I am using php SDK example from github:
$user_id = $facebook->getUser();
As far as I understand this should open the facebook login dialog with the permissions I defined for the app, but I only see the basic permissions.
The option to check authenticated referrals is no longer available on the facebook app settings form.
Do I have to somehow request the permissions in the code itself?
You need code, to make permission window to pop out.
Something like this shold help:
Do you check on user?
// Init the Facebook SDK
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
// Get the current user
$user = $facebook->getUser();
if (!$user) {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => $scope,
'redirect_uri' => $app_url,
));
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
}
else{
$user_profile = $facebook->api('/me');
// STUFF
}

I'm doing a facebook app and it works fine on my server and url, when i try to integrate it as a "App on Facebook" it fails to load or login after logout. I believe that the scope for permissions is giving some problems.
The url for the server: http://veritas.betamass.com
The url for the "App on Facebook" side: https://apps.facebook.com/orientacionveritas/
Note that if you login successfully on the server the you will be able to see the "App on Favcebook, if not you will get a nothing.
The code that makes the connection to facebook:
if(!isset($_SESSION['user']))
{
//Application Configurations
$app_id = "148133482012457";
$app_secret = "24d0088e17c1dcb33ac6bb424a5d2a5c";
$site_url = "http://veritas.betamass.com/";
try{
include_once "src/facebook.php";
}catch(Exception $e){
error_log($e);
}
// Create our application instance
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true,
));
// Get User ID
$user = $facebook->getUser();
$access_token = $facebook->getAccessToken();
$facebook->setAccessToken($access_token);
// We may or may not have this data based
// on whether the user is logged in.
// If we have a $user id here, it means we know
// the user is logged into
// Facebook, but we don�t know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.
//print_r($user);
if($user){
// Get logout URL
$logoutUrl = $facebook->getLogoutUrl();
}else{
// Get login URL
$params = array(
'scope' => 'read_stream, publish_stream, email, user_about_me, user_hometown, user_education_history, user_interests',
'redirect_uri' => $site_url,
);
$loginUrl = $facebook->getLoginUrl($params);
/*$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'read_stream, publish_stream, email, user_about_me, user_hometown, user_education_history',
'redirect_uri' => $site_url,
));*/
}
If the user doesn't exist or doesn't have a session, you need to make them login first. Your code doesn't take this into account.
Try redirecting the user to $facebook->getLoginUrl() if the session / $facebook->getUser() returns false.
I am currently developing a facebook application using the php sdk and the js sdk. (I need both of them)
When a user has not yet authorized the application and loads the canvas page (https://apps.facebook.com/app_name/), nothing happens, he just gets a blank page with the facebook bar on top.
But if he loads the direct url of the application (https://my_app.mydomain.com), it works fine and he is redirected to the OAuth Dialog. If he authorizes the application, he is then redirected to https://apps.facebook.com/app_name/ and the iframe loads correctly.
If the user has already authorized the applications, both links are working (https://apps.facebook.com/app_name/ and https://my_app.mydomain.com).
Here is my authentication code :
<?php
require 'php-sdk/facebook.php';
$facebook = new Facebook(array(
'appId' => '327991330620101',
'secret' => '79asecretcc4300',
'cookie' => true
));
$user = $facebook->getUser();
if ($user) {
try {
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
$user = null;
}
}
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$params = array(
'scope' => 'publish_stream',
'redirect_uri' => 'https://apps.facebook.com/quiet_quies/'
);
$loginUrl = $facebook->getLoginUrl($params);
header('Location: ' . $loginUrl);
}
Does anybody have an idea about this ? It's really driving me mad...
Thanks for you help.
yes, #CBroe is right, in your php code try replacing header('Location: ' . $loginUrl); line with
echo "<script language=javascript>top.location.href ='".$loginUrl."'</script>";
it should work then.
after get my posts in my web page , then if user login he can add like / comment to that post problem is am getting an error if any user try add like or comment
200 Permissions error
if i login in with my username and password i can make like or add comment !!
