Use session variables.
Page 1) Login Page
<input name="uesrname">
<input name="password">
Page 2) Processing Page
<?php
session_start();
session_register("username");
session_register("password");
print("Login name = $username\n");
print("Login pass = $password\n");
?>
Page n) ANY PAGE !
<?php
session_start();
print("Login name = $username\n");
print("Login pass = $password\n");
?>
Now, everytime you call $username or $password, it will spit out what they first entered, without a form. This is possible AS LONG AS YOU DELCLARE session_start(); AT THE BEGINNING OF EACH PAGE ON WHICH YOU WANT THE VARIABLE(S) TO SHOW UP !
