I think that the echo ('Location: ...'); has to be in the <head> part of the document. And I think that it should be: header ('Location: ...'); from my knowledge at least. Also same with the cookies, in the <head> part of the document.
Also just a tip:

PHP Code:


print ("Username/Password Invalid");
die();

Make it this:

PHP Code:


die("Username/Password Invalid");

Same for the print() below it.

Nile is partly correct. The setcookie and header parts need to be placed before anything is outputted to the browser. Basically, you would need to do something like the following:

index.php

Code:

<?php
/* These are our valid username and passwords */
$user = 'test';
$pass = 'test';
if (isset($_COOKIE['username']) && isset($_COOKIE['password'])) {

 if (($_POST['username'] != $user) || ($_POST['password'] != md5($pass))) {
  header('Location: newlogin.php');
 }
 else {
  $welcome = 'Welcome back ' . $_COOKIE['username'];
 }

}

else {
 header('Location: newlogin.php');
}
?>
