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.

Return type: On success, ValidatorReturnType::value will contain a QString.

Constructor & Destructor Documentation

◆ ValidatorDigitsBetween()

ValidatorDigitsBetween::ValidatorDigitsBetween	(	const QString &	field,
		const QVariant &	min,
		const QVariant &	max,
		const ValidatorMessages &	messages = ValidatorMessages(),
		const QString &	defValKey = QString() )

Constructs a new ValidatorDigitsBetween with the given parameters.

Parameters

field	Name of the input field to validate.
min	Minimum 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.
max	Maximum 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.
messages	Custom error messages if validation fails.
defValKey	Stash key containing a default value if input field is empty. This value will NOT be validated.
