Answer 1

<script>
  FB.Event.subscribe('edge.create', function(href, widget) {
    alert('You just liked the page!');
  });
</script>

Answer 2

window.fbAsyncInit = function () {

    FB.Event.subscribe('edge.create', function (response) {
        alert('Liked');
        });
    }
    );
    FB.Event.subscribe('edge.remove', function (response) {
        alert('DisLiked')
    });
};

(function (d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id))
        return;
    js = d.createElement(s);
    js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.7";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));

HTML:-

<div id="fb-root"></div><div class="fb-like" data-href="https://www.facebook.com/testpage" data-layout="standard" data-action="like" data-size="small" data-show-faces="true"></div>

Answer 3

so I simply rendered a unique like button for each logged in user with a URL of www.somewebsite.com/thisIsThePageIlike/facebookUID.

won't this defeat the purpose of having a like button and mess up your facebook search ranking? Every user will be liking a different url and so facebook will think you have a ton of pages each with a single like count.

I am also having an issue with XFBML like buttons where the edge.create event isn't firing

Answer 4

OK, so I can let you know how I implemented it. What I wanted to get was the UID of the facebook user clicking on the "Like" button inside my facebook connect app. I noticed when a user clicks on the "like" button, facebook fetches the URL passed to it from the button, so I simply rendered a unique like button for each logged in user with a URL of www.somewebsite.com/thisIsThePageIlike/facebookUID. When a request come to the web server with this url, it works like a callback and I process and record the UID if its the first time a user has clicked "like" (ie.. a record of this 'like' does not exist in the db). works for me.

Answer 5

It would be something like the one I have for my client's site such as

<iframe src="http://www.facebook.com/plugins/like.php?href=www.jesterkaraoke.com&amp;layout=standard&amp;show_faces=false&amp;width=450&amp;action=like&amp;colorscheme=light&amp;height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:35px;" allowTransparency="true"></iframe>
