title: Encode Store Data as JSON String in Sencha Touch
body: <p>I'm trying to make a simple Sencha Touch App that submits a form with attached images, and stores the data in a remote MySQL database via PHP.</p>
  
  <p>The user-inserted images are stored in a data store.</p>
  
  <p>When the user clicks the submit button, I would like all the data in the store to be encoded into a JSON string which I can easily send to my database.</p>
  
  <p>Is there any way to do this in Sencha Touch?</p>
  
  <p>Thanks!</p>
