I uploaded this plugin to Subversion this morning without any screenshots or much documentation, and it’s already been downloaded 250 times…

What it does? Adds “Like” buttons to your Posts / Pages / Custom Post Types so you can create a circular traffic vortex between Your Blog and the ‘book.

Use these functions in your theme:

// in the Loop - for posts / pages / custom post types
the_like_button()

// a Like button for your blog / website, put it anywhere!
the_blog_like_button()

// use this if you don't want to register your app
the_like_iframe()


Although the JavaScript init function that loads Facebook’s API asks for an APP ID, I think you can get away without having one if you are only going to use the Like buttons and not add any Facebook Connect features.

This is a beta release but should work just fine. Enjoy.
