无法在FaceBook上获取我朋友列表的在线状态

Question

这是我的fql:

$fql = "SELECT uid, name, online_presence, status 
         FROM user 
        WHERE uid IN ( SELECT uid2 FROM friend WHERE uid1 = '".$user_id."') ";

该online_presence值总是返回null.

Answer 1

您的查询有错误...

只需更换

WHERE uid IN

到

WHERE 2 IN

询问

$fql = "SELECT uid, name, online_presence, status 
         FROM user 
        WHERE 2 IN ( SELECT uid2 FROM friend WHERE uid1 = '".$user_id."') ";
