How to check if facebook button has been clicked?

Question

I put facebook as buttons on my Wordpress blog ... the idea is to use them as a kind of voting mechanism for posts. What I would like to do automatically adds a comment to the blog post every time someone “likes” it using the facebook button.

So my question is: does a similar api button provide some kind of callback to my page if someone “likes” something? - i.e. they didn’t like it yet, and they go through the process of sending it to facebook successfully.

Thanks for any help. Fyi I am very new to facebook api

, facebook-api:

JavaScript ():

FB.api({ method: 'pages.isFan', page_id: 'YOUR-PAGE-ID' }, function(resp) {
    if (resp) {
      alert('You like the Application.');
    } else {
      alert('You don't like the Application.');
    }
 });

PHP ( ):

$facebook = new Facebook(array(
    'appId' => 'YOUR-APP-ID',
    'secret' => 'YOUR-APP-SECRET-KEY',
));
$facebook->api(array(
                'method' => 'pages.isFan',
                'page_id' => 'YOUR-PAGE-KEY'
            ))

Remember that the REST-API (used in these examples) will be deprecated soon.
