A simple plugin to Sync Facebook events to The Events Calendar plugin by Modern Tribe.
|
||||
|
||||
== Description ==
|
||||
|
||||
A simple plugin to Sync Facebook events to The Events Calendar plugin by Modern Tribe.
|
||||
|
||||
Get The Events Calendar plugin:
|
||||
http://wordpress.org/extend/plugins/the-events-calendar/
|
||||
|
||||
== Installation ==
|
||||
|
||||
1. Download the plugin archive and expand it
|
||||
2. Upload the sync-facebook-events folder to your /wp-content/plugins/ directory
|
||||
3. Go to the plugins page and click 'Activate' for Sync FB Events
|
||||
4. Navigate to the Settings section within Wordpress and enter your Facebook App ID, App Secret & UID.
|
||||
5. Ensure The Events Calendar plugin is installed and configured - http://wordpress.org/extend/plugins/the-events-calendar/
|
||||
5. Press 'Update' to synchronize your current Facebook events for display within The Events Calendar.
|
||||
6. Synchronization will continue to occur on the schedule you set. You can always update manually if/when needed.
|
||||
|
||||
== Frequently Asked Questions ==
|
||||
|
||||
Q: What is the Facebook App ID and App Secret, and why are they required?
|
||||
|
||||
A: The Facebook App ID and App Secret are required by Facebook to access data via the Facebook graph API.
|
||||
To signup for a developer account or learn more see - http://developers.facebook.com/docs/guides/canvas/
|
||||
|
||||
Q: How do I find the Facebook UID of the page for which I wish to synchronize events?
|
||||
|
||||
A: Goto the page you're interested in - ex. https://www.facebook.com/webtrends
|
||||
Copy the URL and replace 'www' with 'graph' - ex. https://graph.facebook.com/webtrends
|
||||
The UID is the first item in the resulting text. In this example it is "54905721286".
|
||||
|
||||
Q: Do my Facebook events get updated on a schedule?
|
||||
|
||||
A: Yes, You can choose the update interval and also update immediately when you press the 'Update' button from the Sync FB Events section within settings.
|
||||
|
||||
Q: Why do I get a blank screen when running an update?
|
||||
|
||||
A: Check your Facebook App ID, Facebook App Secret and Facebook UID. One of them is probably incorrect.
|
||||
|
||||
Q: Why doesn't Modern Tribe just provide this functionality within their own plugin?
|
||||
|
||||
A: They incorporated this one, actually.
