User Authentication/Cookies

[woodmuse]

I've got this code, I'm trying to make work for an authentication method for a site I'm developing. Right now, the code enters into an infinite loop going to index.php then to home.php and back again. Can someone direct me down the correct path? Thanks.

$address = "http://localhost/beta/ch";
$email = "[e-mail]";
$cn = mysql_connect("localhost","root","");
$db = mysql_select_db('db);
$user = "$username";

if (!isset($HTTP_COOKIE_VARS["$user"])) {
$cn;
$db;
$result = mysql_query("select * from table where username = '$username' and password = '$password'");
if ($result){
setcookie("clubhouse", "$user");
header("Location:$address/home.php");
} else {
header("Location:$address/index.php");
};
};

Note that the first paremeter of setcookie() is its name!
So in order to receive the cookie data you must use $HTTP_COOKIE_VARS[$cookiename]

setcookie("clubhouse", $user) ; 
$cookie = $HTTP_COOKIE_VARS["clubhouse"] ; // $cookie now contains the value of $user
