Once you use ArrayDeleteAt, the array is reindexed
try this :-)
<cfset idlist = "1,2,3" />
<cfset idlistsorted = ListSort(idlist) />
<cfloop from=1 to=ArrayLen(myarray) index=i >
<cfset IDtoDelete = ListGetAt(idlistsorted ,i) - i />
<cfset ArrayDeleteAt[IDtoDelete] />
</cfloop>

Subject: Arrays -Deleting specific items
I have an array and need to delete specific positions by using a list of
positions to delete.
Array contains 8 items and I need to delete the items at positions
"2,3,4,5,6".
I've been using the code below and it works most of the time if I delete one
at time but
once I try to delete multiple items it errors out. I'm obviously overlooking
something and
extra eyes would be great!
<CFSCRIPT>
INDEX_TO_DELETE = LISTSORT(form.INDEX_TO_DELETE,"NUMERIC","DESC");
FOR (INDEX=1;INDEX LTE ListLen(form.index_to_delete); INDEX=INDEX+1)
{
ArrayDeleteAt(session.aCart,ListGetAt(form.index_to_delete,index));
}
</CFSCRIPT>
Thanks,
Dave
