• Cfform offers 2 types of validation
• Client & server
• ColdFusion has extended HTML forms to give more power and ease of use
• ColdFusion form tags and subtags let you create dynamic forms in three formats
• Adds hidden form fields for server validation

• required = “yes”
• validate = “validation type”
• message = “error message”
• range =”min-value, max-value”

• ValidateAt attribute accepts three values
• onServer
• onSubmit

• Use one or more by separating these values with commas
• validateAt=”onServer, onSubmit”
• Requiring data using onSubmit

  <cfinput type="text" name="FIRSTNAME" size="20" maxlength="20" required="yes" message="Please input an Artist’s first name." validateat="onSubmit" id="FIRSTNAME">
