Detailed Description

The field under validation must only contain digits with a length between min and max. The digits are not interpreteded as a numeric value but as a string, so the min and max values are not a range for a numeric value but for the string length.

Note
Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. If the field's value is empty or if the field is missing in the input data, the validation will succeed without performing the validation itself. Use one of the required validators to require the field to be present and not empty.

Constructor & Destructor Documentation

ValidatorDigitsBetween::ValidatorDigitsBetween ( const QString &  field,
const QVariant &  min,
const QVariant &  max,
const ValidatorMessages messages = ValidatorMessages(),
const QString &  defValKey = QString() 
)
Parameters
fieldName of the input field to validate.
minMinimum length of the digits. Should either be an integer value to directly specify the length or the name of a Stash key containing the length constraint.
maxMaximum length of the digits. Should either be an integer value to directly specify the length or the name of a Stash key containing the length constraint.
messagesCustom error messages if validation fails.
defValKeyStash key containing a default value if input field is empty. This value will NOT be validated.
