Class: RESTfulRouter

RESTful router, provide a quick way to register RewriteRoute with HTTP method adaptation(RESTful).

$router = new RESTfulRouter

Create a router.

$router->on($method, $url, $controller, $action)

• $method String: HTTP method name, support wildcard * to match all methods.
• $url String
• $controller String: controller class name
• $action String: method name of controller

Tips. you can register multi methods in single on(), use space to separate methods, eg. $router->on('get post', 'user/:id', 'user', 'show')

Example

class Bootstrap extends \Yaf\Bootstrap_Abstract {
    // default YAF style route registration
    function _initRoute(\Yaf\Dispatcher $dispatcher) {
        $router = $dispatcher->getRouter();
        
        // default yaf rewrite route
        $router->addRoute('dog', new \Yaf\Route\Rewrite('dogs', array('controller' => 'dog', 'action' => 'index')));
        $router->addRoute('dog_show', new \Yaf\Route\Rewrite('dogs/:id', array('controller' => 'dog', 'action' => 'show')));
        $router->addRoute('dog_create', new \Yaf\Route\Rewrite('dogs/create', array('controller' => 'dog', 'action' => 'create')));
        $router->addRoute('dog_destroy', new \Yaf\Route\Rewrite('dogs/:id/delete', array('controller' => 'dog', 'action' => 'destroy')));
    }

    
    // RESTful style
    function _initRESTfulRoute() {
        $router = new \Yaf\Extras\RESTfulRouter;
        $router->on('post', 'cat', 'cat', 'create');
        $router->on('get', 'cat/:id', 'cat', 'show');
        $router->on('delete', 'cat/:id', 'cat', 'destroy');
        
        $router->on('put patch', 'cat/:id', 'cat', 'update');

        $router->on('*', 'pig/:id', 'pig', 'what');
    }
}

Strict Mode

new RESTfulRouter(true) to open strict mode.

In this mode, uri will matches strictly and new <name> style syntax was introduced.

eg. '/user/<name>' will match '/user/micheal', but not match '/user/micheal/age', also not match '/user/micheal/'.

Type filter supported by <name:filter>.

Current filters

• int : pure number

eg. '/user/<id:int>' will match '/user/123, but not match '/user/micheal'.

Because it base on YAF\Route\Regex, some regex can be used. And currently you can't use '()', it will cause error.

eg. '/blog/?' will match '/blog' or '/blog/'.

Class: AdaptiveView

Render with different way(renderer) according to view file's extension name. Use default Yaf Simple View as fallback if no renderer matched.

$view = new AdaptiveView($path = '{yaf.application.directory}/views/')

• $path String: path of view files located, default is '{yaf.application.directory}/views/'

Create a view.

$view->on($extname, $renderder)

• $extname String: view file's extension name
• $renderer($file, $data) Function: called when extname matched, should return the rendered result.

Register a renderer with extname.

$view->*

Other common methods see Yaf/View/Interface

Example

Bootstrap.php

class Bootstrap extends \Yaf\Bootstrap_Abstract {
    function _initView(\Yaf\Dispatcher $dispatcher) {
        $view = new \Yaf\Extras\AdaptiveView;
        $path = $view->getScriptPath();
    
        // plain text TEST
        $view->on('txt', function ($file, $data) use ($path) {
            return file_get_contents( $path .$file ) .' THIS IS JUST A TEST';
        });

        // twig
        $view->on('twig', function ($file, $data) use ($path) {
            $loader = new Twig_Loader_Filesystem($path);
            $twig = new Twig_Environment($loader);
            return $twig->loadTemplate($file)->render($data);
        });

        $dispatcher->disableView(); // disable auto-render
        $dispatcher->setView($view);
    }
}

Now you can use this view in YourController.php

class TestController extends \Yaf\Controller_Abstract {
    public function testAction() {
        $view = $this->getView();
        $view->assign('content', 'Hello World'); 
        $view->display('text.txt');
        // $view->display('text.twig'); // render use twig
    }
}

Class: ExtendedController

Common controller base on \Yaf\Controller_Abstract with many useful methods;

flash

Flash messaging

$this->flash($msg, $type = 'info')

Store message for next request

$this->flashNow($msg, $type = 'info')

For current request

$this->getFlash()

Retrieve message for current request

example

class FooController extends ExtendedController {
    public function indexAction() {
        $this->flash('yep', 'success');
        $this->flashNow('nope', 'error');

        foreach ($this->getFlash() as $flash) {
            echo $flash['msg']; // 'nope' in current, 'yep' for next
            echo $flash['type'];
        }
    }
}
