嘿我想在我的標題，我有全局菜單，然後頁面菜單，然後breadcrumbs佈局。要做到這一點，我主要從這個答案中拿走：Rendering Active Branch of Zend Navigation Without Top LevelZend View Helper導航刪除活動分支，所以麪包屑不會顯示
這很好，除了活動分支從註冊的Zend_Navigation_Container中移除。
這是我要做的事：
<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>
結果是麪包屑是不存在的：
<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>
有源分支被切斷，以頂層，這裏是其切割前的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
...
此輸出整個容器：
...
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
)
)
...
這是我後添加頁面到新的容器：
...
$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
...
輸出：
...
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
)
)
...
我不知道爲什麼會這樣，因爲我創造了新的容器並添加頁面，似乎他們正從Zend_Registry中Zend_Navigation關鍵字的容器中移除。
很快，如果我註釋掉該行的麪包屑再次工作和容器保持完好，但我失去了過程的二級菜單：
...
$subMenu = new Zend_Navigation();
//This is the line that removes the active branch
//$subMenu->setPages($activeBranch);
//Render 2nd level menu
...
輸出：
...
<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>
...
