/**
|
|
* Installing the Friendica/Facebook connector
|
|
*
|
|
* 1. register an API key for your site from developer.facebook.com
|
|
* a. We'd be very happy if you include "Friendica" in the application name
|
|
* to increase name recognition. The Friendica icons are also present
|
|
* in the images directory and may be uploaded as a Facebook app icon.
|
|
* Use images/friendica-16.jpg for the Icon and images/friendica-128.jpg for the Logo.
|
|
* b. The url should be your site URL with a trailing slash.
|
|
* Friendica is a software application and does not require a Privacy Policy
|
|
* or Terms of Service, though your installation of it might. Facebook may require
|
|
* that you provide a Privacy Policy, which we find ironic.
|
|
* c. Set the following values in your .htconfig.php file
|
|
* $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
|
|
* $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
|
|
* Replace with the settings Facebook gives you.
|
|
* d. Navigate to Set Web->Site URL & Domain -> Website Settings. Set
|
|
* Site URL to yoursubdomain.yourdomain.com. Set Site Domain to your
|
|
* yourdomain.com.
|
|
* 2. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
|
|
* and click 'Install Facebook Connector'.
|
|
* 3. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
|
|
* and click 'Install Facebook Connector'.
|
|
* 4. This will ask you to login to Facebook and grant permission to the
|
|
* plugin to do its stuff. Allow it to do so.
|
|
* 5. Optional step: If you want to use Facebook Real Time Updates (so new messages
|
|
* and new contacts are added ~1min after they are postet / added on FB), go to
|
|
* Settings -> plugins -> facebook and press the "Activate Real-Time Updates"-button.
|
|
* 6. You're done. To turn it off visit the Plugin Settings page again and
|
|
* 'Remove Facebook posting'.
|
|
*
|
|
* Vidoes and embeds will not be posted if there is no other content. Links
|
|
* and images will be converted to a format suitable for the Facebook API and
|
|
* long posts truncated - with a link to view the full post.
|
|
*
|
|
* Facebook contacts will not be able to view private photos, as they are not able to
|
|
* authenticate to your site to establish identity. We will address this
|
|
* in a future release.
|
