I'm trying to enable Facebook login to my site via Javascript but when the user logs in, the Facebook popup doesn't closes. Instead it shows the following message:
An error may have occurred as part of the login process. You can close this window and try returning to the application, though it may ask you to login again. This is likely due to a bug in the application.
If I click again on the login button, everything works fine.
This is my code:
// 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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
// Init the SDK upon load
window.fbAsyncInit = function() {
var doLogin = function (response) {
url = '//'+window.location.hostname+'? access_token='+response.authResponse.accessToken;
window.top.location = url;
};
FB.init({
appId : 'MY_APP_ID', // App ID
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
oauth : true,
channelUrl : '//'+window.location.hostname+'/static/html/channel.html'
});
FB.Event.subscribe('auth.login', function(response) {
doLogin(response);
})
FB.getLoginStatus(function(response) {
if (response.status == 'connected') {
doLogin(response);
}
}, true);
}
You should try something like this:

Or you could replace AuthorizeFacebook with "FB.login" from the JS API

I can't seem to get the permissions for my facebook connection. Here's what I have:
window.fbAsyncInit = function() {
FB.init({
appId : 'myID', // App ID
channelUrl : 'myChannel', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
oauth : true
});
FB.Event.subscribe('auth.authResponseChange', function(response) {
if (response.status === 'connected') {testAPI();}
if (response.status === 'not_authorized') { FB.login(function(response) {}, {scope: 'email,user_likes'});}
else { FB.login(function(response) {}, {scope: 'email,user_likes'});}
});
};
(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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
When I hit my login button it asks:
MyApp would like to access your public profile and friend list.
What have I done wrong?
When you set the scope you are not giving permissions to the app. You are only telling that permissions that your app will need.
When you click in the login button for the first time, that dialog saying that "MyApp would like to access your public profile and friend list." appear. You need to confirm that you grant that permissions to your app by clicking in the ok button or similar in that dialog.
You should not need to to this again unless you change your application id or key or you manually revoke the authorization for that app in the facebook settings.
I have implemented a simple facebook login script for my facebook page tab app. It supposes to authenticate the app to the user. It works fine in all browsers, but IE (I have IE10 for testing the compatibility). In IE it brings the authentication pop-up as it intended and user can authenticate it just fine, but then instead of opening the main app page (liked.php) as it does in other browsers it keeps reloading itself (login.php). I know no one should be using IE in our days, but some people does and I need it to work even for them:)
Thank you! The code is here:
<body>
<div id="fb-root"></div>
<fb:login-button size="medium" onlogin="login()" scope="email, user_birthday">Logga in med Facebook</fb:login-button>
<script>
// Additional JS functions here
window.fbAsyncInit = function() {
FB.init({
appId : 'myid', // App ID
channelUrl : '//www.mydomain.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 init code here
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
// connected
} else if (response.status === 'not_authorized') {
// not_authorized
//login();
} else {
// not_logged_in
//login();
}
});
};
// 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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function login() {
FB.login(function(response) {
if (response.authResponse) {
// connected
window.location = 'liked.php';
} else {
// cancelled
}
});
}
</script>
</body>
And this is the answer to my problem which as I noticed most Facebook connect solutions for tab apps (iframe in FB) have in IE10:

