You're confused as to what globals are.

Global values are for use in a script that may require access to a value out of its scope but within that instance of the script:

PHP Code:

$Value = 'foobar';

function test()
   {
   print $Value; //Error - undefined variable type message
   }

function test2()
   {
   global $Value;
   print $Value; //Successful
   }

test();//Error
test2();//Success 


What you want to be using is SESSIONS. Sessions are remembered between scripts. To start or resume a session you use session_start. To store anything in the session or access a session value you use the $_SESSION array.

enter_new_pass.php:

PHP Code:

session_start(); //You MUST use this in every script that accesses a users session

$id = $_GET['id'];
$uniq = $_GET['unique'];

$_SESSION['id'] = $id;
$_SESSION['uniq'] = $uniq; 


do_new_pass.php:

PHP Code:

session_start();

$id = $_SESSION['id'];
$uniq = $_SESSION['uniq'];

print "$id, $uniq";
