I am trying to create simple php login for using facebook php-sdk. I am using example php code from facebook developers site:
<?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', 'allowSignedRequest' => false // optional but should be set to false for non-canvas apps);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
?>
<html>
<head></head>
<body>
<?php
if($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 {
$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>';
// Give the user a logout link
echo '<br />logout';
} 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 = $facebook->getLoginUrl( array(
'scope' => 'publish_stream'
));
echo 'Please login.';
error_log($e->getType());
error_log($e->getMessage());
}
} else {
// 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>
I have also tried several samples from internet and i always end up with same problem. After i grant permissions from Facebook, Facebook should return page to my page but instead it throws an error (this is translated error from my native language so it might be little bit different from actual English version): "ERROR This function is not available just now: Error processing this request. Try again later." And in URL there is "error_code=2&error_message=" if this helps anything? I have configured my app_id and app-secret in Facebook application page where also display name, email address, domain and site URL is set.
Also in that code i have set correct directory for SDK and app_id and secret_id.
Makes me wonder if i have faulty profile in Facebook apps? Every code i try gives same error. I have tried it with few different people. In users Facebook, applications section appears my application name and given permissions. Most likely this is some simple problem i just don't see, again...
And problem was that my application was not public. Why it takes several hours to find problem and when asked in here you immedialy invent solution by our self? :D

I have a very simple PHP app that retrieves a users & friends RSVPd events using FQL. It is using the latest PHP SKD. The code works perfectly when I am logged in and authenticated as the account that created the app, but it fails with 'unknown error' if I am logged in and authenticated as anyone else.
Here is the login portion of my code
$config = array();
$config['appId'] = $validId;
$config['secret'] = $validSecret;
$facebook = new Facebook($config);
$uid = $facebook->getUser();
// get the url where to redirect the user
$location = "". $facebook->getLoginUrl(array('scope' => 'user_events, friends_events'));
// check if we have valid user
if ($uid) {
try {
$fb_user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
$fb_user_id = NULL;
// seems we don't have enough permissions
print '<script language="javascript" type="text/javascript"> top.location.href="'. $location .'"; </script>';
// kill the code so nothing else will happen before user gives us permissions
die();
}
} else {
// seems our user hasn't logged in
print '<script language="javascript" type="text/javascript"> top.location.href="'. $location .'"; </script>';
// kill the code so nothing else will happen before user gives us permissions
die();
}
print "Authenticated ". $fb_user_profile['name']." <a href='logout.php'>Logout</a><br>";
Here is the FQL portion of my code
$param = array(
'method' => 'fql.query',
'query' => $validFqlQuery,
'callback' => '',
'access_token' => $facebook->getAccessToken()
);
echo "<br>Working...";
$fqlResult = $facebook->api($param);
print_r($fqlResult);
Your App needs to be reviewed by Facebook before it goes Live for
other users to Login.
You do not need to go through Login Review if your app requests these three basic permissions:
public_profile
user_friends
email
To ask your app's users for any other permissions, you will need to submit for review.
However, in order to help you craft your Facebook Login experience, your app's developers will be able to see, and grant, any permission without requiring review by Facebook.
Note: People who are listed in your app's Roles tab will have access
to extended permissions without going through review (e.g.
publish_actions or manage_pages). For example, if you use the Facebook
Plugin for Wordpress to publish your blog posts to your Facebook Page
or Profile, you do not need to submit for review so long as all your
publishers are listed in your app's Roles tab.
Documentation says:
"redirect_uri - (optional) The URL to redirect the user to once the login/authorization process is complete. The user will be redirected to the URL on both login success and failure, so you must check the error parameters in the URL as described in the authentication documentation. If this property is not specified, the user will be redirected to the current URL (i.e. the URL of the page where this method was called, typically the current URL in the user's browser)."
So there is a method to catch if user refused autnentication/permissions, but link to corresponding documentation doesnt exist anymore (https://developers.facebook.com/docs/authentication/).
