No result displayed in retrieving User data in facebook iFrame application using users_getInfo() -

I am writing a PHP iframe / facebook connect application with a PHP client library and in one of the pages, retrieve me The user's current location, either the city or the country

$ user_id = $ facebook- & gt; Need_login ($ required_emptive = 'user_location, publish_stream, email, read_stream, user_about_me, user_activities, user_birthday, user_hometown, user_interests, user_likes, user_status);

This is the code I am using in my application,

  $ userInfo = $ facebook-> API_climate-> User_getienfo ($ user_id, array ('current location')); Var_dump ($ userInfo); $ Location = ($ userInfo [0])? $ UserInfo [0] ['current_location']: $ user INFO ['current_location']; Echo "UserInfo:". $ Location;  

The result of var_dump ($ userInfo) is string (0) "" and the echo of $ space is empty.

Please help someone please help me.

That's because you generated an error while copying the example. You have wrong method signing.

  // Your Version $ facebook-> API_climate-> User_getInfo ($ user_id, 'last_name', 'first_name'); // example $ facebook-> API_climate-> User_getienfo ($ uid, 'last_name, first_name');  

See the difference? This is only two criteria - the second area has a comma-separated list of names.

Therefore, since you are not requesting the field correctly from the API, this response is not available.

So the error is when trying to read it.
