In stead of website build-in login form, I use Facebook login to get user authentication, then they can browse all other page on my website.
My question is how to store user permission so that in all page, my website recognize that the current user is a authenticated user?
Is there any function in Facebook SDK provided these feature or I should use basic PHP function?
Thanks
The SDK itself doesnt offer you such a method to store the data. You have to do this by your own. There is own programmed component that can manage such for you. It stores the access_token for the users in a database. This can directly done via ajax. You can request for users permissions and store the data in the database...in one step!

I am integrating facebook login to my website. I want to store information of users who logins with facebook. After login another page should be loaded. How to call a function when user logins to the website?
While this will obviously depend on how you are actually logging in to facebook in the first place (using the PHP SDK, Javascript or whatever), if you are doing it correctly, you will be specifying a URL to go to upon successful login. All you need do is add a parameter to that url, and you will be able to detect that you logged in via facebook.
So your URL might be something like:
http://www.mysite.com/loginsuccess.php?source=fb
If you want further help can you outline how you are actually running the login process?
I am using the Graph API for Facebook on my iPhone application. The problem is, I don't want the user to have to re enter their email address each time they want to login to integrate Facebook with my app. Is there a way to save and auto fill the login information using the Graph API?
Using the Graph API, there is no need for you to store the credentials, more than that, you should NOT store the credentials. As explained in the API dedicated help page the authentication process is handled by a secure token.
Meaning that if the user is already authenticated on Facebook using another application, it might be ( based on authentication process used ) already authenticated within your app.
You might check the token validity by using the isSessionValid method from the Facebook class.
Have a look to the iOS Facebook SSO link, it explains everything you need.
I want to allow users connect to my website using their facebook account.
First, the user authorizes my application and then I get an access token. Problem is, that I'm supposed on the first time to register the user, and the next time to auto login him based on his facebook email.
How do I create a SECURE way to auto login the user?
I'm using pure javascript, but I can't find any way to create a secure mechanism.
Thanks.
Facebook should handle all that for you - when they come back to your website, they can click the 'login' button(javascript SDK) and facebook should pass you back an access token.
I may, however, have misunderstood the question.
I am trying to understand, how facebook authentication works and how the flow should look like. I am working with Google App Engine and I have managed to obtain first the code and then access token. Using it I can for example retrieve user's friends list. This is all cool.
However, how can I store this access_token? I wan to allow my user to access different pages in my facebook app and I will need this access token on those pages. How can I store it and how can I retrieve it? Or maybe no matter which page user accesses I first need to get the code and then access token and only then can I perform some operations on his behalf?
I don't want to use javascript sdk for now. Is it possible to do it all from server side?

just store the access_token in the datastore.

It is from the facebook python sdk.

If you don't want to use javascript sdk, you need to see this document. It has all details for facebook Oauth.
http://developers.facebook.com/docs/authentication/
While facebook redirect your user to your page assigned by redirect_uri. It will give your the code (A_CODE_GENERATED_BY_SERVER), then your server can get the user's access_token/facebook id with server side facebook api + code. Then you can login your user (set the session/cookie) and do whatever you want.
How do they manage to get user to login to Twitter / Facebook through Javascript so smoothly?
I am trying to replicate it for the web app. Basically, the user only needs to add a javascript snippet to their site to kickstart but I am clueless as to how to integrate facebook and twitter connect seamlessly.
Do they store access tokens after successfully authenticating a user?
Short answer is yes, they store access tokens after successfully authenticating a user.
After you try facebook and twitter apis, you'll see that, they both returns ids for every user who succesfully logged-in through your application. You can then simply add those ids pairing with the platform they logged in to your database. You can then use that data to track users easily.
You need to
Create applications on both platforms
Have pages for each provider to check if user performed a succesful login
Check if user is a newcomer and add that user to your database if so.
Set a session or cookie variable of user's local id in your own application or do whatever you are normally doing to track if a user logged-in as that user is your local user.
