I have a web site that accepts visitors registerings.
I want to all a choice in the registering form :
[] Like our page on Facebook.
so if user checked this option in registering, a request will be send to facebook to like this page
I also imagine
[if he was already logged on in facebook, if not just ignore the request.]
[this request can be done with ajax.get or ]
At this point of time, the ability to "like" a page is strictly allowed only through facebook's own interfaces (site, app etc) and cannot be done by the API or third party apps. I believe that facebook may not allow it in near future too since it may open up serious privacy issues.
You might be better off putting a like plugin in your registration process if that is one of your targets.

So here's my use case:
A user sees a cool product on a shopping website (sample-shopping-site.com)
They want to share this product with their friends on facebook
They however want to pass the information to an intermediary site (a-sharing-app.com - that i'm trying to develop), that posts to facebook on my behalf.
My questions:
Is this even allowed by facebook? i.e. can a-sharing-app.com put a widget on sample-shopping-site.com, so that a person visiting sample-shopping-site.com can share on facebook via a-sharing-app.com?
If yes, could you point me to helpful bits on the facebook developers API page?
Just want to clarify: the APIs and most questions/examples on the internet point towards sharing directly from sample-shopping-site.com to facebook, by registering sample-shopping-site.com as an App with facebook.
I however want to register a-sharing-app.com as an App, and then putting a widget of a-sharing-app.com on any page (such as sample-shopping-site.com) allows me to share on facebook by passing information to a-sharing-app.com
As far as I know there is no Facebook guidelines that restrict what you want to achieve, so I may safely say that yes, you can create an app so that a person visiting sample-shopping-site.com can share on facebook via a-sharing-app.com . I can even mention a well know service that is doing the same, Disqus.
How you can implement this feature is a little up to you but may I suggest what Disqus or apps like it are doing is, they use the JavaScript API of Facebook to integrate and are mostly enabled within an iframe that loads content from their domain. The exchange of information between sample-shopping-site.com and a-sharing-app.com is done by the JavaScript loader which loads the necessary iframe then. The other things you would like to check would be Dialogs which you may use for different cases, or you may do it on your own using the FB.api and make API calls to the Graph API for sharing data.
I'm a web developer and i'm having problems using the "like it" button
I put the buttom on my site as a counter of votes of a special contest. People can only click the like buttom if they are fan of my Facebook page.
The problem is that people can't vote if they haven't public permissions on his facebook, cause i can't know if they are or not fans of my page.
Is there a solution?
if you rely on information that you are not certain that you can obtain then sadly there is no solution.
Since what you are doing is beyond a simple like button What you may want to try is open a facebook application and request from your users the user_likes permission. You can read more about it here. I have photo albums on the "highest privacy setting" - only me. Yet when I request a list of my photo albums through one of my applications (with the required permissions of course) I get back ALL of my albums.. This might have been a temporary issue that was solved - but in any case - I saw this behavior and I thought it might be relevant to this post :)
Additionally you should look at the Promotions Guidelines specifically this point :
You must not use Facebook features or functionality as a promotion’s registration or entry mechanism. For example, the act of liking a Page or checking in to a Place cannot automatically register or enter a promotion participant.
I had some problems with facebook on this issue - you are not allowed to require someone to "like" a page in order to participate in an activity that is not directly connected to that page.
From what I understand you are requireing people to like your page on facebook beofore voting on your site... If this IS the case then facebook might very well start taking action and closing your page/app.
I'm trying to get a user to 'Like' a page via the SDK. User is signed in and I get a valid access tokken form the cookie. My APP has asked for permissions read_stream and publish_stream. I can successfully do things like post to their wall, etc. But when my APP tries to 'Like' a page, I get the error back:
OAuthException: (#3) Application does not have the capability to make this API call.
Am I missing some other permission, or is there a setting I have to turn on in my APP? I'm at a loss here.
You can't like a Page on behalf of a user (Bugzilla discussion). You can, however, like posts, comments, and photos on behalf of a user.
Edit 7/9/2012
Since bugzilla no long exists, the bug linked above is inaccessible. Google doesn't have a cached version of the page, so I ran another search. The best thing I could come up with was this Google Code Discussion regarding the ActionScript API.
Facebook makes brief mention of Publishing likes via the Graph API in the documentation, but doesn't say one way or another whether you can like a Page on behalf of a user - just "Objects" which (probably arguably) are not "objects" in Facebook-lingo.
My thought is, the API to like page is available, but is only offered to white listed applications (such as, the Facebook iOS and Android applications) written by "special" publishers. There's obvious reasons why Facebook wouldn't want/allow developers to create like connections on the graph. It would be taken advantage of by spammers and other nefarious developers and would deteriorate the meaning of what a "like" represents for a page on Facebook.
My guess is, you'd have to make a pretty strong case to Facebook about why you need/want access to the Page's Like connection (for publishing) before they'd even consider giving you access. I'd also guess that they'd want to verify that you're doing only user initiated like creations (in such a way that the iOS application would handle it) so as to protect the reptutation/meaning of a "like" action.
Actually this is NOT true, but you have to do a complicated Javascript / UIWebView process in order to display a Facebook 'page' of JUST the like button on your view, and this like button you can configure in the JavaScript / Objective-C (using string replacement) to be any Facebook page url you like.
Facebook's platform policies don't allow for a web-based like button aside from using the officially supported options
Those options doesn't require using OAuth or the Open Graph api. However, facebook just added support for mobile apps to send like actions through opengraph.
I'm not sure if they intend to allow sites to customize their like buttons or just apps...
Liking works for me with the iOS SDK using the graph api:
https://developers.facebook.com/docs/opengraph/actions/builtin/likes/
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.
