php - 导航面包屑不在 zend 框架 2 中呈现

Question

我是 zend 框架的新手，我根据此链接（http://zf2.readthedocs.org/en/latest/tutorials/tutorial.navigation.html）进行了操作，但视图或布局中未显示面包屑。以下是我已经实现的代码。指导我做错了什么？

在 module.config.php 中，

return array(
     ........
     'router' => array(
        'routes' => array(
            'admin' => array(
                'type'    => 'segment',
                'options' => array(
                    'route'    => '/admin[/][:action][/:id]',
                    'constraints' => array(
                        'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        'id'     => '[0-9]+',
                    ),
                    'defaults' => array(
                        'controller' => 'Admin\Controller\Admin',
                        'action'     => 'index',
                    ),
                ),
                'may_terminate' => true,
                 'child_routes' => array(
                    'settings' => array(
                        'type'    => 'Segment',
                        'may_terminate' => true,
                        'options' => array(
                            'route'    => '/general[/][:action][/][:id]',
                            'constraints' => array(

                                'id'     => '[0-9]+',
                            ),
                            'defaults' => array(
                                'controller' => 'Admin\Controller\Settings\General',
                                'action'     => 'index',
                            ),
                        ),
                    ),
                ),
            ),
            'dashboard' => array(

                        'id'     => '[0-9]+',
                    ),
                    'defaults' => array(

                    ),

    ),

                        'route' => 'admin/settings/general/',
                        'action' => 'web',
                    ),
                ),
            ),
        ),
    ),
'view_manager' => array(
        'template_map' => array(
            'layout/sidemenu'           => __DIR__ . '/../view/admin/common/sidemenu.phtml',

            'navigation' => 'Zend\Navigation\Service\DefaultNavigationFactory',  
        ),
    ),
    ......
);

在 layout.phtml 中

$this->navigation('navigation')
               ->breadcrumbs()
               ->setMinDepth(0)
               ->setPartial('layout/breadcrumbs');

请将路由条件“admin/dashboard”更改为“admin/default”。如果它仍然不起作用，那么您可以通过在 module.php 中实现以下代码来捕获matchedRoute：

/* put these lines on top after namespace */

use Zend\Mvc\ModuleRouteListener;

use Zend\Mvc\MvcEvent;

/* put these functions in class */

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $eventManager->attach('route', array($this, 'onRouteFinish'), -100);
}

public function onRouteFinish($e)
{
     $matches    = $e->getRouteMatch();
     $controller = $matches->getParam('controller');
     var_dump($matches);die();
}

结果，请检查["matchedRouteName":protected]module.config.php 中的值并相应地更改您的路由条件。祝你好运..！！
