嘿，我想在我的标题中有一个布局，我有全局菜单，然后是页面菜单，然后是面包屑。为此，我主要从这个答案中拿走了：在没有顶级的情况下渲染Zend导航的活动分支
这很好用，除了活动分支从注册的Zend_Navigation_Container中删除。
我是这样做的：
<nav>
<?php
//Create top level menu
echo $this->navigation()->menu()
->setUlClass('main')
->setMaxDepth(0)
->setIndent(4)
. PHP_EOL;
//Set to get the whole active branch
$this->navigation()
->setMinDepth(0)
->setMaxDepth(0);
//Retrive the active branch
$activeBranchTopLvl =
$this->navigation()->findActive(
$this->navigation()->getContainer());
//Get the 2nd level pages for the active page
$activeBranch = $activeBranchTopLvl['page']->getPages();
$subMenu = new Zend_Navigation();
//This is the line that removes the active branch
$subMenu->setPages($activeBranch);
//Render 2nd level menu
echo $this->navigation()->menu($subMenu)
->setUlClass('sub')
. PHP_EOL;
//Set up for breadcrumbs
$this->navigation()->breadcrumbs()->setMinDepth(0);
$this->navigation()->setMaxDepth(null);
$this->navigation()->breadcrumbs()->setRenderInvisible(true);
?>
</nav>
<p id="breadcrumbs"><?php echo $this->navigation()->breadcrumbs()->render(); ?></p>
结果是痕迹导航不存在：
<nav>
<ul class="main">
<li class="active">
<a href="/auth">Auth</a>
</li>
</ul>
<ul class="sub">
<li class="active">
<a href="/auth/login">Log In</a>
</li>
<li>
<a href="/auth/logout">Log Out</a>
</li>
</ul>
</nav>
<p id="breadcrumbs"></p>
活动分支已被切断到顶层，这是其切割前的Zend_Navigation_Container：
...
$subMenu = new Zend_Navigation();
print_r($this->navigation()->getContainer()->toArray());
//This is the line that removes the active branch
$subMenu->setPages($activeBranch);
//Render 2nd level menu
...
这将输出整个容器：
...
Array
(
[0] => Array
(
[label] => Auth
[fragment] =>
[id] =>
[class] =>
[title] =>
[target] =>
[accesskey] =>
[rel] => Array
(
)
[rev] => Array
(
)
[order] =>
[resource] =>
[privilege] =>
[active] =>
[visible] => 1
[type] => Zend_Navigation_Page_Mvc
[pages] => Array
(
[0] => Array
(
[label] => Log In
[fragment] =>
[id] =>
[class] =>
[title] =>
[target] =>
[accesskey] =>
[rel] => Array
(
)
[rev] => Array
(
)
[order] =>
[resource] =>
[privilege] =>
[active] => 1
[visible] => 1
[type] => Zend_Navigation_Page_Mvc
[pages] => Array
(
)
[action] => login
[controller] => auth
[module] =>
[params] => Array
(
)
[route] =>
[reset_params] => 1
[encodeUrl] => 1
)
[1] => Array
(
[label] => Log Out
[fragment] =>
[id] =>
[class] =>
[title] =>
[target] =>
[accesskey] =>
[rel] => Array
(
)
[rev] => Array
(
)
[order] =>
[resource] =>
[privilege] =>
[active] =>
[visible] => 1
[type] => Zend_Navigation_Page_Mvc
[pages] => Array
(
)
[action] => logout
[controller] => auth
[module] =>
[params] => Array
(
)
[route] =>
[reset_params] => 1
[encodeUrl] => 1
)
)
[action] =>
[controller] => auth
[module] =>
[params] => Array
(
)
[route] =>
[reset_params] => 1
[encodeUrl] => 1
)
)
...
这是在我将页面添加到新容器之后：
...
$subMenu = new Zend_Navigation();
//This is the line that removes the active branch
$subMenu->setPages($activeBranch);
print_r($this->navigation()->getContainer()->toArray());
//Render 2nd level menu
...
输出：
...
Array
(
[0] => Array
(
[label] => Auth
[fragment] =>
[id] =>
[class] =>
[title] =>
[target] =>
[accesskey] =>
[rel] => Array
(
)
[rev] => Array
(
)
[order] =>
[resource] =>
[privilege] =>
[active] =>
[visible] => 1
[type] => Zend_Navigation_Page_Mvc
[pages] => Array
(
)
[action] =>
[controller] => auth
[module] =>
[params] => Array
(
)
[route] =>
[reset_params] => 1
[encodeUrl] => 1
)
)
...
我不知道为什么在创建新容器并向其中添加页面时会发生这种情况，似乎它们正在从我在密钥Zend_Navigation下的Zend_Registry容器中删除。
很快，如果我注释掉那行，面包屑会再次工作并且容器保持不变，但我当然会丢失第二级菜单：
...
$subMenu = new Zend_Navigation();
//This is the line that removes the active branch
//$subMenu->setPages($activeBranch);
//Render 2nd level menu
...
输出：
...
<nav>
<ul class="main">
<li class="active">
<a href="/auth">Auth</a>
</li>
</ul>
</nav>
<p id="breadcrumbs"><a href="/auth">Auth</a> > Log In</p>
...
虽然不漂亮，但我使用自定义函数来获取返回数组数组的Zend_Navigation_Page对象数组，然后保持主导航容器完好无损，以便菜单级别和面包屑都正常工作。
header.phtml：
<nav id="global">
<?php
//Create top level menu
echo $this->navigation()->menu()
->setUlClass('main navigation')
->setMaxDepth(0)
->setIndent(4)

//Set to get the top level active branch
$this->navigation()
->setMinDepth(0)
->setMaxDepth(0)
->setRenderInvisible(true)
;
//Retrive the active branch
$activeBranchTopLvl =
$this->navigation()->findActive(
$this->navigation()->getContainer());
//Get the 2nd level pages for the active page
$activeBranch = $activeBranchTopLvl['page']->getPages();
//create a function to make the array of page objects
//into an array of arrays, accomplished by modifying it as a reference
$arrayify = create_function(
'&$value, $key',
'$value = $value->toArray();'
);
//go through the array with the custom function
array_walk($activeBranch, $arrayify);
$subMenu = new Zend_Navigation();
//This is the line that removes the active branch
$subMenu->setPages($activeBranch);
//Render 2nd level menu
echo $this->navigation()->menu($subMenu)

->setRenderInvisible(false)
. PHP_EOL;
//Set up for breadcrumbs
$this->navigation()->breadcrumbs()->setMinDepth(0);
$this->navigation()->setMaxDepth(null);
$this->navigation()->breadcrumbs()->setRenderInvisible(true);
?>
</nav>
<p id="breadcrumbs"><?php echo $this->navigation()->breadcrumbs()->render(); ?></p>
