Components¶

Read the CakePHP docs on Components: http://book.cakephp.org/2.0/en/controllers/components.html.

What is a Component?¶

Components are packages of logic that are shared between controllers. If you find yourself wanting to copy and paste things between controllers, you might consider wrapping some functionality in a component.

Code¶

Assuming you want to create an Example component, it would be found at /app/Controller/Component/ExampleComponent.php:

<?php
class ExampleComponent extends Component {

    public function myMethod() {
        // your code here
    }

}

Plugin components¶

If it Example plugin’s component, it would be found at /app/Plugin/Example/Controller/Component/ExampleComponent.php.

Using Components in Controllers¶

<?php
class RecipesController extends AppController {

    public $components = array(
        'Example', // 'Example.Example' if it is from Example plugin
    );

    public function view($id)     {
        // call component method
        $this->Example->myMethod();
    }

}
