One of the things Facebook Tab Manager is used for is to create “reveal tabs” or “gate tabs” where the user has to “Like” the page before they can see some exclusive content. The super-special content serves as the attraction to build your base of “likes” or “fans” – subscribers to your updates.
The plugin supports two methods, using shortcodes or the Reveal Tab Setup utility described here.
The advantage of the Reveal Tab Setup method is you don’t have to clutter your posts with code. You create two clean posts, and designate one to be viewed by page fans and another to be shown to newcomers. The URL you register with Facebook uses a query string in the format
?fbreveal=100-200 where 100 is the ID of a post to be shown to the new people and 200 is the post for fans.
The Reveal Tab Setup utility helps you construct this URL, which can also include a number of other options such as specifying that links should be opened in a new window. In addition to Facebook tabs, the utility lets you select existing blog posts and page tabs, which will be displayed in the Facebook template rather than your website’s default template.
One potential advantage of this approach is performance. Instead of loading a base post and then looking up additional content based on shortcode parameters, this method avoids some of the default WordPress processing and cuts straight to loading the fan or non-fan content (translation for programmers: the action for detecting a URL in this format is called on “init” before most of the normal database queries run).
When you select a Facebook Tab posts to include, it will be displayed with the filter options you specified in the Options panel of the post. If you select an ordinary page or post, use the checkbox options specified here to set broad options. Selecting “Minimize the_content filters” specifies that only a minimum set of WordPress options should be executed on the main content of the post (preventing effects intended for regular WordPress posts, such as the output of social media sharing icons).
