◆ run()

static Hooks::run	(		$event,
		array	$args = `[]`,
			$deprecatedVersion = `null`
	)

static

Call hook functions defined in Hooks::register and $wgHooks.

For the given hook event, fetch the array of hook events and process them. Determine the proper callback for each hook and then call the actual hook using the appropriate arguments. Finally, process the return value and return/throw accordingly.

For hook event that are not abortable through a handler's return value, use runWithoutAbort() instead.

Parameters

string	$event	Event name
array	$args	Array of parameters passed to hook functions
string \| null	$deprecatedVersion	[optional] Mark hook as deprecated with version number

Returns: bool True if no handler aborted the hook

Exceptions

Exception

Since: 1.22 A hook function is not required to return a value for processing to continue. Not returning a value (or explicitly returning null) is equivalent to returning true.

Deprecated:: since 1.35 Use HookContainer::run() instead, emitting warnings since 1.41

◆ runner()

static Hooks::runner ( )

static

Get a HookRunner instance for calling hooks using the new interfaces.

Classes using dependency injection should instead receive a HookContainer and construct a private HookRunner from it.

Classes without dependency injection may alternatively use ProtectedHookAccessorTrait, a trait which provides getHookRunner() as a protected method.

Since: 1.35

Access: internal: because HookRunner is intended for core only, see documentation on that class

Deprecated:: since 1.41, emitting warnings since 1.41

Returns: HookRunner

			$deprecatedVersion = `null`

Parameters

string	$event	Event name
array	$args	Array of parameters passed to hook functions
string \| null	$deprecatedVersion	[optional] Mark hook as deprecated with version number

Returns: bool Always true

Exceptions
