Facebook app, post status after allowing access

Question

Provided that when the user connected / logged in to your app/game you have asked for the correct permissions it should be pretty easy. Below is some code I wrote for a project of mine. The user would have had to specifically allowed the app to publish to the stream on their behalf.

Pay special attention to the :

{scope: 'publish_stream'}

This will ask the user during the connection phase if it's ok for your game/app to publish to the stream on the users behalf.

// Click Handler for the login. 
$(document).delegate('#fb-connect', 'click', function(e){
    e.preventDefault();
    FB.login(function(response) {

    // Check the status
    // console.log(response.status);

    if (response.status === 'connected') {

       // Run the function we created below to publish to the users stream.  
       publish('I just logged in via Facebook. '); // Your Message 

    } else if (response.status === 'unknown' || response.status === 'not_authorized') {
        // Something else if they chose not to connect
    } else {

    }

    }, {scope: 'publish_stream'});

});

This is a simple function that you can pass a string to (your message) and will post to the currently connected users stream.

function publish(messagebody) {

var body = messagebody; // This is the passed in string aka message you want to post. 


params = {
    message: body, // Your message body
    link: 'http://www.yoursite.com' // if you want to share a link. 
}

FB.api('/me/feed', 'post', params, function(response) {
  if (!response || response.error) {
    //alert('Error occured');
    console.log(response.error);
  } else {
    // Successful post to facebook.
    // alert('Post ID: ' + response.id);

  }
});
}

Hope this helps you!

        });

        // Additional initialization code such as adding Event Listeners goes here
