Since: 1.20

Parameters

string | null $subPage

Returns: bool|void

Reimplemented from LoginSignupSpecialPage.

Definition at line 76 of file SpecialUserLogin.php.

◆ clearToken()

SpecialUserLogin::clearToken ( )

protected

Definition at line 143 of file SpecialUserLogin.php.

References AuthManagerSpecialPage\getRequest().

Referenced by successfulAction().

◆ doesWrites()

SpecialUserLogin::doesWrites ( )

Indicates whether this special page may perform database writes.

Returns: bool

Since: 1.27

Reimplemented from SpecialPage.

Definition at line 48 of file SpecialUserLogin.php.

◆ getDefaultAction()

SpecialUserLogin::getDefaultAction ( $subPage )

protected

Get the default action for this special page, if none is given via URL/POST data.

Subclasses should override this (or override loadAuth() so this is never called).

Parameters

string $subPage Subpage of the special page.

Returns: string an AuthManager::ACTION_* constant.

Reimplemented from AuthManagerSpecialPage.

Definition at line 56 of file SpecialUserLogin.php.

◆ getDescription()

SpecialUserLogin::getDescription ( )

Returns the name that goes in the \<h1\> in the special page itself, and also the name that will be listed in Special:Specialpages.

Derived classes can override this, but usually it is easier to keep the default behavior.

Returns: string

Reimplemented from SpecialPage.

Definition at line 60 of file SpecialUserLogin.php.

References SpecialPage\msg().

◆ getGroupName()

SpecialUserLogin::getGroupName ( )

protected

Under which header this special page is listed in Special:SpecialPages See messages 'specialpages-group-*' for valid names This method defaults to group 'other'.

Definition at line 151 of file SpecialUserLogin.php.

◆ getLoginSecurityLevel()

SpecialUserLogin::getLoginSecurityLevel ( )

protected

Tells if the special page does something security-sensitive and needs extra defense against a stolen account (e.g.

a reauthentication). What exactly that will mean is decided by the authentication framework.

Returns: bool|string False or the argument for AuthManager::securitySensitiveOperationStatus(). Typically a special page needing elevated security would return its name here.

Reimplemented from AuthManagerSpecialPage.

Definition at line 52 of file SpecialUserLogin.php.

◆ getToken()

SpecialUserLogin::getToken ( )

protected

Returns the CSRF token.

Returns: Token

Reimplemented from AuthManagerSpecialPage.

Returns the name of the CSRF token (under which it should be found in the POST or GET data).

Returns: string

◆ isSignup()

SpecialUserLogin::isSignup ( )

protected

Reimplemented from LoginSignupSpecialPage.

◆ logAuthResult()

SpecialUserLogin::logAuthResult	(		$success,
			$status = null )

protected

Logs to the authmanager-stats channel.

Parameters

bool	$success
string \| null	$status	Error message key

Reimplemented from LoginSignupSpecialPage.

Definition at line 155 of file SpecialUserLogin.php.

References $success.

◆ setHeaders()

SpecialUserLogin::setHeaders ( )

Sets headers - this should be called from the execute() method of all derived classes!

Reimplemented from SpecialPage.

Definition at line 64 of file SpecialUserLogin.php.

References SpecialPage\getOutput(), SpecialPage\getUser(), and SpecialPage\msg().

◆ successfulAction()

SpecialUserLogin::successfulAction	(		$direct = false,
			$extraMessages = null )

protected

Run any hooks registered for logins, then HTTP redirect to $this->mReturnTo (or Main Page if that's undefined).

Formerly we had a nice message here, but that's really not as useful as just being sent to wherever you logged in from. It should be clear that the action was successful, given the lack of error messages plus the appearance of your name in the upper right.

Parameters

bool	$direct	True if the action was successful just now; false if that happened pre-redirection (so this handler was called already)
StatusValue \| null	$extraMessages

Reimplemented from LoginSignupSpecialPage.
