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.

<?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.';
}
$email = $_POST['epost'];
$pattern = '/^[^@]+@[^\s\r\n\'";,@%]+$/';
if (!preg_match($pattern, trim($email))) {
$error['epost'] = 'Vennligst skriv inn en gyldig e-post adresse.';
}
$company = trim($_POST['firma']);
if (empty($company)) {
$error['firma'] = 'Vennligst skriv inn ditt firmanavn.';
}
if (empty($_POST['platform'])) {
$error['platform'] = 'Vennligst velg platform.';
}
else{
$platform = trim($_POST['platform']);
}

if (empty($_POST['layout'])) {
$error['layout'] = 'Vennligst velg sideombrekkingsprogram.';
}
else{
$layout = trim($_POST['layout']);
}

if (empty($_POST['image'])) {
$error['image'] = 'Vennligst velg bildebehandlingsprogram.';
}
else{
$image = trim($_POST['image']);
}

if (!isset($error)) {
$sent = mail($to, $subject, $message, $additionalHeaders);
// check that the mail was sent successfully
if (!$sent) {
$error['ikkeSendt'] = 'Beklager, et problem oppsto. Vennligst pr&oslash;v igjen senere.';
}
}

}

put all radio values to new array, an do loop :

<?
$platform = array("PC", "MAC", "SOLARIS");
while(list($key, $value) = each($platform)) {
if($_POST['platform'] == $value) $checked = "checked";
print "<input type=\"radio\" name=\"platform\" value=\"$value\" $checked> $value";
unset($checked);
}
?>

this didn't work. you can check it out here:
http://www.waynemelrose.net/testing/thing.php

when you select mac and press send it doesn't validate because you didn't select any other fields and then i want it to remember that you selected mac and not go back to pc on the radiobutton.

yeah, u right.
Sorry, i don't know why, cause the script doesn't notice any errors in my localhost server (apache2)

i moved it to another server running apache... and it worked...

so now my new challenge is the textfields under the radiobuttons...
anyone know how i can make them remember only if the radiobutton hasn't been clicked???

cause when a user doesn't have neither mac nor pc they can write it in the textfield. and this also needs to be remembered... :cool:
