Any reason why this code snippet wouldn't set a cookie properly?

Question

This little PHP snippet is used to set a cookie that lets me determine whether or not a user is logged in. For some reason, after I use the javascript to redirect, none of my cookies are set any more. Any reason why this would be happening?

I may not be giving you enough info so let me know if so.

...some database queries...
<?php 
    $expire=time()+(7 * 24 * 60 * 60);
    $row = mysql_fetch_array($query);
    $email = $row['email'];
    $userinfo['name'] = $name;
    $userinfo['email'] = $email;
    $userinfo = serialize($userinfo);
    setcookie("user", $userinfo, $expire);
    echo '<script type="text/javascript">
        window.location = "../index.php";
    </script>';

?>

Tory, make sure you do not output anything before you call set setcookie in PHP. Not even white space. No echo. Nothing. What I guess is your scripts outputs some thing before setcookie and that breaks your script. Do you see header already sent error? Comment out your JS and then check. You setcookie in this way

setcookie(name,value,expire,path,domain,secure); 

Domain needs a domain name value in string like example.com, its optional. Secure needs a boolean value and is optional. Skip these two and check by setting path to '/'
