I got a problem regrading with my apps which is once I go to my apps, it sure will show me a login page instead of allow page?
it always display the login page 1st then only display allow page, I had tried other apps, if I am 1st time user, It sure will appear the allow page only, it did not show me the login page.
my question is how to I avoid my login page direct go to allow page?
here is my login page picture
here is my apps link
https://apps.facebook.com/christmas_testing/
here is my facebook php jdk api coding
<?php
$fbconfig['appid' ] = "XXXXXXXXXXXXX";
$fbconfig['secret'] = "XXXXXXXXXXXXX";
$fbconfig['baseUrl'] = "myserverlink";
$fbconfig['appBaseUrl'] = "http://apps.facebook.com/christmas_testing/";
if (isset($_GET['code'])){
header("Location: " . $fbconfig['appBaseUrl']);
exit;
}
if (isset($_GET['request_ids'])){
//user comes from invitation
//track them if you need
header("Location: " . $fbconfig['appBaseUrl']);
}
$user = null; //facebook user uid
try{
include_once "facebook.php";
}
catch(Exception $o){
echo '<pre>';
print_r($o);
echo '</pre>';
}
// Create our Application instance.
$facebook = new Facebook(array(
'appId' => $fbconfig['appid'],
'secret' => $fbconfig['secret'],
'cookie' => true,
));
//Facebook Authentication part
$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown'
)
);
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
//you should use error_log($e); instead of printing the info on browser
d($e); // d is a debug function defined at the end of this file
$user = null;
}
}
if (!$user) {
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
exit;
}
//get user basic description
$userInfo = $facebook->api("/$user");
function d($d){
echo '<pre>';
print_r($d);
echo '</pre>';
}
?>
This is an effect of the new auth dialog features facebook recently rolled out.
There are two "allow/login" screens when using this new dialog :
Regular permissions such as - user_about_me, user_birthday, user_photos.
Extended permissions such as - read_insights, offline_access, publish_actions.
Each will display its own dialog. First the regular permissions will appear and after that the extended permissions will appear (if you have requested extended permissions)... This happens when the user first logs in, and possibly later if you want decide to add additional permissions to your app.
Taken from the Open Graph Beta › Auth Dialog
The updated Auth Dialog will display a set of user and friends permissions on the first dialog, and other extended permissions (if any) on a second dialog screen.
You can disable this feature and go back to the older auth dialog by changing the setting inside your app. Goto the advanced tab in the settings of your app and uncheck the Enhanced Auth Dialog check-box.
On the scope parameter, add 'offline_access' permission. With this,the user grant permission to the application even if the user is offline. The access_token that you will get is non-expiry.

I develop a Facebook application and I use PHP-sdk I use the algorithm described in the official documentation to allow user joining my app then I store his/her user_id in the database. My app uses publish_stream permissions so it publishes posts to the user's time line automatically.
I found that the application, always, does not able to publish posts for some of the registered users in the database (not all of them). I account this for they may be registered to the database before they give approval for the required permissions. The following is a blue print for the code that I use from the official documentation of Facebook api:
<?php
require_once('php-sdk/facebook.php');
$config = array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
?>
<html>
<head></head>
<body>
<?php
if($user_id) {
try {
/* $user_profile = $facebook->api('/me','GET');
echo "Name: " . $user_profile['name'];*/
//Here I run the code to save.
saveTheUserIdToRecordInTheDB($user_id);
//hypothetical function to save
} catch(FacebookApiException $e) {
// If the user is logged out, you can have a
// user ID even though the access token is invalid.
// In this case, we'll get an exception, so we'll
// just ask the user to login again here.
$login_url = $facebook->getLoginUrl();
echo 'Please login.';
error_log($e->getType());
error_log($e->getMessage());
}
} else {
// No user, print a link for the user to login
$login_url = $facebook->getLoginUrl();
echo 'Please login.';
}
?>
</body>
</html>
My, main, question is: If the user clicked on the login link, and then he/she does not continue for any reason (losing the internet connection, refusing giving the permissions to the app, etc), would it possible the hypothetical function saveTheUserIdToRecordInTheDB() to run and save that user's Facebook's ID to the database?
Or What's the explanation for there are some users are not posts publishable?
Do you have an example of how to confirm that the person trying to access the content of your app is a member of a specific facebook group, using php? I've read through the developer docs and all it managed to do was confuse me even more. I've seen posts similar to this one but they only show me how to print a list of members...
I need to know how to get the list and see if the user trying to access the app is a member of the group so that I can either a: allow access or b: deny access and re-direct the user to the group page so they can request membership...
Yes its pretty simple, you just need to know the ID of the group you want to do that and ask for the scope user_groups permission, so you can query the groups the user have.
With the PHP SDK you can do this:
<?php
// Remember to copy files from the SDK's src/ directory to a
// directory in your application on the server, such as php-sdk/
require_once('php-sdk/facebook.php');
$config = array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
if($user_id) {
// We have a user ID, so probably a logged in user.
