This is my first time to write JavaScript.... I am using JSBin as the IDE. And I am trying to use JavaScript to allow users login and get their public data in Facebook Graph API.
I created a Facebook Web App, and then created a Test App for this App. None of these 2 Apps work. For each of these Apps, I have created a test user like this:
Below Are How I Failed....
First Try:
I have checked this Facebook Login Doc, changed the app id to my own app id, and version changed to 2.6 as my app settings. But, the problem is, on JSBin, nothing show up.....
Second Try:
Then I found an online example, and I modified the code to make it like this
<html>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '1814637902090044',
cookie : true,
xfbml : true, // parse social plugins on this page
version : 'v2.6' // use graph api version 2.6
});
FB.Event.subscribe('auth.authResponseChange', function(response)
{
if (response.status === 'connected')
{
document.getElementById("message").innerHTML += "<br>Connected to Facebook";
}
else if (response.status === 'not_authorized')
{
document.getElementById("message").innerHTML += "<br>Failed to Connect";
} else
{
document.getElementById("message").innerHTML += "<br>Logged Out";
}
});
};
function Login()
{
FB.login(function(response) {
if (response.authResponse)
{
getUserInfo();
} else
{
console.log('User cancelled login or did not fully authorize.');
}
},{scope: 'email'});
}
function getUserInfo() {
FB.api('/100012237662406', function(response) {
var str = "<b>Email:</b> "+response.email+"<br>";
document.getElementById("status").innerHTML=str;
});
}
// 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>

As you can see, I am using the app id of my Test App, the user is my test user id, but when I click the button, always get this error
Third Try:
Since above error shows "app in development mode....", I have checked these 2 solutions: Solution 1, Solution 2. But I really cannot find those choices in App Review and I cannot find Status & Review. When it comes to Test App, it even has no App Review. Then I tried to public my App like this
But then I got the error:
Here are the url settings:
For that Redirect URL, I have also tried http://localhost/oauthcallback.html, but didn't work either. I don't have any real url can be used for redirect....
I think, if Test App without App Review can be used to test Facebook Login, it may not be the settings in App Review problems.
Do you know how to solve this problem, so that my Javascript will allow user login and send me their public data in Graph API?

i'm having a problem with creating "invite your friends to this page"- button. I'm using static html iframe- application and i'd like to implement a button, which users can click and invite their friends to that same iframe tab. So, how can i implement such a button? i've tried alot of things, but can't seem to get this one work. Thanks in advance for the answers : )
i've tried things like the following:
window.fbAsyncInit = function() {
FB.init({
appId: "YOUR_APP_ID",
status: true,
cookie: true
});
// 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 = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function invite() {
FB.ui({
method: "apprequests",
message: "Check out my great app"
}, inviteCallback);
}
function inviteCallback(response) {
console.log(response);
}
and i've tried to use the page id as app id but it's not working. Is there a way to use url instead of app id?
The error you mentioned in the comments indicates that you did not set up a platform in the App settings. Open the "Settings" tab in your App settings and click on the "Add Platform" button to add a platform (most likely "Website"). Enter the URL of your App in the "Site URL" input field.
What would I need to do to allow asynchronous login/authentication (permissions) between an external site for mobiles and a facebook tab app.
I essentially need one system that does both desktop/mobile.
Example
Case 1 (Mobile/external access) - Logs in using Javascript using login and works fine app works perfectly. - This works the way it's supposed to which is great!
case 2(Facebook user - tab app) - Logs in and gains permissions through PHP SDK onviously the user is already logged in. My problem is javascript knows the user is logged in but still asks the user to login for the permissions they've already given.
TLDR: Why won't Javascript pickup the Auth cookie from the PHP SDK and recognise the user has the correct permissions from PHP? This login flow is fine when the user has logged in via mobile or externally to the app. I've tried them seperately and they work fine just won't work together.
I've seen it working the other way around but I want JS only or PHP>JS NOT JS>PHP.
*Edit
window.fbAsyncInit = function()
{
FB.init({
appId : 'APP_ID_HERE', // App ID
channelUrl : '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
oauth : true // enable OAuth 2.0
});
my event handlers for login/logout and likes goes here.
(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 fblogin()
{
FB.login(function(response)
{
},
{ scope: 'email, user_likes' }
);
}
function createRequestObject() {
var obj;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer")
{
obj = new ActiveXObject("Microsoft.XMLHTTP");
}
else
{
obj = new XMLHttpRequest();
}
return obj;
}
Login for mobile/desktop works great it's picking up the scope but when I use the following code to setup the tab app, the permissions won't transfer to the javascript session.
PHP Code (which works):
<?php
require_once 'src/facebook.php'; // get facebook sdk
$facebook = new Facebook(array(
'appId' => 'APP ID HERE',
'secret' => 'APP SECRET HERE'
));
$user = $facebook->getUser();
$location = "". $facebook->getLoginUrl(array('scope' => 'email, user_likes'));
// check if we have valid user
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$permissions = $facebook->api('/me/permissions', 'get', array('access_token'=>$access_token));
} catch (FacebookApiException $e) {
$fb_user_id = NULL;
// seems we don't have enough permissions
// we use javascript to redirect user instead of header() due to Facebook bug
print '<script language="javascript" type="text/javascript"> top.location.href="' . $location .'"; </script>';
// kill the code so nothing else will happen before user gives us permissions
echo $e->getMessage();
die();
}
} else {
// seems our user hasn't logged in, redirect user to a FB login page
print '<script language="javascript" type="text/javascript"> top.location.href="'. $location .'"; </script>';
// kill the code so nothing else will happen before user gives us permissions
die();
}
// at this point we have an logged in user who has given permissions to our APP
// Facebook opens canvas page (which is the mobile/external page) but doesn't transfer permissions.
PHP works great it transfers the user to the mobile (canvas) page with login/like button. How do I get PHP to pass the perms to my canvas where my mobile/desktop site is?
*EDIT 2:
HTML/PHP:
<div class="container">
<div id="fb-root"></div>
<div id="facebook-div">
<fb:login-button autologoutlink="true" scope="email,user_likes" size="large"></fb:login-button>
<div id="facebook-right" class="fb-like" data-href="https://www.facebook.com/154456204613952" data-width="90" data-layout="button_count" data-show-faces="false" data-send="false"></div>
</div>
//Rest of the code here
Managed to resolve it thanks for your help!
After the PHP instantiated I didn't include the Canvas php file after the user was authenticated... I've been pulling my hair out for months trying to resolve this! This authentication gets passed to Javascript which deals with everything!
This means that both PHP and Javascript calls are able to work within the same application.
The below code is from the official Facebook developer pages, and works in FF and Safari, and sometimes in Chrome — but more often not in Chrome.
On Snow Leopard with the latest Chrome, I click the login button and see a little flicker as the FB login dialog opens and closes. If, in my FB account, I remove and re-add the app, I get asked for permissions, but the auth.authResponseChange event never seems to fire.
Does anyone know if this is a bug, or where I might find a solution that doesn't require me to manually poll the server?
Is this a product of Google+ vs. Facebook?!

