If you’ve ever tried to use the native Facebook share functionality to share a specific tab on a Facebook fan page, you’ve realized that Facebook handles page tabs differently than external content, overriding the IFRAME tab’s Open Graph meta data with content from the fan page itself.
In a previous post, we showed you the CSS necessary to make custom Share link in an FBML app or application tab. Since FBML is being deprecated, this obviously won’t work anymore.
In a previous post, I explained how to use an FQL query to get the current number of “likes” for a page, even if that page is age-gated. This time we’re going to look at the FQL query to do something similar for external pages (content pages not on Facebook, like blog posts, etc.)
