Here's the function you can use in _skin.class.php to extract URL parts

function add_og_url()
{
	global $ReqURL, $ReqHost, $ReqURI;
	if( preg_match('~^https?://(?<blogname>[^.]+)\.[^/]+/(?<prefix>[^/]+)/(?<parent>[^/]+/)?(?<cat>[^/]+/)((?<post>[^?]+))?~i', $ReqURL, $parts) )
	{
		$query = @$_SERVER['QUERY_STRING'];
		$fb_url = 'http://tilqi.com/'.$parts['blogname'].'.php/';
		if( !empty($parts['cat']) )
		{
			$fb_url .= $parts['cat'];
		}
		if( !empty($parts['post']) )
		{
			$fb_url .= $parts['post'];
		}
		if( !empty($query) )
		{
			$fb_url .= '?'.$query;
		}

		add_headline('<meta property="og:url" content="'.format_to_output( $fb_url, 'htmlattr' ).'" />');
	}
}

for anyone reading this, turns out, there is no way to "transfer" your likes when you change your url structure.

Hey, I forgot that we can add redir=no param. Try it with $fb_url

@tilqicom: you can transfer likes, basically by keep using the old og:url: http://facebook.stackoverflow.com/a/10152342/15690

I just did that with a platform where the domain changed.

Well, sam2kb helped adding old meta but because of the redirect it did not work.
He did say above something about a redir param but i have no idea what he meant by that, and what i should do

I mean isnt there a way to let facebook record og:url as index.php?pid and dont get involved with pretty urls ?

Sure, you can put whatever in og:url - however, when moving domains/url's, you want to keep the previous one.

I am not sure if b2evo adds og:url itself in default templates etc..

I just came across this thread and wanted to leave a pointer at the fix for it.

Thanks for the tip, checked that topic but i am not sure what to do

With "redir=no" you can use any valid URL b2evo will not redirect you to canonical URL.

Say, you can use index.php?p=444&redir=no and you won't be redirected to index.php/post-title

So as suggested above, try meta og:url with your old b2evo URLs ending on "redir=no"

well, appending index.php?p=id&redir=no causes invalid request for me:

http://tilqi.com/index.php?p=1425&redir=no

and /permalink&redir=no causes a 404 (which i redirect to home).

This one works, also try index.php with blog=x
http://www.tilqi.com/resimli-sozler.php?p=1425&redir=no

XX is the ID for "resimli-sozler" blog
http://www.tilqi.com/index.php?p=1425&blog=XX&redir=no

Oh, i was missing blog=x there.It throws a warning though:

Open Graph Warnings That Should Be Fixed
Mismatch og:url and canonical url	og:url tag in the header is not the same URL as rel='canonical' link in the html.

Seems like i will lose some more likes, but on the bright side, i will finally be able to fix my og:url for future without any dependency, regardless of permalink, blog name, subdomain etc. etc.
