Simple and Cool jQuery CAPTCHA Plugin - Real Person

Simply create a form as you normally would and include a text field to use for the real person verification. In this example, my field would have a class of "your-captcha".

<script type="text/javascript">
$(function() {

So after you have the front-end working, we need to verify that the code entered was correct. Use this:

function rpHash($value) { 
    $hash = 5381; 
    $value = strtoupper($value); 
    for($i = 0; $i < strlen($value); $i++) { 
        $hash = (($hash << 5) + $hash) + ord(substr($value, $i)); 
    return $hash; 
if (rpHash($_POST['realPerson']) == $_POST['realPersonHash']) {
