Detailed Description

Type definition for checkbox-like boolean types.

This boolean is considered true if the parameter is present in the request, regardless of value. The only way for it to be false is for the parameter to be omitted entirely.

The result from validate() is a PHP boolean.

Member Function Documentation

◆ checkSettings()

Wikimedia\ParamValidator\TypeDef\PresenceBooleanDef::checkSettings ( string  $name,
  $settings,
array  $options,
array  $ret 
)

Validate a parameter settings array.

This is intended for validation of parameter settings during unit or integration testing, and should implement strict checks.

The rest of the code should generally be more permissive.

See also
ParamValidator::checkSettings()
Stability: stable
to override
Parameters
string$nameParameter name
array | mixed$settingsDefault value or an array of settings using PARAM_* constants.
array$optionsOptions array, passed through to the TypeDef and Callbacks.
array$ret
  • 'issues': (string[]) Errors detected in $settings, as English text. If the settings are valid, this will be the empty array. Keys on input are ParamValidator constants, allowing the typedef to easily override core validation; this need not be preserved when returned.
  • 'allowedKeys': (string[]) ParamValidator keys that are allowed in $settings.
  • 'messages': (MessageValue[]) Messages to be checked for existence.
Returns
array $ret, with any relevant changes.

◆ getHelpInfo()

Wikimedia\ParamValidator\TypeDef\PresenceBooleanDef::getHelpInfo (   $name,
array  $settings,
array  $options 
)

Describe parameter settings in human-readable format.

Keys in the returned array should generally correspond to PARAM constants.

If relevant, a MessageValue describing the type itself should be returned with key ParamValidator::PARAM_TYPE.

The default messages for other ParamValidator-defined PARAM constants may be suppressed by returning null as the value for those constants, or replaced by returning a replacement MessageValue. Normally, however, the default messages should not be changed.

MessageValues describing any other constraints applied via PARAM constants specific to this class should also be returned.

Parameters
string$nameParameter name being described.
array$settingsParameter settings array.
array$optionsOptions array.
Returns
(MessageValue|null)[]

◆ getParamInfo()

Wikimedia\ParamValidator\TypeDef\PresenceBooleanDef::getParamInfo (   $name,
array  $settings,
array  $options 
)

Describe parameter settings in a machine-readable format.

Keys should be short strings using lowercase ASCII letters. Values should generally be values that could be encoded in JSON or the like.

This is intended to handle PARAM constants specific to this class. It generally shouldn't handle constants defined on ParamValidator itself.

Stability: stable
to override
Parameters
string$nameParameter name.
array$settingsParameter settings array.
array$optionsOptions array.
Returns
array

◆ getValue()

Wikimedia\ParamValidator\TypeDef\PresenceBooleanDef::getValue (   $name,
array  $settings,
array  $options 
)

Get the value from the request.

Stability: stable
to override
Note
Only override this if you need to use something other than $this->callbacks->getValue() to fetch the value. Reformatting from a string should typically be done by self::validate().
Handling of ParamValidator::PARAM_DEFAULT should be left to ParamValidator, as should PARAM_REQUIRED and the like.
Parameters
string$nameParameter name being fetched.
array$settingsParameter settings array.
array$optionsOptions array.
Returns
null|mixed Return null if the value wasn't present, otherwise a value to be passed to self::validate().

◆ normalizeSettings()

Wikimedia\ParamValidator\TypeDef\PresenceBooleanDef::normalizeSettings ( array  $settings)

Normalize a settings array.

Stability: stable
to override
Parameters
array$settings
Returns
array

◆ validate()

Wikimedia\ParamValidator\TypeDef\PresenceBooleanDef::validate (   $name,
  $value,
array  $settings,
array  $options 
)

Validate the value.

When ParamValidator is processing a multi-valued parameter, this will be called once for each of the supplied values. Which may mean zero calls.

When getValue() returned null, this will not be called.

Parameters
string$nameParameter name being validated.
mixed$valueValue to validate, from getValue().
array$settingsParameter settings array.
array$optionsOptions array. Note the following values that may be set by ParamValidator:
  • is-default: (bool) If present and true, the value was taken from PARAM_DEFAULT rather that being supplied by the client.
  • values-list: (string[]) If defined, values of a multi-valued parameter are being processed (and this array holds the full set of values).
Returns
mixed Validated value
Exceptions
ValidationExceptionif the value is invalid
