3 * Name: Facebook Connector
5 * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>
9 * Installing the Friendica/Facebook connector
11 * 1. register an API key for your site from developer.facebook.com
12 * a. We'd be very happy if you include "Friendica" in the application name
13 * to increase name recognition. The Friendica icons are also present
14 * in the images directory and may be uploaded as a Facebook app icon.
15 * Use images/friendica-16.jpg for the Icon and images/friendica-128.jpg for the Logo.
16 * b. The url should be your site URL with a trailing slash.
17 * Friendica is a software application and does not require a Privacy Policy
18 * or Terms of Service, though your installation of it might. Facebook may require
19 * that you provide a Privacy Policy, which we find ironic.
20 * c. Set the following values in your .htconfig.php file
21 * $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
22 * $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
23 * Replace with the settings Facebook gives you.
24 * d. Navigate to Set Web->Site URL & Domain -> Website Settings. Set
25 * Site URL to yoursubdomain.yourdomain.com. Set Site Domain to your
27 * 2. Enable the facebook plugin by including it in .htconfig.php - e.g.
28 * $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
29 * 3. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
30 * and click 'Install Facebook Connector'.
31 * 4. This will ask you to login to Facebook and grant permission to the
32 * plugin to do its stuff. Allow it to do so.
33 * 5. You're done. To turn it off visit the Plugin Settings page again and
34 * 'Remove Facebook posting'.
36 * Vidoes and embeds will not be posted if there is no other content. Links
37 * and images will be converted to a format suitable for the Facebook API and
38 * long posts truncated - with a link to view the full post.
40 * Facebook contacts will not be able to view private photos, as they are not able to
41 * authenticate to your site to establish identity. We will address this
42 * in a future release.
