Detailed Description

The field under validation must have the same content as otherField.

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.

Example

void MyController::do_form(Context *c)
{
    Validator v({new ValidatorSame(QStringLiteral("field"),
                                   QStringLiteral("other_field"),
                                   QT_TRANSLATE_NOOP("MyController", "Other Field"),
                                   ValidatorMessages(QT_TRANSLATE_NOOP("MyController",
                                                                       "Field")))
                }, QLatin1String("MyController"));
}

Return type

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

Constructor & Destructor Documentation

ValidatorSame()

ValidatorSame::ValidatorSame	(	const QString &	field,
		const QString &	otherField,
		const char *	otherLabel = nullptr,
		const ValidatorMessages &	messages = ValidatorMessages(),
		const QString &	defValKey = QString()
	)

Constructs a new ValidatorSame object with the given parameters.

Parameters

field	Name of the input field to validate.
otherField	Name of the other field that must have the same input.
otherLabel	Human readable other field label, used for generic error messages.
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.

Definition at line 10 of file validatorsame.cpp.

~ValidatorSame()

ValidatorSame::~ValidatorSame ( )

overridedefault

Destroys the ValidatorSame object.

Member Function Documentation

genericValidationError()

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

overrideprotectedvirtual

Returns a generic error message if validation failed.

Reimplemented from Cutelyst::ValidatorRule.

Definition at line 47 of file validatorsame.cpp.

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

validate()

ValidatorReturnType ValidatorSame::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.
