Hello I need some help please! I have a web page that currently inserts a record containing customerID, productID and quantity into the cart table if a user adds a product to their cart. However, if the user goes back to the shop and re-adds that same product to their cart. The php/mysql creates a new record regardless of what they have in their cart. Current output in table: customerID productID quantity 1 ABC12 3 1 ABC12 1
