Zend navigation breadcrumbs

Question

I have an xml navigation system with article as an element. The breadcrumb works as far as my article page where i display the list of articles with their title (as a link) and a teaser paragraph. The page where i display the full article does not show any breadcrumb navigation.

I know i'm doing something wrong but since i am new to zend i can't figure out where.

I would be grateful if someone could point me towards the right direction.

The XML Navigation:

<?xml version="1.0" encoding="UTF-8"?>
  <configdata>
  <nav>
    <home>
        <label>Home</label>
        <controller>index</controller>
        <action>index</action>
        <pages>

            <about>
                <label>About</label>
                <controller>index</controller>
                <action>about</action>

            </about>
        <board>
            <label>Executive Committee</label>
            <controller>index</controller>
            <action>committee</action>
        </board>
        <events>
                <label>Events</label>
                <controller>index</controller>
                <action>events</action>
        </events>


        <member>
                <label>CNFS Members</label>
                <controller>index</controller>
                <action>member</action>

            </member>
            <news>
                <label>Blog</label>
                <controller>blog</controller>
                <action>index</action>

            </news>
            <contact>
                <label>Contact</label>
                <controller>index</controller>
                <action>contact</action>
        </contact>
        </pages>
    </home>
</nav>
</configdata>

This is the function in the bootstrap file for navigation.

<?php
   protected function _initViewNavigation(){
     $this->bootstrap('layout');
     $layout = $this->getResource('layout');
     $view = $layout->getView();
     $config = new Zend_Config_Xml(APPLICATION_PATH.'/configs/navigation.xml','nav');
     $navigation = new Zend_Navigation($config);
     $view->navigation($navigation);
    }
    ?>

This is how i display the breadcrumbs in the view:

    <?php echo  'Your are here: ' . $this->navigation()->breadcrumbs() ->setMinDepth(0)->setLinkLast(false)->setSeparator("   /  ");?>

From your xml, i guess that your articles list is at /blog, and an single article at /blog/article/'articleId' or something similar.

Your "news" section in your navigation map defines an action, "index" but to display an article you use an other action, that's why this node isn't matched anymore.

I guess you would like the current article's title to show at the end of your breadcrumb, and to do that you must append a custom page as a child of the "news" node, and setting it as 'active' :

public function articleAction(){
    //get your article
    $article = ....


    $page = new Zend_Navigation_Page_Mvc(array(  
            'label'         => $article->getTitle(),  
            'controller'    => 'blog',  
            'action'        => 'article',  
            'params'        => array(
                'id' => $article->getId() // replace with the param name + value that you actually use in your url
                 )
            )
       );
    $page->setActive(true);

    $this->view->_helper->navigation()->getContainer()->findOneBy('controller','blog')->addPage($page);

I wrote this code by memory without testing, so if it doesn't work as expected just tell me, i'll test and update this answer
