Sorry, typo ... The first line of the script should look like:
function removeItem(myarray,rem){

Subject: RE: another pair of eyes on this CFScript, please
1. VAR your counter variable (i) - just for good measure.
2. To use variables inside a function you have to either pass them in or
create them in the function. So most likely CART and URL.REMOVE aren't
available to the function. You'll need to pass them both to the function
to use them.
3. After you change the array, you'll need to pass it back out to the
template as its been updated and its length has been changed by
ArrayDeleteAt()
Try this:
<cfscript>
function removeItem(array,rem){
var i=1;
var removeprice = 0;
for(i=1; i lte arrayLen(myarray); i=i+1) {
if (myarray[i].ITEM_ID IS rem) {
removeprice=myarray[i].PRICE;
ArrayDeleteAt(myarray, i);
break;
}
}
return myarray;
}
</cfscript>
Call it with something like:
<cfscript>cart=removeItem(cart,url.remove);</cfscript>
That should allow you to pass in your array and removal item, remove the
item if necessary and then pass back out the updated array.

Here it is:
function removeItem(){
var removeprice = 0;
for(i=1; i lte arrayLen(cart); i=i+1) {
if (cart[i].ITEM_ID IS url.remove) {
removeprice=cart[i].PRICE;
ArrayDeleteAt(cart, i);
break;
}
}
}
As near as I can tell, nothing inside the "for" loop is executing.
I've tried replacing arrayLen with a hard variable, I've tried GTE ...
but if take everything out and do a writeout(), nothing appears. If I
do the writeoutput outside of the for loop, then it works. I've checked
the size of the arrayLen just prior to the loop, and it reads the
expected value.
It's the strangest thing ... this was working. I don't believe I
changed anything. Then it stopped working.
