title: CodeIgniter - User Tracking
body: <p>I have started a Facebook marketing campaign for website and web on Codeigniter, show advertise on Facebook, so when you click it will redirect to website directly. </p>
  
  <p>Now I need to save data of users like, number of users coming from Facebook refer URL. 
  For this reason I Google'd and found this <a href="https://code.google.com/p/ci-usertracking/" rel="nofollow">link</a>, but I don't know how to implement this in web. I even read the installation way, but I think I'm making some mistake. </p>
