Syntax: kernel_event_trigger(string $event)

Trigger an event. Any event can be specified, as long as it exist. See kernel_event_create for creating new events. All registered functions will be called in the order they were registered, starting with the oldest one.

Default events are, in the order they are called:

MODULESLOADED -- All the modules are loaded.
STARTUP -- About to render the page
SHOWHEADER -- Page header rendered
SHOWCONTENT -- Page content rendered
SHOWFOOTER -- Page footer rendered
SHUTDOWN -- The framework is shutting down

Note that manually calling any of these events is not recommended as it can lead to unexpected behavior.

Parameters

event
The event name to trigger

Return values

TRUE if the event has been triggered. Note that this doesn’t mean the any code was executed nor that any of the code didn’t failed at some point without crashing the framework.

FALSE if the event doesn’t exist.

Examples:

Triggering the MYCUSTOMEVENT event
kernel_event_trigger('MYCUSTOMEVENT');
