How can I register facebook users on my site ? - facebook

I am trying to find a walk through on how to register users via facebook onto my site.
The facebook developers site keeps confusing me and I was hoping there where easier tutorials to follow.

Stephen,
It can be a little complicated.
You have to combine the documentation at:
http://developers.facebook.com/docs/guides/web/
http://developers.facebook.com/docs/plugins/registration/
Boiling it down to the simplest case:
<html>
<head>
<title>My Facebook Registration Page</title>
</head>
<body>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js">
</script>
<script>
FB.init({
appId:'yourAppID', cookie:true,
status:true, xfbml:true
});
</script>
<fb:registration
fields="[{'name':'name'}, {'name':'email'},
{'name':'favorite_car','description':'What is your favorite car?',
'type':'text'}]" redirect-uri="Your processing URL">
</fb:registration>
</body>
</html>
Facebook will return an encrypted form field with all the user data called "signed Request" You will need to decrypt this field with your secret key. There is an PHP example at the bottom of http://developers.facebook.com/docs/plugins/registration/

Can I avoid 'invite your facebook friends' pop up being blocked on my website?

I have an option to invite facebook friends on my website and I use the code given below. But problem is that it opens in a pop up and chrome and firefox do block the pop up. How can I make it appear in a new tab or window ? Or is there any way so that my pop up won't get blocked ?
<html>
<head>
<title>my website</title>
</head>
<body>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js">
</script>
<script>
FB.init({
appId:'xxxxxxxxxxxxxxx', cookie:true,
status:true, xfbml:true
});
FB.ui({ method: 'apprequests',
message: 'Take a look at this new website.'});
</script>
</body>
</html>
You basically have 2 options;
Open the popup on a mouseclick event (since these are not blocked by the browser), or
Don't use a real popup, but instead use some cool DHTML widget like http://thickbox.net/

Facebook Login pop-up domains, ports, and protocols must match

No matter what I do I get repeated javascript errors in chrome after the facebook-login box pops up.
I am using just the bare minimum login script provided on the FB example site. I've googled this till I'm blue in the face and can't seem to find a solution that actually works for the current version of the Javascript API. Here's my code:
My Facebook Login Page
</head>
<body>
<div id="fb-root"></div>
<script>
FB.init({
appId:'MYAPPID', cookie:true,
status:true, xfbml:true,
channelUrl:'http://www.MYDOMAIN.com/channel.html'
});
</script>
<fb:login-button>Login with Facebook</fb:login-button>
</body>
I of course have MyAPPID and myDomain with the proper info.
Any help/insight would be appreciated as this is driving me nuts and I have quite a few hours into it. Thanks all!

registration-url parameter fails for fb:login-button if oauth 2.0 is enabled

I'm trying to get the registration flow for Facebook login working. Here's a bare-bones example:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title>My Facebook Login Page</title>
</head>
<body>
<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script>
<div id="fb-root"></div>
<script type="text/javascript">
FB.init({
appId:'xxxxxxxxxxx',
cookie:true,
status:true,
xfbml:true,
channelUrl : 'http://<myWebSite>/channel.html',
oauth:true
});
</script>
<fb:login-button registration-url="http://<myWebSite>/register"/>
</body>
</html>
(The only things I've replaced above are the website and the appID)
If I try it like this, the login button shows up, but clicking it causes FireBug to report 'Unknown status: undefined' in the browser log. If I remove the 'oauth=true' line though, it works. I'm trying to adhere to the new oauth 2.0 standard, so I'd like to leave it in. Has anyone else run into this? Seems like if this was a bug, it would have been caught pretty early on.
the 'registration-url' parameter is no longer supported by , take a look in the documentation of it. http://developers.facebook.com/docs/reference/plugins/login/
Just check if the user is logged in via the JS-SDK

Can I use Facebook's fb:friend-selector in an iframe?

I'm trying to use Facebook's fb:friend-selector FBML tag, but my application is running in an iframe. Is it possible to use this tag in an iframe? If so does anyone have any examples?
Yes, this is definitely possible, but you have to use Facebook Connect and XFBML. Specifically, you want to use the fb:serverfbml tag to get fb:friend-selector working. I have an iframe app whereby I use all of this and the fb:friend-selector in the standard "invite friends to your app" context, and it works great.
Here is the body of my template file, which gets output inside the body of my iframe:
<fb:serverfbml style="width: 650px;">
<script type="text/fbml">
<fb:fbml>
<fb:request-form
action="http://example.com/invite/sent"
method="POST"
invite="true"
type="My App"
content="Try out my app!
<fb:req-choice url='http://your-facebook-canvas-url'
label='<?php echo htmlspecialchars("Accept button text",ENT_QUOTES); ?>'
/>
" >
<fb:multi-friend-selector
showborder="false"
actiontext="Invite your friends to try My App."
exclude_ids="<?php echo $excludeIds; ?>"
rows="3"
/>
</fb:request-form>
</fb:fbml>
</script>
</fb:serverfbml>
In the footer of the page, I have the standard Facebook Connect code, which will load and render the fb:serverfbml contents:
<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script>
<script type="text/javascript">
FB_RequireFeatures(
["CanvasUtil"],
function(){
FB.XdComm.Server.init('/xd_receiver.html');
FB.CanvasClient.startTimerToSizeToContent();
}
);
</script>
<script type="text/javascript">
FB_RequireFeatures(["XFBML"], function(){ FB.Facebook.init("Your Facebook API Key", "/xd_receiver.html"); });
</script>
That should be all you need (fill in your own options where applicable, of course). You'll have to set up Facebook Connect to work with a cross-domain receiver file. I suggest following the rendering XFBML steps.
The question in this thread is still relevant but the answer is out of date. You should use the new javascript SDK. This should replace the second code snippet posted by zombat
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script type="text/javascript">
FB.init({appId: 'your app id',
status: true,
cookie: true,
xfbml: true});
FB.Event.subscribe('auth.sessionChange', function(response) {
if (response.session) {
// A user has logged in, and a new cookie has been saved
} else {
// The user has logged out
}
});
</script>

Since that are a lot of questions about the friend-selector within an iframe.
Guys the correct sintax now is <fb:serverfbml width="650px">
one MAJOR and IMPORTANT point that gets missed is that many of you (including me) stick in scripts just about anywhere... but the "FB" load.js file needs to be loaded IMMEDIATELY after the body tag.
at least this is what I found to make everything work and humm accordingly. I found it on a post on some other site (wasn't sure if I should post it here or not...) but it came after spending countless hours, doing the above aforementioned - as well as following every other 1,2, 3 step punch into getting the iframe to size properly...
and now i've gotten it to work :)
