Jaxon Library for Symfony

This package integrates the Jaxon library into the Symfony framework.

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-symfony": "~2.0"
}

Declare the Jaxon bundle in the app/AppKernel.php file.

$bundles = array(
    ...
    new Jaxon\AjaxBundle\JaxonAjaxBundle(),
);

Setup the default routing for Jaxon request by adding the following line in the app/config/routing.yml config file.

jaxon_ajax:
    resource: "@JaxonAjaxBundle/Resources/config/routing.yml"
    prefix:   /

Import the service definition and configuration file of the Jaxon bundle in the app/config/config.yml config file.

imports:
    ...
    - { resource: jaxon.yml }
    - { resource: "@JaxonAjaxBundle/Resources/config/services.yml" }

Create and edit the app/config/jaxon.yml file to suit the needs of your application. A sample config file is available online at the examples repo.

Configuration

The settings in the app/config/jaxon.yml 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 Symfony 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 | 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 Symfony controller using the Jaxon library.

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

class DemoController extends Controller
{
    public function indexAction(Request $request)
    {
        // Register the Jaxon classes
        $jaxon = $this->get('jaxon.ajax');
        $jaxon->register();
        // Print the page
        return $this->render('demo/index.html.twig',
            'jaxon_css' => $jaxon->css(),
            'jaxon_js' => $jaxon->js(),
            'jaxon_script' => $jaxon->script()
        ]);
    }
}

Before it prints the page, the controller makes a call to $jaxon->register() to export the Jaxon classes. Then it 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 must inherit from \Jaxon\Sentry\Armada. By default, they are located in the jaxon/Classes dir of the Symfony 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\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/Controllers/JaxonController.php file. The /jaxon route is defined in the src/Resources/config/routing.yml file, and linked to the JaxonController::indexAction() 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.
