This took me a while, and it is probably not a widely used CMS or framework but here it is anyways.
Apply the code to your footer file
Mine is:
/app/views/themed/(themename)/elements/footer.ctp (if themed)
/app/views/elements/footer.ctp (if standard)
Add this code before the </div> tags
<!-- Woopra Code Start -->
<script type="text/javascript">
var woopra_array = new Array();
woopra_array['name'] = '<?php echo $session->read('Auth.User.username'); ?>';
</script>
<script type="text/javascript">
var _wh = ((document.location.protocol=='https:') ? "https://sec1.woopra.com" : "http://static.woopra.com");
document.write(unescape("%3Cscript src='" + _wh + "/js/woopra.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<!-- Woopra Code End -->
Where it reads "Auth.User.username" that should be your variable
Yours could be "username" or "user" or something similar.
