Well... I think I probably owe most of the people on this list some serious cash in
consulting fees by now. But we're opensource, so I guess I'm off the hook, right? =)
Anyways, another question for you people. I'm on the last leg of designing this
e-commerce site. All I have left to design is the shopping cart.
How I've set it up to add items is quite simple. The data is posted <add to cart> and
stored like this:
$cart[$prodid] = $my_qty;
cart is the registered variable in my sessions. prodid is the product id, and my_qty
is the quantity. now say a user wants 2 items with the id of 111 and 1 item with the
id of 898. it should have the data stored as so:
$cart[111] = 2
$cart[898] = 1
now.. had i been more experienced with arrays, this would not be hard. but.. i'm not
sure when the user goes to check out how to walk through the data.
basically i need to pull out each index (which is the product id number) as it's own
variable and the qty that corresponds with it as it's own variable.
>From there, although irrelevant to what the array, there variables will be passed in
>a mysql query to get the info to display in the basket (ie- name, description, price).
so, i figure i am going to have to loop the array to extract the info. this would
probably be best since i'm going to be making seperate queries on it as well.
loop until all indexes have been accounted for--->
get prod id and qty from next instance in array, into $prodid and $qty
query the db with the prodid
display results
end loop -->
so.. i'm fine with the query and display, i just need to know how to get each instance
into a variable in a loop.
thanks a lot
