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,
Douglas Malcolm

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
