Note that the regular expression used here includes beginning and ending delimiters (in this case the /

character), and ensures that the whole string matches by the start-of-string marker ^ and the end-of-string

marker $. The construct \d is used to match a single digit. Many equivalent regular expressions could be

written to perform this validation task. See “Regular Expressions” in the Reference chapter for more

information about regular expressions.

Advanced Form Field Properties

The Advanced Properties control certain optional form processing behaviors. You can also specify

JavaScript expressions to build dynamic forms similar to those found elsewhere in the application.

On the Customize Form Fields page, select the Show advanced properties check box to display the

advanced properties in the form field editor.

The Conversion, Value Format, and Display Function options can be used to enable certain form

processing behavior. See “Form Field Conversion Functions” and “Form Field Display Formatting

Functions”.

In the Force Value row, use the Always use initial value on form submit check box to prevent attempts

to override the value set for a field. When this option is set, if a user modifies the field’s value, it reverts to

the specified initial value when the form is submitted. A similar effect can be achieved by using appropriate

validation rules, but selecting this check box is easier. Using this option is recommended for hidden fields,

particularly those related to security, such as role ID or expiration date.