// If not, we'll get an exception, which we handle below.
try {
$user_profile = $facebook->api('/me?fields=id,name,groups','GET');
$user_belongs_to_group= FALSE;
foreach($user_profile['groups']['data'] as $group){
if($group['id']==YOUR_GROUP_ID)
$user_belongs_to_group=TRUE;
}
if($user_belongs_to_group){
//Alright! the user belongs to the group
}
else{
//Oh snap you don't belong here, but you can if want to
}
} catch(FacebookApiException $e) {
// If the user is logged out, you can have a
// user ID even though the access token is invalid.
// In this case, we'll get an exception, so we'll
// just ask the user to login again here.
$login_url = $facebook->getLoginUrl();
echo 'Please login.';
error_log($e->getType());
error_log($e->getMessage());
}
} else {
// No user, print a link for the user to login
$login_url = $facebook->getLoginUrl();
echo 'Please login.';
}
?>
Some of this code I grabbed from the facebook, you can see the data that is returned when query for groups here: https://developers.facebook.com/tools/explorer
Press the plus sign after the name go to connections, choose groups and press send
You are in a catch-22, you will need the user to grant permission to his groups via the user_groups permission.
I'm working on a site that uses the Facebook PHP SDK. It is working great, and after 2 hours, whenever I try to get onto one of the general pages on the site, I get...
Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user.
If I go back to the index page, I get a new access token and everything works properly again...for 2 hours.
What code can I put on my webpages to redirect to the index page when the access token has expired?
Thanks for helping this noob.
You must redirect user to page that has authorized code.
If your user not deauthorized app , the Oauth dialog isn't appear.
For more information go to
Access Token & Handling
You can put a try / catch block in your code.
Put each Facebook API call in such block and if an exception occurs you can redirect the user to the right resource by header('Location: <url>');:
try {
# FB API call
}
catch(OAuthException e) {
header('Location: <url>');
}
Have a file that goes like this and include it in your webpages.
$facebook = new Facebook(array(
'appId' => "app id",
'secret' => "app secret",
));
$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl();
if ($user) {
try {
$me = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
}
}
else {
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
}
I am trying to integrate my Codeigniter website with the Facebook PHP SDK. What I want to do is let a user share an article from my site on their facebook wall, if they are logged into a facebook account. My library appears to load correctly, but everytime I try to do something, I get some kind of error... primarily with the auth. getUser does not appear to return the correct results. I set up my facebook application and set the config vars for my library, but no luck. It says I am not logged into facebook. When I click on the "login" anchor, the link takes me to the same page, but with the facebook url, and doesn't ask me to login with the app. Here's my code:
function facebook($article_id){
$config = array(
'appId' => '276870792431073',
'secret' => '8d49eee575413fb9a8063d22f65dbf6a'
);
$this->load->library('facebook', $config);
$user = $this->facebook->getUser();
if($user){
try {
$user_profile = $this->facebook->api('/me');
} catch (FacebookApiException $e){
error_log($e);
$user = null;
}
}
if($user){
$article = $this->article->fetch_article($article_id);
$config = array(
'message' => 'I just read an '.anchor('articles/'.url_title($article['title']).'/'.$article_id, 'article').' on '.anchor('', 'TrackTheOutbreak.com').'!',
);
$this->facebook->api('/me/feed', 'post', $config);
} else {
$data['MESSAGE_TITLE'] = 'Authentication Error';
$data['MESSAGE_TEXT'] = 'You must be logged into an existing Facebook account to use this feature. Click '.anchor($this->facebook->getLoginUrl(), 'here').' to login.';
$this->parser->parse('error_body.tpl', $data);
}
}
In order to access a users information and post anything to their wall you first need to get a access token from them. To do that you need to make sure that you have gained their permission through Facebook's FB_login (and then Open Graph). I would double check with this guide and make sure that you have everything set up properly to post to their timeline.

I hope this helps
I have a website and a facebook page for the website. For most of the news update, I post them on the facebook page's wall.
Now I want to show the wall's content of that facebook page on my website, just like the facebook's Like Box with "stream" enabled: http://developers.facebook.com/docs/reference/plugins/like-box/
However, I only want to show the stream, and perfectly can show it in my own presentation. So is it possible to get only the content of a facebook page by facebook's API?
I think if you use the SDK you can get it by using
fb->api("/{id}/feed");
There's a php and a javascript sdk.
But you also need an access token now to get the feed of a page.
EDIT: Here's a copy of example.php (from the php-sdk) modified for your purpose.
include_once("facebook-sdk/facebook.php");
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'APP_ID GOES HERE',
'secret' => 'SECRET GOES HERE',
));
// Get User ID
$user = $facebook->getUser();
// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
// This is where we grab the posts
$wall_posts = $facebook->api('/courseyou/posts');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
?>
<?php if ($user): ?>
Logout
<?php else: ?>
<div>Login with Facebook</div>
<?php endif ?>
<h3>Wall Posts</h3>
<?php
foreach ($wall_posts["data"] as $post) {
echo "<p>".$post["from"]["name"].": ".$post["message"]."</p>";
}
?>
As far as I know you need an access token to view a page's posts/feed with the api, which makes me think that you need the user to login with facebook.... I'm fairly new to this, but you should look into how to get an access token, because you need one for this.
