Creating Child Nodes on Page Save

Hello,

I'm currently using Umbraco 7.2 and I'm trying to create an application event on the Saving event to automatically create 4 child nodes on the page I've just saved.

While I believe I've got the Event handler right, I don't know what code I need to create these child pages.

So:-

> Home

>> My Section

>>> Parent 1 (So I create this page as a child page of 'My Section')

>>>> Sub 1 (These pages should be created automatically)

>>>> Sub 2 (These pages should be created automatically)

>>>> Sub 3 (These pages should be created automatically)

>>>> Sub 4 (These pages should be created automatically)

Any help will be greatly appreciated.

Thanks

Paul

Answered my own question:-

var savedEnts = e.SavedEntities;

int parentID = savedEnts.Select(x => x.Id).FirstOrDefault();

string folderName = savedEnts.Select(x => x.Name).FirstOrDefault();

IContentType templateType = savedEnts.Select(x => x.ContentType).FirstOrDefault();

bool IsNew = savedEnts.Select(x => x.IsNewEntity()).FirstOrDefault();

if (templateType.Alias == "Profile" && IsNew == true)

{

ContentService c = new ContentService();

var content = c.CreateContent("Sub 1", parentID, "Content");

content.SetValue("pageTitle", "Sub 1");

c.Save(content);

content = c.CreateContent("Sub 2", parentID, "Content");

content.SetValue("pageTitle", "Sub 2");

c.Save(content);

// Create Media Folder

IMediaService mediaService = ApplicationContext.Current.Services.MediaService;

var newFolder = mediaService.CreateMedia(folderName, 1110, "Folder");

mediaService.Save(newFolder);

}

Hi Ido,

Have you ever figured out where exactly to add Paul's code ?

I need to do something similar but I'm not sure where exactly to start with.

Thanks.

Hi Elin,

I created a new class 'ApplicationEvents' which inherited IApplicationEventHandler

In this class you can you can create a function called: ContentService_Publishing and add the code there.

Cheers Paul

Thanks for replying Paul,

Where is the ApplicationEventHandler located exactly? I think that's what I'm having the most trouble with, as I don't know where to find/create this file.

Thanks.

You need to create it yourself. If you're using Visual studio just create a new class call ApplicationEventHandler and add the:-

using Umbraco.Core;

to the head

 public class ApplicationEvents : IApplicationEventHandler { }

Then add something like this :-

public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { ContentService.Publishing += this.ContentService_Publishing; }

And then put the code in a function like this:-

public void ContentService_Publishing(Umbraco.Core.Publishing.IPublishingStrategy sender, Umbraco.Core.Events.PublishEventArgs<IContent> e) {}

Hi Elin,

You'll need to create the class yourself.

In Visual Studio create a new class called: ApplicationEvents

public class ApplicationEvents : IApplicationEventHandler {}

Give it a using of Umbraco.Core

Create another function like this:-

public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { ContentService.Publishing += this.ContentService_Publishing; }

Then finally create your function and the code from my original post.

public void ContentService_Publishing(Umbraco.Core.Publishing.IPublishingStrategy sender, Umbraco.Core.Events.PublishEventArgs<IContent> e) { }

Hope this helps

Thanks

Thanks again.

Ido, at least in Umbraco 6.1.0+ you need to do something like the following. It is done a little differently in older versions.
```
public class MyUmbracoEvents : ApplicationEventHandler
{
    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ContentService.Saved += CreateChildNodes;
    }

    private static void CreateChildNodes(IContentService cs, SaveEventArgs<IContent> e)
    {
        // all that stuff he did goes here.
    }
}
```
Make a class that inherits from ApplicationEventHandler and on ApplicationStarted, register some saved event handlers.

Here is some documentation about registering these sorts of events. It talks about how to do it in various umbraco versions: application-startup - events & event registration