am sending like via :
jQuery.post('https://graph.facebook.com/'+comm_id+'/likes/',{
access_token : "<?php echo $access_token ?>"
});
CODE :
$facebook = new Facebook(array(
'appId' => '',
'secret' => '',
'cookie' => true,
));
$user = $facebook->getUser();
if ($user) {
if (session_id()) {
} else {
session_start();
}
$access_token = $facebook->getAccessToken();
//check permissions list
$permissions_list = $facebook->api(
'/me/permissions', 'GET', array(
'access_token' => $access_token
)
);
//check if the permissions we need have been allowed by the user
//if not then redirect them again to facebook's permissions page
$permissions_needed = array('publish_stream', 'read_stream', 'manage_pages');
foreach ($permissions_needed as $perm) {
if (!isset($permissions_list['data'][0][$perm]) || $permissions_list['data'][0][$perm] != 1) {
$login_url_params = array(
'scope' => 'publish_stream,read_stream,manage_pages',
'fbconnect' => 1,
'display' => "page",
'redirect_uri' => 'http://localhost/fb/index.php',
);
$login_url = $facebook->getLoginUrl($login_url_params);
header("Location: {$login_url}");
exit();
}
}
}else {
//if not, let's redirect to the ALLOW page so we can get access
//Create a login URL using the Facebook library's getLoginUrl() method
$login_url_params = array(
'scope' => 'publish_stream,read_stream,manage_pages',
'fbconnect' => 1,
'display' => "page",
'redirect_uri'=>'http://localhost/fb/index.php',
);
$login_url = $facebook->getLoginUrl($login_url_params);
//redirect to the login URL on facebook
header("Location: {$login_url}");
exit();
}
$logoutUrl = $facebook->getLogoutUrl();
which access token is for the user is loged in
Make sure you have the publish_stream permission for any user you want to be able to create posts for. Remember, creating a comment is still creating content.
Checkout the publish_stream permission on Facebook's permissions documentation
Enables your app to post content, comments, and likes to a user's
stream and to the streams of the user's friends. This is a superset
publishing permission which also includes publish_actions. However,
please note that Facebook recommends a user-initiated sharing model.
Please read the Platform Policies to ensure you understand how to
properly use this permission. Note, you do not need to request the
publish_stream permission in order to use the Feed Dialog, the
Requests Dialog or the Send Dialog.
I try to post on my wall using facebook api, and offline access tokens.
And every time I has one mistake:
Uncaught OAuthException: (#200) The user hasn't authorized the
application to perform this action
Here is my code:
require 'api/facebook.php';
$facebook = new Facebook(array(
'appId' => "app_id",
'secret' => "app_sec",
"cookie" => true,
'fileUpload' => true
));
$facebook->setFileUploadSupport(true);
$access_token = $facebook->getAccessToken();
$user_id = $facebook->getUser();
$result = mysql_query("UPDATE users SET user_id_facebook='".$user_id."' WHERE id='".$myrow2['id']."'",$db);
$result = mysql_query("UPDATE users SET access_token_facebook='".$access_token."' WHERE id='".$myrow2['id']."'",$db);
if($user_id == 0 || $user_id == "")
{
$login_url = $facebook->getLoginUrl(array(
'redirect_uri' => "http://apps.facebook.com/rapid-apps/",
'scope' => "email,publish_stream,user_hometown,user_location,user_photos,friends_photos,
user_photo_video_tags,friends_photo_video_tags,user_videos,video_upload,friends_videos,offline_access"));
echo "<script type='text/javascript'>top.location.href = '$login_url';</script>";
exit();
}
$post = array(
'access_token' => $access_token,
'message' => 'This message is posted with access token - '
);
$res = $facebook->api('/me/feed', 'POST', $post);
as of may 2nd the offline_access permission will be deprecated and should not be used anymore
in the meantime you have an option to disable this deprecation through the developers site for your application ( https://developers.facebook.com/apps/330955886953999 )...
for further information about the removal see:
http://developers.facebook.com/roadmap/offline-access-removal/
You need to adjust the permissions in your initial app authorization request sent to the user. By default you only gain read-only access to their basic information.
See http://developers.facebook.com/docs/authentication/permissions/
As per usual, FB has me pulling out my hair.
I've been able to test my app in IE9, but when using Firefox, after a user authorizes the canvas app it goes into a redirect loop, adding state and code variables to the URL.
I'm using the javascript and php sdk with this code:
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $application_secret,
'cookie' => true, // enable optional cookie support
));
$user = $facebook->getUser();
if(!($user))
{
echo"<script> top.location.href='" . $facebook->getLoginUrl(array('redirect_uri'
=> $fbconfig['appBaseUrl'],
'scope' => 'manage_notifications,publish_stream,publish_actions'
)) . "'</script>";
exit();
}
I read about adding this:
if (window.location.hash =='#=') window.location.hash=''; but it didn't seem to do anything.
I had the same issue on my latest app.
Solved it by using the code above in the < head > section.
Don't forget to upgrade your PHP SDK to the latest version.
<?
$facebook = new Facebook(array(
'appId' => 'XXX',
'secret' => 'YYY',
));
$user = $facebook->getUser();
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'user_likes'
));
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
exit;
}
?>
