Allow access to $app from within authenticator, error

[sivann]

Useful in many cases to have access to $app and container. E.g. In error, it would be useful to have access to the renderer ($app->getContainer()->get('view') in order to render an error page.

In authenticator, also useful to access app's Model methods, settings, etc.

Sorry I do not understand. Can you show some example code what you are trying to achieve.

I may be wrong about it, but here's the error part definition. How could I access $app without using "global"?

$app->add(new \Slim\Middleware\HttpBasicAuthentication([
    "error" => function ($request, $response, $arguments) { //on 401
        global $app; //ugly, but how else without modifying the module..

        $container = $app->getContainer();
        $renderer=$container->get('view');

        $renderer->render($response,'gotohome.twig',array('uri'=>$request->getUri(),'session'=>$_SESSION,'message'=>$arguments['message']) );

        return $response;
    }
...

Probably the __construct of HttpBasicAuthentication could take $app as argument, and also pass it as arguments to its callbacks.

PHP has the use keyword which can be used for passing variables to closures.

$app = new \Slim\App;

$app->add(new \Slim\Middleware\HttpBasicAuthentication([
    "error" => function ($request, $response, $arguments) use ($app) {
        /* do something with $app */
    }
]));

I've completely forgotten about that. Thanks a lot for your time and advice !
