Constructor & Destructor Documentation

◆ __construct()

ApiOptionsBase::__construct ( ApiMain $main,
$action,
UserOptionsManager $userOptionsManager,
PreferencesFactory $preferencesFactory )

Member Function Documentation

◆ commitChanges()

ApiOptionsBase::commitChanges ( )
abstractprotected

Applies changes to user preferences.

Reimplemented in ApiOptions.

Referenced by execute().

◆ execute()

◆ getAllowedParams()

ApiOptionsBase::getAllowedParams ( )

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

◆ getHtmlForm()

ApiOptionsBase::getHtmlForm ( )
protected

Get the HTMLForm for the user's preferences.

Returns
HTMLForm

Definition at line 181 of file ApiOptionsBase.php.

◆ getPreferences()

ApiOptionsBase::getPreferences ( )
protected

Returns preferences form descriptor.

Returns
mixed[][]

◆ getPreferencesFactory()

ApiOptionsBase::getPreferencesFactory ( )

◆ getPrefsKinds()

ApiOptionsBase::getPrefsKinds ( )
protected

Get the preference kinds for the current user's options.

This can only be called after $this->prefsKinds is set in execute()

Returns
string[]

Definition at line 172 of file ApiOptionsBase.php.

◆ getUserForUpdates()

ApiOptionsBase::getUserForUpdates ( )
protected

Load the user from the primary to reduce CAS errors on double post (T95839) Will throw if the user is anonymous.

Returns
User

Definition at line 270 of file ApiOptionsBase.php.

Referenced by ApiOptions\commitChanges(), ApiOptions\resetPreferences(), ApiOptions\setPreference(), and ApiOptions\shouldIgnoreKey().

◆ getUserForUpdatesOrNull()

ApiOptionsBase::getUserForUpdatesOrNull ( )
protected

Get the user for updates, or null if the user is anonymous.

Returns
User|null

Definition at line 280 of file ApiOptionsBase.php.

Referenced by execute().

◆ getUserOptionsManager()

ApiOptionsBase::getUserOptionsManager ( )
protected

◆ isWriteMode()

ApiOptionsBase::isWriteMode ( )

Indicates whether this module requires write mode.

This should return true for modules that may require synchronous database writes. Modules that do not need such writes should also not rely on primary database access, since only read queries are needed and each primary DB is a single point of failure. Additionally, requests that only need replica DBs can be efficiently routed to any datacenter via the Promise-Non-Write-API-Action header.

Stability: stable
to override
Returns
bool

Reimplemented from ApiBase.

Definition at line 334 of file ApiOptionsBase.php.

◆ mustBePosted()

ApiOptionsBase::mustBePosted ( )

Indicates whether this module must be called with a POST request.

Stability: stable
to override
Returns
bool

Reimplemented from ApiBase.

Definition at line 330 of file ApiOptionsBase.php.

◆ needsToken()

ApiOptionsBase::needsToken ( )

Returns the token type this module requires in order to execute.

Modules are strongly encouraged to use the core 'csrf' type unless they have specialized security needs. If the token type is not one of the core types, you must use the ApiQueryTokensRegisterTypes hook to register it.

Returning a non-falsey value here will force the addition of an appropriate 'token' parameter in self::getFinalParams(). Also, self::mustBePosted() must return true when tokens are used.

In previous versions of MediaWiki, true was a valid return value. Returning true will generate errors indicating that the API module needs updating.

Stability: stable
to override
Returns
string|false

Reimplemented from ApiBase.

Definition at line 361 of file ApiOptionsBase.php.