Go into chrome settings - advanced settings; Under privacy click "content settings". See if the "Block 3rd party cookies and site data" is checked.
I'm having a similar issue where in chrome the js-sdk will give me the momentary fb popup, but doesnt actually seem to log the user in or recognize the user being logged in/authorized. In my case I think I've narrowed my issue down to that setting.
If you have it enabled, try disabling it to see if that fixes it for you... although that's really just a diagnostic step, it's not a resolution since you would still have users who have that setting enabled.
I'm trying to determine the workaround if any.. possibly involving the use of fb login flow "for web" (ie not using their sdk and thereby potentially avoiding the use of 3rd-party cookies)
here's my post on my version of this issue... can facebook javascript/php SDK's "talk" to each other if 3rd-party cookies are disabled? facebook->getUser() returns 0
Something starange is happening when trying to login to facebook with the javascript SDK on mobile Safari and Android browser. When I clear both my 'history' and my 'cookies and data' and try to login to Facebook using the FB.login method, Safari and Android browser open a new tab with the auth url but stays blank. In all the desktop browsers, everything works just fine.
The strange thing is, is that when I clear my 'history' and my 'cookies and data', then visit facebook.com (not logging in or anything), close the site, open my site and then try to login to FB, it actually works like it should!
So this seems like facebook.com sets a cookie which causes the authentication URL to succesfully load.
I have looked all over for a solution for this problem but couldn't find anything and thus my first stackoverflow post...
Just to be complete, this is the code I use to init the FB SDK:
window.isFacebookSDKLoaded = false;
window.onFacebookSDKLoaded = function () {}; //is injected with a function from another js app on the site
window.fbAsyncInit = function() {
FB.init({
appId : '{{ appID }}', // App ID
channelUrl : '{{ baseUrl }}channel.php', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
window.isFacebookSDKLoaded = true;
window.onFacebookSDKLoaded();
};
(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));
Someplace else in my app I just simply do:
(using google closure)
mm.controller.facebook.DoFBLogin.prototype.doLogin = function ()
{
FB.login( goog.bind( this.loginResult, this ), { scope: app.Config.getFBPermissions() } );
}
mm.controller.facebook.DoFBLogin.prototype.loginResult = function ( result )
{
// logged in
};
If someone has a solution... Thanks in advance!
Having spent hours trawling the web I have found many posts related to this but none seem to work, even some 'working' examples on jsfiddle appear not to work!
I want to register when a user clicks 'like' on my web page.
The 'like' link appears and indeed it pops up a new window for you to log into facebook. But I cannot subscribe to the 'edge.create' event. I know the sdk is loading ok because I can subscribe to the 'xfbml.render' event.
Some posts say that you must have an appId for this to work [I do] but others claim that it works without.
Here is my code:
One point to note is that I am currently running this under //localhost:57477, so I have set the like href to google.com. I did note that one of the posts indentified a recent facebook bug where this event didn't fire if the href domain didn't match that of the web page, but this is now marked as 'fixed'.
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function () {
//console.log('window.fbAsyncInit');
FB.init({
appId: 'myappid',
status: false,
cookie: false,
xfbml: true
});
//Additional initialization code here
FB.Event.subscribe('edge.create',
function (response) {
//console.log('edge.create');
alert('edge.create');
}
);
FB.Event.subscribe('xfbml.render',
function (response) {
//console.log('xfbml.render');
alert('xfbml.render');
}
);
};
// 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 href="http://google.com" class="fb-like" data-send="false" data-width="450" data-show-faces="false" data-font="verdana"></div>
I know this is old thread, but i came here with the same problem.
The thing that worked for me is that Facebook AppID must belong to a domain (set it in Facebook App settings) in which your site stands - localhost won't work then.
Your code looks good to me, I think the problem is in the FB.init() options.
This is what I use:
{
appId: 'myappid',
authResponse: false,
channelUrl: "http://url-to-my-channel-url.com",
cookie: true,
oauth: true,
status: true,
xbfml: true
}
With these init options, I am able to use edge.create to track when someone clicks the Like button.
