 __construct (Callbacks $callbacks, TitleFactory $titleFactory)
 
 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 ( $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.

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

 
 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

 
 stringifyValue ( $name, $value, array $settings, array $options)
 Convert a value to a string representation.This is intended as the inverse of getValue() and validate(): this should accept anything returned by those methods or expected to be used as PARAM_DEFAULT, and if the string from this method is passed in as client input or PARAM_DEFAULT it should give equivalent output from validate().
Parameters
string$nameParameter name being converted.
mixed$valueParameter value being converted. Do not pass null.
array$settingsParameter settings array.
array$optionsOptions array.
Returns
string|null Return null if there is no representation of $value reasonably satisfying the description given.

 
 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

Detailed Description

Type definition for page titles.

Failure codes:

  • 'badtitle': invalid title (e.g. containing disallowed characters). No data.

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

Returns
string|LinkTarget Depending on the PARAM_RETURN_OBJECT setting.

Member Data Documentation

◆ PARAM_MUST_EXIST

const MediaWiki\ParamValidator\TypeDef\TitleDef::PARAM_MUST_EXIST = 'param-must-exist'

(bool) Whether the page with the given title needs to exist.

Defaults to false.

Definition at line 29 of file TitleDef.php.

◆ PARAM_RETURN_OBJECT

const MediaWiki\ParamValidator\TypeDef\TitleDef::PARAM_RETURN_OBJECT = 'param-return-object'

(bool) Whether to return a LinkTarget.

If false, the validated title is returned as a string (in getPrefixedText() format). Default is false.

Avoid setting true with PARAM_ISMULTI, as it may result in excessive DB lookups. If you do combine them, consider setting low values for PARAM_ISMULTI_LIMIT1 and PARAM_ISMULTI_LIMIT2 to mitigate it.
