Menu
i found the code below in a book. i have added the radio buttons and i am trying to validate them.
problem is if it doesn’t validate it forgets which radio button was chosen.
can someone help me make this code remember the chosen radio button just like it remembers the textfields.
any other comments to the code is also much appreciated.
[code=php]
<?php
$sent = false;
if (array_key_exists(‘fornavn’, $_POST)) {
$firstname = trim($_POST[‘fornavn’]);
if (empty($firstname)) {
$error[‘fornavn’] = ‘Vennligst skriv inn ditt fornavn.’;
}
$lastname = trim($_POST[‘etternavn’]);
if (empty($lastname)) {
$error[‘etternavn’] = ‘Vennligst skriv inn ditt etternavn.’;
