这不能在Twig中完成,如模板的编译源中所示,每个包含的templats都有自己的私有范围,因为上下文数组是基于值而不是引用

$this-> loadTemplate(“bar.twig”,“main.twig”,2) – > display($context);

然后在包含的模板中调用doDisplay

protected function doDisplay(array $context,array $blocks = array())

注意

你可以通过创建自己的Twig_Environment和Twig_Template来改变这种行为,但是快速浏览一下我会发现你需要覆盖一些功能.

main.twig

{% set foo = 'bar' %}

{% include 'bar.twig' %}

Foo in foo: {{ foo }}

bar.twig

{% set foo = 'foo' %}

Foo in bar: {{ foo }}
