Where is the controller that handles the orders shown in the backend?

[David Bucur]

Hi,

I am using a module called Marketplace where the users can become shops. I modified the core in order to have a list of shops so now a Supplier is considered a shop.

 

I need to modify the orders page in the backend so I can put a new column in that table where it states which products from which shop are in that particular order.

 

I am trying to find where that list of orders is created in order to query the database to get the extra data and put into the column.

 

So far I managed to find where the header is created.

 

adminXXXX\themes\default\template\helpers\list\list_header.tpl

But this header is used for all the backend pages with a table.

 

It goes throughout a foreach on $fields_display, but the $fields_display gives me no clues.

 

The attached images are an idea of what I am trying to build.
