symfony - 如何使用 KNP Menu Bundle 2 创建面包屑？

Question

所以我构建了一个菜单，如下例所示:

<?php namespace AppBundle\Menu;

use Doctrine\ORM\EntityManager;
use Knp\Menu\FactoryInterface;
use Knp\Menu\MenuFactory;

class AdminMenuBuilder
{

    public function sidebarMenu(FactoryInterface $factory, array $options)
    {
    $menu = $factory->createItem('root', array(
        'navbar' => true,
        'childrenAttributes' => [
            'class' => 'nav main-menu',
        ],
    ));


    $menu->addChild('Dashboard')
         ->setAttributes([
            'icon' =>'fa fa-dashboard',
            'class' => 'dropdown',
             'dropdown' => true
         ]);

    $menu['Dashboard']->addChild('Details', ['route' => 'app.admin.dashboard']);
    $menu['Dashboard']->addChild('Details 2', ['route' => 'app.admin.dashboard']);

    $menu->addChild('Users', ['route' => 'app.admin.dashboard.users'])
        ->setAttribute('icon', 'fa fa-users');


        return $menu;
    }
}

如何使用 KNPMenuBundle v2 创建面包屑？我正在使用 symfony2 2.7.5

Answer 1

KnpMenuBundle 2.1.0(几周前发布)有一个 knp_menu_get_breadcrumbs_array() 函数可供您使用。例如:

{% set item = knp_menu_get('some_menu_item') %}
{% set breadcrumbs = knp_menu_get_breadcrumbs_array(item) %}
{% for breadcrumb in breadcrumbs %}
  <a href="{{ breadcrumb.url }}">{{ breadcrumb.label }}</a>
{% endfor %}
