Call Event Calendar 3 in WPMS from a different site ID

I’ve been working on a pretty complicated WordPress Multi-Site project for the College of Education at UGA. One of their sites will be controlling the master calendar for the main website. We wanted to display the calendar from the sub-site. One the main site of the page (an possibly on other sub-sites).

Generally speaking, in WPMS / WPMU you can get the content of one site by switching to that site ID using the switch_to_blog($id) function. However, this does not work with Event Calendar 3, because of the way it builds it’s global $ec3 variable.

The problem is, when you are on site id 1, the $ec3 creates a variable that points to the schedule table for site id 1. Even if you run switch_to_blog(2), $ec3 still tries to get the schedule from site id 1. So it was returning an empty calendar. The easiest way to fix this (until EC3 updates their code) was to re-instantiate the global $ec3 variable. Basically this is what I did:

This re-instantiates the $ec3 variable for the schedule I needed to get from that specific site ID. It should be a fairly simple fix for EC3. Until then, this is the easiest fix if you need to do what I’m doing.
