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")))
}, u"MyController"_s);
}
The Cutelyst Context.
Definition context.h:42
ValidatorSame(const QString &field, const QString &otherField, const char *otherLabel=nullptr, const ValidatorMessages &messages=ValidatorMessages(), const QString &defValKey={})
Stores custom error messages and the input field label.
Return type
On success, ValidatorReturnType::value will contain a QString.

Validator for general usage of validators.

Constructor & Destructor Documentation

◆ ValidatorSame()

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

Constructs a new ValidatorSame object with the given parameters.

Parameters
fieldName of the input field to validate.
otherFieldName of the other field that must have the same input.
otherLabelHuman readable other field label, used for generic error messages.
messagesCustom error messages if validation fails.
defValKeyStash key containing a default value if input field is empty. This value will NOT be validated.

◆ genericValidationError()

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

const ParamsMultiMap & params ) const
overrideprotectedvirtual

◆ validateCb()

void ValidatorSame::validateCb ( Context * c,
const ParamsMultiMap & params,
ValidatorRtFn cb ) const
overrideprotectedvirtual

Performs the validation on the input params and calls the cb with the ValidatorReturnType as argument.

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