Jaxon Library for CodeIgniter

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

Features

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

Installation

First install CodeIgniter version 3.

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

{
    "require": {
        "jaxon-php/jaxon-codeigniter": "~3.0",
    }
}

Copy the content of the app/ directory of this repo to the application/ dir of the CodeIgniter application. This will install the Jaxon library for CodeIgniter, as well as the controller to process Jaxon requests and a default config file.

The version 3 of the CodeIgniter framework does not natively support Composer. The Composer vendor/autoload.php file must therefore be manually included in the application.

Configuration

The settings in the 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 CodeIgniter 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 APPPATH . '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 CodeIgniter controller using the Jaxon library.

class Demo extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        // Load the Jaxon library
        $this->load->library('jaxon');
    }

    public function index()
    {
        // Print the page
        $this->load->view('index', array(
            'JaxonCss' => $this->jaxon->css(),
            'JaxonJs' => $this->jaxon->js(),
            'JaxonScript' => $this->jaxon->script()
        ));
    }
}

The controller must inherit from the Jaxon_Controller provided in this package, and call its contructor.

The calls to $this->jaxon->css(), $this->jaxon->js() and $this->jaxon->script() return the CSS and javascript codes generated by Jaxon, which are inserted into the page.

The Jaxon classes

The Jaxon classes can inherit from \Jaxon\CallableClass. By default, they are located in the APPPATH/jaxon/app dir of the CodeIgniter application, and the associated namespace is \Jaxon\App.

This is a simple example of a Jaxon class, defined in the APPPATH/jaxon/app/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 app/controllers/jaxon/Process.php file. The jaxon/process route linked by default to the Process::index() method.
