I got the sample code from Facebook to post a message. At first it worked fine. The next day I tried to clean up the code and it stopped working. I brought back the sample code from Facebook, to take out all my changes, and it still did not work.
I put in print statements to follow the code.
$user_id is false, so it displayes a login in. The login in no longer goes to a login in screen. It calls my return url, which then sees $user_id as being false and diplays the login in again.
I did notice when my call back was being called, I had the following values:
v?state=452c9492a3d51962909f5e000bcb0965
and code
code=AQDucDgsdc3lZFVN2MC3Oj2oB0n1LT4FjOrG3MbgwL4uhh--LS-mRdtjU-6oSUZxsR6UhTKuUDVn3hrasJAe5r1I6ksIDJz1nnTo1mjCqEInJKvQ2qK5A-N3_Nt5buGLqsirb8ccg21N4nWVWkk_iRePwX9f68qK1j-2O6E_USpKvRJeNP3bcwLBiTBJpDVu7aA#=
I was wondering maybe when I was trying to clean up the code and kept running it, Facebook flagged my app as spamming? I posted 26 posts to my wall - is that too many? And how would I check if my app has been flagged as a spammy app?
This is the sample code I used
<?
// 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('facebook.php');
$config = array(
'appId' => 'myappid',
'secret' => 'mysecret',
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
?>
<html>
<head></head>
<body>
<?
if($user_id) {
print ("tryinmg to do a poast");
// We have a user ID, so probably a logged in user.
// If not, we'll get an exception, which we handle below.
try {
$ret_obj = $facebook->api('/me/feed', 'POST',
array(
'link' => 'www.example.com',
'message' => 'Posting with the PHP SDK!'
));
echo '<pre>Post ID: ' . $ret_obj['id'] . '</pre>';
} 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.
print ("face book exception log in");
$login_url = $facebook->getLoginUrl( array(
'scope' => 'publish_stream'
));
echo 'Please login.';
error_log($e->getType());
error_log($e->getMessage());
}
// Give the user a logout link
echo '<br />logout';
} else {
print ("no user login in do login");
// No user, so print a link for the user to login
// To post to a user's wall, we need publish_stream permission
// We'll use the current URL as the redirect_uri, so we don't
// need to specify it here
$login_url = $facebook->getLoginUrl( array( 'scope' => 'publish_stream' ) );
echo 'Please login.';
}
?>
</body>
</html>
Naturally, Facebook has a limit for the number of post per day your app can make to a user wall. And FB have policy for user to report spammy apps as well.
The exact maximum number of posts depends on your application FB ranking. In my experience, 26 posts on a user wall is near the limit for new application.
If that is the case, you should receive the error message from Facebook, which says something like "you have reached limit of posts..."
P/s: It seems you need time to refactoring your question, though. If I have not met this situation before, I won't understand your question.

I have tried to search this, but have found no answers. I have [had] a working application on Facebook up until yesterday, then all hell broke loose and it simply doesn't come up. Please keep in mind, nothing changed on my end. The application has been running for over a year with no problems.
Yesterday, I accessed the application like normal and got an additional permission request for access to my friends list. Strange, again because I have made no changes to the code or the configuration on FB. I accepted the request and now instead of the application coming up, it simply goes into an endless oauth login redirect loop. In fact it doesn't even look like it ever calls my application url as I cannot debug it (it never breaks on the code)
I guess my question is, does anyone know of something changing recently on FB to cause this?
The application can be found at: https://apps.facebook.com/myworkoutlog
And as I wrote this, the app came up, but after closing the browser and starting again, back into the endless loop. Any help would be great. If you need additional information, please just ask.
Edit:
I finally got it into debug and it breaks when I try to get an access_token using a verification code: (OAuthException - #100) Invalid verification code format.
Try this it works for me ;)
include_once "facebook.php";
$facebook = new Facebook(array(
'appId' => 'xxxxxxxxxxxxxxx',
'secret' => 'xxxxxxxxxxxxxxx',
'cookie' => true
));
$fb_user = $facebook->getUser();
if($fb_user){
if(isset($_GET['code']) && isset($fb_user)){
$fbAppNs = 'appOnFacebookNameSpace';

