Adding extra fields on a PHP contact form

Hi all,

could somebody tell me how to add extra fields to the Kirupa Simple Email Form?

I need to add some extras in like telephone, addition info etc. and have them email through with an enquiry.The flash side of thing is straight forward but it’s the PHP i don’t get.

Here’s the PHP from the tutorial

$sendTo = "[email protected]";
$subject = "My Flash site reply";
$headers = "From: " . $_POST["firstName"] ." ". $_POST["lastname"] . "<" . $_POST["email"] .">
$headers .= "Reply-To: " . $_POST["email"] . "
$headers .= "Return-path: " . $_POST["email"];
$message = $_POST["message"];
mail($sendTo, $subject, $message, $headers);
