In the case of the Null adapter, in lieu of a data collection you must supply an item count to its constructor.,Paginating data collections,When all of these values are set, you can render the pagination control inside your view script with a simple echo statement:,In order to paginate items into pages, Zend\Paginator must have a generic way of accessing that data. For that reason, all data access takes place through data source adapters. Several adapters ship with Zend Framework by default:

that you can create a view script to render the paginator controls and the items in the paginator.,As Zak wrote, you are missing , 2 That is because you have to call $paginator->getPages()->pageCount – Goran Jurić Nov 2 '09 at 22:29 ,If I var_dump($paginator), I see the values listed from the query. However, if I echo $paginator->pageCount), I get NULL. What's the deal?

As Zak wrote, you are missing

$paginator - > setItemCountPerPage(10);
$paginator - > setCurrentPageNumber(1);

getItems(int $offset, int $itemCountPerPage) | array,Additionally, you'll typically implement a constructor that takes your data source as a parameter.,Take a look at the packaged adapters for ideas of how you might go about implementing your own.,The caching features depends on the zend-cache component, so be sure to have it installed before getting started:

When retrieving items for the current page, Zend\Paginator\Paginator calls on your adapter's getItems() method, providing it with an offset and the number of items to display per page; your job is to return the appropriate slice of data. For an array, that would be:

return array_slice($this - > array, $offset, $itemCountPerPage);

Creating your own scrolling style requires that you implement Zend\Paginator\ScrollingStyle\ScrollingStyleInterface, which defines a single method:

getPages(Paginator $paginator, int $pageRange = null): array

Unless it extends another scrolling style (see Zend\Paginator\ScrollingStyle\Elastic for an example), your custom scrolling style will inevitably end with something similar to the following line of code:

return $paginator - > getPagesInRange($lowerBound, $upperBound);

When you're ready to use your new scrolling style, you'll need to notif Zend\Paginator\Paginator:

use My\ Paginator\ ScrollingStyle;
use Zend\ Paginator\ Paginator;
use Zend\ ServiceManager\ Factory\ InvokableFactory;

$manager = Paginator::getScrollingStyleManager();
$manager - > setAlias('my-style', ScrollingStyle::class);
$manager - > setFactory(ScrollingStyle::class, InvokableFactory::class);

The caching features depends on the zend-cache component, so be sure to have it installed before getting started:

$ composer require zendframework / zend - cache

Zend\Paginator\Paginator can be told to cache the data it has already used, preventing the adapter from fetching on next request. To tell paginator to automatically cache the adapter's data, pass a pre-configured zend-cache adapter to the static setCache() method:

use Zend\ Cache\ StorageFactory;
use Zend\ Paginator\ Paginator;

$cache = StorageFactory::adapterFactory('filesystem', [
   'cache_dir' => '/tmp',
   'ttl' => 3600,
   'plugins' => ['serializer'],
]);
Paginator::setCache($cache);

As long as the Paginator class has been seeded with a cache storage object, the data any instance generates will be cached. If you want to disable caching, call setCacheEnabled() with a boolean false on a concrete instance:

use Zend\ Paginator\ Paginator;

// $cache is a Zend\Cache\Storage\StorageInterface instance
Paginator::setCache($cache);

// ... later on the script:
$paginator - > setCacheEnabled(false);
// cache is now disabled for this instance.

When a cache is set, data are automatically stored in it and pulled out from it. It then can be useful to empty the cache manually. You can get this done by calling clearPageItemCache($pageNumber). If you don't pass any parameter, the whole cache will be empty. You can optionally pass a parameter representing the page number to empty in the cache:

use Zend\ Paginator\ Paginator;

// $cache is a Zend\Cache\Storage\StorageInterface instance
Paginator::setCache($cache);

// $paginator is a fully configured Paginator instance:
$items = $paginator - > getCurrentItems();

$page3Items = $paginator - > getItemsByPage(3);
// page 3 is now in cache

// clear the cache of the results for page 3
$paginator - > clearPageItemCache(3);

// clear all the cache data
$paginator - > clearPageItemCache();

Changing the item count per page will empty the whole cache as it would have become invalid:

use Zend\ Paginator\ Paginator;

// $cache is a Zend\Cache\Storage\StorageInterface instance
Paginator::setCache($cache);

// Fetch some items from an instance:
$items = $paginator - > getCurrentItems();

// Changing item count flushes the cache:
$paginator - > setItemCountPerPage(2);

It is also possible to see the data in cache and ask for it directly. getPageItemCache() can be used for that:

use Zend\ Paginator\ Paginator;

// $cache is a Zend\Cache\Storage\StorageInterface instance
Paginator::setCache($cache);

// Set the item count:
$paginator - > setItemCountPerPage(3);

// Fetch some items:
$items = $paginator - > getCurrentItems();
$otherItems = $paginator - > getItemsPerPage(4);

// See the cached items as a two-dimensional array:
var_dump($paginator - > getPageItemCache());

First of all, we'll have to slightly modify the way we get the list of posts. Previously, we used the findBy() method of the EntityRepository, which returns array of posts. But now we'll have to do that with our custom repository class PostRepository, because Doctrine ORM paginator takes Query object on input, not an array of posts.,In lines 22 and 27, we retrieve the Query object from our PostRepository instead of array of posts. We then pass this Query object to the ZF3 paginator in line 31., You will also need to slightly modify the PostManager::getTagCloud() method, because it expects an array of posts, but now it will receive the Query. It is a simple and obvious modification, so we won't describe how to do that (refer to Blog sample for the complete code). ,the $posts is the Paginator object that we passed from controller's action with the ViewModel variable container.

