text 将Twig扩展添加到Slim Framework V3

Posted 2021-05-01

<?php

namespace App\TwigExtension;

class IsLoggedIn extends \Slim\Views\TwigExtension
{
    public function __construct()
    {
    }

    public function getName()
    {
        return 'isLoggedIn';
    }

    public function getFunctions()
    {
        return [
            new \Twig_SimpleFunction('isLoggedIn', array($this, 'isLoggedIn'))
        ];
    }

    public function isLoggedIn ()
    {
        return \App\Helper\Acl::isLoggedIn();
    }
}



-------------------------------------------------------------------------------------------

Then in dependencies.php add the IsLoggedIn() extension to the Twig setup section: 

$container['view'] = function ($c) {
    $settings = $c->get ('settings');
    $view = new \Slim\Views\Twig ($settings['view']['template_path'], $settings['view']['twig']);

    // Add extensions
    $view->addExtension (new Slim\Views\TwigExtension($c->get ('router'), $c->get ('request')->getUri ()));
    $view->addExtension (new Twig_Extension_Debug());
    $view->addExtension (new App\TwigExtension\IsLoggedIn());
    $view['settings'] = $settings; // Do we need this?

    return $view;
};
