Routing and middlewares
This package uses two Jaxon PSR middlewares, one to load the Jaxon config, and the other to process Jaxon requests. The Jaxon config middleware must be attached to all the routes where the Jaxon features are enabled, while the later must be attached to the route that processes Jaxon requests.
<?php use Psr\Http\Message\ServerRequestInterface as Request; use Psr\Http\Server\RequestHandlerInterface as RequestHandler; use Slim\Factory\AppFactory; use Slim\Psr7\Response; use function Jaxon\jaxon; require __DIR__ . '/../vendor/autoload.php'; $app = AppFactory::create(); // Jaxon middleware to load config // Set a container if you need to use its services in Jaxon classes. // Set a logger if you need to send messages to your logs in Jaxon classes. $jaxonConfigMiddleware = function(Request $request, RequestHandler $handler) { return jaxon()->psr() // Uncomment the following line to set a container // ->container($container) // Uncomment the following line to set a logger // ->logger($logger) ->config(__DIR__ . '/../config/jaxon.php')->process($request, $handler); }; // Process Jaxon ajax requests $app->group('/', function() use($app) { // Jaxon middleware to process ajax requests $jaxonAjaxMiddleware = function(Request $request, RequestHandler $handler) { return jaxon()->psr()->ajax()->process($request, $handler); }; $app->post('/jaxon', function($request, $response) { // Todo: return an error. Jaxon could not find a plugin to process the request. })->add($jaxonAjaxMiddleware); // Insert Jaxon codes in a page $app->get('/', function($request, $response) { // Display a page with Jaxon js and css codes. $jaxon = jaxon()−>app(); $css = $jaxon->css(); $js = $jaxon->js(); $script = $jaxon->script(); // Display the page ... }); })->add($jaxonConfigMiddleware);
Setting the view renderer
The Slim framework provides two components for view rendering, and both can be used with the Jaxon view renderer.
The Twig-View component displays Twig views.
use Jaxon\Slim\Helper; use Psr\Http\Message\ServerRequestInterface as Request; use Psr\Http\Server\RequestHandlerInterface as RequestHandler; use Slim\Views\TwigMiddleware; // Add Twig-View Middleware $twig = Helper::twig(__DIR__ . '/../templates', ['cache' => false]); $app->add(TwigMiddleware::create($app, $twig)); $jaxonConfigMiddleware = function(Request $request, RequestHandler $handler) { return jaxon()->psr() ->view('twig', '.html.twig', function() use($request) { return Helper::twigView($request); }) ->config(__DIR__ . '/../jaxon/config.php') ->process($request, $handler); };
The PHP-View component displays PHP views.
$jaxonConfigMiddleware = function(Request $request, RequestHandler $handler) { return jaxon()->psr() ->view('php', '.php', function() { return Helper::phpView(__DIR__ . '/../templates'); }) ->config(__DIR__ . '/../jaxon/config.php') ->process($request, $handler); };
Usage
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 Slim application.
The following options can be defined in the app
section of the config file.
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.
Usage
The Jaxon classes
The Jaxon classes can inherit from \Jaxon\App\CallableClass
.
By default, they are located in the jaxon/ajax
dir of the Slim application, and the associated namespace is \Jaxon\Ajax
.
This is an example of a Jaxon class, defined in the ROOT/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; } }
