I have some code that changes links once the user logs in, however it's not working properly. For example there is a link called "Register" (with the url/register.php) that should change to Member Area (with the url /member.php) once there is a valid session (the user has logged on) .. however it's not working, perhaps someone can see an error in the code?

This is for the Session check:

<?

if (!$special_mode)
{
$is_mem = $_SESSION["valid_user"];
?>

This is to do the switch:

<?
if ($is_mem <> "")
{
echo "<a href=\"http://$url/member.php\">$la_member_area</a>";
}
else
{
echo "<a href=\"http://$url/register.php\">$la_reg</a>";
}
?>

Nevermind I fixed it - thanks for nothing though!

Turns out I only hav PHP 4.0.6 which doesn't support $_SESSION and I had to use $HTTP_SESSION_VARS - ugh!
