Is there an API for opening a popup containing the same status update functionality as in the Facebook Wall?
I basically want to open the following UI in a popup...
How can I do that?
You have to mention the onclick function else what suits your need. oauth2 in facebook involves two steps, call authorize to get code, then call access_token to get token. One way to deal with the pop login:
open login url in new window just like you did,when the facebook redirects back to your url in the popup, you set the cookie either through server side code or using javascript to capture url query parameter, when page is loaded in the popup, close the window immediately window.close.
On your main page, after your window.open code, add JavaScript code to detect if popup is closed and capture the cookie:
var signinWin;
`$('#FacebookBtn').click(function () {
var pos = screenCenterPos(800, 500);
signinWin = window.open("[URL]", "SignIn", "width=780,height=410,toolbar=0,scrollbars=0,status=0,resizable=0,location=0,menuBar=0,left=" + pos.x + ",top=" + pos.y);
setTimeout(CheckLoginStatus, 2000);
signinWin.focus();
return false;
});
function CheckLoginStatus() {
if (signinWin.closed) {
$('#UserInfo').text($.cookie("some_cookie");
}
else setTimeout(CheckLoginStatus, 1000);
}`
hope it help you.
The facebook UI responsible to post a feed is described here.
If you want to have the same design in your application you have to design it yourself, which would be easy with jQuery + ajax

I need to record to the database if a user likes an iframe page tab using the official Facebook 'like' button at the top. I did a search here at stackoverflow and found a javascript snippet ...
FB.Event.subscribe('edge.create',
function(response) {
alert('You liked the URL: ' + response);
}
);
But it doesn't fire for the official button (only like buttons added to the page)? I declare it after FB.init and before FB.Canvas resize inside the asynchronous call. Is there a way in PHP to capture this - possible on refresh? Either JS or PHP is okay (since JS can simply ajax a php file). The signed request contains whether they like the page or not but I need to capture it as it happens (or just happened).
Any help greatly appreciated :-)
Try :
window.fbAsyncInit = function () {
FB.Event.subscribe('edge.create', function (targetUrl) {
_gaq.push(['_trackSocial', 'facebook', 'like', targetUrl]);
});
};
I think you just need to setup the subscript inside the fbAsyncInit.
Did it a purely PHP way in the end.
1: Get the signed request from facebook and extract the liked stats
2: Create a variable $liked and set to "yes" or "no" based on signed request value
3: Manipulate a session - use a session because the page gets refreshed when you "like" but the session remains (but the request value will have changed)
if(isset($_SESSION['likestatus'])){
if($_SESSION['likestatus'] == "no" && $liked == "yes"){
// do mysql updatestuff cause has liked page since session started
$_SESSION['likestatus'] = $liked;
}
else{
$_SESSION['likestatus'] = $liked;
}
}
else {
$_SESSION['likestatus'] = $liked;
}
I have read a number of questions and answers, including this one on StackOverflow and none works. My question to all responses I have seen are 'does it work in Safari?'.
I am trying to get this to work with Safari. It works on Chrome and Firefox fine. But in Safari the login screen just freezes and I get the "Unsafe JavaScript attempt to access frame with URL" log message.
I have a canvas app. I want to log the user in and redirect them to a page once they have logged in. I am trying to redirect directly after login. I have tried
setting window.top.location to a facebook url (with some data passed to a signed request as the all_data argument)
setting window.location to a URL with the same domain as my app.
subscribing to the auth.login event and putting the redirect there
putting the redirect in the callback to login
None of these works for Safari. I'm starting to think that there's no way to do it.
function doSomething()
{
FB.login(
function(loginResponse)
{
if (loginResponse.authResponse)
{
window.top.location = "my url"
}
},
{
scope:"some,scope"
}
);
}
}
In response to Nitzan Tomer, here is the equivalent code which doesn't work with Safari but does work with others:
function myThing()
{
FB.login(function(loginResponse)
{
if (loginResponse.authResponse)
{
FB.api('/me', function(response)
{
window.location = "http://my_app.com?x=" + response.xyz;
});
}
},
{
scope:"scopes"
}
);
}
This is not much of a solution to your problem, but more of a "workaround", though it still uses window.top.location but not from a callback so maybe it will work (I'm just not sure where the callback is executed, since it's the fb sdk that executes it, maybe they call it from the fb iframe inside your iframe).
