I played around with the Json a little and realized that if I change the Json
to
{ identifier: 'id',
items:[{"id":"1","name":"XBox"},{"id":"2","name":"XBox
360"},{"id":"3","name":"Sony PSP"},{"id":"4","name":"Playstation
3"},{"id":"5","name":"Playstation 2"},{"id":"6","name":"PC
Games"},{"id":"7","name":"Nintendo
Wii"},{"id":"8","name":"GameCube"},{"id":"9","name":"Nintendo
DS"},{"id":"10","name":"Nintendo GBA"}]}
NOTE - I added the "{ identifier: 'id', items: .... }", saved that to a file
and read from that into my datastore for ComboBox, it works fine.
So how do I make Zend_Json to spit out Json with "{ identifier: 'id', items:
.... }" added?
