I'm trying to add Facebook comment box in each article by using following code. When I post comment to one article, it displays on all articles. I want to display different comments in different articles.
<script>(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_GB/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div align="center"> <div class="fb-comments" data-href="https://www.facebook.com/pages/sample" data-numposts="5" data-colorscheme="light"> </div> </div>
