The Version without Banktransfer still didn't work in my installation.
So I took the only working version here (that was the french) and put the german Formular in it. Now it is well usable.
I found out that the prices don't show up correctly when they are changed by Product attributes.

TODO:
*osCommerce coding standard generally not observed
*clean up code
*replace print("HTML CODE") with HTML code blocks
*tables are sometimes accessed with constant names sometimes directly
*no language support
*uses own db functions
*filter orders by status
*force manual entry of order id instead of combobox if too many orders
*Add the abiltiy to change the Delivery address separate from the Billing address
*Add USPS and Fedex Shipping options if selected via the rest of the admin module
*Add UPS worldwide shipping
*Change the shipping options (RDP, CP, RES) to utilize the set variables from the Admin module
With this file you will be able to edit a customers order to include their e-mail address, billing address and now includes many more shipping options.
The configuration has been redesigned to make installation easier.
There are many other functions I want to try to incorporate into later versions.
Yup thats about all.
This is a very early-release tool that works on OSC 2.2's database, but I needed one to update my completed orders. At this point, the code should be very readable (I have a short "guide to my code" in there), so you can make any changes necessary to make it fit your purposes.
To use the tool, just save it to your catalog directory or whatever you named it, edit the file so the right database information is in there, and then go to the page in your browser.
From there, select the order you want to modify from the drop-down list and click the button next to the list, and the order details should appear. You should be able to update each product on the order, add products to the order, delete products from the order, and change the shipping to either "Store Pickup" or "UPS Ground" - totals are re-calculated and the order is updated.
Again, be careful, this is a tool not necessarily meant for everyone, and you should use it for basic updating tasks.
Enjoy.
