Facebook Comment Box URL Problem


When a website URL is clicked from Facebook (usually the News Feed) linking to the respective page with the comment box, Facebook attaches a query string to the URL.

The Comment Box then uses this entire URL (including the query string), and assumes that the address is an entirely different page, thus doesn't display existing comments for that page. To compound the issue, if people comment on the URL with the query string, their comments are only displayed at that queried URL, and not on the actual page.

Live example:
FB Query String:

From what I can tell, this is also the case with the 'Like' button also.

Like button seems alright, but this is indeed a problem. How nice of FB to include that piece in the url... I'll do something about that.

Could you try the latest source? It includes a fix for this.
BTW are you using Content Widgets to attach comments to pages?

I'll install the latest now.

Yes, I have am using a widget to attach the comments.

Okay, the update has broken it!

The provided URL to the widget is just missing the site domain; but otherwise, the URL provided to it doesn't include the query string, so it's almost there.


I need to roll my site back as it's live.

Oh, see attached file (why didn't it attach the file to my comment?) sigh

Okay, I've determined that it's definitely also affecting the Like button. See my attached screen shots.

Thank you!

Won't let me attach files without a comment...

That cleared things up regarding the like button. It uses the same, wrong url that has the facebook_comment_id param. The best solution here IMO would be to do a redirect from an action filter to the original url. What do you think?

I've added a redirecting filter, please see if it works for you. It really should this time.
