I am looking to extend the CMS for the blog entries. I want to allow a few more fields (like a header image for example) when the user enters a blog entry, and remove some of the fields normally associated with the "Page" type, as they don't apply to my blog.

I know it's best not to add these in the blog module, so that when it gets upgraded, I won't lose my changes. What is the best way to extend this module?

I've need to do exactly the same thing, can anybody help us?

The best way to extend module / core functionality is to use decorators.

Dan, To answer your specific issue - you should be able to customize the CMS within a decorator by using the updateCMSFields() function. See

Hi Willr,

That's all I needed to know. Where do I put my dataobjectdecorator code?

You can create a new file in mysite/code/ for the decorator.

Can I remove fields/CMS tabs using the data decorator? If so, how (the documentation shows how to add fields only), and if not, what's the best way to do that?

Yes, as it says on the dataobjectdecorator page you can define a updateCMSFields(&$fields) function. You should be able to then call any of the usual cmsfields functions -

Maybe I am doing it wrong, but I am trying to remove 2 tabs from my CMS for all blog entries, like this:

public function updateCMSFields(FieldSet &$fields) {

And nothing is happening. Can anyone tell me what I am doing wrong here?
