add new shipping rule for overnight
I have already set up my shipping rules for parcel post shipping to the US and outside US. Now the client wants to add overnight. Not sure how to proceed with this using ecart. I added a check box on the check out form for overnight in US only it is named:<input type="checkbox" name="next_day_ship" id="next_day_ship" />
What are the next steps in the confirm.php that I need to implement so if the box is checked overnight shipping overrides my other rules for the US. In my shipping rules I am using the session variable: $_SESSION["eCartCheckoutForm_country"]
the overnight shipping will be a flat rate of 20.00
Thank you,
K
