Request dialog - How to get the sender id - facebook

I'm using this below code so that i get hte request id when my friends accepts my invite but how do i get my uid.
Say I'm A.A sends invite to b.When b ,accepts ,i can get request id but how do i get A UID
//get the request ids from the query parameter
$request_ids = explode(',', $_REQUEST['request_ids']);
//build the full_request_id from request_id and user_id
function build_full_request_id($request_id, $user_id) {
return $request_id . '_' . $user_id;
}
//for each request_id, build the full_request_id and delete request
foreach ($request_ids as $request_id)
{
echo ("reqeust_id=".$request_id."<br>");
$full_request_id = build_full_request_id($request_id, $user_id);
echo ("full_request_id=".$full_request_id."<br>");
try {
$delete_success = $facebook->api("/$full_request_id",'DELETE');
if ($delete_success) {
echo "Successfully deleted " . $full_request_id;}
else {
echo "Delete failed".$full_request_id;}
}
catch (FacebookApiException $e) {
echo "error";}
}

When you make a GET call to /{request_id} you get back the sender and recipient uids

Try $user_id = $facebook->getUser();
edit: looking back at your code, I see you already use $user_id, so isn't that the ID you need?

Every time i have to remove app from account and re-authorized. I re-authenticated app still not get newly added business account.
Guys any solution for this ??

Facebook Graph Api error "An unexpected error has occurred. Please retry your request later"

I'm trying to retrieve all members in a Facebook group getting this error:
array(5) {
["message"]=>
string(66) "An unexpected error has occurred. Please retry your request later."
["type"]=>
string(14) "OAuthException"
["is_transient"]=>
bool(true)
["code"]=>
int(2)
["fbtrace_id"]=>
string(11) "AnfsXcdgM"
}
Here is my code:
$this->_facebook = new Facebook\Facebook(array('app_id' => "$app_id",'app_secret' => "$secret",'default_graph_version' => 'v2.10'));
$this->_facebook->setDefaultAccessToken($_SESSION['facebook_access_token']);
$query = "/".$groupID."/members?fields=id,name,link,picture,first_name,last_name";
try{
$response = $this->_facebook->get($query);
while($pagesEdge)
{
$pageDecoded = json_decode($pagesEdge);
foreach($pageDecoded as $key => $member)
{
$id = $member->id;
}
}
}catch (Facebook\Exceptions\FacebookResponseException $e) { echo 'Graph returned an error: ' . $e->getMessage(); }
It works for groups with few hundreads of people (even once for a group with 10.000 members) but randomly I'm occurring to this.
This might be caused by a server side timeout. I get this error every now and then when I request a huge amount of data. Maybe you should try to limit your request by using the limit parameter (default should be 25).
I solved this by doing a cron that takes 100 data at the time and putting into a file text the value of the token for the next call.
I add this string on the query and when the fields inside $url are empty I quit my execution
<?php
public function updateGroupMembers($groupID)
{
$tempNext = file_get_contents($this->dirM); //check if the next string token is in the file
if (!empty($tempNext))
{
$queryUntil = $tempNext;
}
// Sets the default fallback access token so we don't have to pass it to each request
$this->_facebook->setDefaultAccessToken($_SESSION['facebook_access_token']);
// Create table name
$tableName = $groupID . "_Members";
// Query the Graph API to get all current member's ID and name
try
{
$query = "/".$groupID."/members?fields=id,name,link,picture,first_name,last_name".$queryUntil; //add the next string to my query
$response = $this->_facebook->get($query);
$pagesEdge = $response->getGraphEdge();
// Index for the elements fetched from the API below
$i = 0;
// Get current time
$pageDecoded = json_decode($pagesEdge);
foreach($pageDecoded as $key => $member)
{
/* ...get data and process them... */
}
$temp = $pagesEdge->getMetaData();
$next = parse_url($temp['paging']['next']);
parse_str($next['query'], $url);
$access_token = '&access_token='.$url['access_token'];
$fields = '&fields='.$url['fields'];
$limit = '&limit=100';
$after = '&after='.$url['after'];
$res['until'] = $access_token.$fields.$limit.$after;
file_put_contents($this->dirM, $res['until'], LOCK_EX);
if ( empty($url['access_token']) || empty($url['fields']) || empty($url['limit']) || empty($url['after']) )
{
file_put_contents($this->dirM, '', LOCK_EX); //clean my txt file that contains my next string
die('FINE');
}
} catch (Facebook\Exceptions\FacebookResponseException $e) {
echo 'm2Graph returned an error: ' . $e->getMessage();
exit;
} catch (Facebook\Exceptions\FacebookSDKException $e) {
echo 'm2Facebook SDK returned an error: ' . $e->getMessage();

