Containers have methods for adding, retrieving, deleting and
iterating pages. Containers implement the
SPL interfaces
RecursiveIterator and
Countable, meaning that a container can
be iterated using the SPL
RecursiveIteratorIterator class.
Zend_Navigation_Container is
abstract, and can not be instantiated directly. Use
Zend_Navigation if you want to
instantiate a container.
Zend_Navigation can be constructed
entirely empty, or take an array or a
Zend_Config object with pages to put in the
container. Each page in the given array/config will eventually be
passed to the addPage() method of the container class,
which means that each element in the array/config can be an array or
a config object, or a Zend_Navigation_Page
instance.

$config = new Zend_Config_Yaml'/path/to/navigation.yaml', 'nav'); $container = new Zend_Navigation($config);
Adding pages to a container can be done with the methods
addPage(), addPages(), or
setPages(). See examples below for explanation.
Exemplo 616. Adding pages to a container
// create container
$container = new Zend_Navigation();
// add page by giving a page instance
$container->addPage(Zend_Navigation_Page::factory(array(
'uri' => 'http://www.example.com/',
)));
// add page by giving an array
$container->addPage(array(
'uri' => 'http://www.example.com/',
));
// add page by giving a config object
$container->addPage(new Zend_Config(array(
'uri' => 'http://www.example.com/',
)));
$pages = array(
array(
'label' => 'Save',
'action' => 'save',
),
array(
'label' => 'Delete',
'action' => 'delete',
),
);
// add two pages
$container->addPages($pages);
// add container
$container->addPages(new Zend_Navigation(array(
array(
'label' => 'Move up',
'action' => 'up',
),
array(
'label' => 'Move down',
'action' => 'down',
),
)));
// remove existing pages and add the given pages
$container->setPages($pages);
Removing pages can be done with removePage() or
removePages(). The first method accepts a an instance
of a page, or an integer. The integer corresponds to the
order a page has. The latter method will remove all
pages in the container.
Exemplo 617. Removing pages from a container
$container = new Zend_Navigation(array(
array(
'label' => 'Page 1',
'action' => 'page1'
),
array(
'label' => 'Page 2',
'action' => 'page2',
'order' => 200
),
array(
'label' => 'Page 3',
'action' => 'page3'
)
));
// remove page by implicit page order
$container->removePage(0); // removes Page 1
// remove page by instance
$page3 = $container->findOneByAction('page3');
$container->removePage($page3); // removes Page 3
// remove page by explicit page order
$container->removePage(200); // removes Page 2
// remove all pages
$container->removePages(); // removes all pages
Containers have finder methods for retrieving pages.
They are findOneBy($property, $value, $useRegex = false),
findAllBy($property, $value, $useRegex = false), and
findBy($property, $value, $all = false, $useRegex = false).
Those methods will recursively search the container for
pages matching the given $page->$property == $value
or when regular expressions are used:
preg_match($value, $page->$property).
The first method, findOneBy(), will return a
single page matching the property with the given value, or
NULL if it cannot be found. The second method will return
all pages with a property matching the given value. The third
method will call one of the two former methods depending on the
$all flag.
The finder methods can also be used magically by appending the
property name to findBy, findOneBy, or
findAllBy, e.g. findOneByLabel('Home') to
return the first matching page with label 'Home'.
Other combinations are findByLabel(...),
findOnyByTitle(...),
findAllByController(...), etc. Finder
methods also work on custom properties, such as
findByFoo('bar').
Exemplo 618. Finding pages in a container
$container = new Zend_Navigation(array(
array(
'label' => 'Page 1',
'uri' => 'page-1',
'foo' => 'bar',
'pages' => array(
array(
'label' => 'Page 1.1',
'uri' => 'page-1.1',
'foo' => 'bar',
),
array(
'label' => 'Page 1.2',
'uri' => 'page-1.2',
'class' => 'my-class',
),
array(
'type' => 'uri',
'label' => 'Page 1.3',
'uri' => 'page-1.3',
'action' => 'about'
)
)
),
array(
'label' => 'Page 2',
'id' => 'page_2_and_3',
'class' => 'my-class',
'module' => 'page2',
'controller' => 'index',
'action' => 'page1'
),
array(
'label' => 'Page 3',
'id' => 'page_2_and_3',
'module' => 'page3',
'controller' => 'index'
)
));
// The 'id' is not required to be unique, but be aware that
// having two pages with the same id will render the same id attribute
// in menus and breadcrumbs.
