Acessing likes on comments an videos in facebook

Can anyone suggest how to track the comments and other objects (videos,photos,etc) which a user likes in facebook? Assuming 开发者_如何学JAVAthat the user has registerd to my application.

You can use FQL with the like table. http://developers.facebook.com/docs/reference/fql/like/ Reference includes examples.

But you can't get a list pf everything the user likes. If you know what object you want to track you can also use the link_stat table: http://developers.facebook.com/docs/reference/fql/link_stat/