Code to access Facebook Graph API with PHP SDK not working when reloading page

I'm writing some code to get the Facebook pages administered by a Facebook user, using Facebook Graph API. My code asks for authorization of the user and gets a token that enables it to get this information, which is then stored in a session. The problem is that if I reload the page, the stored token is unset and I will not be able to get the Facebook pages administered by the Facebook user.
The token is apparently revoked via the 'validateExpiration()' function when the page is reloaded.
What am I missing?
Here is my code:
session_start();
// Load the Facebook PHP SDK
require_once __DIR__ . '/facebook-sdk-v5/autoload.php';
define('APP_ID', 'xxxxxxxxxxxxxxxx');
define('APP_SECRET', 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');
$fb = new Facebook\Facebook([
'app_id' => APP_ID,
'app_secret' => APP_SECRET,
'default_graph_version' => 'v2.7'
]);
if(isset($_SESSION['fb_access_token'])) {
echo '$_SESSION["fb_access_token"] = ' . $_SESSION['fb_access_token'] . '<br>';
// Create a new AccessToken object from its string code. Needed?
$accessToken = new Facebook\Authentication\AccessToken($_SESSION['fb_access_token']);
$expirationDate = $accessToken->getExpiresAt();
echo 'Token expires at: ' . var_dump($expirationDate) . '<br>'; // Returns null!
// verifies the validity and expiration of the token
$oAuth2Client = $fb->getOAuth2Client();
$tokenMetadata = $oAuth2Client->debugToken($accessToken);
try {
echo 'Validating token<br>';
$tokenMetadata->validateAppId(APP_ID);
$tokenMetadata->validateExpiration(); // This apparently throws an exception
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'I will now unset the token<br>';
unset($accessToken);
unset($_SESSION['fb_access_token']);
}
if(!isset($accessToken)){
echo 'Token not set!';
exit;
}
// Check permissions
if (isset($accessToken)) {
$response = $fb->get('/me/permissions', $accessToken);
$permissions = $response->getDecodedBody();
echo 'Permissions: ';
print_r($permissions);
$permissions_list = [];
foreach($permissions['data'] as $perm) {
if($perm['status'] == 'granted') {
$permissions_list[] = $perm['permission'];
}
}
echo 'Permissions list: ';
print_r($permissions_list);
if(!in_array('pages_show_list', $permissions_list)) {
echo 'I will now unset the token<br>';
unset($accessToken);
unset($_SESSION['fb_access_token']);
}
}
} else {
$helper = $fb->getRedirectLoginHelper();
try {
$accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
}
if(isset($accessToken)) {
// Logged in!
// Save the string code of the AccessToken to re-create it later
$_SESSION['fb_access_token'] = (string) $accessToken;
echo '$_SESSION["fb_access_token"] = ' . $_SESSION['fb_access_token'] . '<br>';
try {
$response = $fb->get('/me/accounts', $accessToken);
$data = $response->getDecodedBody();
echo '<pre>';
print_r($data);
echo '</pre>';
exit;
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
} else {
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email', 'public_profile','pages_show_list']; // Optional permissions
$redirect_url = "https://www.example.com/this_file.php";
$loginUrl = $helper->getLoginUrl($redirect_url, $permissions);
echo 'Log in with Facebook!';
}
I finally got it!
The problem is that the Facebook AccessToken is an object with two properties: a string code, and a datetime PHP object with the expiration time - see the code in:
Github repository of Facebook's PHP SDK. The first time I get a fresh token, its expiration time is set and everything works fine. But when I store its code in a session and try to recreate it with
$accessToken = new Facebook\Authentication\AccessToken($_SESSION['fb_access_token']);
I'm not setting the expiration time, which the object defaults to the UNIX time 0 (i.e. January 1, 1970). Since after I invoke the function validateExpiration(), this will return that the access token has expired (it just looks at the expiration time in the AccessToken object) and will fire an exception.
Solution: Do not re-validate the stored token. The validateAppId(APP_ID) continues to be valid. For the expiration time, either store it (for example in a session) and use it when recreating the AccessToken object, or make a call to the Graph API. If this call returns an error (probably because of a token which was expired or a permission which was revoked by the user), ask the user for a new token via Facebook Login.

