问题描述

我的 layout.html.twig

{{ render(controller('AcmeDemoBundle:Page:mainmenu')) }}

页面控制器从Doctrine中检索所有页面,并使用一组页面呈现 mainmenu.html.twig

The Page controller retrieves all pages from the Doctrine and renders mainmenu.html.twig with a set of pages.

我的 mainmenu.html.twig

{% if menu_pages is defined %}
    {% for page in menu_pages %}
        <li class="{% if app.request.attributes.get('_internal') == '_page_show' and app.request.get('id') == page.id %}active{% endif %}"><a href="{{ path('_page_show', {id: page.id}) }}">{{ page.title|e }}</a></li>
    {% endfor %}
{% endif %}

但是没有活动类显示。据了解,问题在于内部路由。如何解决?

But no active class is displayed. As far as I understand the problem is in internal routing. How to fix that?

推荐答案

更好的不要使用 {{render(controller('AcmeDemoBundle:Page :mainmenu'))}} 。当您使用服务时,它的工作更加快捷舒适。您可以创建一个将在您包含它们的任何页面上显示菜单的服务。在服务中,您可以轻松访问当前 _route 以添加活动类。

Better do not use {{ render(controller('AcmeDemoBundle:Page:mainmenu')) }}. It work more fast and comfortable when you use services instead. You can create a service which will show menu on any page where you include them. And in service you can easy get access to current _route for add active class.

但是如果你真的需要使用 {{render(controller('AcmeDemoBundle:Page:mainmenu'))}} ,那么你需要传递给他们当前的请求如下:

But if you really need to use {{ render(controller('AcmeDemoBundle:Page:mainmenu')) }}, so you need pass to them a current request like:

{{ render(controller('AcmeDemoBundle:Page:mainmenu', {'request': app.request})) }}

然后在行动传递请求到twig:

and then in action pass request to twig:

public function mainmenuAction($request) {

    return $this->render('AcmeDemoBundle:Page:mainmenu.html.twig', array('request' => $request));
}

在枝条中使用此请求:

{% if menu_pages is defined %}
    {% for page in menu_pages %}
        <li class="{% if request.get('_route') == '_page_show' and request.get('id') == page.id %}active{% endif %}"><a href="{{ path('_page_show', {id: page.id}) }}">{{ page.title|e }}</a></li>
    {% endfor %}
{% endif %}
