Database driven shipping
I've a working live eCart5 with 3 shipping rules, one for UK, one for Europe and one for the rest of the world. I need to add DHL shipping based on type of delivery, where to and based on the weight(s) of item(s). DHL UK have said they don't use an API solution and have supplied two spreadsheets instead. One is for 3 domestic tariffs and the other for 3 international tariffs over 9 zones.
I've gone back to the tutorials "Database-driven Sales Tax and Shipping" and can't see how anything links to a database.
Is there another tutorial to follow or should I simple work out how the spreadsheet is calculating each value and add the calculation into the shipping part of the eCart object?
If it's the latter can you walk me through how to do this?
