Jaxon Library for Zend Framework

This package integrates the Jaxon library with the Zend Framework 2.3+ and 3.

Features

Automatically register Jaxon classes from a preset directory.
Read Jaxon options from a config file.

Installation

Add the following lines in the composer.json file, and run the composer update command.

"require": {
    "jaxon-php/jaxon-zend": "~3.1"
}

Add the Jaxon module to the modules entry in the config/application.config.php or config/modules.config.php config file.

    'modules' => [
        'Application',
        'Jaxon\Zend',
    ),

Zend Framework 2

Edit the module/Application/config/module.config.php as follow.

1. Import the Jaxon classes into the current namespace

use Jaxon\Zend\Factory\Zf2ControllerFactory;

2. Register the Jaxon plugin with the Service Manager

    'service_manager' => [
        'invokables' => [
            'JaxonPlugin' => 'Jaxon\Zend\Controller\Plugin\JaxonPlugin',
        ),
    ),

3. Use the provided factory to create both the application controller and the Jaxon ZF controller.

    'controllers' => [
        'factories' => [
            'Application\Controller\Demo' => Zf2ControllerFactory::class,
            'Jaxon\Zend\Controller\Jaxon' => Zf2ControllerFactory::class,
        ),
    ),

This factory injects the Jaxon plugin into the ZF controller constructor.

4. Route the Jaxon request URI to the plugin controller.

    'router' => [
        'routes' => [
            // Route to the Jaxon request processor
            'jaxon' => [
                'type' => 'Zend\Mvc\Router\Http\Literal',
                'options' => [
                    'route'    => '/jaxon',
                    'defaults' => [
                        'controller' => 'Jaxon\Zend\Controller\Jaxon',
                        'action'     => 'index',
                    ),
                ),
            ),
        ),
    ),

Zend Framework 3

Edit the module/Application/config/module.config.php file as follow.

Import the Jaxon classes into the current namespace

use Jaxon\Zend\Factory\Zf3ControllerFactory;
use Jaxon\Zend\Controller\Plugin\JaxonPlugin;
use Jaxon\Zend\Controller\JaxonController;

    'service_manager' => [
        'invokables' => [
            'JaxonPlugin' => JaxonPlugin::class,
        ],
    ],

    'service_manager' => [
        'factories' => [
            JaxonPlugin::class => InvokableFactory::class,
        ],
        'aliases' => [
            'JaxonPlugin' => JaxonPlugin::class,
        ],
    ],

Use the provided factory to create both the application controller and the Jaxon ZF controller.

    'controllers' => [
        'factories' => [
            Controller\DemoController::class => Zf3ControllerFactory::class,
            JaxonController::class => Zf3ControllerFactory::class,
        ],
    ],

This factory injects the Jaxon plugin into the ZF controller constructor.

Route the Jaxon request URI to the Jaxon Controller

    'router' => [
        'routes' => [
            // Route to the Jaxon request processor
            'jaxon' => [
                'type' => Literal::class,
                'options' => [
                    'route'    => '/jaxon',
                    'defaults' => [
                        'controller' => JaxonController::class,
                        'action'     => 'index',
                    ],
                ],
            ],
        ],
    ],

Configuration

The config of the Jaxon library is defined in the config/jaxon.config.php file. A sample config file is provided in this repo.

The settings in the config/jaxon.config.php config file are separated into two sections. The options in the lib section are those of the Jaxon core library, while the options in the app sections are those of the Zend Framework application.

The following options can be defined in the app section of the config file.

| Name | Description | |------|---------------| | directories | An array of directory containing Jaxon application classes | | views | An array of directory containing Jaxon application views | | | | |

By default, the views array is empty. Views are rendered from the framework default location. There's a single entry in the directories array with the following values.

| Name | Default value | Description | |-----------|-----------------|-------------| | directory | {app_dir}/jaxon/Classes | The directory of the Jaxon classes | | namespace | \Jaxon\App | The namespace of the Jaxon classes | | separator | . | The separator in Jaxon class names | | protected | empty array | Prevent Jaxon from exporting some methods | | | | |

Usage

This is an example of a Zend Framework controller using the Jaxon library.

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Jaxon\Zend\Controller\Plugin\JaxonPlugin;

class DemoController extends AbstractActionController
{
    /
     * @var \Jaxon\Zend\Controller\Plugin\JaxonPlugin
     */
    protected $jaxon;

    public function __construct(JaxonPlugin $jaxon)
    {
        $this->jaxon = $jaxon;
    }

    public function indexAction()
    {
        $view = new ViewModel([
            'jaxonCss' => $this->jaxon->css(),
            'jaxonJs' => $this->jaxon->js(),
            'jaxonScript' => $this->jaxon->script(),
        ]);
        $view->setTemplate('demo/index');
        return $view;
    }
}

Before it prints the page, the controller calls the $jaxon->css(), $jaxon->js() and $jaxon->script() functions to get the CSS and javascript codes generated by Jaxon, which it inserts into the page.

The Jaxon classes

The Jaxon classes can inherit from \Jaxon\CallableClass. By default, they are loaded from the jaxon/Classes dir at the root of the Zend Framework application, and the associated namespace is \Jaxon\App.

This is a simple example of a Jaxon class, defined in the jaxon/Classes/HelloWorld.php file.

namespace Jaxon\App;

class HelloWorld extends \Jaxon\CallableClass
{
    public function sayHello()
    {
        $this->response->assign('div2', 'innerHTML', 'Hello World!');
        return $this->response;
    }
}

Request processing

By default, the Jaxon request are handled by the controller in the src/Controller/JaxonController.php file. The /jaxon route is linked by default to the JaxonController::actionIndex() method.
