Setting a variable name with a variable in a loop

[DAYohn]

Here is the code that bombs: <cfloop index='x' from='1' to='10' step='1'>
<cfif #evaluate('form.totalhours#x#')# eq 'r'> <cfset total_hours_#x# =
#evaluate('form.remaining_#x#')#> <cfelse> <cfset total_hours_#x# =
#evaluate('form.totalhours#x#')#> </cfif> </cfloop> I want to loop through
and create up to 10 variables named total_hours_1 through total_hours_10. Then
assign a value to them. The assigning of the value works, but the creating the
variable names does not work. How do I work around this? (Of note, the
variable name is used as the value of a db insert.)

change <cfset total_hours_#x# = #evaluate("form.remaining_#x#")#> to:

<cfset foo = evaluate("total_hours_#x# = form.remaining_#x#")>

The foo is useless, your variable "total_hours_#x#" will be setup.

First off, you don't need most of those pound signs. Step="1" is default in
cfloop, so don't really need that either.

<cfloop index='x' from='1' to='10'>
<cfset SetVariable("total_hours_" & x, IIf(Evaluate("form.totalhours" & x)
EQ "r",'Evaluate("form.remaining_" & x)','Evaluate("form.totalhours_" &
x)'))>
</cfloop>

SetVariable() is what you are looking for. And I used an Immediate If
statement instead of the cfif/cfelse tags.

You can also do it this way without using Evaluate(). There is more overhead
in using evaluate.



<cfloop index="x" from="1" to="10">
<cfif "form.totalhours#x#" eq "r">
<cfset "total_hours_#x#" = form["remaining_#x#"]>
<cfelse>
<cfset "total_hours_#x#" = form["totalhours#x#"]>
</cfif>
</cfloop>

I discovered this works... <cfloop index='x' from='1' to='10' step='1'>
<cfif #evaluate('form.totalhours#x#')# eq 'r'> <cfif
#evaluate('form.remaining_#x#')# eq ''> <cfparam name='total_hours_#x#'
default='#evaluate('form.remaining_#x#')#'> <cfelse> <cfparam
name='total_hours_#x#' default='#evaluate('form.totalhours#x#')#'>
</cfif> </cfloop> Thanks for all of the input. Alex
