How do you implement Yii’s “event handling” system?
Answer: In Yii, event handling is implemented using the observer pattern. You can create events by defining them in your classes and using the `Event` class. To handle events, follow these steps:
1. Define Events: Create a class that extends `yiibaseEvent`, and define your events as constants or properties.
2. Attach Event Handlers: Use the `on()` method to bind event handlers to the events, specifying the event name and the handler method.
3. Trigger Events: Call the `trigger()` method on the event sender to fire the event when certain actions occur.
4. Create Handler Methods: Define methods that will handle the events and receive the event object as a parameter.
Here’s a simple example:
“`php
class MyComponent extends yiibaseComponent {
const EVENT_SOMETHING_HAPPENED = ‘somethingHappened’;
public function doSomething() {
// Do something…
$this->trigger(self::EVENT_SOMETHING_HAPPENED);
}
}
$myComponent = new MyComponent();
$myComponent->on(MyComponent::EVENT_SOMETHING_HAPPENED, function($event) {
// Handle the event
});
$myComponent->doSomething(); // This will trigger the event
“`
