Modifying form validation script

Just wondering how I can modify the form and spelling validation script (by Matt Wade) so that when a user is returned to the form to edit incorrect fields the fields that were filled in correctly are not reset?
It works ok for text fields with

php Code:

Original - php Code
value="<?= $string ?>"

 value="<?= $string ?>"

but not for dropdown menus and radio buttons.
Any help would be much appreciated.

RE: Modifying form validation script

Might help if I post the script:

php Code:

Original - php Code

 
<?php
require_once ('functions.php');
 
$valid = TRUE;
 
if (isset ($_POST['submit'])) {
    foreach($_POST as $key=>$value) {
      $$key = $value;
    }
    $valid = $fn = checkLength($first_name, 1, 30);
    $ln = checkLength($surname, 1, 30);
    $valid = $valid && $ln;
    $un = checkLength($username, 1, 30);
    $valid = $valid && $un;
    $us = checkUsername($username);
    $valid = $valid && $us;
    $em = checkEmail($email_address);
    $valid = $valid && $em;
    $el = checkDatabase($email_address);
    $valid = $valid && $el;
    $ps = checkPassword($pass);
    $valid = $valid && $ps;
    $ps2 = $pass == $pass2;
    $valid = $valid && $ps2;
    $an = checkLength($acc_name, 1, 200);
    $valid = $valid && $an;
    $ad = checkLength($acc_address1, 1, 30);
    $valid = $valid && $ad;
    $pc = checkLength($postal_code, 1, 10);
    $valid = $valid && $pc;
    $ct = checkLength($city, 1, 30);
    $valid = $valid && $ct;
    $co = checkDropdown($country, 1, 30);
    $valid = $valid && $co;
    $tl = checkLength($tel, 1, 30);
    $valid = $valid && $tl;
    if ($valid) {
        include('register_acc2.php');
        exit;
    }
} else {
    $fn = $ln = $un = $us = $em = $el = $ps = $ps2 = $an = $ad = $pc = $ct = $co = $tl = TRUE;
    $first_name = $surname = $username = $email_address = $acc_name = $acc_address1 = $postal_code = $city = $tel = '';
}
?>
