I'm linking my app to Facebook, and would like people to log in with their Facebook account, but I can't figure out how to do this. I had read up on Facebook Connect, but it seems that that's not used any more - but every tutorial I can find seems to refer to it. When I try to follow them, it doesn't work, because the interface has changed.
So, can anyone direct me to a tutorial or guide to doing this the new way?
Basically, what I want to do is this:
A user who is signed into Facebook and comes to my webpage is automatically logged in to my app (with the usual Facebook 'granting permission' windows etc), or can sign in with their Facebook account if they're not already logged in.
I then want to use Facebook to link users with their friends who are also registered on my site, so they can share things.
I would also like to have access to Facebook comments made on wall posts from my site - so the comment stream for a particular post can be seen on my site as well as on Facebook, and comments can be made on either.
If anyone can point me in the right direction (or even tell me what I should be typing in to Google!) I'd be very grateful.
Thanks.
Some sample apps that do many of the things you speak of are shown here. The Graph API is probably your best bet right now for delivering the content and access you need and there are numerous tutorials online for how to use it, including the Facebook Developers site itself.
You will find good Tuts on ThinkDiff, e.g.
http://thinkdiff.net/facebook/new-javascript-sdk-oauth-2-0-based-fbconnect-tutorial/
http://thinkdiff.net/facebook/php-sdk-3-0-graph-api-base-facebook-connect-tutorial/
http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development-php-sdk-3-0/
I know this is an older question, but the current method for authentication is OAuth 2.0.
Facebook provides a pretty good outline of what steps are necessary in this Reference:
https://developers.facebook.com/docs/authentication/client-side/
This example allows the authentication to occur entirely in Javascript on the client side so that you can request a potential user to authenticate via Facebook and then confirm access to your application.
If the user is already logged in, only the access confirmation for your application is performed.
If the user is already logged in and access has already been granted, the user is not required to login, or reconfirm access.

Facebook removed the /{user}/home api on October 6, 2015.
I'm wondering if anyone knows if there are any alternative methods to access news feed data.
I've worked with /{user}/feed but of course that only shows data for the currently logged in user.
I've tested with my wife to be sure and she can only she posts on her wall and I can only see posts on my wall and neither of us can see each others posts no matter what permissions are set on them.
I'd like to think that currently logged in user could access any data via the api that they could via the site (assuming they've granted the proper permissions of course.), but this doesn't appear to be the case.
Of course I am particularly interested in the news feed and I suspect that the there is no alternative but I don't want to give up yet.

No, that would be a privacy issue, because your app could access data/posts of users who did not even authorize your app and no one knows what you do with the data. So the answer is no, there is no alternative.
I just created last week an App and I've read that offline access doesn't work with newly created apps.(I haven't found any tutorial on the web. I am really new to facebook apps)
with this new change in facebook, I don't know how to use the current thing.
I badly need this feature because I don't want the user keeps logging-in in facebook everytime he visits and posts a status in my site as well in his facebook wall. I just want the user to be stayed connected and be able to post on his wall automatically thru my site once he authorized my app.
Thank you.
There are very clear and simple instructions on the following documentation to explain what you need to do to switch to long-life access tokens:
https://developers.facebook.com/roadmap/offline-access-removal/
Also, from your description, it sounds like you are spamming and breaking Facebook Platform Policies. Users will hate any app that automatically posts on their behalf, so I recommend you do not do that, as either people will stop using your app or they'll report it and it'll get banned.
I'd like to know if there is a possibility to check (using Graph API or any other way) whether given user likes / shares a specific link. Probably I'll have this user's facebook ID or facebook login, but my site is non-Facebook application. Actually it's Dot Net Nuke portal (target: .NET with MS SQL Server) with part of it being avaliable as Facebook app, but certainly not greater part of it, so the solution should be out of Facebook Connect, although it's not a showstopper if it's necessary.
We'll be giving points to users who share/like most of links that we serve in our portal and such possibility would be a great help to make a ranking.
Another option we consider is making some kind of "wrapper" or proxy for FB like / share buttons which will at first save some data in our database (probably - this user clicked on like for this link) and then go on with standard FB like / share route. Did anybody of You tried such solution?
If You have any other suggestion on the subject, please, post them, we'll be really thankful.
It is possible to know if a user has LIKED a site or not. You can get all user's likes with Graph API (you need user_likes permission). Take a look at the docs: http://developers.facebook.com/docs/reference/api/user/
I'm not sure if you can know if he has shared your site, but you could try by parsing his wall with the read_stream permission and then look for your site name/URL post by post.
For just general liking of items on your site, you can use a Facebook Social Plugin. However, you won't be able to associate (or really even access) user activity with users on your site without integrating Facebook Connect and creating a Facebook application for your site. At that point you can design with greater control all the possible user activity and interleave with your facebook calls other calls that affect users' accounts on your site.
I've done a little searching and was wondering if there is a way to link a users account in our web app with their social media accounts they choose to link (facebook, twitter, etc). i.e. when they log into our web app they are auto logged into facebook, twitter, etc?
I see facebook has an api to login to our web app using their facebook book account but I want it to work the other way around, I want them logged into facebook when they log into their account via our web app.
Thanks,
Ryan
It is definitely possible-from your question I assume you would like to pull data and make actions on behalf of a user? If so, you will need the offline_access permission as well as all the other permissions you will need (check out the list here to see exactly which ones you require). Then, you can trigger a script on your server that tell facebook as soon as the user is logged in to your site, to log in your application as the user as well.
NOTE: You might be going about this in the wrong way. I would advise that you specify a bit more details on what exactly you need the user to be logged in for, and I can (probably) provide you with a decent answer.
EDIT: In response to your question in the comment, Ryan, here is my answer:
You need to divide this problem into 2 different situations-one: your company wants you to write all the code from scratch and don't use what facebook has to offer, in which case you should create a custom login script that enables your users to use their facebook account as the Actual user account in your web app. This is the best solution in my opinion, and is supported by the ever-so-awesome Jeff Atwood. Here's a link to how to do just this, and a tutorial about this also.
Or your company is comfortable with using Facebook's Social Plugins.
Then you should focus on Like Button & Comments : These social plugins are the best way to enable people to create social experiences if they're already logged in.
I'm starting to work on a site that will be strongly connected to a corresponding Facebook app. I want the contents to be free for all to view, but only registered users will be able to edit it (quite similar to serverfault, actually).
Since I think that most of my users will be logged in to facebook, I would really like to use their facebook credentials as to login to my site - the same way Open-Id registration works here.
Can this be done?
Thanks,

Yes, this is one of the things provided by Facebook Connect. There is a wiki full of documentation - start at "Authenticating Users with Facebook Connect".
