Help With Tagging Photo Via Facebook Sdk Php 2.0

[codenam25]

Hi,

I run a community page in facebook for my website. I made an facebook app an post all my updates of the website to my facebook page via the app. Now i want to tag some people (may be not my friends or my page members) in the post (photo) published in my page via my app. I tried and im sucessfull in tagging myself to the photo post by this:

 

"message" => $title,

'source' => '@'.$pic, // ATTENTION give the PATH not URL

'tags' => array(array(

'tag_uid' => '1000xxxxxxxxx',

'x' => '1',

'y' => '0',

)),

 

But the problem is when i add the id of other users (may be not my friends or my page members) the photo post bears nothing, no tags at all, it only tags me. I serached google many times couldn't find the solution. Please help me wiith this.
