Facebook Like and Comments in Symfony2
Nov 15th, 2011Getting the full current URL without the GET parameters might be tricky.
The problem
If you followed the instruction to get the Facebook like button or the Facebook comments plugin working on your website, you must have something like:
<div class="fb-like" data-href="http://my-website.com/my-page"></div>
For Facebook comments, you will have fb-comments
instead of fb-like
, but it’s the same problem. You generate dynamically such piece of HTML with Twig in order to have:
<div class="fb-like" data-href="{{ app.request.uri }}">
But you may want to avoid GET parameters (for instance Google analytics parameters) like these ones:
http://my-website.com/my-page?utm_source=email&utm_campaign=blahblah
As comments and likes counts are for one unique URL, you will end up scattering your like count and comments accross all the URLs displaying the same page.
The fix
Here is the trick to get the current URL without the GET parameters, enjoy!
<div class="fb-comments" data-href="{{ app.request.getUriForPath(app.request.pathInfo) }}">
