10 * Installing the Friendica/Facebook connector
12 * 1. register an API key for your site from developer.facebook.com
13 * a. We'd be very happy if you include "Friendica" in the application name
14 * to increase name recognition. The Friendica icons are also present
15 * in the images directory and may be uploaded as a Facebook app icon.
16 * Use images/friendica-16.jpg for the Icon and images/friendica-128.jpg for the Logo.
17 * b. The url should be your site URL with a trailing slash.
18 * Friendica is a software application and does not require a Privacy Policy
19 * or Terms of Service, though your installation of it might. Facebook may require
20 * that you provide a Privacy Policy, which we find ironic.
21 * c. Set the following values in your .htconfig.php file
22 * $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
23 * $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
24 * Replace with the settings Facebook gives you.
25 * d. Navigate to Set Web->Site URL & Domain -> Website Settings. Set
26 * Site URL to yoursubdomain.yourdomain.com. Set Site Domain to your
28 * 2. (This step is now obsolete. Enable the plugin via the Admin panel.)
29 * Enable the facebook plugin by including it in .htconfig.php - e.g.
30 * $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
31 * 3. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
32 * and click 'Install Facebook Connector'.
33 * 4. This will ask you to login to Facebook and grant permission to the
34 * plugin to do its stuff. Allow it to do so.
35 * 5. Optional step: If you want to use Facebook Real Time Updates (so new messages
36 * and new contacts are added ~1min after they are postet / added on FB), go to
37 * Settings -> plugins -> facebook and press the "Activate Real-Time Updates"-button.
38 * 6. You're done. To turn it off visit the Plugin Settings page again and
39 * 'Remove Facebook posting'.
41 * Vidoes and embeds will not be posted if there is no other content. Links
42 * and images will be converted to a format suitable for the Facebook API and
43 * long posts truncated - with a link to view the full post.
45 * Facebook contacts will not be able to view private photos, as they are not able to
46 * authenticate to your site to establish identity. We will address this
47 * in a future release.
51 * - Implement a method for the administrator to delete all configuration data the plugin has created,
52 * e.g. the app_access_token
53 * - Implement a configuration option to set the polling interval system-wide
