Detailed Description

Redirect a user to the login page or account creation page.

This is essentially an ErrorPageError exception which by default uses the 'exception-nologin' as a title and 'exception-nologin-text' for the message.

When the user is a temporary account, the redirect will point to the Special:CreateAccount page unless specifically set not to. In all other cases, the redirect is to the Special:UserLogin page.

The message key for the reason will be modified to include '-for-temp-user' when the user is logged in to a temporary account and this message key exists (i.e. defined and not empty).

Note: In order for this exception to redirect, the error message passed to the constructor has to be explicitly added to LoginHelper::validErrorMessages or with the LoginFormValidErrorMessages hook. Otherwise, the user will just be shown the message rather than redirected.

Example:: if ( $user->isAnon() ) {

throw new UserNotLoggedIn();

}

MediaWiki\Exception\UserNotLoggedIn
Redirect a user to the login page or account creation page.
Definition UserNotLoggedIn.php:55

Note the parameter order differs from ErrorPageError, this allows you to simply specify a reason without overriding the default title.

Example:: if ( $user->isAnon() ) {

throw new UserNotLoggedIn( 'action-require-loggedin' );

}

You can use SpecialPage::requireLogin and SpecialPage::requireNamedUser to throw this exception when the user is an anon user or not named respectively.

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Exception\UserNotLoggedIn::__construct	(		$reasonMsg = 'exception-nologin-text',
			$titleMsg = 'exception-nologin',
			$params = [],
		bool	$alwaysRedirectToLoginPage = false )

Stability: stable: to call

Note: The value of the $reasonMsg parameter must be set with the LoginFormValidErrorMessages hook if you want the user to be automatically redirected to the login form.

Parameters

string	$reasonMsg	A message key containing the reason for the error. '-for-temp-user' will be appended to the end of the message key if the user is a temporary account and the redirect is to the Special:CreateAccount page. The modification is skipped if the message key does not exist. Optional, default: 'exception-nologin-text'
string	$titleMsg	A message key to set the page title. Optional, default: 'exception-nologin'
array	$params	Parameters to wfMessage() for $reasonMsg and $tempUserReasonMsg Optional, default: []
bool	$alwaysRedirectToLoginPage	Whether we should always redirect to the login page, even if the user is a temporary account. If false (the default), the redirect will be to Special:CreateAccount when the user is logged in to a temporary account.
