I am trying to get the Facebook Feed dialog to work at a test site but I keep getting the same error message: "An error occurred with [app_name]. Please try again later.".
When I look at the documentation I realize that the example in the documentation doesn't work either.
Have tried a number of different solutions.
Here is my test code:
<html xmlns:fb="https://www.facebook.com/2008/fbml">
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
// init the FB JS SDK
FB.init({
appId : '400714233333865', // App ID from the App Dashboard
channelUrl : '//demo.xxxxxxx.se/nptest/channel.html', // Channel File for x-domain communication
status : true, // check the login status upon init?
cookie : true, // set sessions cookies to allow your server to access the session?
xfbml : true // parse XFBML tags on this page?
});
// Additional initialization code such as adding Event Listeners goes here
};
function postToFeed(){
FB.ui(
{
method: 'feed',
name: 'The Facebook SDK for Javascript',
caption: 'Bringing Facebook to the desktop and mobile web',
description: (
'A small JavaScript library that allows you to harness ' +
'the power of Facebook, bringing the user\'s identity, ' +
'social graph and distribution power to your site.'
),
link: 'https://developers.facebook.com/docs/reference/javascript/',
picture: 'http://www.fbrell.com/public/f8.jpg'
},
function(response) {
if (response && response.post_id) {
alert('Post was published.');
} else {
alert('Post was not published.');
}
}
);
};
// Load the SDK's source 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));
</script>
<div id='fb-root'></div>
<a onClick="postToFeed('Text');">
Share in the feeeeeeeeeeeeed
</a>
</body>
</html>
Has anyone come across a similar issue or a solution for this?
Make sure that you are testing through same URL as specified in Application settings. In your feed dialog give your own links and images i.e. links of your own domain specified in Application setting and not one given in Facebook example.

I have the following simple code for facebook website login below. I tested the site in a mozilla browser and everything worked fine, opening up a prompt for me to login to facebook, but when I tried again on a windows OS with chrome, my button does not do anything. This is especially frustrating because it looks like the button works - but only sometimes, and I have no idea why. I am hosting my site through google app engine.
I've been trying to figure this out for ages, any help would be greatly appreciated!!
// Additional JS functions here
window.fbAsyncInit = function() {
FB.init({
appId : 'xxx', // App ID
channelUrl : '//http://www.XXX.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
});
};
function doLogin(){
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
login();
} else if (response.status === 'not_authorized') {
login();
} else {
login();
}
});
}
function login() {
FB.login(function(response) {
if (response.authResponse) {
testAPI();
} else {
// cancelled
}
}, {scope: 'email,user_education_history,user_work_history'}); //permissions
}
function testAPI() {
FB.api('/me', function(response) {
alert('Good to see you, ' + response.email + '.');
});
}
// 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));
And my html button:
<button style="position:absolute; margin-top: 4px;margin-left:600px;" onclick="doLogin();">Sign Up With Facebook</button>
EDIT:
When I check the console in my chrome browser where the button doesnt work, I receive the following message:
Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.
Again, the button works perfectly fine when I am running it in my mozilla browser in my linux OS but not on my other computer. I am still not sure what is causing this difference?? Thanks again all for your help.
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 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:
https://gist.github.com/3370553
Or you could replace AuthorizeFacebook with "FB.login" from the JS API
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
For the life of me I cant get Event.subscribe('auth.authResponseChange') to work. See code below
<div id="fb-root">
</div>
<script>
window.fbAsyncInit = function () {
FB.init({
appId: 'XXXXXXXXXXXXXXX', // App ID
channelUrl: 'http://XXXXXXXX.us/', // Channel File
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) {
alert('The status of the session is: ' + response.status);
});
};
// 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));
</script>
<div class="fb-login-button" data-size="xlarge" scope="email" data-show-faces="false"
data-width="400" data-max-rows="1" autologoutlink="true">
Login with Facebook</div>
The login button renders. and i can logout too. only problem is that the auth.response change is not firing and i am not getting the "message" popup
Your code looks fine.
I would access your Facebook app and check on 2 settings in particular.
Check 'Sandbox Mode' -ensure it's set to 'Disabled'
Check your Site URL and/or Canvas URL -ensure they are set to your domain. (i.e. if you are working on this locally your url should look something like http://localhost:#####/ where ##### is your port.
Hope that helps.
Your fbAsyncInit function is called asynchronously so you won't see any alert messages. Try console.log instead for debugging.
