title: 2 way sync Google Calendar with Fullcalendar
body: <p>I've been able to programmatically develop a 2 way sync between my Fullcalendar and my Google Calendar using php and javascript.  My fullcalendar displays events from a Mysql database as well as events from Google calendar. 
  The problem I am having is that my when my mysql fullcalendar events load into my Google calendar, I then see the mysql events 2x on my fullcalendar...one from mysql and then the one coming back from Google.  I need to continue displaying the event created by mysql and discontinue displaying the google events....but only the google events that originated from mysql.  </p>
  
  <p>In essense I need to filter out the Google Calendar events that originated from my database, but display google calendar events that were entered manually into the Google Calendar.</p>
  
  <p>When I send the mysql events to google, I currentlty store the returned google calendar id, $gcal_id = $createdEvent->getId() into mysql.  My intent is to read the google api callback and filter out the gCal$uid's that match the id's I stored in mysql.</p>
  
  <p>I cannot figure out how to access the gCal$uid values found in the google api callback, and then compare them to an array of id's pulled from the database.</p>
  
  <p>Any ideas or code snippets would be greatly appreciated.</p>
  
  <p>Thank you.</p>
