在另一个树枝变量中执行一个树枝变量 [英] Execute a twig variable inside another twig variable

问题描述

我正在做一个 symfony2 项目.在文件 html.twig 中，我有以下代码:{{ app.session.get('menu') |raw }} 指的是会话中包含的数据库表中的字段.该字段的值为:

<div class="navbar-inner"><a class="brand" href="#">Menu1</a><ul class="nav"><li class="active"><a href="#">首页</a></li><li><a href="{{ path('graphe') | raw}}">Graphe</a></li>

此时菜单已完美显示，但是当我单击Graphe"时，出现错误 No route found for GET/{{ path('graphe') |raw}} 这意味着代码不会被执行，而是被当作一个字符串.有没有其他方法可以执行.提前致谢.

解决方案

在你的 twig 模板中嵌入一个控制器来呈现你的用户菜单.有关更多信息，请参阅:

I'm working on a symfony2 project. In a file html.twig i have the following code: {{ app.session.get('menu') | raw }} that refers to a field in a database table contained in a session. The value of this field is :

<div class="navbar">
<div class="navbar-inner">
<a class="brand" href="#">Menu1</a>
<ul class="nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="{{ path('graphe') | raw}}">Graphe</a></li>
</ul>
</div>
</div>

Now at this point the menu is displayed perfectly, but when i click on "Graphe", i get the error No route found for GET /{{ path('graphe') | raw}} which means that the code is not executed but taken as a string instead. Is there any other way it can be executed. Thank you in advance.

解决方案

In your twig template embed a controller which renders your user menu. For more info see:
