Boolean

Boolean represents either Yes or No. Boolean will accept synonyms such as True and False, and 1 and 0. Any non-zero number evaluates to Yes. If the form is valid, Boolean always returns either Yes or No — "" evaluates to No, so setting the Required attribute on a Boolean datatype is meaningless. The default format for the Boolean datatype is boolean (which generates a single checkbox), although other options are demonstrated below.

Two special attributes are available for Boolean:

• YesSynonyms
  Optional. A list of other words that may be used as synonyms for "Yes." For example: "accept,oui". These synonyms are only relevant where the field's format permits freeform data entry, e.g.:

  <cf_terrafield
    name="accept"
    caption="Do you accept the terms and conditions?"
    datatype="boolean"
    format="text"
  />

• NoSynonyms
  Optional. A list of other words that may be used as synonyms for "No." For example: "decline,non".
