当用户使用Facebook SDK for JavaScript在Facebook上分享帖子时，如何更新mysql中的数据

Question

I want to update my database when user share post on fb. I am using Facebook SDK for JAVASCRIPT.

My Code Is:-

   <script>
        document.getElementById('shareBtn').onclick = function() {
          FB.ui({
            method: 'share',
            display: 'popup',
            href: 'url goes here',
          }, function(response){
              if (response && response.post_id) {
                      //ajax code goes here for database update
                    } else {
                      alert('oops post was not published');
                    }
          });
        }
        </script>

Button Code-

    <div class="fb-share-button" 
    data-href="url goes here" 
    data-layout="button" data-size="large">
    </div>

I am able to share the post but how to update the mysql data when user successfully sharesthe post

Answer 1

You will only know if the user shared something if you authorize the user with the publish_actions permission. That permission needs to get reviewed by Facebook, and Facebook will not approve it just for this, i´m afraid.

In other words: It is not possible.
