Detailed Description

The field under validation is only allowed to contain alphabetic characters. If asciiOnly is set to true, only US-ASCII characters are allowed, otherwise all UTF-8 alpha-numeric characters are allowed.

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.

Examples: "Hallo Kuddel!" // invalid

"HalloKöddel" // valid if asciiOnly is false, otherwise it is false

"HalloKuddel" // valid if asciiOnly is true

" " // valid if trimBefore is true, invalid if trimBefore is false

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

Constructor & Destructor Documentation

◆ ValidatorAlpha()

ValidatorAlpha::ValidatorAlpha	(	const QString &	field,
		bool	asciiOnly = `false`,
		const ValidatorMessages &	messages = `ValidatorMessages()`,
		const QString &	defValKey = `QString()`
	)

Constructs a new ValidatorAlpha object with the given parameters.

Parameters

field	Name of the input field to validate.
asciiOnly	If `true`, only ASCII characters are allowed.
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 12 of file validatoralpha.cpp.

◆ ~ValidatorAlpha()

ValidatorAlpha::~ValidatorAlpha ( )

overridedefault

Destroys the ValidatorAlpha object.

Member Function Documentation

◆ genericValidationError()

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

overrideprotectedvirtual

Returns a generic error message if validation failed.

Reimplemented from Cutelyst::ValidatorRule.

◆ validate()

ValidatorReturnType ValidatorAlpha::validate	(	Cutelyst::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.
