Might be easier to look at this fiddle: http://jsfiddle.net/pkAGz/ and the process.php code is shown below:
<?php
//Retrieve form data.
//GET - user submitted data using AJAX
//POST - in case user does not support javascript, we'll use POST instead
$name = ($_GET['name']) ? $_GET['name'] : $_POST['name'];
$email = ($_GET['email']) ?$_GET['email'] : $_POST['email'];
//flag to indicate which method it uses. If POST set it to 1
if ($_POST) $post=1;
//Simple server side validation for POST data, of course,
//you should validate the email
if (!$name) $errors[count($errors)] = 'Please enter a name.开发者_如何学编程';
//if the errors array is empty, send the mail
if (!$errors) {
$name = $name[array_rand($name)];
$to = '$name <$name email adress if set>';
//sender
$from = $name . ' <' . $email . '>';
//subject and the html message
$subject = 'Comment from ' . $name;
$message = '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>
<table>
<tr><td>Name</td><td>' . $name . '</td></tr>
<tr><td>Email</td><td>' . $email . '</td></tr>
</table>
</body>
</html>';
//send the mail
$result = sendmail($to, $subject, $message, $from);
//echo "\n\n$name has been nominated to make the tea!\n\n";
//echo "\n\nThey will also be notified by e-mail if you entered their address.\n\n";
//if POST was used, display the message straight away
if ($_POST) {
if ($result) echo "\n\n$name has been nominated to make the tea!\n\nThey will also be notified by e-mail if you entered their address.\n\n";
else echo 'Sorry, unexpected error. Please try again later';
//else if GET was used, return the boolean value so that
//ajax script can react accordingly
//1 means success, 0 means failed
} else {
echo $result;
}
//if the errors array has values
} else {
//display the errors message
for ($i=0; $i<count($errors); $i++) echo $errors[$i] . '<br/>';
echo '<a href="index.php">Back</a>';
exit;
}
//Simple mail function with HTML header
function sendmail($to, $subject, $message, $from) {
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= 'From: ' . $from . "\r\n";
$result = mail($to,$subject,$message,$headers);
if ($result) return 1;
else return 0;
}
?>
Once the AJAX request is working the next step is simply work around the code to send an e-mail to the person chosen if their e-mail address was entered - a bit stuck on how to do that as I want the e-mail field to remain optional.
Then obviously, I want to return the name of the person that was picked at random and that will be it!
Thanks,

Use Firebug for Firefox, or watch the console in Chrome/Safari. So you would have seen that you have a javascript error:
Uncaught ReferenceError: comment is not defined
So the script:
//cancel the submit button default behaviours
return false;
isn't executed and the form is posted normally.
