How to redirect a form T(to a Home Page)after submit

Hello. am really new to php. and i need to redirect a simple php form to home page, after submit the form. the code of the form is as follow:


<?php


$yourEmail = "soapmaster@jabonesvioleta.com"; // the email address you wish to receive these mails through
$yourWebsite = "http://www.jabonesvioleta.com"; // the name of your website

$maxPoints = 4; // max points a person can hit before it refuses to submit - recommend 4


// DO NOT EDIT BELOW HERE

$error_msg = null;
$result = null;

function isBot() {
$bots = array("Indy", "Blaiz", "Java", "libwww-perl", "Python", "OutfoxBot", "User-Agent", "PycURL", "AlphaServer", "T8Abot", "Syntryx", "WinHttp", "WebBandit", "nicebot");

$isBot = false;
foreach ($bots as $bot)
if (strpos($_SERVER['HTTP_USER_AGENT'], $bot) !== false)

$isBot = true;

exit("Bots not allowed.</p>");
}

if ($_SERVER['REQUEST_METHOD'] == "POST") {
function clean($data) {
$data = trim(stripslashes(strip_tags($data)));
return $data;
}

// lets check a few things - not enough to trigger an error on their own, but worth assigning a spam score..
// score quickly adds up therefore allowing genuine users with 'accidental' score through but cutting out real spam :)
$points = (int)0;

Well if you are happy with the way the form functions and looks then all you need is to assign the $thanksPage variable to where ever you want to redirect to. The code already takes this variable into consideration and will redirect if the variable has a value.
So put this at the top of the script after the opening php tag -

PHP Code:

---

$thanksPage = "http://yourdomain.com/yourpage.php"; 


---

obviously change the yourdomain and yourpage to the actual info of your site.
