Posting to a friends wall on facebook privately using graph api

Question

I wanted to post a feed to a friends wall from my app and set it as private, which is viewable to the logged in user and the friend. I want to do this using the new Graph api, I saw that if I set the "to" parameter in the feed post, it will be posted to the users friend wall.

I found a code here: http://forum.developers.facebook.net/viewtopic.php?id=56458 (Posted by VovaOnline) (link is dead, as facebook has taken down the forum)

$result = $facebook->api('/me/feed', 'POST', array(
            'from' => array(
                'name' => 'Vladimir Ageenko',
                'id'   => '100001308281502'
            ),
            'name'    => 'TEST NAME',
            'caption' => 'Test Caption',
            'description' => 'Test Description',
            'message' => 'This is test.',
            'privacy' => array(
                'description' => 'Vladimir Sergeevich',
                'value'   => 'CUSTOM',
                'friends' => 'SOME_FRIENDS',
                'allow'   => '100001338940933'
            )
         ));

I am setting the post type as "link". Can anyone tell me what is wrong in this code. One thing I know that "from" field has to be "to" and it has to be passed in a "data" variable. I am not sure how to do it. Can any one help me?

You must encode privacy array, try this:

$privacy = array(
            'description' => 'Vladimir Sergeevich',
            'value'   => 'CUSTOM',
            'friends' => 'SOME_FRIENDS',
            'allow'   => '100001338940933'
        );

$result = $facebook->api('/me/feed', 'POST', array(
        'from' => array(
            'name' => 'Vladimir Ageenko',
            'id'   => '100001308281502'
        ),
        'name'    => 'TEST NAME',
        'caption' => 'Test Caption',
        'description' => 'Test Description',
        'message' => 'This is test.',
        'privacy' => json_encode($privacy)
     ));
