Api of facebook is blinking when getting user information

Currently make the connection to the facebook api with php, create a project in facebook developers, generate the corresponding keys and as for the permissions of users I'm using the default and the permission of the mail, allows me to enter and give permission to the application but sometimes does not bring all the user information and some times when you click the button facebook does not open the popup to log in with facebook or give permission to the application with my account, sometimes if not, I do not know why and the case is still very intermittent, in the browser console does not tell me that is due to the intermittence, something important to mention is that the day if there is a high flow of people trying to use the login with facebook but the intermittent can not be logged in, I have this script in html before the body:
window.fbAsyncInit = function () {
FB.init({
appId: '<?php echo $UrlApiFacebook; ?>',
cookie: true, // Enable cookies to allow the server to access the session.
autoLogAppEvents : true,
xfbml: true, // Parse social plugins on this webpage.
version: 'v7.0' // Use this Graph API version for this call.
});
};
(function(d, s, id) { // Load the SDK asynchronously
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "https://connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
function checkLoginState() {
FB.getLoginStatus(function (response) { // Called after the JS SDK has been initialized.
statusChangeCallback(response, 1); // Returns the login status.
});
}
For this code I rely directly on the official documentation of facebook developer, in another javascript file is the function 'statusChangeCallback()' this file is like this:
function statusChangeCallback(response, i) {
console.log('statusChangeCallback');
console.log(response);
if (i == 3) {
if (response.status === 'connected') { // Logged into your webpage and Facebook.
FB.logout(function (response) {
window.location.href = "login_out.php";
});
} else {
window.location.href = "login_out.php";
}
} else {
if (response.status === 'connected') { // Logged into your webpage and Facebook.
testAPI();
} else { // Not logged into your webpage or we are unable to tell.
console.log("No logueado");
FB.login(function (response) {
if (response.status === 'connected')
testAPI();
});
}
}
}
function testAPI() { // Testing Graph API after login. See statusChangeCallback() for when this call is made.
console.log('Welcome! Fetching your information.... ');
FB.api('/me', { fields : 'name,picture,first_name,last_name,email' }, function (response) {
console.log('Successful login for: ' + response.name);
onSendDataFacebook(response);
});
}
function logoutUserFacebook() {
FB.getLoginStatus(function (response) { // Called after the JS SDK has been initialized.
statusChangeCallback(response, 3); // Returns the login status.
});
}
function onSendDataFacebook(userFacebook) {
let email = "";
let name = "";
let last_name = "";
var user = {
id: userFacebook.id, nombre: userFacebook.name,
email: userFacebook.email,
nombrecompleto: userFacebook.first_name + ' ' + userFacebook.last_name,
llamado: redir,
veces: x
}
if(!userFacebook.email){
user.email = email;
}
if(!userFacebook.name){
user.name = name;
}
if(!userFacebook.first_name || !userFacebook.last_name){
user.first_name = name;
user.last_name = last_name;
}
redireclogin(user);
}
I would very much appreciate the help of anyone who knows what this intermission is about, thank you in advance.

Track canceled facebook login

I wish to track users which were presented with the Facebook Login dialog popup, and chose to close it (by clicking "cancel" or just closed the popup window).
I am using Facebook SDK and invoking FB.login()
From the docs it's unclear, but it does appear there might be some way to track this, so, if anyone here knows how, or can help, it would be appriciated. Thanks!
complete code:
var facebook = (function(){
// Configuration
var serverDomain = '365scores.com',
appID = '158698534219579';
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
window.fbAsyncInit = function(){
FB.init({
appId : appID,
cookie : true, // enable cookies
xfbml : true, // parse social plugins on this page
version : 'v2.0' // use version 2.0
});
FB.getLoginStatus(FBLoginStatus);
FB.Event.subscribe('auth.authResponseChange', FBLoginStatus);
};
function FBLoginStatus(response){
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if( response.status === 'connected' ){
// Logged into your app and Facebook.
//connected(response);
$(document).trigger('connection', ['facebook', response]);
}
else if( response.status === 'not_authorized' ){
// The person is logged into Facebook, but not your app.
}
else{
// The person is not logged into Facebook, so we're not sure if
// they are logged into this app or not.
}
};
function checkLoginState() {
FB.getLoginStatus(function(response) {
FBLoginStatus(response);
});
}
function connected(res){
console.log( res )
console.log('FACEBOOK CONENCTED');
/*
FB.api('/me', function(response){
});
*/
}
return FBLoginStatus;
})();

