Query strip is removed from open graph url

Question

In relation to this question: Dynamic generation of Facebook Open Graph meta tags

I have followed these instructions but the api seems to remove my query string so that the url passed into the aggregation contains none of my dynamic information. If I enter the url with the query string into the debugger it doesn't remove it and works fine. I can confirm my og:url meta tag does also contain the same query string not just the base url. What am I doing wrong?

I was having a similar issue and solved it like this:

So assuming you're doing your post request like it shows in the tutorial, youre Javascript probably looks something like this:

  function postNewAction()
  {
      passString = '&object=http://yoursite.com/appnamespace/object.php';

      FB.api('/me/APP_NAMESPACE:ACTION' + passString,'post',
         function(response) {
              if (!response || response.error) {
                  alert(response.error.message);
              } 
              else {
                  alert('Post was successful! Action ID: ' + response.id);
              } 
          }
      );    
  }

And since you say you want to generate meta tags dynamically, you're probably adding a parameter to the url (passString) there like so:

  passString = '&object=http://yoursite.com/appnamespace/object.php?user=' + someuser;

This is wrong.

What you need to do is to make the url a 'pretty url' and use htaccess to decipher it. So:

  passString = '&object=http://yoursite.com/appnamespace/object/someuser';

Then your htaccess file will tell your site that that url actually equates to

  http://yoursite.com/appnamespace/object/object.php?user=someuser

Then you can use GET to store the user parameter with php and insert it however you like into your meta tags.

In case youre wondering, in the og:url meta tag's content will be:

  $url = 'http://yoursite.com/appnamespace/object/object.php?user=' . $_GET[$user];

Does that help?
