Php 如何在symfony twig文件中使用全局变量？

我已经在app/config/config.yml中完成了设置

twig:

globals:

  mandatory_note: %mandatory_note%

参数也在config.yml文件中设置

参数：

mandatory_note: "Note: * marked fields are mandatory"

在twig文件中，我访问了变量

{{必须注意}

但还是会出错。即，强制注释变量不存在

这是我的config.yml文件

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: services.yml }

    #esi:             ~

你需要把它放在树枝下面。就像这样：

twig:
    globals:
        mandatory_note: %mandatory_note%

---

还要确保parameters.yml文件中定义了

必填\u note

。要测试全局是否有效，只需使用

“testString”

而不是

%mandatory\u note%

将它们放在一起，像这样会怎么样

twig:
    debug:            "%kernel.debug%"
    strict_variables: "%kernel.debug%"
    globals:
        mandatory_note: "%mandatory_note%"

---

我得到了解决方案，我在parameters.yml文件中添加了以下代码：

它终于开始工作了。

压痕的可能重复也是正确的。文件中有任何设置吗？没有。请提供完整的config.yml文件我附加了我的config.yml文件没有朋友仍然是相同的错误。.“变量”强制注释“不存在”。（这正是我的意思：）仍然会出现错误“您请求了一个不存在的参数”强制注释：（您的参数不存在。是否已定义？是。在所附的配置文件中，有参数节I定义了参数“强制注意”将参数移到细枝声明上方。

parameters:
    mandatory_note: "Note: * marked fields are mandatory"

twig:
    globals:
        mandatory_note: "%mandatory_note%"
