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.
