I wish to upgrade my ancient Contact Form to a new form as sample of which is positioned at .php here and .html positioned here. It is however presenting a 500 error. What is the error advising of and what might be the resolve so that I can progress with the upgrade? The error log presents the following information on Undefined variables:

<?php
// we must never forget to start the session
session_start();
?>
<?php
define("EMAIL", "xxxxxxxxx@xxx.xxx");
if(isset($_POST['submit'])) {
include('validate.class.php');
//assign post data to variables
$name = trim($_POST['name']);
$email = trim($_POST['email']);
$message = trim($_POST['message']);
//start validating our form
$v = new validate();
$v->validateStr($name, "name", 3, 75);
$v->validateEmail($email, "email");
$v->validateStr($message, "message", 5, 1000);
if(!$v->hasErrors()) {
$header = "From: $email\n" . "Reply-To: $email\n";
$subject = "Contact Form Subject";
$email_to = EMAIL;
$emailMessage = "Name: " . $name . "\n";
$emailMessage .= "Email: " . $email . "\n\n";
$emailMessage .= $message;
//use php's mail function to send the email
@mail($email_to, $subject ,$emailMessage ,$header );
//grab the current url, append ?sent=yes to it and then redirect to that url
$url = "http". ((!empty($_SERVER['HTTPS'])) ? "s" : "") . "://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
header('Location: '.$url."?sent=yes");
} else {
//set the number of errors message
$message_text = $v->errorNumMessage();
//store the errors list in a variable
$errors = $v->displayErrors();
//get the individual error messages
$nameErr = $v->getError("name");
$emailErr = $v->getError("email");
$messageErr = $v->getError("message");
}//end error check
}// end isset
?>
