Help With Login Script

[Amster]

I am using the php-login script. Everything has been working fine but suddenly now when I try logging in with an account (called user1) that has always worked previously, it simply redirects me to the login page. It does not error, it just redirects. Although if I try another account (user 2), I login normally but this one account (user 1) just does not seem to not want to login and just keeps redirecting me back when I try logging in.

 

Also, the script only works if I have the "Remember Me" box checked. I have a feeling that it is an issue with cookies, I have taken a code snippet here:

 

session_start();
session_regenerate_id (true); //prevent against session fixation attacks.
// this sets variables in the session
$_SESSION['user_id']= $id;
$_SESSION['user_name'] = $full_name;
$_SESSION['user_level'] = $user_level;
$_SESSION['HTTP_USER_AGENT'] = md5($_SERVER['HTTP_USER_AGENT']);

//update the timestamp and key for cookie
$stamp = time();
$ckey = GenKey();
mysql_query("update users set `ctime`='$stamp', `ckey` = '$ckey' where id='$id'") or die(mysql_error());

//set a cookie

if(isset($_POST['remember'])){
 setcookie("user_id", $_SESSION['user_id'], time()+60*60*24*365, "/");
 setcookie("user_key", sha1($ckey), time()+60*60*24*365, "/");
 setcookie("user_name",$_SESSION['user_name'], time()+60*60*24*365, "/");
 }
header("Location: myaccount.php");

 

Although, it may be other things. For further reference, the script I am using is from here: http://php-login-script.com

 

Thanks!

You say it just redirects you to login page with no errors... Try commenting out all header() lines, and put error messages in their place instead.

 

Then post back here and tell us what the error is.

 

//error message
echo "Error: ".mysql_error();

You have no code to validate the login information, or set the user data in the session, in the snippet above. Either you've removed way too much from your code, or that is your problem.

In the posted code, the header() is unconditional; it will redirect regardless of what happens elsewhere in the script. An exception may be if an error message is generated. If that is happening, the header() call would generate a 'headers already sent' error instead of redirecting.
