     This is the code i get from facebook developer

            <div id="fb-root"></div>
       <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_US/all.js#xfbml=1&appId=657379467662635";
         fjs.parentNode.insertBefore(js, fjs);
          }(document, 'script', 'facebook-jssdk'));</script>


         <fb:like href="https://developers.facebook.com/docs/plugins/"    layout="standard" action="like" show_faces="true" share="true"></fb:like>

Answer 1

That's because you output html entities (like "<") in your theme function instead of actual HTML code. Replace everything in the "$output" variable with the code you got from facebook developer like this :

$output ='<div id ... share="true"></fb:like>';

instead of

$output ='<div id= ... share="true"></fb:like>';
