Additional/extra Tab To Products Page In Backend With Own Db Table

[sebastian2]

hi,
anyone out there who would like to give me some helpfull advices?
I would like to create a new tab under the products edit page in the backend to store additional data about a product. In my case it would be multiple links for one product.

 

I used the following tutorial:

http://blog.belvg.com/how-to-create-a-custom-product-tab-in-prestashop.html

 

After the Tutorial I now have a new tab and a new DB-Table. Everything works but obviously I can store only one link per product.

So now the next step would be to build a List/Add/Edit/Delete Panel in the backend for the links.
But I got no idea how!

Thanks a lot in advance!
