Question

I know you can set global variables in TWIG this way :

# config.yml
# Twig Configuration
twig:
    debug:            "%kernel.debug%"
    strict_variables: "%kernel.debug%"
    cache : false
    globals :
        server : 127.0.0.1

Now what I want is to create a custom variable server that uses the preexistent global variable app.request.host. I can reference that variable in a TWIG template, but how can I do that in a YML file ?

In one sentence : I want to create a global TWIG variable from another one.

为什么不参加参数。只需将它放在你的parameters.yml

中

server: 127.0.0.1

之后你可以在yml文件中引用它，如下所示：

"%server%"

将它添加到全局变量中：

twig:
    globals:
        server: '%server%'

如果你需要在控制器中，那么使用这种方法：

$this->getParameter("server")

How can I modify/extend a global TWIG variable?
