WP-FacebookConnect

Description

WP-FacebookConnect adds Facebook functionality to WordPress using the
Facebook Connect APIs. Features include:

  • Single-signon with your Facebook account
  • Publish comments to the newsfeed
  • Comment avatars display Facebook profile photos

What’s New:

1.3
– Add a “Like” button to posts
– No longer set user_email because it no longer works, and overwrites
user-entered addresses

1.2
– Template bundles have been replaced with the stream.publish API.
Any template customizations will need to be updated for this API.

Upgrades

Please see the CHANGES file for information that may be useful when
upgrading from an older release.

A note on ‘nofollow’

When a Facebook Connect user posts a comment the author field of the
comment will link back to that user’s public profile page at Facebook.
For instance, my comments link back to
http://www.facebook.com/people/Adam-Hupp/806285106.

To reduce spamming WordPress automatically adds the nofollow attribute
to all comment links, but this is undesirable when the links are
generated by a trusted source (e.g the plugin). For this reason the
plugin will remove the nofollow attribute from all Facebook user
comments. This is configurable on the Settings page.

Known Problems

  1. The login status box (“Welcome, youname”) has a fixed size instead
    of expanding to fit the name.

Future Work

  1. Support avatars and newsfeed for blog posters.
  2. Notification when a friend comments on the same article you have.
  3. Widget to display your friends that have visited the blog.
  4. Widget to invite friends to read the article.

How Does it Work?

The first time a user selects the “Connect” button the plugin will
create a new wordpress user named ‘fbN’, where N is a Facebook user
id. The Facebook user id is also stored in the wp_usermeta table
under the key ‘fbuid’. The plugin can securely identify the Facebook
user because it recieved signed session cookies along with the
request.

Once the WordPress and Facebook account are linked and the Facebook
userid is verified the plugin sets a WordPress login cookie. The page
reloads and at this point the user will be logged into the blog.

Most login state handling occurs in fbc_init_auth.

Installation

  1. Copy the plugin to wp-content/plugins/wp-fbconnect under the
    Wordpress installation.

    1. In the WordPress Admin panel, visit the plugins page and Activate the plugin.
    2. Visit the settings page and select “Facebook Connect”. Follow the
      given instructions to configure the plugin and obtain a Facebook API key.

A minimal amount of theme integration is necessary. Open the
‘comment.php’ file in the theme and add the following line where the
Connect login button should be inserted:

  <?php do_action('fbc_display_login_button') ?> 

The reason for calling fbc_comment_login via do_action instead of
directly is to avoid spewing errors if the plugin is disabled. It
would be equally correct to directly call fbc_comment_login() here.

As a simple example, the comments.php file on my blog looks like:

<?php if ( $user_ID ) : ?>  

….

`

Note that the fbc_comment_login function should be called regardless
of whether the user is currently logged into WP or not. It will DTRT.

See config.php and the Settings page for more configuration and
customization options.
