Question

I’m trying to create a facebook login url using Facebook PHP SDK (v.3.2.0) from
https://github.com/facebook/facebook-php-sdk
below is my code

$config = array(    'appId'  => '***',  
                    'secret' => '***',  
                    'cookie' => true 
                    );
require_once("facebook.php");

$facebook = new Facebook($config);

$params = array('scope' => 'user_birthday, user_location, email',
                'redirect_uri' => "http://my_domain.in/user/fb",    
                'display' => 'popup'
                );
$loginUrl = $facebook->getLoginUrl($params);

the problem is when the loginUrl is clicked it will give error from facebook as below:

API Error Code: 100 API Error Description: Invalid parameter Error
Message: Display type popup. isn’t valid on http://www.facebook.com. You
should access a different domain (m.facebook.com, http://www.facebook.com),
or use one of the following supported display types: page, popup,
iframe, touch, none

the question is where did i go wrong?
fyi, the very same code were fine before, somehow it’s not working now, i kinda missed when the problem actually happen at first, but in between i did upgrade the facebook-php-sdk from 3.1.1 to 3.2.0, n possibly the domain and url settings in my facebook app.

app domain : my_domain.in
site url : http://www.my_domain.in

furthermore,
even my i changed the params into

$params = array('scope' => 'user_birthday, user_location, email',
                'redirect_uri' => "http://my_domain.in/user/fb"
                );

i still receive an error with different message

API Error Code: 100
API Error Description: Invalid parameter
Error Message: Unsupported scope: ‘email.’. Supported scopes: ads_management create_event create_note email export_stream friends_about_me friends_activities friends_birthday friends_checkins friends_education_history friends_events friends_games_activity friends_groups friends_hometown friends_interests friends_likes friends_location friends_notes friends_online_presence friends_photo_video_tags friends_photos friends_questions friends_relationship_details friends_relationships friends_religion_politics friends_status friends_subscriptions friends_videos friends_website friends_work_history manage_friendlists manage_notifications manage_pages offline_access photo_upload publish_actions publish_checkins publish_stream read_friendlists read_insights read_mailbox read_page_mailboxes read_requests read_stream rsvp_event share_item sms status_update user_about_me user_activities user_birthday user_checkins user_education_history user_events user_games_activity user_groups user_hometown user_interests user_likes user_location user_notes user_online_presence user_photo_video_tags user_photos user_questions user_relationship_details user_relationships user_religion_politics user_status user_subscriptions user_videos user_website user_work_history video_upload xmpp_login

please help,
thanks.

Answer 1

SOLVED.

the problem was there was an additional character (a dot) in my href attribute,
as coded below

<a href="<?php echo $loginUrl; ?>.">

noticed it after reviewing again the error message (popup*.* email*.*).

it simply worked when i removed the character.
so it is not caused by the facebook-php-sdk version nor the domain/url settings in my facebook app.

sorry for any trouble caused.
