I am new to Facebook app development. Following is my html and script code to retreive access token for facebook users.
I am having a checkbox and on Selecting the checkbox, I need the facebook login authentication form to be loaded.
<html xmlns:fb="https://www.facebook.com/2008/fbml">
<body>
<table>
<tr>
<td>
<input type="checkbox" value="Facebook" name="facebook" id="facebook" onclick="checkFacebookLoginCredentials(this,'fb')"/>
<div id="fb-root"></div>
</td>
</tr>
</table>
</body>
<script type="text/javascript">
var userFBAccessToken="";
function checkFacebookLoginCredentials(field, accountType)
{
loadFBAuthenticationWindow(); //Function to load the facebook login authentication window
}
function loadFBAuthenticationWindow()
{
window.fbAsyncInit = function()
{
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
});
FB.login(function(response)
{
if (response.authResponse)
{
console.log('Welcome! Fetching your Facebook information....');
userFBAccessToken = response.authResponse.accessToken;
console.log('userFBAccessToken: ' + userFBAccessToken);
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: 'user_activities,user_notes,user_photos,user_videos,user_status,offline_access'});
};
// Load the SDK Asynchronously
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol
+ '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
}
</script>
</html>
When I try to load the above html, I can see the iFrame (Facebook login authentication form) loaded properly in Chrome and FireFox browsers.
But when I tried to execute in SAFARI, the iFrame is not loaded.
Can anyone please say, what I have missed in the above code? Any suggestion please..
This sounds like a bug, especially if this is working in one browser but not the other. Please file this in the bugtracker: http://developers.facebook.com/bugs

I googled for nearly 4 hours and am posting this.
I am trying to implement facebook login in my website.
The problem is login is working fine, after login it has to redirect to anther custom page,
its not redirecting but staying in the same page. Here is my code that am using.
<head>
<title>My Facebook Login Page</title>
<script src="//connect.facebook.net/en_US/all.js"></script>
</head>
<body>
<div id="fb-root"></div>
<fb:login-button perms="email"></fb:login-button>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'XXXXXXXXXX',
status : true,
cookie : true,
xfbml : true
});
FB.Event.subscribe('auth.login', function() {
window.location = "about_us.html";
});
};
(function() {
var e = document.createElement('script');
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);
}());
</script>
<!-- <div class="fb-login-button" >Login with Facebook</div> -->
Kindly guide me where am wrong also if possible correct code
I had taken the code from below link.
Redirect after clicking on the Facebook login button, even if already logged in Facebook
Thanks in advance.
you can just add this somewhere
FB.login(function(response) {
if (response.authResponse) {
window.top.location = "http://www.foo.com";
}
});
When I put
window.top.location = "http://www.foo.com";
under
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
window.top.location = "";
});
it worked.
We just switched to new PHP SDK and JS today. but the problem is weird. When we dont use show-faces with perms attribute it doesnt show popup. Only way to get permission popup appear, we need to use show-faces attr.
is this a bug ?
<fb:login-button perms="email, publish_stream, offline_access, create_event, user_photos, user_online_presence, user_videos, user_website, user_events, user_relationships, user_interests" size="large">Sign Up With Facebook</fb:login-button>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '<?php echo $facebook->getAppID() ?>',
cookie: true,
xfbml: true,
oauth: true
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
FB.Event.subscribe('auth.logout', function(response) {
window.location.reload();
});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
Thanks
EDIT:
OMG. i just found the solution, with the new JS SDK we must use scope instead of perms attribute!

