Repost/Edit: apparently msoft forefront exchange server thinks I was being
profane.
You don't need evaluate for dynamically created form variables, in almost
all cases the struct syntax #form['type'&idx]# will suffice and is more
efficient. For this particular scenario, evaluate is an unnecessary overhead
and should be avoided.
<cfquery datasource="#request.datasource#">
<cfloop from="1" to="#rows#" index="idx">
INSERT INTO tbl_ballotOrder (
type,
number,
issue
) VALUES (
<cfqueryparam value="#form['type'&idx]#"
cfsqltype="cf_sql_varchar" />,
<cfqueryparam value="#form['number'&idx]#"
cfsqltype="cf_sql_integer" />,
<cfqueryparam value="#form['issue'&idx]#"
cfsqltype="cf_sql_varchar" />
)
</cfloop>
</cfquery>
May I also point out the use of CFQUERYPARAM. It's basic principles; unless
you've got a *very* fine reason not to, always use cfqueryparam. Protect
yourself from SQL injection attacks, make your life easier.
No offence intended, but Will I urge you to ignore the 'evaluate' based
advice.
Cheers,
Gabriel

I agree with NK pay attention to the evaluate function. It works like a
charm for dynamically created form variables. I use it often. :)