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?
I've been struggeling with the facebook connect for a few days now, I'm only using the PHP SDK downloaded from facebook.
I first used some custom code, but after that failed I just copied the code on facebook, but this still fails.
Is there anything I do wrong? I've created an app on facebook, added the right domain (I get redirected correctly).
Once people login, this is the URL they get redirected to:
http://www.mysite.com/index.php?state=33e35654a84559d246c152ed10e8150b&code=AQBGxCMu4vgbw5HgU8EIoyq8rhuHaKvtJQR-VbPMVH8bd2JMIRcxojqJ-l7XrjIdG9TNN05el14Jv8isbHbUWj9so-CdhaEqj7tLR-Rj6-JaOTA7QErrpfN_0XQN1CGCmvmTL6ZtoUupgkVwkzq_CWDT9lSoDPvNHu2F67Jqlsi2DfQZGE1J7pDzujBoSoJhDhs#_=_
The code I copied from facebook:
<?
// 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('classes/facebook/facebook.php');
$config = array(
'appId' => 'appID here',
'secret' => 'secret here',
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
?>
<html>
<head></head>
<body>
<?
if($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','GET');
echo "Name: " . $user_profile['name'];
} 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.';
}

It turns out it had something to do with the certificate, after some looking around I found out that changing
if (curl_errno($ch) == 60) {
// CURLE_SSL_CACERT
to
if (curl_errno($ch) == 60 || curl_errno($ch) == 77) {
// CURLE_SSL_CACERT
solves the problem
I've read a lot of tutorials/articles/questions here about this, as well as trying to find something useful in the fb documentation.
So far I've made no progress at all myself so any input would be greatly appreciated, I'm simply trying to access a list of my photos but all I get is an empty array.
I know I've added more req_perms than I need probably, I just copied the ones from a "working tutorial" that didnt work for me, and after reading a thread here I also added user_photo_video_tags because that had worked for the thread poster (again, not me).
I've gotten the dialog to allow photos sharing my photos with my app, login works without any problems, the access token I get seem to be correct, after logging in I have visited:
https://graph.facebook.com/me/photos?access_token= and the token, and gotten an empty array, if I wasnt logged in or the access_token wasnt linked to my app there would be some error, but all I get is an empty array.
Thanks in advance for any input.
Thanks to Chaney Blu I was able to validate my permissions:
{
"data": [
{
"installed": 1,
"status_update": 1,
"photo_upload": 1,
"video_upload": 1,
"create_note": 1,
"share_item": 1,
"publish_stream": 1
}
]
}
<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);
require_once 'library/facebook.php';
$app_id = "xxxxxxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
$loginLink = $facebook->getLoginUrl(array(
'scope' => 'user_status,publish_stream,user_photos,user_photo_video_tags'
));
$logOutLink = $facebook->getLogoutUrl();
$user = $facebook->getUser();
if ($user) {
try {
// User logged in, get token
$token = $facebook->getAccessToken();
//var_dump($token); dumped successfully
// Get public profile info
$user_profile = $facebook->api('/me');
//var_dump($user_profile); dumped successfully
$photos = $facebook->api('/me/photos?access_token=' . $token);
var_dump($photos); // Empty array, BAH!
} catch (FacebookApiException $e) {
$user = null;
}
}
?>

Not sure if this is the problem, but try this. It appears you're using the latest PHP SDK. In your getLoginUrl(); calls, try changing 'req_perms' to 'scope'.
Like this:
$loginLink = $facebook->getLoginUrl(array(
'scope' => 'user_status,publish_stream,user_photos,user_photo_video_tags'
));
You can verify that you've authorized the correct permissions by visiting https://graph.facebook.com/me/permissions/?access_token=XXXX
After testing some other permissions I noticed facebook weren't updating the permissions to my token, even when logging out of the app, logging in again and accepting new permissions nothing changed when I looked at the Graph permissions link I got from Chaney Blu.
I used that link to verify the token from facebooks graph api page http://developers.facebook.com/docs/reference/api/ and noticed that token had access to user_photos but not my token.
Going into my facebook settings and removing the app made facebook update my permissions the next time I signed into the app.
Thanks to Chaney Blu for putting me on the right track. Would vote you up if I had the reputation.
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.
