#givemewhisky actually in nayelli she has no cart system but in my site I am using cart system where user can add product which he/she would like to buy and after adding all selected products into the cart then he/she can move to the cart page where their would be a button down at our cart products list “checkout” and when user click on that button then the item’s in “Cart” database would be added into our createPayment() items objects.
Here is the link of the website from where you can see the functionality of the site
