You can use $_SESSION variables.

PHP $_SESSIONS

PHP Sessions and Cookies

So after the users has been validated set $_SESSION['surname'] = $surname;

Then on the top of each page add session_start(); to the top.

Then Under that add 

  if (isset($_SESSION['surname'])) {
      $surname = $_SESSION['surname'];
  } else {
      die();
  }

View the PHP docs for a more thorough understanding.

You may also want to look into setting up a MYSQL database if you want users to be able to create accounts.

Edit: form page

if($valid){
   $_SESSION['surname'] = $surname;
   $_SESSION['postalAddress'] = $postalAddress;
   header('Location: userdetail.php');
   exit();
}
