3 * Name: Facebook Connector
5 * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>
9 * Installing the Friendika/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 "Friendika" in the application name
13 * to increase name recognition. The Friendika icons are also present
14 * in the images directory and may be uploaded as a Facebook app icon.
15 * Use images/friendika-16.jpg for the Icon and images/friendika-128.jpg for the Logo.
16 * b. The url should be your site URL with a trailing slash.
17 * You may use http://portal.friendika.com/privacy as the privacy policy
18 * URL unless your site has different requirements, and
19 * http://portal.friendika.com as the Terms of Service URL unless
20 * you have different requirements. (Friendika is a software application
21 * and does not require Terms of Service, though your installation of it might).
22 * c. Set the following values in your .htconfig.php file
23 * $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
24 * $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
25 * Replace with the settings Facebook gives you.
26 * d. Navigate to Set Web->Site URL & Domain -> Website Settings. Set
27 * Site URL to yoursubdomain.yourdomain.com. Set Site Domain to your
29 * 2. 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. You're done. To turn it off visit the Plugin Settings page again and
36 * 'Remove Facebook posting'.
38 * Vidoes and embeds will not be posted if there is no other content. Links
39 * and images will be converted to a format suitable for the Facebook API and
40 * long posts truncated - with a link to view the full post.
42 * Facebook contacts will not be able to view private photos, as they are not able to
43 * authenticate to your site to establish identity. We will address this
44 * in a future release.
