Is there a way to accomplish these 2 simple things:
Hide the "Like" button when the user opted to "Like" it.
On page load, check if the user "Like"s the page. If TRUE, hide the "Like" button. If FALSE, show it.
The second thing you want to do is easy to do:
FB.Event.subscribe('edge.remove', function(href, widget) {
// run some jQuery to hide a div that holds the like button
});
the first has been breaking my balls for the last 48 hours, but I'm there now.
(Edit: I'm very new to this myself, so take in mind my ignorance and limited understanding) What you need to know though is that a facebook user must give you permission for you to know whether he or she is fan-of/likes your page. This means you must create a FB application and link it to your page. Upon loading/liking the user will be asked for permission to share his basic information. For a simple hide of a 'like button' this seems excesive. If you're interested though, I can tell you more about this.
