PHP - MySQL: Synchronize two calendars - php

Question

I'm using a plugin for calendar bookings and reservations. I can create more calendars, but I can't set different services, prices and payment methods in one calendar.
I need two different services for the same event, so I should create two calendars, but in this case there isn't a synchronization of booking days between the calendars: I need one calendar only.
So my intention is to synchronize both the calendars via PHP and MySQL. This plugin create a specific table called "days" in the calendar db for date, like this:
| Calendar Id | Day | Month | Year |
| 01 | 01 monday available | 01 | 2014 |
| 01 | 02 tuesday available | 01 | 2014 |
| 01 | 03 wednesday booked | 01 | 2014 |
| 02 | 01 monday in pending | 01 | 2014 |
| 02 | 02 tuesday booked | 01 | 2014 |
| 02 | 03 wednesday available | 01 | 2014 |
How can I synchronize data (day, month, year) of calendar id 01 and calendar id 02?
I've found this:
How can i synchronize two database tables with PHP?
But I need to syncronize data (records) and not tables or databases.
I hope that my questione is clair, sorry for my English and thanks in advance!

Answer 1

You should create a new column to store if is available.
| Calendar Id | Day | Month | Year | Available
Then, you can use a trigger:
CREATE TRIGGER synchronize_update BEFORE UPDATE ON table
FOR EACH ROW BEGIN
UPDATE table SET Available = NEW.Available WHERE calendar_id <> NEW.calendar_id AND Day = New.Day And Month = NEW.Month AND Year = NEW.Year;
END;
