Editable Breadcrumb for Dynamic Pages - zend-framework

Question

Looking for a better Breadcrumb solution for a Zend Framework project.
Currently I have a navigation.xml like
<?xml version="1.0" encoding="UTF-8"?>
<configdata>
<nav>
<home>
<label>Home</label>
<module>default</module>
<controller>index</controller>
<action>index</action>
<pages>
<countryurl>
<label>Spain</label>
<module>default</module>
<controller>country</controller>
<action>index</action>
<route>country_url</route>
<params>
<country>spain</country>
</params>
<pages>
<provinceurl>
<label>Madrid</label>
<module>default</module>
<controller>country</controller>
<action>province</action>
<route>province_url</route>
<params>
<country>spain</country>
<province>madrid</province>
</params>
<pages>
<cityurl>
<label>City</label>
<module>default</module>
<controller>country</controller>
<action>city</action>
<route>city_url</route>
<params>
<country>spain</country>
<province>madrid</province>
<city>madrid</city>
</params>
<pages>
<producturl>
<label>Product</label>
<module>default</module>
<controller>country</controller>
<action>product</action>
<route>product_url</route>
<params>
<country>spain</country>
<province>madrid</province>
<city>madrid</city>
<product>product</product>
</params>
</producturl>
</pages>
</cityurl>
</pages>
</provinceurl>
</pages>
</countryurl>
</pages>
</home>
</nav>
</configdata>
and routes like
$router->addRoute(
'product_url',
new Zend_Controller_Router_Route(':lang/:country/:province/:city/:product', array(
'controller' => 'country',
'action' => 'product'
))
);
$router->addRoute(
'city_url',
new Zend_Controller_Router_Route(':lang/:country/:province/:city', array(
'controller' => 'country',
'action' => 'city'
))
);
$router->addRoute(
'province_url',
new Zend_Controller_Router_Route(':lang/:country/:province', array(
'controller' => 'country',
'action' => 'province'
))
);
$router->addRoute(
'country_url',
new Zend_Controller_Router_Route(':lang/:country', array(
'controller' => 'country',
'action' => 'index'
))
);
I am facing some issues / looking for some suggestions . Creating the Breadcrumbs with the help of Zend_Navigation
$config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml', 'nav');
$container = new Zend_Navigation($config);
$view->navigation($container);
1 ) The request for http://example.com/en/spain/madrid/madrid/product shows the breadcrumb, with the help of
$this->navigation()
->breadcrumbs()
->setMinDepth(0)
->setLinkLast(true)
->setSeparator(" > ");
as Home > Spain > Madrid > City > Product
But the links pointing at Spain , Madrid , City all are to http://example.com . Which should be http://example.com/en/spain , http://example.com/en/spain/madrid , http://example.com/en/spain/madrid/madrid respectively.
2 ) Currently when the request for http://example.com/en/spain
the breadcrumb will show Home >> Spain
<label>Spain</label>
<module>default</module>
<controller>country</controller>
<action>index</action>
<route>country_url</route>
<params>
<country>spain</country>
</params>
But you can see the param country differs according to country. So do we want to add the labels for all countries ?
http://example.com/en/spain
Home >> Spain
http://example.com/en/india
Home >> India
I have provinces , city and product coming along, any suggestions how I can build for it ?
Also this is a multilingual website, so how can we make the necessary changes to the label? I guess if we are using Zend_Translate it will make the necessary changes.

Answer 1

You can create your own page class that treats params beginning with : as dynamic. You can reference it in the nav configuration like
...
<countryurl>
<label>:country</label> <!-- dynamic -->
<module>default</module>
<controller>index</controller>
<action>index</action>
<route>country_url</route>
<type>DynamicNavPage</type> <!-- page classname -->
<params>
<country>:country</country> <!-- dynamic -->
</params>
<pages>
...
and for example
<?php
class DynamicNavPage extends Zend_Navigation_Page_Mvc {
/**
* Params with ":" are read from request
*
* #param array $params
* #return Zend_Navigation_Page_Mvc
*/
public function setParams(array $params = null) {
$requestParams = Zend_Controller_Front::getInstance()
->getRequest()->getParams();
//searching for dynamic params (begining with :)
foreach ($params as $paramKey => $param) {
if (substr($param, 0, 1) == ':' &&
array_key_exists(substr($param, 1), $requestParams)) {
$params[$paramKey] = $requestParams[substr($param, 1)];
}
}
return parent::setParams($params);
}
/**
* If label begining with : manipulate (for example with Zend_Tanslate)
*/
public function setLabel($label) {
if (substr($label, 0, 1) == ':') {
//label modifications go here
//as an example reading it from page params and capitalizing
//can use Zend_Translate here
$requestParams = Zend_Controller_Front::getInstance()
->getRequest()->getParams();
$labelParamKey = substr($label, 1);
if (array_key_exists($labelParamKey, $requestParams)) {
$label = ucfirst($requestParams[$labelParamKey]);
}
}
return parent::setLabel($label);
}
}
