[Plugin: Events Manager] Save Booking

I’m trying to save a booking. I called save() on the EM_BOOKING object and it entered the data into the bookings table, but not in the tickets_bookings table which seem to mess things up a bit.

I set the status, booking and comment then save. What am I missing?

example

$EM_BOOKING->booking_status = “1”;
$EM_BOOKING->booking_spaces = “1”;
$EM_BOOKING->booking_comment = “hello”;
$EM_BOOKING->save();
