Form Validation
Working with HTML Forms
You can apply validation rules to text or calendar field types.
Validation rules ensure that the information entered by site visitors
meets your criteria. For example, a validation rule specifies that a
response to the Telephone field is 10 digits. If the response does
not conform, an error message indicates the problem. The input
must conform before the form can be submitted.
For a list of validation rule types, see ”Validation Options” on
page 596.
When Validation Rules are Applied
TIP!
Form Fields
Validation rules are applied when a site visitor submits an entire
form, not when the input is entered. If an invalid response is found,
the error message that you define appears.
The site visitor must change his response to conform to the
validation rule. When he does, the next field is checked and, if that
is invalid, its error message appears, etc.
If you apply validation rules to more than one field, include the field name in the
error message. For example, enter The name field only allows text.
This is good practice because error messages only appear after a form is
submitted. If the message does not identify the field, the user may not know which
field needs correction.
You can insert the following types of fields onto an HTML form.
• ”Inserting a Checkbox Field” on page 591
• ”Inserting a Text Field” on page 592
• ”Inserting a Choices Field” on page 605
• ”Inserting a Calendar Field” on page 609