In Zend Framework 3, pagination is implemented in Zend\Paginator component. If you haven't installed this component, do so by typing the following command:

php composer.phar require zendframework / zend - paginator

For example, i have a array data like this :,Zend Framework/Laminas Training,Zend Framework has a component named Zend\Paginator. It can paginate items into pages, paginate arbitrary data, not just relational databases, and fetch only the results that need to be displayed.,Saya lagi mempelajari Zend\Paginator\Paginator


For example, i have a array data like this :

$dataItems = array(
   0 => array('id' => 1, 'name' => 'samsonasik'),
   1 => array('id' => 2, 'name' => 'abdul malik ikhsan'),
   2 => array('id' => 3, 'name' => 'superman'),
);

And route :

'Test' => array(
   'type' => 'Segment',
   'options' => array(
      // Change this to something specific to your module
      'route' => '/[:lang]/test[/:page]',
      'defaults' => array(
         '__NAMESPACE__' => 'Test\Controller',
         'controller' => 'Test',
         'action' => 'index',
      ),
   ),
   //........
),

and we will access as http://localhost/zf2app/public/en/test/1 or http://localhost/zf2app/public/en/test/2.
First step, we create a Requesthelper view helper for handling GET parameter if passed by url.

namespace Test\ View\ Helper;
use Zend\ View\ Helper\ AbstractHelper;

class Requesthelper extends AbstractHelper {
   protected $request;

   //get Request
   public
   function setRequest($request) {
      $this - > request = $request;
   }

   public
   function getRequest() {
      return $this - > request;
   }

   public
   function __invoke() {
      return $this - > getRequest() - > getServer() - > get('QUERY_STRING');
   }
}

And then, register it and pass Request object :

'Requesthelper' => function($sm) {
   $helper = new View\ Helper\ Requesthelper;
   $request = $sm - > getServiceLocator() - > get('Request');
   $helper - > setRequest($request);
   return $helper;
}

Next, create a file, for example named pager.phtml:
and write the following of codes into pager.pthml :

<?php
$url = $this->url('Test', array('lang'=>$this->lang));
//handle parameter get 🙂
$parameterGet = $this->Requesthelper();
if ($parameterGet != ""){
  $parameterGet = "?".$parameterGet;
}
?>

<?php if ($this->pageCount): ?>
<div class="paginationControl">
    <p>
	    <!--<div style="float:left">-->
      <!-- Previous page link -->
      <?php if (isset($this->previous)): ?>
     <a class="first" href="<?= $url.'/1'; ?>">&lt;&lt; first&nbsp;&nbsp;</a>
     <a class="Previous" href="<?= $url.'/'.$this->previous.$parameterGet; ?>">&lt; prev&nbsp;&nbsp;</a>      
      <?php else: ?>
      <b><i>&lt;&lt; first&nbsp;&nbsp;</i></b>
      <b><i>&lt; prev&nbsp;&nbsp;</i></b>      
      <?php endif; ?>
      <?php foreach ($this->pagesInRange as $page): ?>
      <?php if ($page != $this->current): ?>
        <a class="nopage" href="<?= $url.'/'.$page.$parameterGet; ?>">
      <?= $page; ?>
      </a>&nbsp;
      <?php else: ?>
            <span class="nopage">
      <?= $page; ?>
    </span>
      </b>&nbsp;
      <?php endif; ?>
      <?php endforeach; ?>
      <?php if (isset($this->next)): ?>
      <a class="next" href="<?= $url.'/'.$this->next.$parameterGet; ?>">&nbsp;next &gt;</a>
      <a class="next" href="<?= $url.'/'.$this->pageCount.$parameterGet; ?>">&nbsp;last &gt;&gt;</a>
      <?php else: ?>      	
	   <b><i>&nbsp;next &gt;&nbsp;</i></b>
	   <b><i>&nbsp;last &gt;&gt;&nbsp;</i></b>
      <?php endif; ?>
    </p>
</div>
<?php endif; ?>

Preparation done, so we can set the fake data to test it in the controller and pass the data to the component :

$matches = $this - > getEvent() - > getRouteMatch();
$page = $matches - > getParam('page', 1);

$dataItems = array(
   0 => array('id' => 1, 'name' => 'samsonasik'),
   1 => array('id' => 2, 'name' => 'abdul malik ikhsan'),
   2 => array('id' => 3, 'name' => 'superman'),
);
$paginator = new\ Zend\ Paginator\ Paginator(new\ Zend\ Paginator\ Adapter\ ArrayAdapter($dataItems));

$paginator - > setCurrentPageNumber($page);
$paginator - > setItemCountPerPage(2);

return new ViewModel(array(
   'test' => $paginator,
   'lang' => $matches - > getParam('lang', 'en')
));

So, in View, we can call :

<?php foreach($test as $key=>$row) : ?>
<?php echo $row['id']; ?> : <?php echo $row['name']; ?> <br />
<?php endforeach; ?>

<?= ( count($test) > 0 ) ? $this->paginationControl($test, 'Sliding', 'pager.phtml', array('lang'=>$lang)) : ""; ?>


[UPDATE]
How about Paginate data from database ?
First, buffer() the resultSet object :

..................
public
function fetchAll() {
   $resultSet = $this - > select(function(Select $select) {
      $select - > columns(array('id', 'name'));
      $select - > order(array('id asc'));
   });

   $resultSet - > buffer();
   $resultSet - > next();

   return $resultSet;
}
...................

And use Iterator adapter :

        $iteratorAdapter = new\ Zend\ Paginator\ Adapter\ Iterator($this - > getSampleTable() - > fetchAll());
        $paginator = new\ Zend\ Paginator\ Paginator($iteratorAdapter);
