Events
The event class lets you register event listeners and trigger them.
Usage
The register method lets you register an event listener that will run when triggered.
Event::register('foobar', function()
{
return 'foobar event 1';
});
// You can register multiple handlers for the same event.
// They will be run in the order they were registered.
Event::register('foobar', function()
{
return 'foobar event 2';
});
The registered method will return TRUE if an event listener has been registered and FALSE if not.
$registered = Event::registered('foobar'); // True
The clear method will clear all event listeners registered for an event.
Event::clear('foobar');
The override method will clear all previously registered handlers for an event before registering a new handler.
Event::override('foobar', function()
{
return 'foobar event 1';
});
The trigger method run all handlers for the registered event and return an array containing all the return values.
$values = Event::trigger('foobar');
// You can also pass an array of values
$values = Event::trigger('foobar', array(1, 2, 3));
The first method run all handlers for the registered event and return the result of the first one.
$value = Event::first('foobar');
// You can also pass an array of values
$values = Event::first('foobar', array(1, 2, 3));
