Answer by Jonathan_Ng for Graph API new feed post object-Attachment not showing

I think the 'object_attachment'=>$photo_id won't work any more.You should change it to 'picture'=>$photo_url

$photo_Url = "link to your photo";//Valid Facebook Photo ID...        $facebook = new Facebook($config);$attachment =  array('access_token' => $user_token,'message' => "Test Message",'caption' => "THis is a Caption",'name' => "Test Name",'description' => "This is a description",'link' => 'http://url.com/','picture' => $photo_Url,);$response = $facebook->api("/".$userID."/feed/", 'POST', $attachment);
