fullcalendar - send POST data to json_events.php

fullcalendar - send POST data to json_events.php

 
Using fullcalendar - arshaw.com/fullcalendar/
I imagine this is simple but I can't quite get the concept clear.
Basically I am working on loading events on the month prev/next click
I have been trying:

viewDisplay: function(view) { var next = view.title; }, //alert(next);

which gives me "November 2012"
split this in two, then ...

events: { 
url: 'json-events.php',
type: 'POST', <br/>
data: { month: month,
year: year } },




How to read the POST val in json-events.php (which builds the event array)?
Assuming I am on the right track here. [super newbie]
I am not sure if this is a fullcalendar specific or jquery general question.

Thanks
