Andrew, Check out qForms: http://www.pengoworks.com/qforms/
Using the API will simply what you're trying to do greatly. One of the things that you'll be able to do is pass a JS-based structure (which you can get by using <cfwddx action="cfml2js">) to the setFields() method, which will allow you to populate existing values or default values with ease. -Dan > -----Original Message----- > From: Andrew Peterson [mailto:[EMAIL PROTECTED]] > Sent: Thursday, September 12, 2002 2:58 PM > To: CF-Talk > Subject: Validating form fields with a structure and loop > > Hi, > > I wanted a little more than the basic form field validation offered by > CFForm, and so I am validating form field data by placing error messages > in a structure called ErrorStruct and setting the form field name as the > key, so that later I can output it, like so: > > <!--- make sure field is numeric, etc. ---> > <cfif not IsNumeric(form.WithdrawPrincipal)> > <cfset StructInsert(ErrorStruct, "WithdrawPrincipal", "Withdrawl > Principal is not a number")> > </cfif> > > Then, later, reset the form field like so: > > <cfif structKeyExists(ErrorStruct,"WithdrawPrincipal")> > <cfset form.WithdrawPrincipal=""> > </cfif> > > And then of course in the form, the default value is like so: > > <input type="text" name="withdrawPrincipal" > value="#form.WithdrawPrincipal#"> > > Since I've got a lot of fields to validate, I'm trying to loop over the > structure keys and reset values that way, thus simplifying my code.
