title: CakePHP: creating my own functions
body: <p>I have an Article controller &amp; model. I want to have a function that adds one to an integer when a link is clicked. So I have say a "i like" button (link) it takes me to Articles/thumbsup it will then take the thumbsup field of that article and increment it by one, then save the article, and redirect to the view. </p>
  
  <p>I'm not sure how to modify records in this way. I need to load the article, modify the data and then save it. </p>
  
  <p>My hope is that this be handled by javascript so noone will see the url change.</p>
  
  <p>Can someone help me out here?</p>
  
  <p>Thanks,</p>
