Data Validation

One of the big benefits of using CFFORM over standard HTML forms is the built-in data validation that is available. Both the CFINPUT and CFTEXTINPUT tags have an attribute called VALIDATE that accepts any of the following values:

CreditCard

Validates the form field data using the mod10 algorithm. Credit-card numbers can be entered as a single number or with dashes or spaces. ColdFusion automatically strips dashes and spaces before validating.

Date

Requires the form-field value to be in the U.S. date format mm/dd/yyyy.

EuroDate

Requires the form-field value to be in the European date format dd/mm/yyyy.

Float

Requires the form-field value to be a floating-point number.

Integer

Requires the form-field value to be an integer.

Social_Security_Number

Requires the form-field value to be a U.S. social security number in the format xxx-xx-xxxx or xxx xx xxxx.

Telephone

Requires the form-field value to be a U.S. telephone number formatted either xxx-xxx-xxxx or xxx xxx xxxx. The area code and exchange are required to begin with a number in the range of 1-9.

Time

Requires that the form-field value be entered as a valid time using the format hh:mm:ss.

ZipCode

Requires that the form-field value be entered as either a five- or nine-digit U.S. ZIP code using the format xxxxx, xxxxx-xxxx, or xxxxx xxxx.
