I am using Facebook's Javascript SDK to post to a users wall.
The code which performs the actual post is:
linkUrl is a fully qualified domain name.
FB.ui({
method: "feed",
link:linkUrl,
picture:imgUrl,
name:title,
"description":description,
actions: [
{name: linkUrl, link: linkUrl}
]
},
function (response) {
if (response != null || response != undefined) {
fadeOutAlert = true;
self.fbMessageLabel.innerHTML = "Thank you, your Facebook post has been successful!";
self.fbMessageDialog.dialog("open");
};
});
The post works perfectly well and appears on the users wall, however the link has Facebooks access_token appended to it. So rather than linking to my.website.com it's actually linking to my.website.com/#access_token=aReallyLongAccessToken&expires_in=5684
Is there a way to prevent the access_token from being appended to the link?
bah.. I have been playing with this for DAYS now.. and just figured it out.
Ok, so for others that may have the same problem..
You need to go to the settings on the app and select the Permissions options.
Then set Authenticated Referrals to disabled, as in the image below. This will stop Facebook adding the access_token to your links.

i am using below code to share fb feed
FB.ui({
method: 'feed',
link: 'https://developers.facebook.com/docs/',
caption: 'An example caption',
}, function(response){ console.log(response); });
response is always null i could not figure out why , i think when share done it must output some response
ref link : https://developers.facebook.com/docs/sharing/reference/feed-dialog/v2.5
Please guide if i am missing something
There is only a reliable callback if you authorized the user with the publish_actions permission. In that case, you will get the Post ID in the callback.
Else, there is no way to determine if a user shared something.
Keep in mind that you are not allowed to reward users in any way for sharing according to the platform policy: How to upload multiple images to one post in facebook via api
I have my site qa.carryon.com (this is our test site). I have configured it for facebook login and send invitations. In facebook I have configured SiteURL as 'http://login.qa.carryon.com/gs/'. 'login.qa.carryon.com' is our CNAME and we are using Gigya as social third party.
Login is working fine and when users see the list of facebook friends, user will click on one of them and the facebook send dialog triggers. The link parameter for send dialog is something like this 'http://qa.carryon.com/loyalty/signup?userid=xghdt6ys&username=xyz'.
For this link am i getting the error code 100 link invalid or there is other issue in configuration. I am doing this for first time and i cant understand whats going on. Please help i am stuck with no clue.
I had this issue as well and I was using dynamic querystring parameters on a common URL. It seems you are doing the same.
I fixed the issue by forcing Facebook to scrape the URL before I attempt to send it via the FB UI Send Dialog. Use the FB API to hit graph.facebook.com with the URL posted in the id parameter and a scrape parameter set to true.
Like so:
FB.api('https://graph.facebook.com/', 'post', {
id: '[URL]',
scrape: true
}, function(response) {
FB.ui({
method: 'send',
name: '[name]',
picture: '[Picture URL]',
link: '[URL]',
description: '[description]'
});
});

Does that help?
I'm making a simple Facebook app that posts updates to the user's timeline using node.js and Facebook's Open Graph API. Even though I can see the posts I make using the OG API on my timeline (and it has the globe icon identifying that it's a public post, see pic below), none in my FB friend network can see it.
Here's a screenie of a public post I made via OG API showing up on my timeline, along with a post from a 3rd party app (Pool practice) for comparison:
Now here's the screenie of my friend's timeline showing only the Pool Practice post, the post from my app is nowhere to be seen...
I've checked the app settings and permissions as well as the OG API options, but haven't seen anything that points to how I can solve this problem. Here's the node.js code I'm using to post the updates:
// app permissions set to 'publish_actions' and 'publish_stream'
// I do the auth dance here to get the access_token and store it in session as fb_token
var request = require( 'superagent' ); // module from TJ Holowaychuk similar to "request"
request
.post( 'https://graph.facebook.com/me/feed?access_token=' + req.session.fb_token )
.send( { message: 'posting via node.js' } )
.set( 'Content-Type', 'application/x-www-form-urlencoded' )
.end( function( response ) {
log( response );
});
The code above works and the post shows up on my timeline, but no one else is able to see it.
Anyone know a way out of this?
you need to submit each action for Facebook validation before your friends can view it. Only users defined as developpers for the app are allowed to view those timeline messages.
If there any way to check in PHP SDK if user can write on specific friend's Wall?
Example:
if ($facebook_can_write_to->'123456789') echo "You can write on this friend's Wall";
Using the FQL table (http://developers.facebook.com/docs/reference/fql/user/) you can check to see if the current user can post to a friends wall by loading up the friend's user information specifically the can_post field.
can_post bool Whether or not the viewer can post to the user's Wall.
According to the documentation you can post on a user friends wall if that user granted you the *publish_stream* permission:
publish_stream
Enables your app to post content, comments, and likes to a user's
stream and to the streams of the user's friends.
There are some cases in which you won't be able to do so, for example if some user blocked your application then I guess it will fail if you try, so you should just check the response you get back from facebook for the api request and see if it worked or not.
Edit
As far as I'm aware you can not ask the api (nor via fql) "can my application post to this users wall", you can only ask "have this user granted my application the publish_stream permission".
If I understand what you want, I might have kind of a solution for you though.
I say show the user the option to post on a friends wall.
When the user chooses this option try to post on the friends wall (and I assume you are using ajax for that call), if it fails return some kind of code, then in the client side check for that code, if it returns use the javascript sdk to open a dialog.
You have two choices for dialogs, you can use the Feed Dialog like this:
var obj = {
method: 'feed',
to: "FRIEND_ID",
name: 'A message',
caption: 'Just trying something',
description: 'This is how to post on a friends wall'
};
FB.ui(obj, function(response) { console.log(response); });
Or you can use the Send Dialog:
FB.ui({
method: 'send',
to: "FRIEND_ID",
name: 'A message',
link: 'LINK_URL',
});
With this one though you have to post a link, I'm not sure if that works for you. After you tried and failed for a user you can save that data and use it later.
I suppose the answer is pretty simple, but i cant find conclusive answer either way.
Is it possible to use facebook to log in a user, fetch their friends, allow them to select them and then post to their profiles in turn, even if that means firing up a custom modal with html to select from the list of users friends before passing the IDs on to the publishStream function in a loop.
Any response would be dandy. Thanks guys and gals.
If you post to the logged-in user's stream, you have no control over which friends see it in their own streams.
Alternatively, you can send facebook notifications to friends that were selected, subject to the daily notification limit imposed on your app by facebook. Be aware that facebook is phasing out noficiations.
You can do exactly what you said. Just get the list of user IDs before hand using your custom dialog you mentioned. Then call the FB.ui function repeatedly, populating the "to" parameter with each friend ID.
FB.ui(
{
method: 'feed',
to: #,
name: 'name of post',
link: 'http://link.com',
picture: 'http://link.com/image.jpg',
description: 'descriptive text',
},
function(response) {
if (response && response.post_id) {
alert('Post was published.'+response);
} else {
alert('Post was not published.'+response);
}
}
);
