Jaxon Library for CakePHP

This package integrates the Jaxon library into the CakePHP 3 framework.

Features

  • Read Jaxon options from a file in CakePHP config format.
  • Automatically register Jaxon classes from a preset directory.

Installation

First install CakePHP version 3.

Create the composer.json file into the installation dir with the following content.

{
    "require": {
        "jaxon-php/jaxon-cake": "~2.0",
    }
}

Add the Jaxon plugin in the vendor/cakephp-plugins.php file.

return [
    'plugins' => [
        ...
        'Jaxon/Cake' => $baseDir . '/vendor/jaxon-php/jaxon-cake/',
    ]
];

Load the Jaxon plugin in the controller or in the bootstrap file.

Plugin::load('Jaxon/Cake', array('autoload' => true, 'routes' => true));

Load the Jaxon component in the controller.

$this->loadComponent('Jaxon/Cake.Jaxon');

Configuration

The settings in the config/jaxon.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 CakePHP application.

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

| Name | Description | |------|---------------| | classes | 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 classes array with the following values.

| Name | Default value | Description | |------|---------------|-------------| | directory | ROOT . '/jaxon/Controller' | 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 CakePHP controller using the Jaxon library.

namespace App\Controller;

class DemoController extends AppController
{
    public function initialize()
    {
        parent::initialize();
        // Load the Jaxon component
        $this->loadComponent('Jaxon/Cake.Jaxon');
    }

    public function index()
    {
        // Call the Jaxon module
        $this->Jaxon->register();

        $this->set('jaxonCss', $this->Jaxon->css());
        $this->set('jaxonJs', $this->Jaxon->js());
        $this->set('jaxonScript', $this->Jaxon->script());
        $this->render('demo');
    }
}

Before it prints the page, the controller makes a call to $this->Jaxon->register() to export the Jaxon classes. Then it calls the $this->Jaxon->css(), $this->Jaxon->js() and $this->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 must inherit from \Jaxon\Sentry\Armada. By default, they are located in the ROOT/jaxon/Classes dir of the CakePHP application, and the associated namespace is \Jaxon\App.

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

namespace Jaxon\App;

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

Check the jaxon-examples package for more examples.

Request processing

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

The request processing can be customized by extending the default controller and overloading the following method.

  • `public function initInstance($instance)`: called for any Jaxon class instanciated.
  • `public function beforeRequest($instance, $method, &$bEndRequest)`: called before processing the request.
  • `public function afterRequest($instance, $method)`: called after processing the request.

See [https://www.jaxon-php.org/docs/armada/bootstrap.html]() for more information about processing callbacks.
