我正在尝试实现Zend_Navigation - 通过此tutorial
创建菜单和面包屑在Bootstrap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);
}
...
以下是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>
...
当我运行该网站时,我收到以下错误,
致命错误:未捕获异常'Zend_Navigation_Exception' 消息'无效参数:无法确定要实例化的类' 在C:\ xampp \ htdocs \ enit \ library \ Zend \ Navigation \ Page.php:235 Stack 追踪:#0 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ Container.php(117): Zend_Navigation_Page :: factory(数组)#1 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ Container.php(164): Zend_Navigation_Container-&gt; addPage(Array)#2 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ Container.php(179): Zend_Navigation_Container-&gt; addPages(数组)#3 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ page.php文件(852): Zend_Navigation_Container-&gt; setPages(Array)#4 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ page.php文件(295): Zend_Navigation_Page-&gt; set('pages',Array)#5 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ page.php文件(250): Zend_Navigation_Page-&gt; setOptions(Array)#6 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ page.php文件(232): Zend_Navigation_Page-&gt; __ construct(Array)#7 C:\ XAMPP \ htdocs中\ ENIT \库\ Zend的\导航\ Container.php(117): Zend_Navigation_P in 第235行的C:\ xampp \ htdocs \ enit \ library \ Zend \ Navigation \ Page.php
我搜索了stackoverflow以及谷歌的一些解决方案,但我找不到它。我做错了什么?请提供建议
答案 0 :(得分:1)
我已经运行了你的代码。 Bug在配置中。你有两个同名的兄弟姐妹,Zend_Config_Xml将它归结为这种形式
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_Page第235行时,您可以找出抛出异常的原因。
$hasUri = isset($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');
}
所以最后解决方案是改变第二个兄弟姐妹的名字。
