How to link facebook comments widget to the current url?

Question

I've got a bit of a problem with facebook comments box on my website. I can't figue out a way for it to link the comments to the url they are on. For example a fb comment to Post 1 on my site is shared between all of my post wich can be a bit misleading for the users. I post about hundred posts a day (pics mainly), there's no way I can make a new box for each and every one of them.

Here's the piece of code that's troubling me:

<div class="fb-comments" data-href="funshit.ru" data-num-posts="5" data-width="530" data-colorscheme="dark"></div>

If only there was a way to make it link to the current url the problem'd be solved.

Any help is appreciated m8s.

Answer 1

Because the CMS I was coding in didn't reliably return the current URL and leaving it blank or omitting it failed, I wrote the div tag in Javascript:

<script>
document.write("<div class='fb-comments' data-href='" + window.location.href + "' data-num-posts='2' data-width='400'></div>");
</script>

Of course, this will include the data in the query string but you should be able to exclude that if that's what you want.
