zend navigation single level menu using xml file

Question

With zend framework how do i create a single level menu?

I followed a tutorial and the person created a two level dropdown menu. I want to just remove home. I've modified the navigation.xml file a couple times and it caused a fatal error.

What xml markup do i need to promote the children of home as the parent level menus? As in i don't need a home button at all.

Desired outcome:

• who
• why
• what
• speaker
• resources

Current outcome:

• home

  • who

  • what

  • when

  • why

Current navigation.xml file:

<?xml version="1.0" encoding="UTF-8" ?>
<configdata>
  <nav>
    <home>
      <label>Home</label>
      <controller>page</controller>
      <action>index</action>
      <module>default</module>
      <pages>
        <why>
          <label>why</label>
          <controller>page</controller>
          <action>why</action>
          <module>default</module>
        </why>
        <who>
          <label>who</label>
          <controller>page</controller>
          <action>who</action>
        </who>
        <resources>
          <label>resources</label>
          <controller>page</controller>
          <action>resources</action>
        </resources>
        <signin>
          <label>sign in</label>
          <controller>account</controller>
          <action>login</action>
          <module>default</module>
        </signin>
      </pages>
    </home>
  </nav>

...

application/Bootstrap.php:

<?php function _initViewHelpers() {
   $this->bootstrap('layout);
   // ... Skipping to relevant part
    $navContainerConfig = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml', 'nav');
    $navContainer = new Zend_Navigation($navContainerConfig);
    $view->navigation($navContainer);
} ?>

layouts/default.phtml

<div class="navigation"><?php print $this->navigation(); ?></div>

Answer 2

What about setMaxDepth() and setMinDepth()? You can set how deep you want your menu to be rendered:

<?= $this->navigation()->menu()
                       ->setMinDepth(1)
                       ->setMaxDepth(2)
                       ->render() . PHP_EOL; ?>

Also, you can find more information about the navigation view helper in the official manual. These information are often more relevant than the ones you can find in tutorials.

Answer 3

you should be able to just adjust your container to display only the links you want displayed. In this case you would just remove the Home elements from your xml file.

<?xml version="1.0" encoding="UTF-8" ?>
<configdata>
  <nav>
      <pages>
        <why>
          <label>why</label>
          <controller>page</controller>
          <action>why</action>
          <module>default</module>
        </why>
        <who>
          <label>who</label>
          <controller>page</controller>
          <action>who</action>
        </who>
        <resources>
          <label>resources</label>
          <controller>page</controller>
          <action>resources</action>
        </resources>
        <signin>
          <label>sign in</label>
          <controller>account</controller>
          <action>login</action>
          <module>default</module>
        </signin>
      </pages>
  </nav>

Answer 4

When you remove the Home menu from the XML file , you get an exception

Zend_Navigation_Exception: Invalid argument: Unable to determine class to instantiate in C:\www\project\library\Zend\Navigation\Page.php on line 235
