Simple Shopping Cart

[noah_britton]

I am trying to develop a simple shopping cart.
I have created an array of structures for this as follows.
<cfif not Isdefined("Session.ShoppingCart")>
<cfset SESSION.shoppingcart = ArrayNEW(1)>
</cfif>

<cfset additem = StructNew()>
<cfset additem.id = FORM.id>
<cfset additem.name = FORM.name>
<cfset additem.color = FORM.color>

<cfset arrayappend(session.shoppingcart, additem)>

I would like to delete a given entry in the array given a particular FORM.id, say id = 220
Here is my code to try and delete the item
<cfloop from="1" to="#ArrayLen(SESSION.shoppingcart)#" index="i">
<cfif SESSION.shoppingcart .id eq FORM.id>
<cfset foo = structdelete(SESSION.shoppingcart, id)>
<cfelse>
</cfif>
</cfloop>

This is not working. I guess perhaps I should delete the array entry, but I can't figure out how to do this. Thanks in advance. -Noah

Duh, I figured it out.
<cfset bar = arraydeleteat(SESSION.shoppingcart, i)>
I am having a problem when looping not sure why. I think because I'm deleting an item in the array it tries to loop to that index in the array. It will say "The element at position 3 cannot be found". I guess I normally wouldn't have to delete multiple positions in the array with a normal shopping cart unless they selected two different id's. I'll work on a more advanced shopping cart and post again.
