Interfaces

ActionInterface
Interface for all action classes.
Routable
Classes implementing this interface can build routes from URL query parameters and parse routes back into URL query parameters.

Properties

$subaction  : string
$subactions  : array<string|int, mixed>
$obj  : static

Methods

buildRoute()  : array<string|int, mixed>
Builds a routing path based on URL query parameters.
call()  : void
Convenience method to load() and execute() an instance of this class.
canBeLogged()  : bool
Determines whether this action can be logged in the online log.
canShowDebuggingInfo()  : bool
Determines whether debugging info should be shown.
canShowInMaintenanceMode()  : bool
Determines whether this action allows access in maintenance mode.
execute()  : void
Dispatcher to whichever sub-action method is necessary.
getOutputType()  : OutputTypeInterface
Gets the output type for this action.
index()  : mixed
The main page for the Help section
isAgreementAction()  : bool
Determines whether this action can be accessed without accepting the registration agreement and privacy policy.
isRestrictedGuestAccessAllowed()  : bool
Determines whether this action allows access if guest access is disabled.
isSimpleAction()  : bool
Determines whether this is a simple action.
load()  : static
Static wrapper for constructor.
parseRoute()  : array<string|int, mixed>
Parses a route to get URL query parameters.
subActionProvider()  : null|array<string|int, mixed>
Called by Subs-Compat.php BackwardCompatibility wrapper functions to provide subaction execution for existing mods
__construct()  : mixed
Constructor. Protected to force instantiation via self::load().
buildActionRoute()  : array<string|int, mixed>
Builds a routing path for an action based on URL query parameters.
parseActionRoute()  : array<string|int, mixed>
Parses a route for an action to get URL query parameters.

Properties

$subaction

public string $subaction = 'index'

The requested sub-action. This should be set by the constructor.

$subactions

public static array<string|int, mixed> $subactions = ['index' => 'index']

Available sub-actions.

$obj

protected static static $obj

An instance of this class. This is used by the load() method to prevent multiple instantiations.

Methods

buildRoute()

Builds a routing path based on URL query parameters.

public static buildRoute(array<string|int, mixed> $params) : array<string|int, mixed>
Parameters
$params : array<string|int, mixed>

URL query parameters.

Return values
array<string|int, mixed> —

Contains two elements: ['route' => [], 'params' => []]. The 'route' element contains the routing path. The 'params' element contains any $params that weren't incorporated into the route.

call()

Convenience method to load() and execute() an instance of this class.

public static call() : void

canBeLogged()

Determines whether this action can be logged in the online log.

public canBeLogged() : bool
Return values
bool

canShowDebuggingInfo()

Determines whether debugging info should be shown.

public canShowDebuggingInfo() : bool
Return values
bool

canShowInMaintenanceMode()

Determines whether this action allows access in maintenance mode.

public canShowInMaintenanceMode() : bool
Return values
bool —

True if access is allowed, false otherwise.

execute()

Dispatcher to whichever sub-action method is necessary.

public execute() : void

index()

The main page for the Help section

public index() : mixed

isAgreementAction()

Determines whether this action can be accessed without accepting the registration agreement and privacy policy.

public isAgreementAction() : bool
Return values
bool

isRestrictedGuestAccessAllowed()

Determines whether this action allows access if guest access is disabled.

public isRestrictedGuestAccessAllowed() : bool
Return values
bool —

True if access is allowed, false otherwise.

isSimpleAction()

Determines whether this is a simple action.

public isSimpleAction() : bool
Return values
bool

load()

Static wrapper for constructor.

public static load() : static
Return values
static —

An instance of this class.

parseRoute()

Parses a route to get URL query parameters.

public static parseRoute(array<string|int, mixed> $route[, array<string|int, mixed> $params = [] ]) : array<string|int, mixed>
Parameters
$route : array<string|int, mixed>

Array of routing path components.

$params : array<string|int, mixed> = []

Any existing URL query parameters.

Return values
array<string|int, mixed> —

URL query parameters

subActionProvider()

Called by Subs-Compat.php BackwardCompatibility wrapper functions to provide subaction execution for existing mods

public static subActionProvider([null|string $sa = null ][, bool $return_config = false ][, string|null $activity = null ]) : null|array<string|int, mixed>
Parameters
$sa : null|string = null
$return_config : bool = false
$activity : string|null = null
Return values
null|array<string|int, mixed>

__construct()

Constructor. Protected to force instantiation via self::load().

protected __construct() : mixed

Redirect to the user help ;). It loads information needed for the help section. It is accessed by ?action=help.

Uses Help template and Manual language file.

buildActionRoute()

Builds a routing path for an action based on URL query parameters.

protected static buildActionRoute(array<string|int, mixed> &$params) : array<string|int, mixed>

The 'action', 'area', and 'sa' parameters will be mapped to route path components in that order. The 'action' parameter is required, whereas 'area' and 'sa' are optional and will be silently skipped if not set.

The parameters are passed by reference and parameters are removed from the array when recognized. This lets wrapper methods continue parsing the remainder of the parameters without worrying about duplicate elements.

Parameters
$params : array<string|int, mixed>

URL query parameters.

Return values
array<string|int, mixed> —

The route path elements.

parseActionRoute()

Parses a route for an action to get URL query parameters.

protected static parseActionRoute(array<string|int, mixed> &$route) : array<string|int, mixed>

The first element of the route path is mapped to the 'action' parameter.

For the 'admin', 'moderate', and 'profile' actions, the second element of the route is mapped to the 'area' parameter and the third element is mapped to the 'sa' parameter.

For all other actions, the second element of the route path is mapped to the 'sa' parameter.

The route passed by reference and route path elements are removed from the route when recognized. This lets wrapper methods continue parsing the remainder of the route without worrying about duplicate elements.

Parameters
$route : array<string|int, mixed>

Array of routing path components.

Return values
array<string|int, mixed> —

URL query parameters