Laravel, Facebook API: retrieving friends of friends

In a previous thread we were strugling with the Facebook login using a Laravel app. Now, as the user logs into our app using Facebook, we are trying to get his friend's list in order to provide some qualified suggestions. So, here's what we are trying:
Route::get('login/fb/callback', function() {
// A FacebookResponse is returned from an executed FacebookRequest
$helper = new FacebookRedirectLoginHelper('http://yoururl/login/fb/callback');
$session = $helper->getSessionFromRedirect();
$request = new FacebookRequest($session, 'GET', '/me/friends');
try {
$response = $request->execute();
$me = $response->getGraphObject();
} catch (FacebookRequestException $ex) {
echo $ex->getMessage();
} catch (\Exception $ex) {
echo $ex->getMessage();
}
print_r($me);//->getProperty("id"));
$user = new Giftee;
$user->name = $me->getProperty('first_name') . ' ' . $me->getProperty('last_name');
$user->email = $me->getProperty('email') . "#facebook.com.br";
$user->photo = 'https://graph.facebook.com/' . $me->getProperty('id') . '/picture?type=large';
$user->save();
});
As a result, we get:
object(Facebook\GraphObject)#146 (1) { ["backingData":protected]=> array(0) { } }
By reading the Facebook API docs, they pretty much say user_friends will only return friends of friends that already use your app and We could not see any login permission that would just return friends of friends (not only the ones using our app). In another words, is what we want really impossible?
You're not able to retrieve friends of friends. With Graph API v2.0, you even only get those friends of your app's users which also use your app.
And, all friends_* permissions have been removed. So I don't see a chance for you to implement what you want to achieve.

Fetching friends' birthdays from facebook profile

I want to fetch 'birthdays' of users, and their friends on my website, from their facebook profiles (with their facebook credentials supplied).
Is their a feature in Facebook API/Connect that I can use to fetch these details from facebook as possible on Native Facebook Apps using Facebook API.
I want to store this data in my DB, and users will be asked for their facebook credentials and consent before this is done.
Read the api documentation things like this are easily done. You can do it like this:
$facebook = new Facebook( $apikey, $secret );
$uid = $facebook->require_login();
$friends = $facebook->api_client->friends_get(); // $friends is an array holding the user ids of your friends
foreach( $friends as $f ) {
$data = $facebook->api_client->fql_query( "SELECT birthday_date FROM user WHERE uid=$f" );
// $data[0] is an array with 'birthday_date' => "02/29/1904"
// see api documentation for other fields and do a print_r
}
So recently I wanted to check my friends to see if any of them had their birthday for the current day. Using FQL this is super easy and I encourage you to explore FQL more because it will yield a more efficient solution than, say, what Pierre kindly offered. Here is a small snippet of the code:
$friends = $facebook->api_client->friends_get();
$uids = "";
foreach($friends as $f) {
$uids .= "uid=$f OR ";
}
$query_uids = substr($uids,0,strlen($query_uids)-4);
date_default_timezone_set('UTC');
$current_date = date("m/d");
echo "<br />Searching for birthdays for the given month/day: $current_date<br />";
$data = $facebook->api_client->fql_query( "SELECT name, uid FROM user WHERE ( ($query_uids) AND strpos(birthday_date,'$current_date') >= 0 )" );
if(count($data) > 0) {
foreach($data as $d) {
print_r($d);
}
} else {
echo "<br />No Birthdays Today<br />";
}
require_once('facebook-platform/client/facebook.php');
$facebook = new Facebook(API_KEY, SECRET);
$facebook->require_login();
function getInfo($user_list, $fields)
{
try
{
$u = $facebook->api_client->users_getInfo($user_list, $fields);
return $u;
}
catch (FacebookRestClientException $e)
{
echo $e->getCode() . ' ' . $e->getMessage();
}
}
function getFriendsBirthdays($user_id)
{
$f = $_REQUEST['fb_sig_friends'];
$f = explode(',', $f);
$birthdays = array();
foreach($f as $friend_id)
{
$birthdays[] = getInfo($friend_id, 'birthday');
}
return $birthdays;
}
Do something like that or use the Batch API to do multiple calls at once. Check the Facebook API.
You could fetch it via the API, but Facebook's terms strictly forbid you from storing anything other than their user ID in your database - see the developer wiki for details. You will need to query the API each time.
