Add To Cart/Proceed To Checkout/etc.

You know those things that have "Add to Cart", "Proceed to Checkout" and stuff? Well, i need some help on creating a site with the "Add to Cart", "View Cart", and "Proceed to Checkout" options

If anyone can help, that would be apprecxiated.


NOTE: If you have seen this on another post, i would appreciate it if you gave me a hyperlink or the name of that post.

I made a site that has those features recently in PHP. I used a cookie to store the item id and item quantity in. Is this the sort of thing you're looking for?
