Direct access after authentication insteed iframe access - php

When the user authorize my app, he is redirected to my site and not to facebook with my app in the iframe. Is there a way to stay in facebook ?
My code :
require './src/facebook.php';
$config = array();
$config['appId'] = 'XXXXX';
$config['secret'] = 'XXXXX';
$config['fileUpload'] = false; // optional
$facebook = new Facebook($config);
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
echo "blah";
} else {
$params = array(
'scope' => 'read_stream, friends_likes',
'redirect_uri' => 'https://xxxxx'
);
$loginUrl = $facebook->getLoginUrl($params);
echo("<script> top.location.href='" . $loginUrl . "'</script>");
}
?>

Try putting your app's url (http://apps.facebook.com/your_app_namespace) in the redirect_uri param. This should fix the issue you are facing.

URI blocked while login with Facebook in PHP

URL Blocked: This redirect failed because the redirect URI is not
whitelisted in the app’s Client OAuth Settings. Make sure Client and
Web OAuth Login are on and add all your app domains as Valid OAuth
Redirect URIs. The above error shown in while i press login with
facebook
in valid outh http://www.example.com/the78/login-facebook.php
and all the process in my side is handle on the same url.
<?php
require 'facebook/facebook.php';
require 'fbconfig.php';
require 'functions.php';
$facebook = new Facebook(array(
'appId' => APP_ID,
'secret' => APP_SECRET,
));

}
if (!empty($user_profile )) {
die('we are in ');

$username = $user_profile['name'];

$_SESSION['oauth_id'] = $uid;
$_SESSION['username'] = $userdata['username'];
$_SESSION['email'] = $email;
$_SESSION['oauth_provider'] = $userdata['oauth_provider'];
echo ("<script>location.href='users/home.php'</script>");
}
} else {
# For testing purposes, if there was an error, let's kill the script
die("There was an error.");
}
} else {
# There's no active session, let's generate one
$login_url = $facebook->getLoginUrl(array( 'scope' => 'email'));
// header("Location: " . $login_url);
echo ("<script>location.href='$login_url'</script>");
}
?>
This is the facebook url which shows error
https://www.facebook.com/dialog/oauth?client_id=1575902869377664&redirect_uri=http%3A%2F%2Fexample.com%2Fthe78%2Flogin-facebook.php&state=f80b87f59baa9ca6ec69733e55b227f0&scope=email

Facebook re-authentication

I'm using PHP SDK to authentication and requesting permissions.
$facebook = new Facebook(array(
'appId' => '7xxx349xx',
'secret' => 'x0b360034c9exxxx4f',
'cookie' => true
));
$params = array(
'scope' => 'publish_actions, read_friendlists',
'redirect_uri' => 'example.com',
);
$user = $facebook->getUser();
$usertoken = $facebook->getAccessToken();
if ($user) {
try {
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
header("Location: xxx.php");
}
if(!$user) {
//$statusUrl = $facebook->getLoginStatusUrl();
$loginUrl = $facebook->getLoginUrl($params);
}
It works well but if user delete app in privacy settings and try to login again I have errors:
CSRF state token does not match one provided.
OR
OAuthException: Error validating access token: The user has not authorized application [APPID]
How to fix it? I need additional code?
Thanks for help

Facebook redirect url to index.php

index.php

$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'email,offline_access,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown,user_photos ,user_work_history'

}
//if user is logged in and session is valid.
if ($user) {
//get user basic description
$userInfo = $facebook->api("/$user?fields=picture,name,email,gender,birthday");

$_SESSION['name'] = $res['name'];
$_SESSION['email'] = $res['email'];

For the 1st time I am working on the Facebook app. I have made app on the Facebook developer. It's working properly but it is not redirecting me in the index.php. I want to redirect it in this page only so all the values are stored in the session and I am checking it if the cookies is made then this value is going to registration.php and if not then its going to sbs_login.php. Please can anybody tell where to give the redirect url?
$loginUrl = $facebook->getLoginUrl(array(
'baseurl' => $fbconfig['baseurl'],
'scope' => 'email,offline_access,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown,user_photos ,user_work_history'
));
I find the solution of my problem . so this is the solution
$loginUrl = $facebook->getLoginUrl(array(
'baseurl' => $fbconfig['baseurl'],
'scope' => 'email,offline_access,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown,user_photos ,user_work_history'

Php with Facebook SDK don't load page

I use this code to take information about people friends with Facebook
:
require 'facebook-php-sdk-master/src/facebook.php';
$app_id = 'xxxxxxx';
$app_secret = 'xxxxxxxx';
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
));
$user = $facebook->getUser();
if ($user) {
try {
$user_profile = $facebook->api('me/friends');
print_r($user_profile);
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
} else {
$params = array(
'scope' => 'user_birthday',
);
$loginUrl = $facebook->getLoginUrl($params);
echo("<script> top.location.href='" . $loginUrl . "'</script>");
}
?>
But now, a lot of time, when i try to load this , i see that in the url the param "code" start to change a lot of time and the page don't load. What kind of problem is that?
$user is false in your code for some reason (always). May be the facebook user didn't accept your app. $facebook->getLoginUrl($params); redirects to the request uri, with $user false the request uri redirects to $loginUrl. This cause an endless loop.

Login with facebook is not working properly

I am using facebook api for using login functionality of facebook on my website. But there is a problem with it, it does not redirected to my website after login. It redirects to facebook home page. I don't know why it happens. My code is below:
This file name is logign_facebook.php

die("There was an error.");
}
} else {
# There's no active session, let's generate one
$login_url = $facebook->getLoginUrl(array( 'scope' => 'email'));
header("Location: " . $login_url);
}
?>
Please help me to fix this issue.
Thanks
Facebook needs to know the URL to redirect back to when the user has logged in.
You can pass this through the the getLoginUrl() function in the PHP SDK as below:
$login_url = $facebook->getLoginUrl(array(
'redirect_uri' => 'http://yoururlhere.com/logign_facebook.php',
'scope' => array('email')
));
A full list of parameters for this function can be seen at https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl.
Another solution:
https://developers.facebook.com/apps/
Apps>>[app_name]>>basic
And scroll down to the "Website with Facebook Login"
Enter your desired URL in the textfield.
