Login and Logout

[Knuckles]

Hello,

 

I have made a logout script with a existing login script i already had. Now when i try to logging it doesnt do anything anymore. 

 

I attached the login and logout.php. 

 

logout.php

login.php

Post the relevant code in code tags rather than posting the files, please.

There you go.

 

Logout.php

<?php
if(isset($_COOKIE['cookie_name']) {
  unset($_COOKIE['cookie_name']);
  setcookie('key', '', time() - 3600); 
}
header("Location: http://test.com");
?>

Login.php

Your going to need to at least attempt to narrow your issue down somewhat. Posting a bunch of code and saying "this doesn't work" does nothing to help us help you.

The issue im having is that if i enter the login details and try to log in it  refreshes the same page instead of going to another page.

 

As i put in the code its suppose to go to test.test.com instead of coming back in test.com.

 

Not sure if this helps anything
