I tried to build facebook game but I stuck in saving score.
I have tried exactly as written in http://developers.facebook.com/docs/guides/games/getting-started/#step4 but It just simply wouldn't save the score.
I thought the problem is in this listing :
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
));
$user = $facebook->getUser();
print('user : '.$user.' ');
there is always 0 although my fb account had logged in. With this problem I couldn't save nor update the high score. I need help to find the way to retrieve the $user.
I really appreciate every favor to me. Thank you...
Do you have this part?
// If the user has not installed the app, redirect them to the Auth Dialog
if (!$user) {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => $scope,
'redirect_uri' => $app_url,
));
print('<script> top.location.href=\'' . $loginUrl . '\'</script>');
}
Its required to log user and get his data.
Here is good explanation http://developers.facebook.com/docs/authentication/server-side/

devs,
so I have been struggling with this problem for about 10 hours now, and I can't seem to find a solution online, worst is that I don't even know why it happens.
I am working on a project which uses PHP LARAVEL as the backend and I started writing the API for the flutter frontend to consume then I ran into this error while trying to test the API endpoint for registering and logging in.
The problem is the process fails with this error when I try to generate or create a token for the registered user or logged-in user.
Here a snapshot of my register function
public function store(Request $request)
{
$validated = Validator::make($request->all(),[
"email" => "required|email",
"password" => 'required',
"first_name"=> "required",
"last_name" => "required",
"phone_number" => 'required',
]);
if ($validated->fails()) {
return response()->json(['errors' => "Invalide credentials"], 403);
}
$user = User::create(
// [
// 'first_name' => $request->first_name,
// 'last_name'=> $request->last_name,
// 'email' => $request->email,
// 'password' => bcrypt($request->password),
// 'phone_number' => $request->phone_number,
// ]
$request->toArray()
);
Auth::guard('api')->check($user);
// $newUser = User::find($user->id);
$token = $user->createToken('authToken')->accessToken;
// return $token;
return response(['token' => $token, 'first_name'=>$user->first_name, 'email'=>$user->email ], 200);
}
The login and register functions all look the same at this point.
Error-causing code is :
$token = $user->createToken('authToken')->accessToken;
Please I am open to your suggestions, thanks.
I finally found a solution for this error and I believe it will help anyone out there with a similar problem.
The problem originates from the fact that your application is unable to asign a unique id to your client, remember your website or mobile app is a client to the backend with also(your mobile app or website) might have other users, so laravel passport will need to identify it with a unique id, below are some of the steps i used to fix this error.
First it originates because during the passport installation, i forgot to install
Blockquote
--uuids
If you have a similar error, follow the steps below to fix:
NOTE: You must have laravel passport installed already, if not, them follow the complete installtion guide Here
Step 1:
Install passport uuids
php artisan passport:install --uuids
Your result will look something like
After creating, the uuid for your application, you will have to include it in your .env file as such:
PASSPORT_PERSONAL_ACCESS_CLIENT_ID=986eb40c-0458-4b6e-bead-ea2fc4987033
PASSPORT_PERSONAL_ACCESS_CLIENT_SECRET=VXLdTpqWK9i3CBqFwZgje5fuerQ5Uf2lvwXJqBoP
And there you go, you can now try to do what you couldn't do before.
I am looking for an example for web push notification with JS code and PHP backend. Can anyone share example code or a tutorial?
Here's a basic example that uses web-push-php : https://github.com/Minishlink/web-push-php-example
Main PHP code is:
<?php
require __DIR__ . '/vendor/autoload.php';
use Minishlink\WebPush\WebPush;
$auth = array(
'VAPID' => array(
'subject' => 'https://github.com/Minishlink/web-push-php-example/',
'publicKey' => 'BCmti7ScwxxVAlB7WAyxoOXtV7J8vVCXwEDIFXjKvD-ma-yJx_eHJLdADyyzzTKRGb395bSAtxlh4wuDycO3Ih4',
'privateKey' => 'HJweeF64L35gw5YLECa-K7hwp3LLfcKtpdRNK8C_fPQ', // in the real world, this would be in a secret file
),
);
$webPush = new WebPush($auth);
$res = $webPush->sendNotification(
$subscription['endpoint'],
"Hello!", // payload
$subscription['key'],
$subscription['token'],
true // flush
);
// handle eventual errors here, and remove the subscription from your server if it is expired
Hope this helps :)
(All URLs excluded "http://" as I've got insufficent reputation... sorry)
I've successfully do log in with facebook account in my website.
