Facebook method photos_addTag not working

Question

How to add tag to facebook photo using php?

I have this code, where $pidis the photo id, $userIdis my facebook id.

Of course I have been using this before>

$facebook = new Facebook($appapikey, $appsecret);
$user_id = $facebook->require_login();
$test = $facebook->api_client->photos_addTag ($pid,$user_id, "text", 50.0, 50.0, '', $user_id);

$test returns 1

but photo not tagged

Can someone write me what I'm doing wrong?

Answer 1

  //  tag photo parameter
  $pid = $uid.'_'.$pid; // pid is the photo id, after it uploaded, you need to add the owner id(uid) in front of it, and the real pid is inside the 'link' of the photo returned json.
  //tag_uid = $uid;
  //x = percentage of x position
  //y = percentage of y position
  $access_token = $session['access_token'];

  $tag0 = array('tag_uid'=>$fd0,'x'=>'30.0','y'=>'85.0');
  $tag1 = array('tag_uid'=>$fd1,'x'=>'35.0','y'=>'85.0');
  $tag2 = array('tag_uid'=>$fd2,'x'=>'40.0','y'=>'85.0');
  $tag3 = array('tag_uid'=>$fd3,'x'=>'45.0','y'=>'85.0');
  $tag4 = array('tag_uid'=>$fd4,'x'=>'55.0','y'=>'85.0');
  $tag5 = array('tag_uid'=>$fd5,'x'=>'60.0','y'=>'85.0');
  $tag6 = array('tag_uid'=>$fd6,'x'=>'65.0','y'=>'85.0');
  $tag7 = array('tag_uid'=>$fd7,'x'=>'70.0','y'=>'85.0');

  $tags = array($tag0,$tag1,$tag2,$tag3,$tag4,$tag5,$tag6,$tag7);
  $facebook->api(array('method'=>'photos.addTag','pid'=>$pid,'tags'=>json_encode($tags)));

However, in the new facebook policy, they do not seem to prefer applications to automatically tag people in photos.