For the simplicity, redirect_uri is same address as a starting php file, and the php code is as simple as:
require 'facebook.php';
$facebook = new Facebook(array(
'appId' => 'X',
'secret' => 'Y',
));
$user = $facebook->getUser();
if ($user) {
try {
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if (!$user) {
$params = array(
'scope' => 'read_stream, friends_likes',
'redirect_uri' => 'http://myapp.com/app'
);
$loginUrl = $facebook->getLoginUrl($params);
}
Anybody knows how to catch that information?
You can do following to check the permissions:
$permissions = $facebook->api("/me/permissions");
if( array_key_exists('publish_stream', $permissions['data'][0]) ) {
// Permission is granted!
// Do the related task
$post_id = $facebook->api('/me/feed', 'post', array('message'=>'Hello World!'));
} else {
// We don't have the permission
// Alert the user or ask for the permission!
header( "Location: " . $facebook->getLoginUrl(array("scope" => "publish_stream")) );
}
It should be noted that in the newest PHP facebook SDK, there is no method ->api. There also seems to be an issue using this check (sometimes) to get permissions. When using the older SDK, sometimes (randomly by user it seemed) some users were getting "OAuthException: (#412) User has not installed the application" even though a check on the FB access token debugger showed proper permissions. After I updated to new SDK, and figured out the new way to get a simple data list of permissions, everything worked again.
It took me a lot of digging in the FB website to find this solution, so I paste it here to hopefully save somebody else a few hours. They real life saver was my discovery of the getDecodedBody method (a very hard to find trick in FB docs). My example just checks for publish_actions.
$fb = new Facebook\Facebook([
'app_id' => your_app_id,
'app_secret' => your_secret,
'default_graph_version' => 'v2.2',
]);
$badperms=true; //start by assume bad permissions
try {
$response = $fb->get('/me/permissions', $at);
$perms = $response->getDecodedBody();
if($badperms){
foreach($perms['data'] AS $perm){
if($perm['permission']=='publish_actions' && $perm['status']=='granted') $badperms=false;
}
}
} catch(Facebook\Exceptions\FacebookResponseException $e) {
log("MSG-received facebook Response exception!! ".$e->getMessage());
} catch(Facebook\Exceptions\FacebookSDKException $e) {
log("MSG-received facebook SDK exception!! ".$e->getMessage());
}
if($badperms) {
//do something like reflow auth
}
I just had the same issue, I didn't know how to treat the cancel action (both in facebook php api and google oauth2).
The solution is much easier than expected.
The response in case of permission not accepted (at all) comes with at least one parameter/variable: error in the URL.
In facebook that response looks like:
error=access_denied&error_code=200&error_description=Permissions+error&error_reason=user_denied
for google you only get the
error=access_denied
but it should be enough.
I'm just checking if error is set and if it's set I am redirecting the response to my login page.
I hope it will help someone because it's really not documented this step.
By the way:
version of facebook API: v5
version of google API oAuth2: 2.0 (i think - google doc is really a mess when it comes to finding the latest versions)
how to post something on user wall ( may be a php processed image or something text ) when user clicks a button. As an example suppose a facebook user installs my app, then it shows some processed image then if the user wishes to publish he clicks the publish button and get published to his wall otherwise it will not. The difficulty I faced is to to go from one page to another ( as going from index.php to upload.php) ,transferring access_token,and how to make api call to upload the image from upload.php should i have to make upload.php as index.php so as it can re authenticate the user?
You sound really confused.
There should be no difference if you name your file index.phpor upload.php.
I don't see why you would need to manually take care of the access token. Use the PHP SDK, and it is done automatically for you. The PHP SDK uses the $_SESSION variable to store it. Otherwise, you could pass it in the URL as an argument like:
upload.php?access_token=SOMETHING_REALLY_SECRET
I'd not recommend that though, since it makes your site very vulnerable to attacks.
There is a complete example in the PHP SDK documentation:
<?
