Can someone please help me out, I'm totally stuck! I don't know how to add a class name to <li> tag in Zend navigation XML
This is my XML
<configdata>
<nav>
<home>
<label>Home </label>
<uri>/</uri>
</home>
<request>
<label>Quotes </label>
<uri>/quote</uri>
</request>
<work>
<label>How It Works</label>
<uri>/how-it-works</uri>
</work>
<information>
<label>Informations </label>
<uri>/informations</uri>
</information>
<directory>
<class> last </class>
<label>Directory </label>
<uri>/directory</uri>
</directory>
</nav>
</configdata>
When I add <class>last</class> this is what i get:
<li>
<a class="last" href="/directory">Directory </a>
</li>
Currently I'm getting <a class="last"> but I need <li class="last">
Thanks so much in advance! Cheers
I think that the best way to put css classes into li elements would be to write your own navigation menu helper, called for example My_View_Helper_NavigationMenu that extends original Zend_View_Helper_Navigation_Menu class. For this reason I prepared an example of such a helper that overloads _renderMenu() method. The code of the method seems long, but this is because original code is long. There are only few new/modified lines in overloaded _renderMenu():
File: APPLICATION_PATH/views/helpers/NavigationMenu.php
class My_View_Helper_NavigationMenu extends Zend_View_Helper_Navigation_Menu {
/**
* Renders a normal menu (called from {@link renderMenu()})
*
* @param Zend_Navigation_Container $container container to render
* @param string $ulClass CSS class for first UL
* @param string $indent initial indentation
* @param int|null $minDepth minimum depth
* @param int|null $maxDepth maximum depth
* @param bool $onlyActive render only active branch?
* @return string
*/
protected function _renderMenu(Zend_Navigation_Container $container,
$ulClass,
$indent,
$minDepth,
$maxDepth,
$onlyActive)
{
$html = '';
// find deepest active
if ($found = $this->findActive($container, $minDepth, $maxDepth)) {
$foundPage = $found['page'];
$foundDepth = $found['depth'];
} else {
$foundPage = null;
}
// create iterator
$iterator = new RecursiveIteratorIterator($container,
RecursiveIteratorIterator::SELF_FIRST);
if (is_int($maxDepth)) {
$iterator->setMaxDepth($maxDepth);
}
// iterate container
$prevDepth = -1;
foreach ($iterator as $page) {
$depth = $iterator->getDepth();
$isActive = $page->isActive(true);
if ($depth < $minDepth || !$this->accept($page)) {
// page is below minDepth or not accepted by acl/visibilty
continue;
} else if ($onlyActive && !$isActive) {
// page is not active itself, but might be in the active branch
$accept = false;
if ($foundPage) {
if ($foundPage->hasPage($page)) {
// accept if page is a direct child of the active page
$accept = true;
} else if ($foundPage->getParent()->hasPage($page)) {
// page is a sibling of the active page...
if (!$foundPage->hasPages() ||
is_int($maxDepth) && $foundDepth + 1 > $maxDepth) {
// accept if active page has no children, or the
// children are too deep to be rendered
$accept = true;
}
}
}
if (!$accept) {
continue;
}
}
// make sure indentation is correct
$depth -= $minDepth;
$myIndent = $indent . str_repeat(' ', $depth);
if ($depth > $prevDepth) {
// start new ul tag
if ($ulClass && $depth == 0) {
$ulClass = ' class="' . $ulClass . '"';
} else {
$ulClass = '';
}
$html .= $myIndent . '<ul' . $ulClass . '>' . self::EOL;
} else if ($prevDepth > $depth) {
// close li/ul tags until we're at current depth
for ($i = $prevDepth; $i > $depth; $i--) {
$ind = $indent . str_repeat(' ', $i);
$html .= $ind . ' </li>' . self::EOL;
$html .= $ind . '</ul>' . self::EOL;
}
// close previous li tag
$html .= $myIndent . ' </li>' . self::EOL;
} else {
// close previous li tag
$html .= $myIndent . ' </li>' . self::EOL;
}
// ***************** THESE ARE NEW LINES *************** //
$liMyClass = $page->get('liclass') ? $page->liclass : '' ;
if ($isActive) {
$liClass = " class=\"active $liMyClass\" ";
} else {
$liClass = $liMyClass ? " class=\"$liMyClass\" ":'';
}
// ***************** END OF NEW STUFF *************** //
// render li tag and page (ORGINAL LINE REMOVED)
//$liClass = $isActive ? ' class="active "' : '';
$html .= $myIndent . ' <li' . $liClass . '>' . self::EOL
. $myIndent . ' ' . $this->htmlify($page) . self::EOL;
// store as previous depth for next iteration
$prevDepth = $depth;
}
if ($html) {
// done iterating container; close open ul/li tags
for ($i = $prevDepth+1; $i > 0; $i--) {
$myIndent = $indent . str_repeat(' ', $i-1);
$html .= $myIndent . ' </li>' . self::EOL
. $myIndent . '</ul>' . self::EOL;
}
$html = rtrim($html, self::EOL);
}
return $html;
}
}
In your layout.phtml you need to indicate to the navigation view helper to use this new class. You can do this as follows:
<?php $this->navigation()->setDefaultProxy('navigationMenu'); ?>;
Finally in your navigation.xml you could define a class for a li element using liclass tag (you can use whatever name you want for this tag):
<directory>
<class> last </class>
<label>Directory </label>
<uri>/directory</uri>
<liclass>someclass</liclass>
</directory>
Hopefully this will be helpful to you. Ideally, I should have named the new class My_View_Helper_Navigation_Menu (located in APPLICATION_PATH/views/helpers/Navigation/Menu.php). However, I could not make Zend plugin loaders to load it and I went with My_View_Helper_NavigationMenu.
