Zend_Navigation_Page_Mvc and Fragment Identifiers

Question

I use Zend_Navigation on my site. Most of the items are Zend_Navigation_Page_Mvc and NOT Zend_Navigation_Page_Uri. I know that I can easily add a fragment identifier to a Zend_Navigation_Page_Uri item, but that's not the elegant solution I'm looking for. There are a couple of solutions on this post, but they extend the URL helper and don't affect navigation.

I already use a sub-classed Zend_View_Helper_Navigation_Menu to render the menus. Maybe there's a way to accomplish this with the htmlify() function?

Answer 1

I ended up adding a property called fragment to the page array passed into Zend_Navigation and then checking for it in my sub-classed Zend_View_Helper_Navigation_Menu::htmlify(). Here is my htmlify() code:

/**
 * Returns an HTML string containing an 'a' element for the given page if
 * the page's href is not empty, and a 'span' element if it is empty
 *
 * Overrides {@link Zend_View_Helper_Navigation_Abstract::htmlify()}.
 *
 * @param  Zend_Navigation_Page $page  page to generate HTML for
 * @return string                      HTML string for the given page
 */
public function htmlify(Zend_Navigation_Page $page)
{
    // get label and title for translating
    $label = $page->getLabel();
    $title = $page->getTitle();

    // translate label and title?
    if ($this->getUseTranslator() && $t = $this->getTranslator()) {
        if (is_string($label) && !empty($label)) {
            $label = $t->translate($label);
        }
        if (is_string($title) && !empty($title)) {
            $title = $t->translate($title);
        }
    }

    // get attribs for element
    $attribs = array(
        'id'     => $page->getId(),
        'title'  => $title,
        'class'  => $page->getClass()
    );

    // does page have a href?
    if ($href = $page->getHref()) {
        $element = 'a';
        $attribs['href'] = $href;
        $attribs['target'] = $page->getTarget();
        // fragment identifier
        if (0 < strlen($fragment = $page->get('fragment'))) {
            $attribs['href'] .= '#' . $fragment;
        }
    } else {
        $element = 'span';
    }

    return '<' . $element . $this->_htmlAttribs($attribs) . '><span>'
         . $this->view->escape($label)
         . '</span></' . $element . '>';
}
