Detailed Description

If the other field specified as otherField does not contain any of the values specified in the otherValues list, the field under validation must be present and not empty. This validator is the opposite of ValidatorRequiredIf.

Note

Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. So, fields that only contain whitespaces will be treated as empty.

Return type

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

ValidatorRequiredUnless()

ValidatorRequiredUnless::ValidatorRequiredUnless	(	const QString &	field,
		const QString &	otherField,
		const QStringList &	otherValues,
		const ValidatorMessages &	messages = ValidatorMessages()
	)

Parameters

field	Name of the input field to validate.
otherField	Name of the other input field to validate.
otherValues	List of values that are not allowed to be in the other field to require the main field.
messages	Custom error messages if validation fails.

Member Function Documentation

genericValidationError()

QString ValidatorRequiredUnless::genericValidationError ( Context *  c, const QVariant &  errorData = QVariant()  ) const

overrideprotectedvirtual

Returns a generic error message if validation failed.

Reimplemented from Cutelyst::ValidatorRule.

Definition at line 53 of file validatorrequiredunless.cpp.

References QString::arg(), QString::isEmpty(), Cutelyst::ValidatorRule::label(), and Cutelyst::Context::qtTrId().

validate()

ValidatorReturnType ValidatorRequiredUnless::validate ( Context *  c, const ParamsMultiMap &  params  ) const

overrideprotectedvirtual

Performs the validation on the input params and returns the result.

If validation succeeded, ValidatorReturnType::value will contain the input paramter value as QString.

Implements Cutelyst::ValidatorRule.
