How do I display dynamically named fields?

[bushnellweb]

In my form I named the check boxes "chk_img_" & #i#.
So I get how to use it in IsDefined, but how do I get it to display the value of that FORM.check_img_1 without hard coding the number 1? Sometimes it might be like up to 1,000 and I'm not going to hard code a 1000000000 options. This is probabyl a very easy fix, but i've been up all night working on this code and now I'm dead in the water, with no brain power. Thanks in advance for the help.

<cfloop from="1" to="#intCheckBoxesCount#" index="i">
<cfif IsDefined("FORM.chk_img_" & #i#)>
<cfoutput>                    chk_img_#i# value = #FORM.check_img_#<!--- this is where i am having trouble --->
</cfoutput>
</cfif>
</cfloop>

You can use the form struct (if using POST):

form["chk_img_" & #i#]

thanks, haha I've used it before. I don't know what I was/wasn't thinking

Yes, it's easy to forget if not used often. Perhaps something to add to a "useful things easily forgotten" list :)

u cn cmbne text and vrble names to cnstrct a variable name on the left side of a cfset assgnmnt. e.g., d following code sets d value of d variable Product12 to the string "Widget":

<cfset ProdNo = 12>

<cfset "Product#ProdNo#" = "Widget">

To cnstrct a vrble name dis way, all the text on the left side of the equal sign must be in quotation marks.

dis usage is less efficient dan using arrays. The following example has the same purpose as the previous one, but requires less processing:

<cfset MyArray=ArrayNew(1)>

<cfset prodNo = 12>
<cfset myArray[prodNo] = "Widget">
