Documentation ¶

The Linkback Extension consists of two parts: a Linkback server that accepts Linkback pings from remote clients, and a Linkback client that generates Linkback pings to remote servers.

Linkback Server ¶

The Linkback server consists of two parts, each separately configured:

• LinkbackAutoDiscovery – generates Pingback and TrackBack server auto-discovery code
• LinkbackController – implements the Pingback and TrackBack servers

LinkbackAutoDiscovery ¶

LinkbackAutoDiscovery generates the local Linkback server auto-discovery code and inserts it into posts. It is added as a filter to the controller action that displays posts.

LinkbackController ¶

LinkbackController implements the Pingback and TrackBack servers. It is configured using the CWebApplication::controllerMap property in the application's configuration file.

Linkback Client ¶

LinkbackClientBehavior ¶

LinkbackClientBehavior implements the Pingback and TrackBack clients. It is attached to the posts controller using the CController::behaviours() method; the LinkbackClientBehavior::linkback() method is called from the action that displays a post.

Please download the manual for full documentation on installation, usage, and the API.

Requirements ¶

• Yii 1.1.7 or above

Installation ¶

• Extract the release file under protected/extensions in the application or in your blogging module.