But it only work in index page only. (The URL matched with the facebook app website setting)
example:
The website url setting in the facebook app is : www.abc.com
The login work in the page: www.abc.com
BUT not work in www.abc.com/XXX
$facebook = new Facebook(array(
'appId' => 'XXXX',
'secret' => 'YYYY'
));
$facebook_user = $facebook->getUser();
var_dump($facebook_user);
//return user information in http://www.abc.com
//BUT return 0 in http://www.abc.com/XXXX
Any advise? Thanks a lot.
If you edit code that can solve the problem;
$facebook = new Facebook(array(
'appId' => 'XXXX',
'secret' => 'YYYY',
'cookie' => true,
));
best regards.
i am building a fan gate for my site to give out some coupon.
here is my code:
<?php
require_once 'facebook.php';
$app_id = "xxxxxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
print_r($_REQUEST);
$signed_request = $facebook->getSignedRequest();
echo "<pre>";
print_r($facebook->getSignedRequest());
echo "</pre>";
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
$like_status = $signed_request["page"]["liked"];
print_r($facebook);
?>
I find that the return value of $facebook->getSignedRequest(); is different when i am visiting my apps via apps.facebook.com/xxxxxxxxxxxxxxxxxxxxxx/ and when i am visiting www.coupon.mysite.com/facebook/index.php
via apps.facebook.com/xxxxxxxxxxxxxxxxxxxxxx/:
Facebook Object ( [appId:protected] => 15255288xxxxxxxx [appSecret:protected] => XXXXXXXXXXXXXXXXXXXX[user:protected] => [signedRequest:protected] => Array ( [algorithm] => HMAC-SHA256 [issued_at] => xxxxxxxxxxxxx[user] => Array ( [country] => hk [locale] => en_US [age] => Array ( [min] => 21 ) ) ) [state:protected] => [accessToken:protected] => [fileUploadSupport:protected] => )
via www.coupon.mysite.com/facebook/index.php:
Facebook Object ( [appId:protected] => xxxxxxxxxxxxxxxxxxx[appSecret:protected] => xxxxxxxxxxxxxxxxxx[user:protected] => [signedRequest:protected] => [state:protected] => [accessToken:protected] => [fileUploadSupport:protected] => )
so the fan gate wont work because $facebook->getSignedRequest(); always return null in my server side. I have do the searching for this problem for some days already and still dont understand what is the problem.
Any help is very much appreciated.
^ ... continue from the comments:
First of all, if you do this, your users will hate you; secondly, that plugin is bit of a scam - all it does is uses cookies to store if user has liked a page - but if you delete your cookies, you will be locked out of the content because you won't be able to like the page again. Furthermore, it won't work without Javascript.
All the plugin does is it hooks into the "like" action when user clicks on the like button via
FB.Event.subscribe('edge.create', function(href, response){});
facebook graph api determine if user likes url
I can use the following code to redirect a user back to the page my app is installed on using the following code:
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
$signed_request = $facebook->getSignedRequest();
$page = $signed_request['page'];
$page_id = $page['id'];
$page_array = $facebook->api("/$page_id");
$page_link = $page_array['page_link'];
$redirect_uri = $page_link . '?sk=app_' . $app_id
$user = $facebook->getUser();
if(!$user) {
$url = $facebook->getLoginUrl(array('redirect_uri' => $redirect_uri));
echo "<script type='text/javascript'>top.location.href = '$url';</script>";
}
This works fine for most pages but if a page has age restrictions (and I cant guarantee all the pages using my app won't) the $facebook->api("/$page_id"); returns false because from what I can gather, I need the users access token in order to get this information which I can't get unless I authenticate them! Is there any way around this paradox or am I going to have to instruct my users not to age restrict their pages?
UPDATE
I realise I can simply redirect to facebook.com/$page_id which will take the user back to the page after authentication and would save me having to make the api request for $page_link but ideally I would like them to be redirected to my apps page tab on that page no matter what the specified default landing tab is.