I'm using Parse Javascript SDK to authenticate to Facebook and even though I get a success after login, my Facebook session is not created. Here is the code I use,
<div id="fb-root"></div>
<script>
// Additional JS functions here
window.fbAsyncInit = function() {
Parse.FacebookUtils.init({
appId : 'xxxx', // Facebook App ID
// channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow Parse to access the session
xfbml : true // parse XFBML
});
};
// 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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function fLogin() {
Parse.FacebookUtils.logIn(null, {
success: function(user) {
alert("login success with user " + JSON.stringify(user));
if (!user.existed()) {
alert("User signed up and logged in through Facebook!");
} else {
alert("User logged in through Facebook!");
}
//FB.api('/me', function(response) {
// alert("got fb me api=" + JSON.stringify(response));
//});
},
error: function(user, error) {
alert("User cancelled the Facebook login or did not fully authorize.");
}
});
}
</script>
<button class="btn-facebook btn-large" onclick="fLogin();"><img src="./img/fb_icon.png"> <span class="btn-facebook-text">Login with Facebook</span></button>
After the popup window opens and I log into Facebook, I get the console message "login success with user " and I can see the access token. However when I try to call FB.api ("/me")... I get an error saying Invalid access token from Facebook.. And When I go back to Facebook, I see that it didn't log me into Facebook either...
If I replace this whole code with FB.init() and FB.login() it works just fine.. Its when I replace it with Parse FacebookUtils that I get the error.
Any help will be greatly appreciated.
I have a problem with the authenticated referrals in the Auth Dialog. When a user uses the app for the first time and is requesting authorization, he/she gets "The App will receive: Your basic data." which is different from what is displayed when I preview the Auth Dialog in Facebook developer Apps site. I use the following code:
<script>
// 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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
// Init the SDK upon load
window.fbAsyncInit = function() {
FB.init({
appId : '<%= Facebook::APP_ID %>', // App ID
channelUrl : '//'+window.location.hostname+'/channel', // Path to your Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
url = '<%= users_path %>'
// listen for and handle auth.statusChange events
FB.Event.subscribe('auth.statusChange', function(response) {
if (response.authResponse) {
// user has auth'd your app and is logged into Facebook
FB.api('/me', function(me){
if (me.name) {
window.open(url);
}
})
} else {
// user has not auth'd your app, or is not logged into Facebook
document.getElementById('auth-loggedout').style.display = 'block';
}
});
// respond to clicks on the login and logout links
document.getElementById('auth-loginlink').addEventListener('click', function(){
FB.login();
});
}
replaced FB.login() with
FB.login(function(response) {
// handle the response
}, {scope : 'user_likes'}); });
I am currently using the following code to get the email id of the user using my app
function get_id(cb){
FB.init({
appId : .......,
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.login(function(response) {
if (response.authResponse) {
var token = response.authResponse.accessToken;
alert(token);
accessToken = token;
FB.api('/me?access_token=' + token + '', function (response) {
cb(response.email);
});
}
},{scope: 'email'});
(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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
}; // ending of get_id()
get_id(function (email) {
userID=email;
alert(email);
});
the current code is in a separate javascript file and this function is called when a button is pressed , I have also included <script src="http://connect.facebook.net/en_US/all.js"></script> in the HTML file . my browser (google chrome) gives me the following error each time I try and access it
"Uncaught ReferenceError: FB is not defined "
I am relatively new to developing Facebook apps , so all the reference I have is the developers page at facebook , I am sure it is a small error but I just cant wrap my head around it , appreciate it if anybody could point out where I could be going wrong
Your code will not load correctly. This part:
(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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
Should not be inside any function, put this in a script tag, after the body opening. It can't be in a separate file. This only does a async-load of all.js, that is the Facebook's JS SDK. If you are using the async-load, you should not put <script src="http://connect.facebook.net/en_US/all.js"></script> in your document, because this will do a sync-load.
This other part of your code:
FB.init({
appId : .......,
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
Also should not be inside the function. This fragment is responsible for starting the FB JS SDK in your page, with your app information, it only have to be called one time for each page, otherwise you will be starting the engine multiple times and it will have a caotic behavior. The "FB" object will only be created after the FB JS SDK loads. You don't know when it's going to happen, because of the async load. So you must assign the FB.init to this window event:
window.fbAsyncInit = function() {
FB.init({
appId : .......,
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
};
You want to create a get_id function that uses the Facebook information. You have to be careful with that. With you are sure that this function will be called after the complete load of FB JS SDK, you can create it in any part of your page. BUT I think the most safe way is to create it inside the window.fbAsyncInit. Don't worry about the token, the SDK does it for you:
window.fbAsyncInit = function() {
FB.init({
appId : .......,
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
function get_id(cb){
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me', function (response) {
cb(response.email);
});
}
},{scope: 'email'});
}
};
But when you do that, you will be not sure if your function was already created or not. So when you call it, you will have to test for it's existence:
if(get_id && typeof get_id == 'function') {
// It's safe to call your function, go ahead
get_id(function (email) {
userID=email;
alert(email);
});
} else {
// Your function does not exists yet, do other stuff
}
Good luck!
You need to put:
(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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
out of get_id function. So it was called before you press the button
PS: you don't need to pass ?access_token= manually - FB JS SDK does that for you
