Hi Thomas,

I often hook into the save and publish node events to perform some operations. Here is how I hook into them. I have this file that gets compiled into a .dll that I put into my /bin folder. It's named "NodeHooks.cs". In there :

using System;
using System.Linq;
using Umbraco.Core;
using Umbraco.Web;
using umbraco.BusinessLogic;
using umbraco.businesslogic;
using umbraco.cms.businesslogic;
using umbraco.cms.businesslogic.web;

namespace MyNamespace
{
    public class NodeHooks : IApplicationEventHandler
    {

        public void OnApplicationInitialized(UmbracoApplication httpApplication, ApplicationContext applicationContext)
        {
            Document.New += DocumentNew;
            Document.AfterPublish += AfterPublish;
        }

        public void OnApplicationStarting(UmbracoApplication httpApplication, ApplicationContext applicationContext)
        {
        }

        public void OnApplicationStarted(UmbracoApplication httpApplication, ApplicationContext applicationContext)
        {
        }

        static void AfterPublish(Document sender, PublishEventArgs args)
        {
            if (sender.ContentType.Alias == "OfSomeType")
            {
                // Do stuff
            }
        }

        static void DocumentNew(Document sender, NewEventArgs e)
        {
            if (sender.ContentType.Alias == "OfSomeType")
            {
                // Do stuff
            }
        }

    }
}

Inside those events, you can access node properties with sender. So I think you could try and code some "PushToFacebook" functionnality in there, but I'm unfamiliar with what would be needed to do that. But if this works for you, post the details here I would be very interested!

Hope this helps!

Hi Seb!

I have the event part sorted out, but thanks for posting an example!

The problem I'm facing has more to do with Facebook and the integration of Facebook with Umbraco. In our case it could take a long time (hours/days) between the time the user connects with Facebook and gives permissions and the time when the node is published and the message should be posted to facebook.

I've found an article on Facebooks developer site that talks about something called an App Token which doesn't expire:

https://developers.facebook.com/docs/technical-guides/opengraph/publishing-with-app-token/

...and it seems like this kind of token can be used to post stuff to a user feed eventhough the user is not currently logged in to Facebook. More about the different app tokens can be read here:

https://developers.facebook.com/docs/concepts/login/access-tokens-and-types/

Ok - so there might be a way to get permission to do the actual post. The second part of my question has to do with the actual method of interacting with Facebook. Normally when we do Facebook integration on a website we use the JavaScript SDK. In this case I don't think that's possible since all that will be executed is ASP.NET code on the server, like in the example Seb posted. So I guess this means that we'll need to do authentication and interaction with Facebook though 100% ASP.NET code(?) Is there anyone who has some experience of this? Are there any good libraries out there that we shoudl try? Are there libraries that we should stay away from?
