Zend2 navigation - php

Question

I would like to make navigation buttons in my view, for example index.phtml but it's not working. I did know how to do it in Zend1 but in Zend2 I have a problem. My code looks like this (file index.phtml):
$container = new \Zend\Navigation\Navigation($tableActions);
var_dump($container);
echo '<div class="table-column">';
echo $this->navigation($container)->menu();
echo '</div>';
Variable $tableAction looks like this:
public $tableActions = array(
array(
'label' => 'On/Off',
'module' => 'import',
'controller' => 'import',
'action' => 'setstatus',
'params' => array('id' => null),
),
);
I did not get any error, just whole site die on this line. var_dump returns object(Zend\Navigation\Navigation) so it's fine so far. Problem is, how to show it...

Answer 1

The navigation pages have dependencies which aren't being met by just creating a new container class in a view. The Mvc page needs a RouteStackInterface (Router) instance and a RouteMatch instance. Similarly Uri pages need the current Request instance.
You can see this clearly if you take a look at the Zend\Navigation\Service\AbstractNavigationFactory and its preparePages and injectComponents methods.
The view is not the right place to be instantiating menus, instead put the menu configuration spec in your module.config.php...
<?php
return array(
'navigation' => array(
'table_actions' => array(
array(
'label' => 'On/Off',
'module' => 'import',
'controller' => 'import',
'action' => 'setstatus',
'params' => array('id' => null),
),
),
),
);
Write a factory extending the AbstractNavigationFactory class and implement the getName() method which returns the name of your menu spec key (table_actions in this example)
<?php
namespace Application\Navigation\Service;
use Zend\Navigation\Service\AbstractNavigationFactory;
class TableActionsFactory extends AbstractNavigationFactory
{
/**
* #return string
*/
protected function getName()
{
return 'table_actions';
}
}
Map the factory to a service name in the service_manager spec of module.config.php ...
<?php
return array(
'navigation' => array(// as above ... )
'service_manager' => array(
'factories' => array(
'TableActionsMenu' => 'Application\Navigation\Service\TableActionsFactory',
),
),
);
Now you can call the view helper using the service name TableActionsMenu you just mapped
<div class="table-column">
<?php echo $this->navigation('TableActionsMenu')->menu(); ?>
</div>
Finally, if, as I suspect, you need to change an attribute of the page depending on the view, you can do that too, navigation containers have find* methods which can be accessed from the navigation helper and used to retrieve pages.
Here's an example looking for the page with a matching page label, then changing it before rendering (obviously not an ideal search param, but it gives you the idea)
$page = $this->navigation('TableActionsMenu')->findOneByLabel('On/Off');
$page->setLabel('Off/On');
// and then render ...
echo $this->navigation('TableActionsMenu')->menu();
