Use Zend_Dojo_Data, which was built precisely for this purpose. :)
Simply do the following:
$data = new Zend_Dojo_Data('id', $object->fetchAll(), 'name');
echo $data;
I'm assuming that the "fetchAll()" you referenced in the earlier post
was a call to a database adapter or a Zend_Db_Table object; either way,
Zend_Dojo_Data is smart enough to figure it out.
As some background, the ComboBox and FilteringSelect widgets expect a
dojo.data payload in order to build the options for autocompletion.
dojo.data is an abstracted JSON data format used in Dojo for a variety
of widgets. Zend_Dojo_Data was created to create such structures.
