Drupal for Facebook ------------------- More information: http://www.drupalforfacebook.org, http://drupal.org/project/fb Primary author and maintainer: Dave Cohen (http://www.dave-cohen.com/contact) Do NOT contact the maintainer with a question that can be easily answered with a web search. You may not receive a reply. Branch: 6.x-3.x (version 3.x for Drupal 6.x) This file is more current than online documentation. When in doubt, trust this file. Online documentation: http://drupal.org/node/195035, has more detail and you should read it next.. To upgrade: - Read the upgrade instructions: http://drupal.org/node/936958 To install: - Make sure you have a PHP client from facebook (version < 3.0.0). The 3.0.0 or higher versions are not supported by this version of Drupal for Facebook. Download from http://github.com/facebook/php-sdk. Extract the files, and place them in sites/all/libraries/facebook-php-sdk. If you have the Libraries API module installed, you may place the files in another recognised location (such as sites/all/libraries), providing that the directory is named 'facebook-php-sdk'. Or, to manually set the location of the php-sdk in any other directory, edit your settings.php to include a line similar to this (add to the section where the $conf variable is defined, or the very end of settings.php. And customize the path as needed.): $conf['fb_api_file'] = 'sites/all/libraries/facebook-php-sdk/src/facebook.php'; See also http://drupal.org/node/923804 - Your theme needs the following attribute at the end of the tag: xmlns:fb="http://www.facebook.com/2008/fbml" Typically, this means editing your theme's page.tpl.php file. See http://www.drupalforfacebook.org/node/1106. Note this applies to themes used for Facebook Connect, iframe Canvas Pages, and Social Plugins (i.e. like buttons). Without this attribute, IE will fail. - To support canvas pages and/or page tabs, url rewriting and other settings must be initialized before modules are loaded, so you must add this code to your settings.php. This is done by adding these two lines to the end of sites/default/settings.php (or sites/YOUR_DOMAIN/settings.php). include "sites/all/modules/fb/fb_url_rewrite.inc"; include "sites/all/modules/fb/fb_settings.inc"; (Change include paths if modules/fb is not in sites/all.) - Also for canvas pages, see http://drupal.org/node/933994 and search for "P3P" to avoid a common problem on IE. - Go to Administer >> Site Building >> Modules and enable the Facebook modules that you need. Enable fb.module for Social Plugins. Enable fb_devel.module and keep it enabled until you have everything set up. You should disable this on your live server once you are certain facebook features are working. (Note this requires http://drupal.org/project/devel, which is well worth installing anyway.) Enable fb_app.module and fb_user.module if you plan to create facebook applications. Enable fb_connect.module for Facebook Connect and/or fb_canvas.module for Canvas Page apps. Pages at http://drupal.org/node/932690 will help you decide which other modules you need to enable for your particular needs. To support Facebook Connect, Canvas Pages, and/or Social Plugins that require an Application, read on... - You must enable clean URLs. If you don't, some links that drupal creates will not work properly on canvas pages. - Create an application on Facebook, currently at http://www.facebook.com/developers/editapp.php?new. Fill in the minimum required to get an apikey and secret. If supporting canvas pages, specify a canvas name, too. You may ignore other settings for now. - Go to Administer >> Site Building >> Facebook Applications and click the Add Applicaiton tab. Use the app id, apikey and secret that Facebook has shown you. Hopefully other settings will be self-explanitory. When you submit your changes, Drupal for Facebook will automatically set the callback URL and some other properties which help it work properly. Troubleshooting: --------------- Reread this file and follow instructions carefully. Read http://drupal.org/node/933994, and all the module documentation on http://drupal.org/node/912614. Enable the fb_devel.module and add the block it provides (called "Facebook Devel Page info") to the footer of your Facebook theme. fb_devel.module will catch some errors and write useful information to Drupal's log and status page. Disable Global Redirect, if you have that module installed. Users have reported problems with it and Drupal for Facebook. Any module which implements custom url rewrites could interfere with canvas page and profile tab support. Bug reports and feature requests may be submitted. Here's an idea: check the issue queue before you submit http://drupal.org/project/issues/fb If you do submit an issue, start the description with "I read the README.txt from start to finish," and you will get a faster, more thoughtful response. Seriously, prove that you read this far. Below are more options for your settings.php. Add the PHP shown below to the very end of your settings.php, and modify the paths accordingly (i.e. where this example has "sites/all/modules/fb", you might need "profiles/custom/modules/fb"). //// Code to add to settings.php: ///////////////////////////////// /** * Drupal for Facebook settings. */ if (!is_array($conf)) $conf = array(); $conf['fb_verbose'] = TRUE; // debug output //$conf['fb_verbose'] = 'extreme'; // for verbosity fetishists. // More efficient connect session discovery. // Required if supporting one connect app and different canvas apps. //$conf['fb_id'] = '123.....XYZ'; // Your connect app's ID goes here. // Enable URL rewriting (for canvas page apps). include "sites/all/modules/fb/fb_url_rewrite.inc"; include "sites/all/modules/fb/fb_settings.inc"; // end of settings.php
