如果knp_menu_render功能,我们将调用模板的appbundle:菜单:knp_menu.html.twig 然后移动演示菜单文件为src /的appbundle /资源/视图/菜单/ knp_menu.html.twig喜欢这里的文档:http://symfony.com/doc/current/book/templating.html#template-naming-and-locations
通过以下步骤:
在模板中写:
{{ knp_menu_render('AppBundle:Builder:mainMenu', 'template': 'AppBundle:Menu:knp_menu.html.twig'}) }}
拷贝文件:
/SRC /的appbundle /菜单的10
例Builder.php
<?php
namespace AppBundle\Menu;
use Knp\Menu\FactoryInterface;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;
class Builder implements ContainerAwareInterface
{
use ContainerAwareTrait;
public function mainMenu(FactoryInterface $factory, array $options)
{
$menu = $factory->createItem('root');
$menu->addChild('Main', array('route' => 'homepage'));
$menu->setChildrenAttribute('class', 'nav navbar-nav');
// create another menu item
$menu->addChild('About', array('route' => 'About'));
$menu['About']->addChild('Contacts', array('route' => 'About'));
$menu['About']->addChild('Contacts1', array('route' => 'About'));
$menu['About']->setChildrenAttribute('class', 'dropdown-menu');
// ... add more children
return $menu;
}
}