Alternatively you can use straight Javascript and make your own buttons.
<script>
function addPermissions(permissions){
FB.login(function(response) {
if (response.session) {
if (response.perms) {
// user is logged in and granted some permissions.
} else {
// user is logged in, but did not grant any permissions
}
} else {
// user is not logged in
}
}, {perms:permissions});
}
</script>
<a onclick="addPermissions("email, publish_stream,...");">Click me</a>
The user is logged in to my site using the latest PHP SDK.
If the user clicks the facebook logout URL that appears in my site, he logs out from facebook and is redirected back to my site where I can do some cleanups.
However, if while in session (in my site and in facebook) the user goes to www.facebook.com and logs out from there, my site is clueless about it. I need to be notified about this in my site so I can do cleanups.
The only solution I can think of is to call from every page in my site to getLoginStatusUrl(), but this seems to be an overkill. Isn't there a way to ask facebook to call some URL in my site when the user logs out from facebook itself?
You can use js to subscribe to the auth.logout event as per the facebook example:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '<?php echo $facebook->getAppID() ?>',
cookie: true,
xfbml: true,
oauth: true
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
FB.Event.subscribe('auth.logout', function(response) {
window.location.reload();
});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({appId: '197724456937488', status: true, cookie: true, xfbml: true});
// this will fire when any of the like widgets are "liked" by the user
FB.Event.subscribe('edge.create', function(response) {
document.getElementById('likepost').style.display = "";
document.getElementById('falsebox').style.display = "none";
document.getElementById('fb').style.display = "";
});
FB.Event.subscribe('edge.remove', function(response) {
console.log('This was UNliked from this page: ' + window.location);
});
};
(function() {
var e = document.createElement('script');
e.type = 'text/javascript';
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);
}());
</script>
<div id="fb" style="display:none">
<fb:like-box href="<?php echo $detail['Post_FB'] ;?>" width="292" height="100" show_faces="false" stream="false" header="false"></fb:like-box>
</div>
<div id="link" style="display:none">
<fb:like href="http://design-pro.co.cc/appleworld/post.php?id=<?php echo $id?>" send="false" width="450" show_faces="true" font=""></fb:like>
</div>
Use this as your starting point for reference: http://developers.facebook.com/docs/reference/javascript/FB.init/
First thing to notice is how FB.init() call is wrapped in:
window.fbAsyncInit = function() {
...
};
You are already setting 'status' to true in your init call, so you should be able to subscribe to an event which will return the status value, which tells you the user's login status.
Check out: http://developers.facebook.com/docs/reference/javascript/FB.Event.subscribe/
Your FB.Event.subscribe(...) call should also be inside the same window.fbAsyncInit() call.
Once you verify that user is logged in, you can check for fan status. You still have to use the old REST API, since Facebook hasn't ported this over to Graph API: http://developers.facebook.com/docs/reference/rest/pages.isFan/
Please note: We are in the process of
deprecating the REST API, and will be
adding equivalent support to the Graph
API for this method. You should
continue to use this method until we
announce support in the Graph API.
Hope this points you in the right direction.

I am trying to have a connect button on my site. Once the user has clicked the facebook login button, the pop up will ask the user to enter the authentication detail and the parent window will either redirect or refresh the page and the login button became a logout button.
My problem is when a user clicked the connect button from the popup, the popup page will redirect to my canvas page rather than closed the popup instead.
Many people have posted this issue, if you have done everything else right, the reason for this is xd_receiver file was not read by the fb.
You need to make sure that where your fb connect button is, you specify the correct path to xd_receiver.html file somewhere on bottom of that page. Something like below:
<script type="text/javascript">
FB.init("your api key here", "xd_receiver.htm");
</script>
It is even better and easier to put the xd_receiver file on your site's root folder and specify it with full domain url like this:
<script type="text/javascript">
FB.init("your api key here", "http://www.yoursite.com/xd_receiver.htm");
</script>
Here's a sample of facebook connect, login and logout, works very well,
Also make sure you add your site url under your app settings -> Website - > Site URL:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>Facebook Connect Sample</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'YOUR APP ID',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
/* All the events registered */
FB.Event.subscribe('auth.login', function(response) {
// do something on login
login();
});
FB.Event.subscribe('auth.logout', function(response) {
// do something on logout
logout();
});
FB.getLoginStatus(function(response) {
if (response.session) {
// logged in and connected user, someone you know
login();
}
});
};
