Zend framework: using BreadCrumbs with partial - zend-framework

Question

I have some trouble making a customized breadcrumb:
I my layout.phtml I have:
$container = new Zend_Navigation();
$this->navigation($container);
$container->addPage(
array(
'label' => 'Dashboard',
'module' => 'default',
'controller' => 'dashboard',
'action' => 'index',
'pages' =>
array(
array(
'label' => 'Create Order',
'module' => 'default',
'controller' => 'createorder',
'action' => 'index'
),
array(
'label' => 'Query',
'module' => 'default',
'controller' => 'query',
'action' => 'index',
'pages' => array(
array(
'label' => 'View Order',
'module' => 'default',
'controller' => 'order',
'action' => 'vieworder'
)
)
),
array(
'label' => 'Administration',
'module' => 'default',
'controller' => 'admin',
'action' => 'index',
'pages' =>
array(
array(
'label' => 'News and Announcements',
'module' => 'default',
'controller' => 'admin',
'action' => 'addnews',
'pages' => array(
array(
'label' => 'Edit News and Announcements',
'module' => 'default',
'controller' => 'admin',
'action' => 'editnews'
)
)
)
)
)
)
)
);
The next line is:
echo $this->navigation()->breadcrumbs()->setPartial(array('BreadCrumb.phtml','default'));
The BreadCrumb.phtml is called well, but I don't know how to make an ul-li menu in my BreadCrumb.phtml. How do I get the navigation I'm actually in?
Thanks in advance for any help. Andrea

Answer 1

To do so, your BreadCrumb.phtml should look like this:
<?php
if (null === $this->container) {
$this->container = $this->breadcrumbs()->getContainer();
}
// find deepest active
if (!$active = $this->breadcrumbs()->findActive($this->container)) {
return '';
}
$active = $active['page'];
// put the deepest active page last in breadcrumbs
if ($this->breadcrumbs()->getLinkLast()) {
$html = ' <li>' . $this->breadcrumbs()->htmlify($active) . '</li>' . PHP_EOL;
} else {
$html = $active->getLabel();
if ($this->breadcrumbs()->getUseTranslator() && $t = $this->breadcrumbs()->getTranslator()) {
$html = $t->translate($html);
}
$html = ' <li>' . $this->escape($html) . '</li>' . PHP_EOL;
}
// walk back to root
while (($parent = $active->getParent()) != null) {
if ($parent instanceof Zend_Navigation_Page) {
// prepend crumb to html
$html = ' <li>' . $this->breadcrumbs()->htmlify($parent) . '</li>' . PHP_EOL . $html;
}
if ($parent === $this->container) {
// at the root of the given container
break;
}
$active = $parent;
}
echo strlen($html) ? $this->breadcrumbs()->getIndent() . '<ul id="breadcrumbs">' . PHP_EOL
. $html . '</ul>' . PHP_EOL : '';
?>
Then you will get something like this:
<ul id="breadcrumbs">
<li>Home</li>
<li>Articles</li>
<li>Shop</li>
<li>Last link</li>
</ul>

Answer 2

Inside the view script, the zend navigation container is retrievable via $this->container. The container is iterable, so you can walk through it with a simple foreach loop (e.g. foreach($this->container as $page)

Answer 3

I've found simple solution for render breadcrumbs wrapped in ul-li menu.
You can place this code in your breadcrumbs.phtml:
<?php $breadcrumbs = $this->navigation()->breadcrumbs()->setMinDepth(0); ?>
<?php $items = array_filter(explode($breadcrumbs->getSeparator(), $breadcrumbs->render())); ?>
<?php if ($items) : ?>
<ul class="breadcrumbs">
<?php foreach ($items as $item) : ?>
<li><?= $item ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
