Hello,
As the staff at the company I work for were used to clicking on the product name inside the invoice and it opening a window and showing the product details on the normal customer area with the existing system we had, I created this simple code change to enable it to be done.
1. Open skin1/mail/html/order_data.tpl.
2. Find :-
2. Replace it with :-
Remember: Replace yourstoreurl.com with the actual URL of your store.
That works fine or me so should for anyone who trys it.
Best Regards,
Craig Brass
