title: Use jQuery to update database through Joomla MVC component
body: <p>I am developing a new version of my Joomla component TTVideo. I'm trying setup a rating system using the jQuery stars plugin. I have the jQuery noconflict issue resolved, however I'm a bit confused as to how to send the vote <strong>securely</strong> to a helper class that updates the database with the value of the vote. </p>
  
  <p>Usually this is done through an external script which is only every accessed by the ajax request. I would like to do this so it is incorporated within my component, and in such a fashion that the std Joomla variables are available to the helper class e.g. getDBO() and the database reference #__table_name.</p>
  
  <p>Any comments on how to achieve this will be greatly appreciated. Thanks.</p>
