Jaxon integration for CodeIgniter 4

This package integrates the Jaxon library into the CodeIgniter 4 framework.

Installation

The version 4 of the package requires CodeIgniter version 4.

Install the package with Composer.

composer require jaxon-php/jaxon-codeigniter ^4.0

Or

{
    "require": {
        "jaxon-php/jaxon-codeigniter": "^4.0",
    }
}

And run composer install.

Filter

This package provides a filter that must be attached to the routes to all the pages where the Jaxon features are enabled.

In the app/Config/Routes.php file, a route must be defined for Jaxon requests.

// Add the Jaxon filter to Jaxon-enabled routes.
$routes->get('/', 'Demo::index', ['filter' => JaxonConfigFilter::class]);

// Jaxon request processing route.
$routes->post('/jaxon', 'Demo::jaxon', ['filter' => JaxonConfigFilter::class]);

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

namespace App\Controllers;

use Jaxon\Demo\Ajax\Bts;
use Jaxon\Demo\Ajax\Pgw;

use function view;

class Demo extends BaseController
{
    public function index()
    {
        $jaxon = jaxon()->app();

        // Print the page
        return view('demo/index', [
            'jaxonCss' => $jaxon->css(),
            'jaxonJs' => $jaxon->js(),
            'jaxonScript' => $jaxon->script(),
            'pageTitle' => "CodeIgniter Framework",
            // Jaxon request to the Bts Jaxon class
            'bts' => $jaxon->request(Bts::class),
            // Jaxon request to the Pgw Jaxon class
            'pgw' => $jaxon->request(Pgw::class),
        ]);
    }

    public function jaxon()
    {
        $jaxon = jaxon()->app();
        if(!$jaxon->canProcessRequest())
        {
            // Jaxon failed to find a plugin to process the request
            return; // Todo: return an error message
        }

        $jaxon->processRequest();
        return $jaxon->httpResponse();
    }
}

Configuration

Copy the config/Jaxon.php file in this package to the app/Config dir of the CodeIgniter app.

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 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 'jaxon/ajax' The directory of the Jaxon classes
namespace \Jaxon\Ajax The namespace of the Jaxon classes
separator . The separator in Jaxon class names
protected empty array Prevent Jaxon from exporting some methods

Usage

The Jaxon classes

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

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

namespace Jaxon\Ajax;

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