Zend\Navigation\Page\Mvc

MVC pages are defined using MVC parameters known from the Zend\Mvc component. An MVC page will use Zend\Mvc\Router\RouteStackInterface internally in the getHref() method to generate hrefs, and the isActive() method will compare the Zend\Mvc\Router\RouteMatch params with the page’s params to determine if the page is active.

Note

Starting in version 2.2.0, if you want to re-use any matched route parameters when generating a link, you can do so via the “useRouteMatch” flag. This is particularly useful when creating segment routes that include the currently selected language or locale as an initial segment, as it ensures the links generated all include the matched value.

MVC page options

Key	Type	Default	Description
action	String	NULL	Action name to use when generating href to the page.
controller	String	NULL	Controller name to use when generating href to the page.
params	Array	array()	User params to use when generating href to the page.
route	String	NULL	Route name to use when generating href to the page.
routeMatch	Zend\Mvc\Router\RouteMatch	NULL	RouteInterface matches used for routing parameters and testing validity.
useRouteMatch	Boolean	FALSE	If true, then getHref method will use the routeMatch parameters to assemble the URI
router	Zend\Mvc\Router\RouteStackInterface	NULL	Router for assembling URLs

Note

The URI returned is relative to the baseUrl in Zend\Mvc\Router\Http\TreeRouteStack. In the examples, the baseUrl is ‘/’ for simplicity.

getHref() generates the page URI

This example show that MVC pages use Zend\Mvc\Router\RouteStackInterface internally to generate URIs when calling $page->getHref().

// Create route
$route = Zend\Mvc\Router\Http\Segment::factory(array(
   'route'       => '/[:controller[/:action][/:id]]',
   'constraints' => array(
      'controller' => '[a-zA-Z][a-zA-Z0-9_-]+',
      'action'     => '[a-zA-Z][a-zA-Z0-9_-]+',
      'id'         => '[0-9]+',
   ),
   array(
      'controller' => 'Album\Controller\Album',
      'action'     => 'index',
   )
));
$router = new Zend\Mvc\Router\Http\TreeRouteStack();
$router->addRoute('default', $route);

// getHref() returns /album/add
$page = new Zend\Navigation\Page\Mvc(array(
    'action'     => 'add',
    'controller' => 'album',
));

// getHref() returns /album/edit/1337
$page = new Zend\Navigation\Page\Mvc(array(
    'action'     => 'edit',
    'controller' => 'album',
    'params'     => array('id' => 1337),
));

isActive() determines if page is active

This example show that MVC pages determine whether they are active by using the params found in the route match object.

/**
 * Dispatched request:
 * - controller: album
 * - action:     index
 */
$page1 = new Zend\Navigation\Page\Mvc(array(
    'action'     => 'index',
    'controller' => 'album',
));

$page2 = new Zend\Navigation\Page\Mvc(array(
    'action'     => 'edit',
    'controller' => 'album',
));

$page1->isActive(); // returns true
$page2->isActive(); // returns false

/**
 * Dispatched request:
 * - controller: album
 * - action:     edit
 * - id:         1337
 */
$page = new Zend\Navigation\Page\Mvc(array(
    'action'     => 'edit',
    'controller' => 'album',
    'params'     => array('id' => 1337),
));

// returns true, because request has the same controller and action
$page->isActive();

/**
 * Dispatched request:
 * - controller: album
 * - action:     edit
 */
$page = new Zend\Navigation\Page\Mvc(array(
    'action'     => 'edit',
    'controller' => 'album',
    'params'     => array('id' => null),
));

// returns false, because page requires the id param to be set in the request
$page->isActive(); // returns false

Using routes

Routes can be used with MVC pages. If a page has a route, this route will be used in getHref() to generate the URL for the page.

Note

Note that when using the route property in a page, you do not need to specify the default params that the route defines (controller, action, etc.).

// the following route is added to the ZF router
$route = Zend\Mvc\Router\Http\Segment::factory(array(
   'route'       => '/a/:id',
   'constraints' => array(
      'id' => '[0-9]+',
   ),
   array(
      'controller' => 'Album\Controller\Album',
      'action'     => 'show',
   )
));
$router = new Zend\Mvc\Router\Http\TreeRouteStack();
$router->addRoute('albumShow', $route);

// a page is created with a 'route' option
$page = new Zend\Navigation\Page\Mvc(array(
    'label'      => 'Show album',
    'route'      => 'albumShow',
    'params'     => array('id' => 42)
));

// returns: /a/42
$page->getHref();
