如何添加擴展加入全球在樹枝

Question

當我嘗試添加添加擴展全球在樹枝

$view = new \Slim\Views\Twig($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：

調用未定義的方法Twig_Environment :: offsetSet（）

在線

$view = new Twig_Environment(); 

您正在覆蓋$view變量。刪除該行應該解決問題，因爲slim/twig-view爲您設置了Twig環境。
