Input Validation with CFFORM Controls
The CFINPUT and CFTEXTINPUT tags include the VALIDATE attributes which allows
you to specify a valid data type entry for the control. You can validate user entries on
the following data types.
When you specify an input type in the VALIDATE attribute, ColdFusion tests for the
specified input type when the form is submitted and submits form data only on a
successful match. A true value is returned on successful form submission, false if
validation fails.
