1. surround the whole thing in a loop like this
<cfloop from="1" to="#listLen(form.sku)#" index="i">
<cfset currSku = listGetAt(form.sku,i)>
<cfset currQty = listGetAt(form.quantity,i)>
[ place existing code here but replace FORM.SKU with currSku and
replace FORM.QUANTITY with currQty ]
</cfloop>

Subject: CFLOOP and multiple variables
I have a shopping cart system (part of the one that came with CF Server)
and i would like to have users be able to order multiple items with
different quantities. IE a user could order 4 red hammers, 2 blue hammers,
and 5 green hammers in one click of the button.
When they hit the submit button i get these Form variables.
FORM.SKU = 12,34,23
FORM.QUANTITY = 1,3,2
Here is my existing code to add the items, but right now it is setup to add
only one item at a time with one quantity. How can i loop over this code
with the proper SKU, and Quanity for each part of the form variables
list? If i use <cfloop INDEX="loopingSKU" LIST="#form.SKU#"> then all i
can loop is the SKU, the Quantity does not loop.
<!--- If the item is already in the basket... --->
<CFIF ListFind(Session.StoreItems, Form.SKU) NEQ 0>
<!--- Find where in the basket it is --->
<CFSET ItemPosition = ListFind(Session.StoreItems,
Form.SKU)>
<!--- Find out how many of the item are already in the
basket --->
<CFSET CurrentQuantity = ListGetAt(Session.StoreQuantities,
ItemPosition)>
<!--- Now we add one to what's already in there --->
<CFSET Session.StoreQuantities =
ListSetAt(Session.StoreQuantities,
ItemPosition, CurrentQuantity + Form.Quantity)>
<!--- Otherwise, just add it to the basket --->
<CFELSE>
<CFSET Session.StoreItems = ListAppend(Session.StoreItems,
Form.SKU)>
<CFSET Session.StoreQuantities =
ListAppend(Session.StoreQuantities,
Form.Quantity)>
</CFIF>
Any help would be appreciated. Hopefully i explained this without making
it super confusing.
Thanks,
Chad
