Is the url set at all, as your assigning the $uname var from the $_GET which is URL, $_POST is from a form, ensure you have it correctly assigned.

Yeah it was set, but at sometimes it wasn't! But now I deleted almost everything to do a fresh start, I noticed I messed up every code I had haha Anyone know how you do a "Profile Page"? I want to do, if($_SESSION["username"] == $_GET["uname"]){

echo "Edit your information";

}

else{

echo "Checking someone elses profile";

}

Here's my code:

<html>
<head>
<style type="text/css" media="all">
@import url("style.css");
</style>
</head>
<body>
<div id="header">
<h1><a href="index.php">ProjecTM</a></h1>
</div>
<div id="menu">
<ul>
<a href="index.php">News</a>
<a href="guestbook.php">Guestbook</a>
<a href="changepassword.php">Change Password</a>
<a href="logout.php">Log out</a>
</ul>
</div>
<?php
include("dbconnect.php");
session_start();
echo "<div id=\"homeform\">";
if(isset($_SESSION["username"])){
$link1 ='
<a href="members.php?uname&changeinfo=' . $_SESSION["username"] . '"> Change information </a>';
if($_SESSION["username"] == isset($_GET["uname"])){
echo "hello";
}
elseif ($_SESSION["username"] != isset($_GET["uname"])) {
echo "goodbye";
}
}
echo "</div>";
?>
</body>
</html>
