You're probably having problems because the jQuery jQuery.getJSON()
method uses a GET request (the clue's in the method name) to return
JSON data to your javascript, not to POST JSON data to your back-end.
For that, you'd want to use the more generic jQuery.ajax() method,
kinda like this:
var postData['data[Model][field]'] = 'value';
$.ajax({
type: 'POST',
dataType: 'json',
url: '/locations/find',
data: postData,
success: function(result) {
// do something with the result object
}
});
The data should be available in your controller as $this->data['Model']
['field'] - it won't be JSON, as there's no need for it to be. The
javascript will expect JSON data back though.
