Question

嗨我想在我的zend框架应用程序中使用breadcrumb

我在configs文件夹中创建了navigation.xml，其中application.ini是。

并在bootstarp中添加了以下代码

protected function _initNavigation()
{
    $this->bootstrap('layout');
    $layout = $this->getResource('layout');
    $view = $layout->getView();
    $config = new Zend_Config_Xml(APPLICATION_PATH.'/configs/navigation.xml');

    $navigation = new Zend_Navigation($config);
    $view->navigation($navigation);
}

在布局中我添加了以下代码

    <div id="menu">
        <?php echo $this->navigation()->menu(); ?>
    </div>
    <div id="breadcrumbs">
        You are in: <?php echo $this->navigation()->breadcrumbs()->setLinkLast(false)->setMinDepth(0)->render(); ?>
    </div>

它不起作用，给出了错误

这是我的xml文件

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <nav>
        <dashboard>
            <label>dashboard</label>

                    </pages>
                </occupancydenomination>
            </pages>        
        </dashboard>
    </nav>
</config>

我不确定错误是什么。请帮帮我................

Answer 1

错误是由配置文件引起的。

您没有为导航容器提供足够的参数来确定正确的网页类型Zend_Navigation_Page_Mvc或Zend_Navigation_Page_Uri。

另外，你知道有一个navigation resource plugin，对吧？

<强>更新

摆脱<nav>包装元素。它试图将其解释为一个页面。

那或遵循example并正确指定配置部分

$config = new Zend_Config_Xml('/path/to/navigation.xml', 'nav');
$container = new Zend_Navigation($config);

尝试在zend框架中使用breadcrumb时在bootstrap中出错
