I have added a login button to my site anad added scope to publish actions as per guide i found here: developers.facebook.com/docs/reference/plugins/login/ and this works fine but my question is: How can i have same function but this prompt to show to users without needing to click on the Login Button.
If user has not installed app, he would be prompted automatically to install it.
Thanks for any help.
Use FB.getLoginStatus of the JavaScript SDK to see if you have a user connected to your app visiting your page. If not, redirect them to the server-side auth dialog (using client-side auth would not be a good idea, since most browsers will block a popup that’s opened without any actual user interaction).

I am developing a site to manage Facebook Feeds and is using facebook-php-sdk-v4-4.0-dev.I have the user Login and access token saved to database functionality working properly.
I need to show Switch Facebook User account Option, If he is already logged into facebook account. Currently if he is logged into facebook account on another tab. There will not be facebook authentication, It just shows App Permissions window and then completes facebook login process.
But I found that this option is available in Facebook Login for the Web with the JavaScript SDK example...A pop up come up for Login and you can switch user on top right side.
Please let me know how to accomplish this in PHP sdk 4 or work around, or am I missing something here.
Thanks in advance....
Please see this screenshot

I have added a screenshot where JavaScript SDK show switch user button (top right side)when user is logged in to facebook account in another browser tab.(this comes up as pop up)
But there is no such option when using php sdk. instead of pop up, its come as a webpage and it does not have switch user account.
I want to integrate facebook api to help in the registration process in my website. It was working fine before - the standard fb login button appears, the pop-up window to login to fb was working, some of the user data are obtained. However after several trials with me modifying the code as the feature isnt fully integrated yet in my site, whenever I press the login button what replaces the fb login page is "This webpage is not available." I already retracted the modifications I made to the point that it was back to the version wherein it was working before. I also created another app and replaced the app id and secret key, still it displays the same message. I do not know what is wrong. Please help.
Update:
I uploaded the project files to another hosting site and it works! Could it be that the previous domain is now blocked?
Please read the other posts, dude... we're all waiting for the FB to fix the issue...
I'm building a public installation using an iPad, built as an iOS web app (using the "Add to Home Screen" functionality) which is going to allow users to share content on Facebook.
I'm currently logging the user in to Facebook and getting them to authorize my Facebook app when they click my custom share button. On a successful login, I open Facebook's Feed dialog and allow them to share. Once they have shared (or clicked cancel) I automatically log them out, making sure that the next user that uses the public installation won't be able to share to the previous user's Facebook account.
This all works well, but things get tricky if someone was to hit my custom share button, log in to Facebook and then not allow my app. This would mean that they have logged in, but as they haven't authorized the app, I don't have an access token, and so can't log them out (FB.logout() requires an access token).
Is there a way around this?
Or is there another way that I can log a user out?
Or is there a safe way to allow a user of a public installation (built in HTML) to share on Facebook and be automatically logged out afterwards? Would building a native obj-c app, and using Facebook's iOS SDK help?
The best I can think of is that if the user logs in but doesn't allow the application, they are told that they need to log out, and redirected to Facebook to be able to do this. However this offers them the chance to browse Facebook and (through shared links in their feed) the whole Internet - this isn't acceptable for our installation.
I solved this problem by creating a native iOS app, where the Facebook share link opened in it's own UIWebView. And once the sharing was complete, I deleted all session & cookie information, effectively logging the user out.
Today, on my Facebook app, links appear to be broken. Everytime you click a link (to another page of the application, not external), Facebook returns the user to the login prompt, even if the user has already logged in.. I usually use relative urls, but if I set absolute, the link doesn't work too, but in this case the page doesn't change...
Anyone having same problems? Any ideas? I just can't find solutions..
Edit: for "Facebook app" I mean an iframe application that runs on Facebook site, not the Facebook application for a mobile device
Solved :) The problem was I used on old versione of the PHP SDK. I've updated the SDK with the latest version and also the Login part of the code; now it's ok. Thanks all for your help ;)
Did you tried to reinstall the Facebook app? Also if you use Android you can delete the cache on your phone.
Everytime you click a link (to another page of the application, not external), Facebook returns the user to the login prompt, even if the user has already logged in..
Do you have Authenticated Referrals turned on for your app?
Otherwise, you must be triggering login yourself somewhere in your app. If so, check the conditions under which you are doing so, and if your app recognizes a logged in user correctly, or if maybe there is some kind of cookie problem.
If that doesn’t help you to figure it out on your own, please update your question with relevant code.
I have installed the facebook API in phonegap but i have hard time making it work see link .The index.html file in the exemple folder has a login button that once taped opens the native facebook application on my device requiring email and password. After having authenticated me, it takes me back succesfully to my app.
Whenever i tap on the "getsession" button for exemple it shows me an alert saying "undefined". I want to know how to get the access token that is given right after the authentication process within my app and everything related to the session so i can perform other tasks?
Thank you
