Passing url parameters to Zend_Navigation using an XML-file - php

Question

I am using Zend Framework 1.10.8.
I want to create a breadcrumb section in my layout.phtml. There are some links in my menu that have dynamic url parameters like http://mydomain.com/editor/edit/id/42
I try to figure out how to pass id=XXX to Zend_Navigation, while XXX comes from the database and is different in every request.
One solution I found so far is adding a property e.g. params_id to my xml declaration:
in configs/navigation.xml
<pages>
<editor>
<label>Editor</label>
<controller>editor</controller>
<action>edit</action>
<params_id>id</params_id>
<route>default</route>
</editor>
</pages>
and in the controller looping through the pages and dynamically adding my parameter id = 42 (while 42 would be retrieved from the request object in the final version)
$pages = $this->view->navigation()->getContainer()->findAllBy('params_id','id');
foreach ($pages as &$page) {
$page->setParams(array(
'id' => 42,
'something_else' => 667
));
}
As adding dynamic url parameters seems such a basic requirement for Zend_Navigation I am quite sure that my solution is too complicate, too expensive and there must be a much simplier solution "out of the box".

Answer 1

It is very simple. Just write in your XML
<pages>
<editor>
<label>Editor</label>
<controller>editor</controller>
<action>edit</action>
<params>
<id>42</id>
<someting_else>667</something_else>
</params>
<route>default</route>
</editor>
</pages>
Here is example to do it dynamically based on database data
First define Navigation loading plugin. Name the file Navigation.php and place it in application/plugins/ directory. Here's an example of such plugin:
class Plugin_Navigation extends Zend_Controller_Plugin_Abstract
{
function preDispatch(Zend_Controller_Request_Abstract $request)
{
$view = Zend_Controller_Action_HelperBroker::getExistingHelper('ViewRenderer')->view;
//load initial navigation from XML
$config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml','nav');
$container = new Zend_Navigation($config);
//get root page
$rootPage = $container->findOneBy('sth', 'value');
//get database data
$data = Model_Sth::getData();
foreach ($data as $row) {
$rootPage->addPage(new Zend_Navigation_Page_Mvc(array(
'module' => 'default',
'controller' => 'examplecontroller',
'action' => 'exampleaction',
'route' => 'exampleroute',
'label' => $row['some_field'],
'params' => array(
'param1' => $row['param1'],
'param2' => $row['param1']
)
)));
}
//pass container to view
$view->navigation($container);
}
}
Then in you Bootstrap init this plugin
protected function _initNavigation() {
Zend_Controller_Front::getInstance()->registerPlugin(new Plugin_Navigation());
}

An update: I finally ended up throwing away the xml file. What I do now:
I wrote a plugin (see Daimon's approach)
in this plugin I configure my navigation structure as an array, the
dynamic parameters are retrieved from Zend_Request
then I init the navigation using this array
