Input Validation with cfform Controls
The cfinput and cftextinput tags include the validate attributes which allows you
to specify a valid data entry type 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 you submit the form, and submits form data only on a
successful match. A successful form submission returns the value True and returns
the value False if validation fails.
