Hi, how to add a checkout function to this code? In the picture you can see, I had call the member list and cart function together. I want it automatic execute INSERT INTO query when I click the checkout function. I already make a cart and member list and both are work fine. I don't know how to insert the cart item and the selected member detail to the database. Anyone can show me where should I add the code and how to write the code?
I don't know how to call my cart item name,quantity and total when I want to do the INSERT query =(
