我正在尝试实现Zend_导航——创建菜单和面包屑

在引导文件中

...
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap {

    protected $_config;
    protected $_layout;

    protected function _initConfig() {
        $this->_config = new Zend_Config_Ini(APPLICATION_PATH . '/configs/application.ini'); 
        Zend_Registry::set("config", $this->_config);
        if ($this->_config->debug) {
            error_reporting(E_ALL | E_STRICT);
            ini_set('display_errors', 'on');
        }
        $request = new Zend_Controller_Request_Http();
        $uri = $request->getRequestUri(); 
        if (preg_match("/admin/", $uri)) {
            //echo $this->_config->layout->admin->layout; exit;
            $this->_layout = Zend_Layout::startMvc(
                            array(
                                'layoutPath' => $this->_config->layout->layoutPath,
                                'layout' => $this->_config->layout->admin->layout
                            )
            );
        } else { 
            $this->_layout = Zend_Layout::startMvc(
                            array(
                                'layoutPath' => $this->_config->layout->layoutPath,
                                'layout' => $this->_config->layout->layout)
            );
            //echo $this->_view = $this->_layout->getView(); exit;
        }
    }
    /**
     * used for handling top-level navigation
     * @return Zend_Navigation
      */
    protected function _initNavigation()
    {
            $view = $this->_layout->getView();   
           /*
            $this->bootstrap('layout');
            $layout = $this->getResource('layout');
            $view = $layout->getView();
            */
            $config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml','nav');

            $container = new Zend_Navigation($config);

            $view->navigation($container);
    }   
...
下面是application/config文件夹下的navigation.xml

<?xml version="1.0" encoding="UTF-8"?>
<configdata>
    <nav>
        <home>
            <label>Home</label>
            <uri>/</uri>

            <pages>
                <index>
                    <label>Home</label>
                    <uri>/index/index</uri>     
                </index>
                <index>
                    <label>Product</label>
                    <uri>/index/product</uri>       
                </index>

            </pages>        
        </home>
    </nav>
</configdata>

在布局文件中

...
            <div class="breadcrumbs">
            <?= $this->navigation()->breadcrumbs()->setMinDepth(0)->setLinkLast(true)->setSeparator(" : "); ?>
        </div>
...
。。。

当我运行该站点时,我得到了以下错误:

我在stackoverflow和google上搜索了一些解决方案,但没有找到。我在这方面做错了什么?请注意

我已经运行了您的代码。错误在配置中。您有两个同名的兄弟姐妹,Zend_Config_Xml将其添加到此表单

array
  'label' => string 'Home' (length=4)
  'uri' => string '/' (length=1)
  'pages' => 
    array
      'index' => 
        array
          0 => 
            array
              'label' => string 'Home' (length=4)
              'uri' => string '/index/index' (length=12)
          1 => 
            array
              'label' => string 'Product' (length=7)
              'uri' => string '/index/product' (length=14)
当您查看Zend_Mvc_页面第235行时,您可以了解引发异常的原因

        $hasUri = isset($options['uri']);
        $hasMvc = isset($options['action']) || isset($options['controller']) ||
                  isset($options['module']) || isset($options['route']);

        if ($hasMvc) {
            require_once 'Zend/Navigation/Page/Mvc.php';
            return new Zend_Navigation_Page_Mvc($options);
        } elseif ($hasUri) {
            require_once 'Zend/Navigation/Page/Uri.php';
            return new Zend_Navigation_Page_Uri($options);
        } else {
            require_once 'Zend/Navigation/Exception.php';
            throw new Zend_Navigation_Exception(
                'Invalid argument: Unable to determine class to instantiate');
        }

最后,解决方案是更改第二个同级名称。

在“有两个节点”下,尝试重命名them@Ashley谢谢,现在错误已经修复
