如何使用FB graph API标记朋友？

Question

I am trying to tag a friend in FB message to be posted, I am using PHP, and for FB I am using FB Auth API 2.0, I have tried to get related information from facebook developers forum, however can't find enough information for this one. Can anyone suggest me from where to get started for this? any links to related documentation or forum links using which I can get started?

Answer 1

You use the message_tags field of the Post object. Check out the docs :

message_tags: object containing fields whose names are the indexes to where objects are mentioned in the message field; each field in turn is an array containing an object with id, name, offset, and length fields, where length is the length, within the message field, of the object mentioned

Answer 2

Something like this:

    $facebook->setFileUploadSupport(true);
    $tags = array(
    ‘tag_text’ => ‘ak Yip’,
    ‘tag_uid’ => 642536423,//it’s my id on facebook as a sample
    ‘x’ => 10,
    ‘y’ => 10,
    );

    $args['tags'] = array($tags);
    $args['image'] = ‘@’ . realpath($fn);
    $data = $facebook->api(‘/me/photos’, ‘post’, $args);

Note: **One:Your app need to get permissions like 'user_photo_video_tags' and 'friends_photo_video_tags'.

Two:X,Y is proportion, not coordinate. Don't put value over 100.**
