I want to create a Facebook login for my website. I used the same code from the Facebook reference. But the login button does displays only as the text "login with Facebook". Can anyone help?
My code is:
<html>
<head>
<title>My Facebook Login Page</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '394261217260358',
status : true,
cookie : true,
xfbml : true,
oauth : true
});
};
(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>
login with facebook
<fb:login-button show-faces="false" perms="publish_stream,email,user_location,offline_access" width="200" max-rows="1">login</fb:login-button>
</body>
</html>
Put this line
<fb:login-button show-faces="false" perms="publish_stream,email,user_location,offline_access" width="200" max-rows="1">login</fb:login-button>
above <script> and below <div id="fb-root"></div> and it should work

I am using the following code for facebook authentication.
<html>
<head>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '498085136....',
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
};
(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));
//LOGIN FUNCTION
function login() {
FB.login(function(response) {
if (response.authResponse) {
alert('Success!');
}else{
alert('Login Failed!');
}
}, {scope: 'email'});
}
</script>
<div onclick="login();">Login with Facebook</div>
</body>
</html>
I dont know what's wrong with that code. When i check my error console, it shows FB is not defined..
Thanks in advance.
Make your html tag like this
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
I'm trying to integrate the facebook registration-login plugin in my site.
Following is an example that is trying just to implement the login button.
According to documentation:
"If the user has not registered for your site, they will be redirected to the URL you specify in the registration-url parameter."
However this doesn't happen. When the user clicks on the login button and he isn't registered in my site yet, the same page, with the login button, reloads.
<?php
<!DOCTYPE html>
<html lang="en-US">
<head>
</head>
<body>
<div id="fb-root"></div>
<script type="text/javascript">
(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/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
window.fbAsyncInit = function() {
FB.init({
appId : 'MY APP ID',
channelUrl : 'MY CHANNEL URL',
status : true,
cookie : true,
oauth : true,
xfbml : true
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
FB.Event.subscribe('auth.logout', function(response) {
window.location.reload();
});
};
</script>
<fb:login-button
registration-url="...my site's address/test.php"
on-login="console.log(arguments)"
/>
</body>
Go to this site: https://www.facebook.com/appcenter/my and remove your app and try again! You will see, it works! ;)
I have added facebook login button for my website. Code is given bellow,
<html>
<head>
<title>My Great Web page</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'MY_APP_ID',
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
};
(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>
<div class="fb-login-button" data-show-faces="false" data-width="200" data-max-rows="1" scope="user_about_me,user_activities,user_birthday,email" on-login="top.location = 'http://localhost/index.php/';">Login with Facebook</div>
</body>
</html>
When the user click 'login with facebook' button, authentication window is displayed with extended permission. When the user allow to access the details, user is directed to index.php file using
on-login="top.location = 'http://localhost/index.php/';"
Now I want to print all access allowed details such as user name,birthday,etc. in the index.php file
Can anyone please tell me how to do that?
I don't know where you got this on-login attribute for the login button (I couldn't find it), but here's an example of how you can do what you want.
It's not tested, I just created this for you to get the point.
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: 'MY_APP_ID',
status: true,
cookie: true,
xfbml: true,
oauth: true,
});
};
FB.Event.subscribe("auth.login", function (response) {
if (response.status == "connected") {
var userid = response.authResponse.userID;
var signedRequest = response.authResponse.signedRequest;
var expiresIn = response.authResponse.expiresIn;
var accessToken = response.authResponse.accessToken;
// do something with the data.
window.location = "index.php";
}
});
(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>
<div class="fb-login-button" data-show-faces="false" data-width="200" data-max-rows="1" scope="user_about_me,user_activities,user_birthday,email">Login with Facebook</div>
You can read more about subscribing to events here: FB.Event.subscribe, and this thread you might find useful: Get user basic information using facebook Login button plugin?
I recently added the Facebook login button to my site and the integration seems to work fine. The only issue I'm having is that the "Login" button is not showing up when I'm logged out of Facebook. Has anyone else had this problem?
I using code straight out of the Javascript SDK docs (https://developers.facebook.com/docs/reference/javascript):
<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
oauth : true, // enable OAuth 2.0
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));
</script>
And have this element on my page:
<div class="fb-login-button" data-show-faces="true" data-width="200" data-max-rows="1">Login with Facebook</div>
Anyone see any issues with what I have here?
Testing this code with a completely trimmed down HTML page worked just fine for me. It showed the login button if you're not logged into Facebook, and shows your friends who are on the site with you if you are. Maybe some other part of your code is interfering? Can you try with the basic HTML as I have below?
<html>
<head>
</head>
<body>
<div id="fb-root"></div>
<script>
var appId = 'YOUR_APP_ID';
var siteRoot = 'YOUR_HOST_NAME';
window.fbAsyncInit = function() {
FB.init({
appId : appId,
channelURL : '//'+siteRoot+'/channel.html', // Channel File
status : true,
cookie : true,
oauth : true,
xfbml : true
});
};
(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>
<div class="fb-login-button" data-show-faces="true" data-width="200" data-max-rows="1">Login w/ Facebook</div>
</body>
</html>
Closely related -- if you want to display something different than the default in the case of the user being logged in, you can check login status with:
FB.getLoginStatus
Or if you wanted to do something after the user logs in you can bind to the login event with:
FB.Event.subscribe('auth.login', function () {
console.log('Hello world!');
});
It's been a while, but I suspect you were seeing this because your app was in "Sandbox" mode. Check your settings.
I'm trying to use facebook connect in my website for the first time.
I've created an app and I copied the code from here AS IS to a blank HTML file
http://developers.facebook.com/docs/guides/web/#login
but all I see is a plain text - "Login with Facebook" - no button, no functionality.
what can be the problem?
The code is -
<html>
<head>
<title>My Facebook Login Page</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'XXXXXXX',
status : true,
cookie : true,
xfbml : true
});
};
(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>
<div class="fb-login-button">Login with Facebook</div>
</body>
</html>
Try adding an XML namespace to the <html> tag of your document.
<html xmlns:fb="http://ogp.me/ns/fb#">
...then try the following for your login button:
<fb:login-button></fb:login-button>
From what I noticed from your HTML code, you lack the tag that links to Facebook's JS SDK.
Add this:
<script src="https://connect.facebook.net/en_US/all.js#appId={YOUR_FACEBOOK_APP_ID}&xfbml=1"></script>
Then instead of doing
<div class="fb-login-button">Login with Facebook</div>
do
<fb:login-button></fb:login-button>
just as what Charley P. answered.
Try to run your application in host. if your project is php based project means run in https://localhost/projectname.
And also check your facebook app setting. your project name should same as site name.
