Rain Support

The October Rain Support contains common classes relevant to supporting the other October Rain libraries. It adds the following features:

Scaffolding

See the Scaffolding Commands section of the Console documentation.

A true Singleton trait

A true singleton is a class that can ever only have a single instance, no matter what. Use it in your classes like this:

class MyClass
{
    use \October\Rain\Support\Traits\Singleton;
}

$class = MyClass::instance();

Global helpers

input()

Similar to Input::get() this returns an input parameter or the default value. However it supports HTML Array names. Booleans are also converted from strings.

$value = input('value', 'not found');
$name = input('contact[name]');
$city = input('contact[location][city]');

Event emitter

Adds event related features to any class.

Attach to a class

class MyClass
{
    use October\Rain\Support\Traits\Emitter;
}

Bind to an event

$myObject = new MyClass;
$myObject->bindEvent('cook.bacon', function(){
    echo 'Bacon is ready';
})

Trigger an event

// Outputs: Bacon is ready
$myObject->fireEvent('cook.bacon');

Bind to an event only once

$myObject = new MyClass;
$myObject->bindEvent('cook.soup', function(){
    echo 'Soup is ready. Want more? NO SOUP FOR YOU!';
}, true);

Bind an event to other object method

$myObject->bindEvent('cook.eggs', [$anotherObject, 'methodToCookEggs']);

Unbind an event

$myObject->unbindEvent('cook.bacon');
$myObject->unbindEvent(['cook.bacon', 'cook.eggs']);
