I am developing a retail store website. Can someone give me a clue on how I can set up a "shopping cart".
I want to show a "view cart" button, a "check out" button. I also want to show the customer a "item" indicator and a "subtotal" indicator.
When the customer clicks on "view cart", it will show all items place on the shopping cart, the "item" indicator will act as a "counter" and show total number of items placed in the shopping cart, and the "subtotal" indicator to show total amount purchase.
Your best bet is to use some specialist shopping cart software. Whatever you use will have to integrate with your payment processor so start by seeing what they recommend.
I am assuming of course that you have sorted out a processor for handling credit and debit cards. That is something that needs to be done first.
It simplifies a shopping cart and supports many payment processors. You can have all of the things you listed off. You just need to know how to code the links. The site has detailed information on how to this.
I have heard good things about that software but as I said before you need to check that it will integrate with your payment processor before putting any effort into development.
