Detailed Description

Parent class for all special pages.

Includes some static functions for handling the special page list deprecated in favor of SpecialPageFactory.

Stability: stable: to extend

Definition at line 45 of file SpecialPage.php.

Constructor & Destructor Documentation

◆ __construct()

SpecialPage::__construct	(	$name = `''`,
		$restriction = `''`,
		$listed = `true`,
		$function = `false`,
		$file = `''`,
		$includable = `false`
	)

Default constructor for special pages Derivative classes should call this from their constructor Note that if the user does not have the required level, an error message will be displayed by the default execute() method, without the global function ever being called.

If you override execute(), you can recover the default behavior with userCanExecute() and displayRestrictionError()

Stability: stable: to call

Parameters

string	$name	Name of the special page, as seen in links and URLs
string	$restriction	User right required, e.g. "block" or "delete"
bool	$listed	Whether the page is listed in Special:Specialpages
callable \| bool	$function	Unused
string	$file	Unused
bool	$includable	Whether the page can be included in normal pages

Definition at line 190 of file SpecialPage.php.

Member Function Documentation

◆ addFeedLinks()

SpecialPage::addFeedLinks ( $params )

protected

Adds RSS/atom links.

Parameters

array $params

Definition at line 1002 of file SpecialPage.php.

References wfAppendQuery(), and wfScript().

Referenced by MediaWiki\Specials\SpecialContributions\execute(), and SpecialWatchlist\outputFeedLinks().

◆ addHelpLink()

SpecialPage::addHelpLink	(	$to,
		$overrideBaseUrl = `false`
	)

Adds help link with an icon via page indicators.

Link target can be overridden by a local message containing a wikilink: the message key is: lowercase special page name + '-helppage'.

Parameters

string	$to	Target MediaWiki.org page title or encoded URL.
bool	$overrideBaseUrl	Whether $url is a full URL, to avoid MW.o.

Since: 1.25

Definition at line 1020 of file SpecialPage.php.

References $title.

◆ afterExecute()

SpecialPage::afterExecute ( $subPage )

protected

Gets called after.

See also: SpecialPage::execute.

Stability: stable: to override

Since: 1.20

Parameters

string | null $subPage

Definition at line 729 of file SpecialPage.php.

◆ beforeExecute()

SpecialPage::beforeExecute ( $subPage )

protected

Gets called before.

See also: SpecialPage::execute. Return false to prevent calling execute() (since 1.27+).

Stability: stable: to override

Since: 1.20

Parameters

string | null $subPage

Returns: bool|void

Reimplemented in SpecialUserLogin, LoginSignupSpecialPage, and AuthManagerSpecialPage.

	)

protected

Generate (prev x| next x) (20|50|100...) type links for paging.

Parameters

int	$offset
int	$limit
array	$query	Optional URL query parameter string
bool	$atend	Optional param for specified if this is the last page
string \| false	$subpage	Optional param for specifying subpage

Returns: string

Definition at line 1127 of file SpecialPage.php.

◆ checkLoginSecurityLevel()

SpecialPage::checkLoginSecurityLevel ( $level = null )

protected

Verifies that the user meets the security level, possibly reauthenticating them in the process.

This should be used when the page does something security-sensitive and needs extra defense against a stolen account (e.g. a reauthentication). The authentication framework will make an extra effort to make sure the user account is not compromised. What that exactly means will depend on the system and user settings; e.g. the user might be required to log in again unless their last login happened recently, or they might be given a second-factor challenge.

Calling this method will result in one if these actions:

return true: all good.
return false and set a redirect: caller should abort; the redirect will take the user to the login page for reauthentication, and back.
throw an exception if there is no way for the user to meet the requirements without using a different access method (e.g. this functionality is only available from a specific IP).

Note that this does not in any way check that the user is authorized to use this special page (use checkPermissions() for that).

Parameters

string | null $level A security level. Can be an arbitrary string, defaults to the page name.

Returns: bool False means a redirect to the reauthentication page has been set and processing of the special page should be aborted.

Exceptions

ErrorPageError If the security level cannot be met, even with reauthentication.
