如何从Symfony2 config.yml中读取配置设置？ [英] How do I read configuration settings from Symfony2 config.yml?

问题描述

我已经为我的config.yml文件添加了一个设置：

  app.config：
 contact_email ：[e-mail] 
 ... 
  

对我来说，不知道如何读取它变成一个变量。我在我的控制器中尝试过这样的操作：

  $ recipient = 
 $ this-> container-> ; getParameter（'contact_email'）; 
  

但我得到一个错误：

参数contact_email必须定义
。

，我也在Symfony2重新加载的网站文档，无处不在，但我找不到如何做这个。

现在可能只是太累了。 c>

code> app.config ，在参数条目中定义它：

 参数：
 contact_email：[e-mail] 
  

你应该发现你在你的控制器中的呼叫现在工作。

I have added a setting to my config.yml file as such:

app.config:
    contact_email: [e-mail]
    ...

For the life of me, I can't figure out how to read it into a variable. I tried something like this in one of my controllers:

$recipient =
$this->container->getParameter('contact_email');

But I get an error saying:

The parameter "contact_email" must be defined.

I've cleared my cache, I also looked everywhere on the Symfony2 reloaded site documentation, but I can't find out how to do this.

Probably just too tired to figure this out now. Can anyone help with this?

解决方案

Rather than defining contact_email within app.config, define it in a parameters entry:

parameters:
    contact_email: [e-mail]

You should find the call you are making within your controller now works.
