On my site I want members to be able to click a link import your Facebook photo then a Facebook popup opens and asks user to confirm that he/she wants to share their profile picture with my website.
Can this be done? What are the steps? I am looking at the Facebook graph API but I am unsure if this is the right thing, I have huge problems understanding their samples and "help" files.
I was able to easily do this with Gmail and Yahoo, uses can get a browser popup from them in order to confirm sharing contacts with my website, I assumed Facebook works the same to import the profile picture but I am spinning in circles.
Within Facebook Terms for users it states that your name and picture are publicly available so one does not need permission to request it.
https://www.facebook.com/about/privacy/your-info
The naitik call is an example of data that is publicly available without asking for permission.
When you are requesting the current user, that is, you don't know the id or name beforehand, then you use a basic login flow which will then present one of the following dialogs.

We have a platform where users get logged in with Facebook. Now on customers demand, we want to provide a feature where we will request logged in users profile link at the time of login via user_link permission and user can share that link to anyone with just one tap. And on the other end, the other user who will receive this link will able to see (on facebook app or on Web) the sender's profile and if interested they can get connected.
But the issue is, I am not able to see user profile got as user_link. Its seems like I can only use this link if he or she is already my friend. If so then how can I implement this feature in my app? also if I am wrong at any point please correct me.
Its seems like I can only use this link if he or she is already my friend.
That’s exactly what the documentation says, https://developers.facebook.com/docs/graph-api/reference/user:
link: A link to the person's Timeline. The link will only resolve if the person clicking the link is logged into Facebook and is a friend of the person whose profile is being viewed.

If so then how can I implement this feature in my app?
You can’t; Facebook has deliberately designed this feature with this restriction, to better protect people’s privacy.
As far as I know, you can only tag friends of the account associated with the access_token currently in use. This means that if I want to be able to make an app to share photos on facebook with a tagging functionality, it's mandatory that I make an authentication system, where the user needs to type his password to login on FB and I request and store his sixty_days_access_token. This approach is fine for web apps, but is troublesome if I have to implement a desktop touchscreen interface where the users interact with the system in an environment where anyone can watch him typing his user and password. I'm facing this problem with a public touchscreen, where the users can take pictures and send it to Facebook. The interface is implemented with C++ and the curl library. As the touch is in a very crowded environment and the screen is big, we experienced that the users are intimidated to enter his acc/pass. We worked around this problem by creating a fan page to the event where we store all the photos. As we already have the fan page admin access token stored, we don't need to login the users but clearly we are not able to tag any of the user friends, which vastly reduce the viralization potential of the solution.
So, having this problem in mind, how can I face this?
Do I really need to make an authentication of the users to be able to
tag their friends?
Is there any creative solution?
Yes, if you want to tag a user or their friends in a post, you need them to log in - this is a requirement of the Photo tagging API.
The only alternative i can think of is to give the user a URL they can go to later (e.g. on their phone or PC) which will prompt them to authorise your app and do the tagging at that time.
I am designing a website that will be heavily integrated with facebook. Members connect to the site via their facebook accounts and facebook authentication/permission is used to access their friends list and other information.
There are instances in which I would like the site to be able to send facebook inbox messages to selected people from the user's friends list (in a user initiated manner).
I have discovered that this is not possible through facebook permissions.
One idea that I have is to have Facebook's "Compose New Message" popup to appear overlayed on top of my site (as would appear when clicking the "Send new message" button on a user's profile page). The user would then type a message and press send (hopefully circumventing the permissions issue).
I have browsed the facebook developer docs and forums, but my technical knowledge is limited. I just want to know if this is possible or not, and to be pointed in the direction of material on how this could be achieved (so that I can pass this on to hired developers once I reach that stage)
Any help or suggestions on alternatives would be gratefully received!

The closest you can be to your goal is using the Send Button. However, this button is used to share links, which are usually open graph pages. What you can to is specify a dummy href/link so that it shows a blank page. Or, better if you actually needed a link attached, then you have no problem.
There is no way of doing it using Graph API Message Object. There are no publishing rights to this object whatever permission you ask from the user. It is read-only. Just look at the extended permission it is only read_mailbox - "READ_mailbox".
Even FQL can't help us with this.
Also, facebook is in the process of migrating to a new messaging system. So playing around with is now is not advisable.
What you can do now is utilize the Send button I mentioned above.
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 built a survey and at the end i want the users to share their result on their facebook wall but i'm finding it hard to find any examples or reference.
something like;
<div>
[ image/graphic ]
"I've just completed survey XXX and got 90%"
<a>post on my wall</a>
</div>
any help appreciated - even if its just terminology i can look up!
Start here. Basically, you're creating a website which you want to integrate into Facebook. To do so, your users will need to "login to Facebook" from your site (unless they're already logged in, such as in another browser tab) and allow your site to perform certain actions on Facebook on their behalf.
The Single Sign-On part is where you will initialize your website as a Facebook application (you'll need to create the application on Facebook first) and provide a login button for your users.
Your login button can be set up to ask the user for specific permissions to act on their behalf with Facebook. I think the one you want is publish-stream but I'm only barely familiar with it, play around with the functionality and see what works best for you. Your users will be presented with a pop-up div stating that your website (or application) is requesting these specific permissions and they have the option to allow or deny. An example can be seen here.
Once you have the user's permission, you make use of the cookie (demonstrated using PHP back on the Single Sign-On link) to gain access to information by use of the Graph API, the JavaScript SDK, Social Plugins, etc.
you should use the facebook api.
Get the "publish_stream" right of a user and use the "api" method of the connection object (with parameters like : '/userid/feed', 'post', array of informations about the post).
I can't find the right code and the official document is not always up-to-date.
OR
Just add a facebook "share" button on your page that uses "meta" markups. You should find examples on about 80% of websites.
