Input Validation with CFFORM Controls

The CFINPUT and CFTEXTINPUT tags include the VALIDATE attribute, 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 and submits form data only on a successful match. A true value is returned on successful form submission, false if validation fails.
