A Trackback can be sent from any of your controller functions using code
similar to this example::
- $this->load->library('trackback'); $tb_data = array( 'ping_url' => 'http://example.com/trackback/456', 'url' => 'http://www.my-example.com/blog/entry/123', 'title' => 'The Title of My Entry', 'excerpt' => 'The entry content.', 'blog_name' => 'My Blog Name', 'charset' => 'utf-8' ); if ( ! $this->trackback->send($tb_data)) { echo $this->trackback->display_errors(); } else { echo 'Trackback was sent!'; }

==========================
Before you can receive Trackbacks you must create a table in which to
-store them. Here is a basic prototype for such a table:

The Trackback specification only requires four pieces of information to
be sent in a Trackback (url, title, excerpt, blog_name), but to make
the data more useful we've added a few more fields in the above table
