Hi
I'm creating my own Object Oriented PHP Shopping Cart.
I'm confused about the best way to call the functions of the class given
the "static" nature of the web.
For example, if I have a function addItem($code), how will this be
called from the catalog or product description pages where the BUY
buttons are?
On the product description page (say for product ABC213), there will be
a BUY button, but when the button is clicked, obviously I cannot
immediately call $cart->addItem('ABC213'). So how is this done?
I thought of making the BUY button link to the cart itself, like so, but
doesn't this mitigate the whole point of designing with classes:
<a href="Cart.php?action=add&code=ABC123&goto=viewcart">BUY</a>
The Cart.php would then redirect the user to view the contents of the
shopping cart.
Do you have any tips, or are there any resources that may help me think
more clearly about this?
My aim is to build a Cart that is very flexible that I can use in many
situations in the future.
Thanks for your help.
S.
