[TYPO3-dev] Need hint to make a recursive copying function

[Brian Bendtsen]

Hi

Im working with the commerce extension. This is not so much a commerce 
question, but more related to programming so I will ask it here.

I have extended the tx_commerce_categories with a field so I can attach 
contact persons to a category.

Now, I need some way of making it possible for the webmaster to attach a 
contact(s) to a category and let him decide if the same contacts should 
be attached to subcatgories one, two or infinite levels down.

What would be the smartests approach, do someone know an extension that 
does something similar?
