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.


Input Validation Controls
VALIDATE Entry	Description
Date	Verifies US date entry in the form mm/dd/yyy.
Eurodate	Verifies valid European date entry in the form dd/mm/yyyy.
Time	Verifies a time entry in the form hh:mm:ss.
Float	Verifies a floating point entry.
Integer	Verifies an integer entry.
Telephone	Verifies a telephone entry. Telephone data must be entered as ###-###-####. The hyphen separator (-) can be replaced with a blank. The area code and exchange must begin with a digit between 1 and 9.
Zipcode	(U.S. formats only) Number can be a 5-digit or 9-digit zip in the form #####-####. The hyphen separator (-) can be replaced with a blank.
Creditcard	Blanks and dashes are stripped and the number is verified using the mod10 algorithm.
Social_security_number	Number must be entered as ###-##-####. The hyphen separator (-) can be replaced with a blank.

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.
