title: ExtJs add, delete, update row to the grid
body: <p>I need to enable the user to add a new row to the grid.
  The user may also update one or more rows.</p>
  
  <p>What is the best way to do this?</p>
  
  <p>I have <a href="http://pssnet.com/~devone/dnc/dncEditProducts.php" rel="nofollow noreferrer">tried</a> to use <a href="http://www.extjs.com/deploy/dev/examples/restful/restful.html" rel="nofollow noreferrer">RESTful Store Example</a>, but have not been able to handle the REST posting with php.  </p>
  
  <p>When the add record button is clicked, it fires the POST twice (once upon clicking, and once when pressing the update).  </p>
  
  <p>Also, the updates are kept marked, even after posting to the db.</p>
  
  <p>Thank you.</p>
