title: Post to facebook wall using API Graph and missing share button
body: <p>Is it possible to post a message with share button in Graph API. I use SDK-PHP v3 and this code:</p>
  
  <pre><code>    $args = array(
          'access_token' =&gt; TOKEN_HERE,
          'message'   =&gt; 'message here',
          'link'      =&gt; 'http://www.example.com/',
          'caption'   =&gt; 'caption here'
      );
      $result = $facebook-&gt;api("/me/feed", "post", $args);
  </code></pre>
  
  <p>It works fine but share button is missing. There is a comment and like button but no SHARE button. Please do not give me any links to tutorials or fecebook documentation. If you know how to do this or you know it's not possible just write it. Thanks!</p>