$found = $container->findBy('id', 'page_2_and_3'); // returns Page 2
$found = $container->findOneBy('id', 'page_2_and_3'); // returns Page 2
$found = $container->findBy('id', 'page_2_and_3', true); // returns Page 2 and Page 3
$found = $container->findById('page_2_and_3'); // returns Page 2
$found = $container->findOneById('page_2_and_3'); // returns Page 2
$found = $container->findAllById('page_2_and_3'); // returns Page 2 and Page 3
// Find all matching CSS class my-class
$found = $container->findAllBy('class', 'my-class'); // returns Page 1.2 and Page 2
$found = $container->findAllByClass('my-class'); // returns Page 1.2 and Page 2
// Find first matching CSS class my-class
$found = $container->findOneByClass('my-class'); // returns Page 1.2
// Find all matching CSS class non-existant
$found = $container->findAllByClass('non-existant'); // returns array()
// Find first matching CSS class non-existant
$found = $container->findOneByClass('non-existant'); // returns null
// Find all pages with custom property 'foo' = 'bar'
$found = $container->findAllBy('foo', 'bar'); // returns Page 1 and Page 1.1
// To achieve the same magically, 'foo' must be in lowercase.
// This is because 'foo' is a custom property, and thus the
// property name is not normalized to 'Foo'
$found = $container->findAllByfoo('bar');
// Find all with controller = 'index'
$found = $container->findAllByController('index'); // returns Page 2 and Page 3
Use regular expressions to find pages:
$found = $container->findBy('class','/my/', false, true); // returns Page 1.2
$found = $container->findOneBy('class', '/my/', true); // returns Page 1.2
$found = $container->findBy('class', '/my/', true, true); // returns Page 1.2 and Page 2
$found = $container->findAllBy('class', '/my/', true); // returns Page 1.2 and Page 2
$found = $container->findOneByClass('/my/', true); // returns Page 1.2
$found = $container->findAllByClass('/my/', true); // returns Page 1.2 and Page 2
Zend_Navigation_Container implements
RecursiveIteratorIterator, and can be
iterated using any Iterator class. To iterate
a container recursively, use the
RecursiveIteratorIterator class.
Exemplo 619. Iterating a container
/*
* Create a container from an array
*/
$container = new Zend_Navigation(array(
array(
'label' => 'Page 1',
'uri' => '#'
),
array(
'label' => 'Page 2',
'uri' => '#',
'pages' => array(
array(
'label' => 'Page 2.1',
'uri' => '#'
),
array(
'label' => 'Page 2.2',
'uri' => '#'
)
)
),
array(
'label' => 'Page 3',
'uri' => '#'
)
));
// Iterate flat using regular foreach:
// Output: Page 1, Page 2, Page 3
foreach ($container as $page) {
echo $page->label;
}
// Iterate recursively using RecursiveIteratorIterator
$it = new RecursiveIteratorIterator(
$container, RecursiveIteratorIterator::SELF_FIRST);
// Output: Page 1, Page 2, Page 2.1, Page 2.2, Page 3
foreach ($it as $page) {
echo $page->label;
}
The method hasPage(Zend_Navigation_Page $page) checks
if the container has the given page. The method hasPages()
checks if there are any pages in the container, and is equivalent
to count($container) > 1.
The toArray() method converts the container and the
pages in it to an array. This can be useful for serializing and
debugging.
Exemplo 620. Converting a container to an array
$container = new Zend_Navigation(array(
array(
'label' => 'Page 1',
'uri' => '#'
),
array(
'label' => 'Page 2',
'uri' => '#',
'pages' => array(
array(
'label' => 'Page 2.1',
'uri' => '#'
),
array(
'label' => 'Page 2.2',
'uri' => '#'
)
)
)
));
var_dump($container->toArray());
