Interfaces
Renderer\RendererInterface
Renderer\RendererInterface
is an interface to provide a common rendering API.
Classes
Renderer\MustacheRenderer
Renderer\PhpEngineRenderer
Renderer\PlatesRenderer
Renderer\TwigRenderer
All classes except PlatesRenderer
extend the parent rendering engine classes to enable those engines to implement the RendererInterface
.
Usage
Renderer\RendererInterface
classes can be instantiated in the same manner as their parent implementations, please refer to the vendor documentation for further details.
To assist with using these classes, example service providers are shared in this repository's samples folder, as well as the sample configuration which these providers are dependent upon.
Example Use Case
An example use of the Renderer\RendererInterface
is provided here. In this example, our controller class builds a view class based on Joomla\View\ViewInterface
and injects the required dependencies.
Sample Controller:
namespace Joomla\Controller; use Joomla\Renderer\RendererInterface; use Joomla\Controller\AbstractController; use Joomla\DI\ContainerAwareInterface; use Joomla\DI\ContainerAwareTrait; use Joomla\View\ViewInterface; /** * Default controller class for the application * * @since 1.0 */ class DefaultController extends AbstractController implements ContainerAwareInterface { use ContainerAwareTrait; /** * The default view for the application * * @var string * @since 1.0 */ protected $defaultView = 'dashboard'; /** * State object to inject into the model * * @var \Joomla\Registry\Registry * @since 1.0 */ protected $modelState = null; /** * Execute the controller * * This is a generic method to execute and render a view and is not suitable for tasks * * @return boolean True if controller finished execution * * @since 1.0 * @throws \RuntimeException */ public function execute() { try { // Initialize the view object $view = $this->initializeView(); // Render our view. $this->getApplication()->setBody($view->render()); return true; } catch (\Exception $e) { throw new \RuntimeException(sprintf('Error: ' . $e->getMessage()), $e->getCode()); } } /** * Method to initialize the model object * * @return \Joomla\Model\ModelInterface * * @since 1.0 * @throws \RuntimeException */ protected function initializeModel() { $model = '\\Joomla\\Model\\' . ucfirst($this->getInput()->getWord('view')) . 'Model'; // If a model doesn't exist for our view, revert to the default model if (!class_exists($model)) { $model = '\\Joomla\\Model\\DefaultModel'; // If there still isn't a class, panic. if (!class_exists($model)) { throw new \RuntimeException(sprintf('No model found for view %s', $vName), 500); } } return new $model($this->modelState); } /** * Method to initialize the renderer object * * @return RendererInterface Renderer object * * @since 1.0 * @throws \RuntimeException */ protected function initializeRenderer() { $type = $this->getContainer()->get('config')->get('template.renderer'); // Set the class name for the renderer's service provider $class = '\\Joomla\\Service\\' . ucfirst($type) . 'RendererProvider'; // Sanity check if (!class_exists($class)) { throw new \RuntimeException(sprintf('Renderer provider for renderer type %s not found.', ucfirst($type))); } // Add the provider to the DI container $this->getContainer()->registerServiceProvider(new $class); return $this->getContainer()->get('renderer'); } /** * Method to initialize the view object * * @return ViewInterface View object * * @since 1.0 * @throws \RuntimeException */ protected function initializeView() { // Initialize the model object $model = $this->initializeModel(); $view = ucfirst($this->getInput()->getWord('view', $this->defaultView)); $class = '\\Joomla\\View\\' . $view . 'HtmlView'; // Ensure the class exists, fall back to default otherwise if (!class_exists($class)) { $class = '\\Joomla\\View\\DefaultHtmlView'; // If we still have nothing, abort mission if (!class_exists($class)) { throw new \RuntimeException(sprintf('A view class was not found for the %s view.', $view)); } } // HTML views require a renderer object too, fetch it $renderer = $this->initializeRenderer(); // Instantiate the view now /* @type \Joomla\View\AbstractHtmlView $object */ $object = new $class($model, $renderer); // We need to set the layout too $object->setLayout(strtolower($view) . '.' . strtolower($this->getInput()->getWord('layout', 'index'))); return $object; } }
The view class in this example is extended from this sample class which extends \Joomla\View\AbstractView
:
namespace Joomla\View; use Joomla\Renderer\RendererInterface; use Joomla\Model\ModelInterface; use Joomla\View\AbstractView; /** * Abstract HTML View class * * @since 1.0 */ abstract class AbstractHtmlView extends AbstractView { /** * The data array to pass to the renderer engine * * @var array * @since 1.0 */ private $data = array(); /** * The name of the layout to render * * @var string * @since 1.0 */ private $layout; /** * The renderer object * * @var RendererInterface * @since 1.0 */ private $renderer; /** * Class constructor * * @param ModelInterface $model The model object. * @param RendererInterface $renderer The renderer object. * * @since 1.0 */ public function __construct(ModelInterface $model, RendererInterface $renderer) { parent::__construct($model); $this->setRenderer($renderer); } /** * Retrieves the data array * * @return array * * @since 1.0 */ public function getData() { return $this->data; } /** * Retrieves the layout name * * @return string * * @since 1.0 * @throws \RuntimeException */ public function getLayout() { if (is_null($this->layout)) { throw new \RuntimeException('The layout name is not set.'); } return $this->layout; } /** * Retrieves the renderer object * * @return RendererInterface * * @since 1.0 */ public function getRenderer() { return $this->renderer; } /** * Method to render the view. * * @return string The rendered view. * * @since 1.0 * @throws \RuntimeException */ public function render() { return $this->getRenderer()->render($this->getLayout(), $this->getData()); } /** * Sets the data array * * @param array $data The data array. * * @return $this Method allows chaining * * @since 1.0 */ public function setData(array $data) { $this->data = $data; return $this; } /** * Sets the layout name * * @param string $layout The layout name. * * @return $this Method allows chaining * * @since 1.0 */ public function setLayout($layout) { $this->layout = $layout; return $this; } /** * Sets the renderer object * * @param RendererInterface $renderer The renderer object. * * @return $this Method allows chaining * * @since 1.0 */ public function setRenderer(RendererInterface $renderer) { $this->renderer = $renderer; return $this; } }
The view class for our view as established in the above sample controller:
namespace Joomla\View; use Joomla\Model\DefaultModel; /** * HTML view class for the Dashboard * * @since 1.0 */ class DashboardHtmlView extends AbstractHtmlView { /** * Redeclared model object for proper typehinting * * @var DefaultModel * @since 1.0 */ protected $model; /** * Method to render the view. * * @return string The rendered view. * * @since 1.0 */ public function render() { $this->setData(['data' => $this->model->getData()]); return parent::render(); } }
Installation via Composer
