KNP Menu Bundle with HTML Special Chars

I'm using the KNP Menu Bundle within my Symfony2 project and create my Menus as a service.

I have the problem that the Route Labels quotes and other special chars won't displayed correctly.

As an example:

Test Text & Stuff will be displayed as Test Text & Stuff and I can't figure out how do deal with it.

I'm creating the route as following:

$menu->addChild('seller', array(
    'route' => 'routename',
    'routeParameters' => $array,
    'label' => $sellername
))->setLinkAttribute('class', 'dark-color active-hover');

I tried to this commands to get rid of it:

  1. html_entity_decode()
  2. htmlspecialchars_decode()
  3. htmlspecialchars()
  4. htmlentities()

But neither of them worked. It wouldn't be a big deal if the browser would translate them corectly, but the browser isn't doing it because of this:

                 Test Text & Stuff                     

There's plenty of whitespace before and after my text and I can't figure out where it's comming from. I trimed the $sellername and I also added the trim commands from twig into the knp_menu.html.twig.

Any suggestions how I can deal with this situation?

Edit:

What I figured out now is that if I manually remove the whitespaces from the text the text will be displayed correctly. I tried to trim the whitespaces with javascript, but I had no success with it by now.

Edit:

Here's the knp_menu.html.twig template

{% extends 'knp_menu.html.twig' %}

{% block item %}

生素做什么?

默认情况下,在Twig中显示内容时(使用{{ }}),Twig会将其转义以确保其安全。我们不希望任何邪恶的HTML在我们的页面中结束。

有时我们要显示的内容已经是HTML,因此我们不想再次将其转义。那就是raw过滤器进来的地方!它告诉twig它刚刚“过滤”的东西已经被转义,我们希望以它的原始形式使用它(例如,不要再逃避它)。

如何使用原始

block('label')将呈现名为“label”的块。这个渲染将完成html-safe,这意味着它被转义。

通过在另一个模板中显示(通过执行{{ block('label') }}),它将再次转义。如果您不想这样,则应使用raw过滤器:{{ block('label')|raw }}

raw过滤器必须使用最后,否则无效。因此,如果要修剪渲染,请先执行此操作:{{ block('label')|trim|raw }}

PS:即使做更精细的事情,你仍然必须最后使用raw作为一个整体。例如:{{ ('<span>' ~ block('label')|trim ~ '</span>')|raw }}
