title: Netflix-style tooltip with AJAX, Jquery, PHP and MySQL
body: <p>I've got a large PHP/MySQL-driven website and I'd like to add Netflix-style tooltips to it.</p>
  
  <p>What I'd like it to do is:</p>
  
  <ol>
  <li>User clicks on a link</li>
  <li>Variable passed to external file using AJAX</li>
  <li>External file uses variable to query MySQL database</li>
  <li>Query result appears in tooltip</li>
  </ol>
  
  <p>A wrinkle is that there are multiple types of links of the page. Some would select one table, others would select other tables.</p>
  
  <p>Does anyone know of a tutorial online that I could use to learn how to create this?</p>
