Fb.ui post to wall - facebook

Question

I am using the code below just as from https://developers.facebook.com/docs/reference/dialogs/feed/ to post to a users wall. However the post does not appear on the wall. Is there something I'm missing?
FB.ui({
method: 'feed',
link: 'https://developers.facebook.com/docs/reference/dialogs/',
picture: 'http://fbrell.com/f8.jpg',
name: 'Facebook Dialogs',
caption: 'Reference Documentation',
description: 'Using Dialogs to interact with people.'
}, function(response){});
I have the Javascript SDK connect.facebook.net/en_US/all.js loaded. Do I have to add the following code?
FB.init({
appId: 'xxxXXxxx',
status: true,
cookie: true,
xfbml: true
});

Answer 1

There are many reasons why it might not work. The information you provided is really not sufficient, so I'm just gonna go ahead and list a couple of reasons why it might not work:
make sure you created an application on [Facebook developers] (https://developers.facebook.com/apps/), and have the Site URL correct along with the App Domains
the "xxxXXxxx" in the FB.init() is the application ID generated while creating an app on Facebook.
If you're trying on localhost, it will never work.
Finally, your code should look something like this:
<div id="fb-root"></div>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({
appId : 'xxxXXXxxx', // App ID
channelURL : '../../Vendor/channel.php', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
oauth : true, // enable OAuth 2.0
xfbml : true // parse XFBML
});
function postFeed(){
FB.ui({method: 'feed',
picture: 'https://www.example.com/img/fb-post.jpg',
link: "http://www.example.com/",
caption: "example.com",
description: "a small description associated with your post",
}, requestCallback);
}
// Load the SDK Asynchronously
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol
+ '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
