如何添加扩展名在twig中添加全局

Question

当我尝试在树枝中添加扩展添加全局

$view = new \Slim\Views\Twig($settings['template_path'], [
    'debug' => $settings['debug'],
    'cache' => $settings['cache_path']
]);
// Add extensions
$view->addExtension(new \Slim\Views\TwigExtension(
    $c['router'],
    $c['request']->getUri()
));
$view->addExtension(new \Core\TwigFunction());  
$view->addExtension(new Twig_Extension_Debug());
$view = new Twig_Environment();;
$view->addGlobal('session', $_SESSION);

我收到：

  

调用未定义的方法Twig_Environment :: offsetSet（）

Answer 1

在第

行

$view = new Twig_Environment();

您正在覆盖$view变量。删除该行应解决问题，因为slim/twig-view为您设置了Twig环境。
