Question Getting values of dynamic form fields
I'm new to CF and need some advice.

I have a form that has dynamically created input boxes from a javascript function. They are named txtInput1, txtInput2 etc.

Could someone please tell me how I can use the following code correctly:

<cfif #form.noOfInputs# GTE "0">
<cfloop from="1" to="#form.noOfInputs#" index="i">
<cfoutput>
#i# : #form.txtInput[i]#</cfoutput>
</cfloop>
</cfif>

(note, noOfInputs is usually around 5)

The first #i# displays correctly but the #form.txtInput[i]# errors with

An error occurred while evaluating the expression:
#form.txtInput[i]#
Error near line 49, column 23.
--------------------------------------------------------------------------------
Error resolving parameter FORM.TXTINPUT

Can someone please tell me how I can dynamically call the form names?

Thank you
BatGrrrL

<cfif #form.noOfInputs# GTE "0">
<cfloop from="1" to="#form.noOfInputs#" index="i">
<cfoutput>
#i# : #evaluate( 'form.txtInput#i#' )#</cfoutput>
</cfloop>
</cfif>

should work if they are named 'txtInput1', 'txtInput2', etc.

Evaluate() is pretty hungry

Code:
<cfif form.noOfInputs> 
<cfloop from="1" to="#form.noOfInputs#" index="i"> 
<cfoutput> 
#i# : #form["txtInput#i#"]#</cfoutput> 
</cfloop> 
</cfif>


would be a better bet

I'm not convinced that having Javascript generate the names of your form fields is a good idea. People can turn off Javascript and this would break the whole application. Why not just let the server dynamically generate the form field names prior to returning the web page to the user?
