post content to facebook to users' wall? - facebook

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.

Facebook Like button for one facebook page of an app from it's own ios app

I am looking for Like Button to be shown in my ios native app, users of that app have already connected to app via facebook account.
there are several questions related to Facebook Like Button on stackoverflow but those are not specific to authorized single facebook page of the app.
According to official doc of facebook, facebook pages can not be liked via built-in action o open graph api.
But want only one official facebook page of that app to be liked by user when he hits like button. i don't want user to navigate away from the app or login again in web view to like facebook page.
is it possible to like app's facebook page without promoting user to log in again in webveiw?

"the general consensus does seem to be that you can't like a page on behalf of the user, however I just had an ios game like a page on my behalf. Extreme Road Trip successfully manages to get you to like their own page. I wish I'd paid more attention when I did it now..." – wallacer
This still can't be done directly using the graph api ( to the best of my knowledge ). What you can do is open a webview to the page you want the user to like. If you're rewarding their liking your app or something, when they close the webview (you'll have to provide a close button), you can use the graph api to check whether they like your app page. As far as I can tell this is the best current solution - and seems to be the approach taken by mobile games.
That said, I haven't used Facebook SDK 3 yet, so there may be something in there that could help you.
It appears that Liking a page on behalf of a user is still impossible. I've glanced over the iOS SDK Reference, and it doesn't seem like there is a built in mechanism to like anything.
However, in reading one of the other posts you linked to, and remembering that Facebook opened up the Like open graph action so app developers could allow their users to like content generated by their application...I found this link about built-in-actions (likes).
According to that link, you can post Like actions to your users by POSTing to https://graph.facebook.com/<user_id>/og.likes with the POST params for object (the open graph object URL you want to like on behalf of the user in this case your page's url. eg. www.facebook.com/yourpage) and access_token (obviously, for your user).
I'm not totally convinced that will work; though it is conceivable. My second thought would be to create an Open Graph Object for your page, and have all your users like that. Though, that is a little less ideal, as it removes the possibility of people finding your Page while they're on Facebook and would require you to put a lot more effort into getting likes for the Page via your website, application, etc.
I hope that helps a bit, good luck.

Integrating facebook 'compose new message' popup into my website

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.

Liking a page on behalf of a user?

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:

Check whether user of non-facebook app likes/shares particular URL on FB

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.

Facebook page apps - Authorizing a user

I can't seem to find exactly what I'm looking for. We're trying to build an app to run solely on a Facebook Page. We want to show a landing page if they don't Like the page, and the contest entry form if they do. This functionality works.
Before showing the contest entry form, we'd like to authenticate the user viewing the app so that they can just hit "Enter the contest!" and we can automatically pull a name/email address.
Any of the methods of authentication I've seen described, including through the Facebook Developer docs, don't work at all.
I saw something that said they need to interact with the app first, then you can get the id, but that doesn't work either. I also don't get the page id passed with the signed request.
Its also pretty unclear whether I should be using an iframe or just FBML.
Could anyone point me in the right direction, please? Thanks!
You need to create a fan page and add the FBML plugin to that page, then you will need to insert a short code that will determine if a facebook user has clicked 'Like' or not and by determining that you will decide weather to display the content of the landing page or not (using an iframe). You will probably like to also set the FBML box that you create as the default view for members who didn't press the 'Like' button yet, you can change the default view in your fan page settings.
On the iframe, you will need to use the Facebook API if you want to retrieve any user information from Facebook, for that, you will need to register a new application with Facebook. Go to developers.facebook.com for the API integration and app registration.
Also, what do you mean when you say:
Any of the methods of authentication
I've seen described, including through
the Facebook Developer docs, don't
work at all.
Well, it appears you can't do it that way. The client was very specific in wanting that functionality but we ended up convincing them to go for a redirect to the canvas page to have the app authorized and the contest entered instead.
