Events

Registering an event:

function method_one (){
    echo 'one ';
}

function method_two (){
    echo 'two ';
}

    event::on('event_trigger', 'method_one', 2);
    event::on('event_trigger', 'method_two', 1);

    event::trigger('event_trigger');

Turning events off:

	event::off('event_trigger');

	event::off('event_trigger', 'method_two');

	event::off(null, 'method_one');

Test if an event exists:

var_dump(event::exists('event_trigger'));

boolean true

Trigger an event:

	function method_name ( )
	{
		echo 'my method name';
	}

	event::on('event_name', 'method_name');

	event::trigger('event_name');

my method name

Trigger an event and pass data to it:

function method_data ( $text = '' )
	{
		echo ' 1  my method data is '.$text;
	}
	
	function method_data_two ( $text = '' )
	{
		echo ' 2 my method data is '.$text;
	}
	
	event::on('event_data', 'method_data', 1);
	event::on('event_data', 'method_data_two', 2);
	
	
	event::trigger('event_data', 'this');

1 my method data is this 2 my method data is this

Triggering a class and passing data to the method

	class my
	{
		static function method_name ( $text = '' )
		{
			echo 'my class method name is '.$text;
		}
	}
	
	event::on('event_class', 'my::method_name');
	
	event::trigger('event_class', 'Lary');

my class method name is Lary

Event chaining

	function method_sad ( $text = '' )
	{
		return str_replace('blah', "sad", $text);
	}

	function method_happy ( $text = '' )
	{
		return str_replace('sad', "happy", $text);
	}

	event::on('event_mood', 'method_sad', 1);
	event::on('event_mood', 'method_happy', 2);

	echo event::filter('event_mood', 'I am blah!');

I am happy!