FB.login(function(response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
} else {
console.log('User cancelled login or did not fully authorize.');
}
});

How to redirect user after facebook login

I am developing a game which requires user to login and then uses the login details to update the leaderboard. But the problem is that after the user logs in, the login dialog does not get closed automatically and the user is not redirected to the game. Here is the code which is taken from here
window.fbAsyncInit = function() {
FB.init({
appId : 'XXXXXXXXXX',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.Event.subscribe('auth.authResponseChange', function(response) {
shepResponse = response;
// Here we specify what we do with the response anytime this event occurs.
if (response.status === 'connected')
testAPI();
}
else if (response.status === 'not_authorized') {
FB.login();
} else {
FB.login();
}
});
};
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "http://connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
}

try not wrapping FB.Event.subscribe and testAPI() inside the fbAsyncInit function.
Also try auth.statusChange instead of auth.authResponseChange
var fb_handleStatusChange = function(response) {
if (response.authResponse) {
// user logged in
} else {
// not logged in or logged out
}
}
FB.Event.subscribe('auth.statusChange', fb_handleStatusChange);
Also, i think that the login redirect should be to a page that has this code and is listening for status change. I would not redirect back to the same page as the one used for login.

FB.getLoginStatus is not firing even the sandbox settings are off

I'm using the Facebook API in order to check if the user who visits my page is logged into Facebook or not. I tried everything, couldn't came up with a solution. I would like to especially state that sandbox mode is off. And my code is right below;
<div id="fb-root"></div>
<script>
function fbLoginStatus(response) {
console.log("Status: "+response.session);
if(response.session) {
//user is logged in, display profile div
alert("Logged in");
} else {
//user is not logged in, display guest div
alert("Not logged in");
}
}
window.fbAsyncInit = function() {
FB.init({
appId : '111111111111111', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.getLoginStatus(function(response){
console.log("Hey");
if(response.session){
console.log("You are logged in");
}
else{
console.log("You are not logged in");
}
});
// Additional initialization code here
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "http://connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>

FB.getLoginStatus is the function that is used to detect if user is logged into FB or not. In the callback of function you are checking response.session but as per my understanding this session is not a valid attribute of returning JSON object. You should use response.status. So code will become like below.
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
alert("LOG IN");
} else if (response.status === 'not_authorized') {
// the user is logged in to Facebook,
// but has not authenticated your app
} else {
// the user isn't logged in to Facebook.
}
});
Hope this Helps

JavaScript SDK Facebook: Trouble With Init Script

Trying to figure out how to use the JavaScript SDK. I'm new to JavaScrip. I was able to use the PHP SDK but want to run my stuff clientside. Anyhoo, I don't really understand the SDK documentation on the develop site. So the base code is:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'YOUR_APP_ID', // App ID
channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Additional initialization code here
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
Which I think I understand...it loads the SDK and then runs the FB.init stuff once it loads. I don't know where to put all of the OAuth stuff though, and how to structure the login request (i.e. if not logged in the make a button and if you are then return access token etc.
Can someone hold my hand through this beginning part. I've searched everywhere and I just don't quite get it.
Edit:
Okay, second try with authentication. Didn't work:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'XXX', // App ID
channelUrl : 'XXX', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Additional initialization code here
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
// the user is logged in and connected to your
// app, and response.authResponse supplies
// the user's ID, a valid access token, a signed
// request, and the time the access token
// and signed request each expire
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
FB.api('/me', function(response) {
alert(response.name);
});
} else if (response.status === 'not_authorized') {
FB.login(function(response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
FB.logout(function(response) {
console.log('Logged out.');
});
});
} else {
console.log('User cancelled login or did not fully authorize.');
}
}, {scope: 'email'});
} else {
}
})
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
Thanks!

Just below this line,
// Additional initialization code here
is where the oauth stuff goes.
I would suggest getting used to calling FB.getLoginStatus() first. See: http://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus/
EDIT
based upon the question edit above
This should be done inside the window.fbAsyncInit function
FB.api('/me', function(response) {
alert(response.name);
});
and only after you've checked the getLoginStatus() so you know if the person is logged in or not.