Instead of using client side authentication, you can use the server side flow.
The entire process is happening on the top window, since it starts by you redirecting the user to the oauth dialog using window.top.location.
When the process ends facebook redirects the user to your redirect_uri, and there you can simply redirect the user where ever you want.
I hope this will help.
Also, you should be aware that in the Facebook Platform Policies it states:
13 . The primary purpose of your Canvas or Page Tab app on Facebook must not be to simply redirect users out of the Facebook experience
and onto an external site.
It turns out the problem was occurring slightly earlier in the login process and the callback never got called. I did set a breakpoint in the callback (which wasn't called) but I thought the breakpoint might not work for some reason (perhaps because it was being executed in the context of another window).
Anyway, the problem was that the channel file (which the docs seem to suggest are optional) wasn't working properly, and this caused a problem with Safari but not with other browsers.
I'm using the following code to subscribe to fb login and logout events.
FB.Event.subscribe('auth.logout', function(response) {
RefreshPageOnFBStatusChange(response);
});
FB.Event.subscribe('auth.login', function(response) {
RefreshPageOnFBStatusChange(response);
});
function RefreshPageOnFBStatusChange(response)
{
alert(response.status);
}
I want to redirect users to different pages when they are logged in or logged out. The function I'm using here gets called only during the actual page load, and never after that. I have a fb-like, fb-share and live stream plugin on a page. When I login and logout of live stream, nothing happens. Help!
Please modify your question and provide all FB-related code.
This may answer you question:
Facebook FB.Event.subscribe event does not fire:(
For User Status you can use if(FB._userStatus == "connected"){} to check user is login or not And for Logout & login you can use following simple code
FB.logout(function(response) { window.location = redriect_uri;
});
It seems like these events don't fire when you use the live chat plugin because it has its own way of handling the login and logout. What I had to do to solve this problem was to set a timeout of 5 seconds and call a javascript function that did a FB.GetLoginStatus, and based on what it was I would refresh the page. Not the best way of doing it, but I was left with no choice.
For some time now I try to figure out how these guys were able to add "Sign online here" button which is "install App" button on their fan-page tab:
http://www.facebook.com/GuinnessIreland?v=app_165491161181
I've read around the web and couldn't come up with any solid solution. The FBML and FBJS documentation left me with nothing.
So please, if anyone can help me with this.
NOTE: To make multiple tests on the Ajax request that are sent, do not accept the App install. It behaves differently after that.
I had some problems with finding out about it as well. There is no info about this kind of behavior in wiki or anywhere. I got it working after trying some possible solutions and the simplest one is to make user interact with content embedded in fan page tab such as click on something etc. Then you need to post an ajax request with requirelogin parameter to pop up to come out. The simple example would be:
user_ajax = function() {
var ajax = new Ajax();
ajax.responseType = Ajax.RAW;
ajax.requireLogin = true;
ajax.ondone = function(data) {
new Dialog(Dialog.DIALOG_POP).showMessage('Status', data, button_confirm = 'Okay');
}
var url = "http://yourappurl.com/request_handler"
ajax.post(url);
}
And the trigger for it:
Interaction
Then if user is known to be using your application (fan page tab) you can prompt him for additional permission like publish stream or email communication by calling:
Facebook.showPermissionDialog('publish_stream,email');
Hope this solves the problem.
I have a Facebook app that is built as an iFrame. I am using the JavaScript client API loaded via:
http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php
In my initialization code, I use the requireLogin method to ensure that the user has authorized the app. I have found this to be necessary to be able to gather the user's name, avatar, etc. for the scoreboard. Here's a representative code snippet:
FB_RequireFeatures(["Connect","Api"], function() {
FB.Facebook.init("...API_KEY_HERE...", "xd_receiver.htm");
var api = FB.Facebook.apiClient;
api.requireLogin(function() {
api.users_getInfo(
FB.Connect.get_loggedInUser(),
["name", "pic_square", "profile_url"],
function(users, ex) {
/* use the data here */
});
});
});
This causes the iframe to redirect causing the Facebook authorization screen to load within my app's iFrame. This looks junky and is somewhat confusing to the user, e.g. there are two Facebook bars, etc.
