Steven,
This may help. I pasted it from a presentation I wrote to give to some
staff programmers recently, so please excuse the semi-formal language.

Form validation via cold fusion
CF includes an easy way to validate your forms, called "Cold Fusion
embedded
form validation". The syntax is passed to the cf server via a
normal-looking <input type=hidden> scheme.
Suppose you have a field called Lastname. It is in your form thus:
<input type="text" name="Lastname" size="20" maxlength="50">
To make this field required, add the following hidden field:
<input type="hidden" name="Lastname_required" value="Enter your
last name."
>
This tells the cf engine that the field Lastname is required, and if a form
is submitted without that field, the error message "Enter your last name."
shows on the screen.
There are many validation checks at your disposal. The list includes:
_date : Checks for a date in the most common formats
_float : Numeric data, decimal point allowed
_integer : Numeric data, no decimal point allowed
_range : Range of values, as in "min=5 max=10"
_required : Field may not be left blank
_time : Time in most common formats
There is no limit to the number of validation rules you can embed in a
form.
Every rule must be embedded as a separate Hidden field, however. So to
flag
a field as both numeric and required, for example, you'd need 2 hidden
fields.

Hope that helps,

Subject: Simple validation
I am in desperate need of a simple validation of two types of form fields.
1. Date field (not a cfform just a plain form) - must validate that data
entered is a date
2. Number field (not a cfform just a plain form) - must validate that data
entered is a number
Thanks
Stephanie
