            // header("Location: /");
            create_header($lang['Login']);
            include ("mypage.php");
        }                                 
    } else {
        // missing pw or username, do something:
        echo "Missing username/passwd";
    }
    create_footer();    
}
?>