Question 1: is there anything I can do to clean this up while still implementing as an iFrame, and still using the JavaScript APIs?
According to the FB API documentation:
FB.ApiClient.requireLogin
This method is deprecated - use
FB.Connect.requireSession instead.
My experience though when I replace api.requireLogin with FB.Connect.requireSession it never gets invoked. I'd prefer the recommended way of doing it but I struggled and was not able to find a way to get it to work. I tried adding various arguments for the other two parameters as well with seemingly no effect. My expectation is that this method will load in a dialog box inside my app iFrame with a similar authorization message.
Question 2: what am I missing with getting FB.Connect.requireSession to properly prompt the user for authorization?
Finally, at the end of the game, the app prompts the user for the ability to publish their score to their stream via FB.Connect.streamPublish. Which leads me to...
Question 3: am I loading the correct features? Do I need both "Api" and "Connect"? Am I missing any others?
Here is a summary of the changes I needed to make to clean up the authorization process. It appears that iFrames must fully redirect to properly authorize. I tried using the FBConnect authorization but it was a strange experience of popup windows and FBConnect buttons.
Ultimately this game me the expected experience that I've seen with other FB apps:
FB_RequireFeatures(["Connect","Api"], function() {
var apiKey = "...",
canvasUrl = "http://apps.facebook.com/...";
function authRedirect() {
// need to break out of iFrame
window.top.location.href = "http://www.facebook.com/login.php?v=1.0&api_key="+encodeURIComponent(apiKey)+"&next="+encodeURIComponent(canvasUrl)+"&canvas=";
}
FB.Facebook.init(apiKey, "xd_receiver.htm");
FB.ensureInit(function() {
FB.Connect.ifUserConnected(
function() {
var uid = FB.Connect.get_loggedInUser();
if (!uid) {
authRedirect();
return;
}
FB.Facebook.apiClient.users_getInfo(
uid,
["name", "pic_square", "profile_url"],
function(users, ex) {
/* user the data here */
});
},
authRedirect);
});
For iFrames, the solution was ultimately to redirect to the login URL which becomes the authorization URL if they are not already logged in.
I think that FB.requireSession only works from a FB connect site outside of
Facebook. If you're using an app hosted on apps.facebook.com use the php api
call instead,
$facebook = new Facebook($appapikey, $appsecret);
$facebook->require_login();
or link to the login page.
Of these methods to login
* Using the PHP client library
* Directing users to login.php
* Including the requirelogin attribute in a link or form
* Using FBML
only the first 2 are available to iframe apps hosted on apps.facebook.com
I think requirelogin and fbml only work with fbml canvas apps.

Question 1: is there anything I can do
to clean this up while still
implementing as an iFrame, and still
using the JavaScript APIs?
Question 2: what am I missing with
getting FB.Connect.requireSession to
properly prompt the user for
authorization?
Please have a look at this. This article discusses correct use of require session and provides links on how to implement that. And yes, you are right, the requireLogin has been deprecated and won't help any more.
Question 3: am I loading the correct
features? Do I need both "Api" and
"Connect"? Am I missing any others?
As far as I know, you can use both API and Connect together, basically you access Facebook's API with the help of JavaScript.
For iframe apps however, there is no great help and minimum support of API with some handful functionality available. See this for more info.
This causes the iframe to redirect
causing the Facebook authorization
screen to load within my app's iFrame.
This looks junky and is somewhat
confusing to the user, e.g. there are
two Facebook bars, etc.
Finally and personally I have not seen any iframe app requiring user to add the app first. This will create the problem of two bars you mentioned as quoted above.
The link I posted at the beginning of my answer has some useful links to get you started and decide the next-steps or possibly making changes to your apps.
