Member Function Documentation

◆ centralIdFromLocalUser()

CentralIdLookup::centralIdFromLocalUser	(	User	$user,
			$audience = `self::AUDIENCE_PUBLIC`,
			$flags = `self::READ_NORMAL`
	)

Given a local User object, return the central ID.

Note: Unlike centralIdFromName(), this does guarantee that the local user is attached to the central account.

Parameters

User	$user	Local user
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: int User ID; 0 if the local user does not correspond to a central user, $audience lacks the rights needed to see it, or the central user isn't locally attached.

Definition at line 256 of file CentralIdLookup.php.

References centralIdFromName(), User\getName(), and isAttached().

◆ centralIdFromName()

CentralIdLookup::centralIdFromName	(	$name,
		$audience = `self::AUDIENCE_PUBLIC`,
		$flags = `self::READ_NORMAL`
	)

Given a (local) user name, return the central ID.

Note: There's no requirement that the user name actually exists locally, or if it does that it's actually attached to the central account.

Parameters

string	$name	Canonicalized user name
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: int User ID; 0 if the name does not correspond to a user or $audience lacks the rights needed to see it.

◆ centralIdsFromNames()

CentralIdLookup::centralIdsFromNames	(	array	$names,
			$audience = `self::AUDIENCE_PUBLIC`,
			$flags = `self::READ_NORMAL`
	)

Given an array of (local) user names, return the central IDs.

Parameters

string[]	$names	Canonicalized user names
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: int[] User IDs

◆ checkAudience()

CentralIdLookup::checkAudience ( $audience )

protected

Parameters

int | User $audience One of the audience constants, or a specific user

Returns: User|null User to check against, or null if no checks are needed

◆ isAttached()

CentralIdLookup::isAttached	(	User	$user,
			$wikiId = `null`
	)

abstract

Check that a User is attached on the specified wiki.

If unattached local accounts don't exist in your extension, this comes down to a check whether the central account exists at all and that $wikiId is using the same central database.

Parameters

User	$user
string \| null	$wikiId	Wiki to check attachment status. If null, check the current wiki.

Returns: bool

◆ localUserFromCentralId()

CentralIdLookup::localUserFromCentralId	(	$id,
		$audience = `self::AUDIENCE_PUBLIC`,
		$flags = `self::READ_NORMAL`
	)

Given a central user ID, return a local User object.

Note: Unlike nameFromCentralId(), this does guarantee that the local user exists and is attached to the central account.

Parameters

int	$id	Central user ID
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: User|null Local user, or null if: $id doesn't correspond to a user, $audience lacks the rights needed to see the user, the user doesn't exist locally, or the user isn't locally attached.
