Can anyone please explain to me in lay-man terms how the code below works!
It is a function for adding items to the shopping cart. I am trying to use
the same concept to have customers add item sizes as well as they add the
items to the cart but i am missing something!
*VIEW*
<br />
<span id="{{='item%s'%p.id}}" style="font-weight: bold; color: red;">
{{=session.cart.get(p.id,0)}}</span> in cart - {{=A('add to
cart',callback=URL('cart_callback',vars=dict(id=p.id,action='add')),target='item%s'%p.id,_class='button
pill')}}
<br />
*CART VIEW*
</td></tr>
{{for id, qty in cart.items():}}{{p=db.product(id)}}
<tr id="boughtItems">
<td><span style="font-weight: bold;">{{=p.item}}</span></td>
<td><span style="font-weight: bold;">{{=MoneyFormat(p.price)}}
</span></td>
<td><span id="{{='item%s'%p.id}}" style="font-weight: bold;">{{=qty}}
</span></td>
<td><span style="font-weight: bold;">{{=MoneyFormat(qty*p.price)}}
</span></td>
<td>
*CONTROLLER*
def cart_callback():
id = int(request.vars.id)
if request.vars.action == 'add':
session.cart[id]=session.cart.get(id,0)+1
if request.vars.action == 'sub':
session.cart[id]=max(0,session.cart.get(id,0)-1)
return str(session.cart[id])