// 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',
'fileUpload' => true,
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
$photo = './mypic.png'; // Path to the photo on the local filesystem
$message = 'Photo upload via the PHP SDK!';
?>
<html>
<head></head>
<body>
<?
if($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 {
// Upload to a user's profile. The photo will be in the
// first album in the profile. You can also upload to
// a specific album by using /ALBUM_ID as the path
$ret_obj = $facebook->api('/me/photos', 'POST', array(
'source' => '#' . $photo,
'message' => $message,
)
);
echo '<pre>Photo 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.
$login_url = $facebook->getLoginUrl( array(
'scope' => 'photo_upload'
));
echo 'Please login.';
error_log($e->getType());
error_log($e->getMessage());
}
echo '<br />logout';
} else {
// No user, print a link for the user to login
// To upload a photo to a user's wall, we need photo_upload 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' => 'photo_upload') );
echo 'Please login.';
}
?>
</body>
</html>
So I have a Facebook Page (let's call it X), which has app Y on it. The user can ask a question via Y, and it gets posted to X as the user (not as the app).
My permissions for the app are currently set to publish_stream.
I can grab a token via
$token_url = "https://graph.facebook.com/oauth/access_token?" .
"client_id=" . $this -> data["environment"] -> fb_appid .
"&client_secret=" . $this -> data["environment"] -> fb_appsecret .
"&grant_type=client_credentials";
$app_token = file_get_contents($token_url);
which gives me a token just fine.
Now, if I try to POST via an APi call, I get two results:
When I do not pass the token and simply call
$post_id = $this ->Facebook->fb_api("/PAGE_ID/feed", "POST", array("message"=>"This is a post from PHP."));
I get a response back in the form of JSON
{
"id": "PAGEID_someOtherID"
}
but I do not see the post on the wall.
When I do pass the access token, ala
$post_id = $this ->Facebook->fb_api("/PAGE_ID/feed", "POST", array("access_token"=>$app_token,"message"=>"This is a post from PHP."));
my response comes back empty.
What am I doing wrong with such a simple concept?

Well you are not able to post something on a page wall without access_token Cause without access token facebook can not realize Who is The user who wants to post & about the time you are trying to post via access_token i think you are doing something wrong please check permissions you have (you need publish_stream not stream_publish) i will put a sample code for you soon
I know that there are lot's of questons on this, but all seem to be needing a user to be logged in... I have been using code snippets from all possible tutorials, but none seem to work.
Here is the scenario:
I have a photo community running on PHP and I have a fan page on Facebook. When an image on the main site collects a certain amount of votes a function is triggered to post the image link to the Facebook wall. The link (post) is posted as a page and not as admin. Admin of course will not be online... Is this even possible to do these days? I have the latest PHP SDK and this is the function that I need to get working in stand alone mode before pluggin' into the main site.
OK. This code works perfectly if I am logged into the Facebook, but if I am not - it will not post... The App has all necessary and unnecessary :) permissions to interact with my page on my (admin) behalf. Any ideas will be appreciated.
<?php
//facebook application
$fbconfig['appid' ] = "1848740815xxxxx";
$fbconfig['secret'] = "a5aa62bb3a8ddcb98d5d9dbe4a3xxxxx";
$fbconfig['pageid'] = "121409594622865";
$user = null; //facebook user uid
try{
include_once "facebook.php";
}
catch(Exception $o){
error_log($o);
}
// Create our Application instance.
$facebook = new Facebook(array(
'appId' => $fbconfig['appid'],
'secret' => $fbconfig['secret']
));
//Facebook Authentication part
$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'offline_access,publish_stream'
)
);
$logoutUrl = $facebook->getLogoutUrl();
$pageid = $fbconfig['pageid'];
if ($user) {
try {
$page_info = $facebook->api("/$pageid?fields=access_token");
if( !empty($page_info['access_token']) ) {
$args = array(
'access_token' => $page_info['access_token'],
'message' => 'This is a test feed message',
'link' => 'http://www.fotodvor.com',
'picture' => 'http://www.fotodvor.com/data/media/15/1319971991.jpg',
'name' => 'Test Picture',
'description'=> 'Description of the test picture!'
);
$post_id = $facebook->api("/$page_id/feed","post",$args);
}
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
