On my old selling site when an order was completed the data is put into a serialized array. On the ‘new client’ page of the admin site I have a drop down of the clients who have completed an order.

JSON = (JavaScript object notation) a lightweight data-interchange format. XML = (Extensible Markup Language) a heavyweight data-interchange format. AJAX = (asynchronous JavaScript and XML) AJAJ = (asynchronous JavaScript and JSON) Recently I had to work with data in the form of JSON being sent back from an AJAX call to the server.
