Using zend-paginator in your Album Module

In this tutorial, we will use the zend-paginator component to add a handy pagination controller to the bottom of the album list.

Currently, we only have a handful of albums to display, so showing everything on one page is not a problem. However, how will the album list look when we have 100 albums or more in our database? The standard solution to this problem is to split the data up into a number of pages, and allow the user to navigate around these pages using a pagination control. Just type "Zend Framework" into Google, and you can see their pagination control at the bottom of the page:

Example pagination control


As before, we are going to use sqlite, via PHP's PDO driver. Create a text file data/album-fixtures.sql with the following contents:

(The test data chosen happens to be the current 150 top iTunes albums at the time of writing!)

Now create the database using the following:

$ sqlite data/zftutorial.db < data/album-fixtures.sql

Some systems, including Ubuntu, use the command sqlite3; check to see which one to use on your system.

Using PHP to create the database

If you do not have Sqlite installed on your system, you can use PHP to load the database using the same SQL schema file created earlier. Create the file data/load_album_fixtures.php with the following contents:

$db = new PDO('sqlite:' . realpath(__DIR__) . '/zftutorial.db');
$fh = fopen(__DIR__ . '/album-fixtures.sql', 'r');
while ($line = fread($fh, 4096)) {

Once created, execute it:

$ php data/load_album_fixtures.php

This gives us a handy extra 150 rows to play with. If you now visit your album list at /album, you'll see a huge long list of 150+ albums; it's ugly.

Install zend-paginator

zend-paginator is not installed or configured by default, so we will need to do that. Run the following from the application root:

$ composer require zendframework/zend-paginator

Assuming you followed the Getting Started tutorial, you will be prompted by the zend-component-installer plugin to inject Zend\Paginator; be sure to select the option for either config/application.config.php or config/modules.config.php; since it is the only package you are installing, you can answer either "y" or "n" to the "Remember this option for other packages of the same type" prompt.

Manual configuration

If you are not using zend-component-installer, you will need to setup configuration manually. You can do this in one of two ways:

  • Register the Zend\Paginator module in either config/application.config.php or config/modules.config.php. Make sure you put it towards the top of the module list, before any modules you have defined or third party modules you are using.
  • Alternately, add a new file, config/autoload/, with the following contents:
use Zend\Paginator\ConfigProvider;

return [
    'service_manager' => (new ConfigProvider())->getDependencyConfig(),

Once installed, our application is now aware of zend-paginator, and even has some default factories in place, which we will now make use of.

Modifying the AlbumTable

In order to let zend-paginator handle our database queries automatically for us, we will be using the DbSelect pagination adapter This will automatically manipulate and run a Zend\Db\Sql\Select object to include the correct LIMIT and WHERE clauses so that it returns only the configured amount of data for the given page. Let's modify the fetchAll method of the AlbumTable model, so that it can optionally return a paginator object:

// in module/Album/src/Model/AlbumTable.php:
namespace Album\Model;

use RuntimeException;
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\Sql\Select;
use Zend\Db\TableGateway\TableGatewayInterface;
use Zend\Paginator\Adapter\DbSelect;
use Zend\Paginator\Paginator;

class AlbumTable
    /* ... */

    public function fetchAll($paginated = false)
        if ($paginated) {
            return $this->fetchPaginatedResults();

        return $this->tableGateway->select();

    private function fetchPaginatedResults()
        // Create a new Select object for the table:
        $select = new Select($this->tableGateway->getTable());

        // Create a new result set based on the Album entity:
        $resultSetPrototype = new ResultSet();
        $resultSetPrototype->setArrayObjectPrototype(new Album());

        // Create a new pagination adapter object:
        $paginatorAdapter = new DbSelect(
            // our configured select object:
            // the adapter to run it against:
            // the result set to hydrate:

        $paginator = new Paginator($paginatorAdapter);
        return $paginator;

    /* ... */

This will return a fully configured Paginator instance. We've already told the DbSelect adapter to use our created Select object, to use the adapter that the TableGateway object uses, and also how to hydrate the result into a Album entity in the same fashion as the TableGateway does. This means that our executed and returned paginator results will return Album objects in exactly the same fashion as the non-paginated results.

Modifying the AlbumController

Next, we need to tell the album controller to provide the view with a Pagination object instead of a ResultSet. Both these objects can by iterated over to return hydrated Album objects, so we won't need to make many changes to the view script:

// in module/Album/src/Controller/AlbumController.php:

/* ... */

public function indexAction()
    // Grab the paginator from the AlbumTable:
    $paginator = $this->table->fetchAll(true);

    // Set the current page to what has been passed in query string,
    // or to 1 if none is set, or the page is invalid:
    $page = (int) $this->params()->fromQuery('page', 1);
    $page = ($page < 1) ? 1 : $page;

    // Set the number of items per page to 10:

    return new ViewModel(['paginator' => $paginator]);

/* ... */

Here we are getting the configured Paginator object from the AlbumTable, and then telling it to use the page that is optionally passed in the querystring page parameter (after first validating it). We are also telling the paginator we want to display 10 albums per page.

Updating the View Script

Now, tell the view script to iterate over the pagination view variable, rather than the albums variable:

<?php // in module/Album/view/album/album/index.phtml:
$title = 'My albums';
<h1><?= $this->escapeHtml($title); ?></h1>
    <a href="<?= $this->url('album', ['action' => 'add']) ?>">Add new album</a>

<table class="table">
    <?php foreach ($this->paginator as $album) : // <-- change here! ?>
            <td><?= $this->escapeHtml($album->title) ?></td>
            <td><?= $this->escapeHtml($album->artist) ?></td>
                <a href="<?= $this->url('album', ['action' => 'edit', 'id' => $album->id]) ?>">Edit</a>
                <a href="<?= $this->url('album', ['action' => 'delete', 'id' => $album->id]) ?>">Delete</a>
    <?php endforeach; ?>

Checking the /album route on your website should now give you a list of just 10 albums, but with no method to navigate through the pages. Let's correct that now.

Creating the Pagination Control Partial

Much like we created a custom breadcrumbs partial to render our breadcrumb in the navigation tutorial, we need to create a custom pagination control partial to render our pagination control just the way we want it. Again, because we are using Bootstrap, this will primarily involve outputting correctly formatted HTML. Let's create the partial in the module/Application/view/partial/ folder, so that we can use the control in all our modules:

<?php // in module/Application/view/partial/paginator.phtml: ?>
<?php if ($this->pageCount): ?>
  <ul class="pagination">
  <!-- Previous page link -->
  <?php if (isset($this->previous)): ?>
      <a href="<?= $this->url($this->route, [], ['query' => ['page' => $this->previous]]) ?>">
  <?php else: ?>
    <li class="disabled">
      <a href="#">
  <?php endif ?>

  <!-- Numbered page links -->
  <?php foreach ($this->pagesInRange as $page): ?>
    <?php if ($page !== $this->current): ?>
        <a href="<?= $this->url($this->route, [], ['query' => ['page' => $page]]) ?>">
          <?= $page ?>
    <?php else: ?>
      <li class="active">
        <a href="#"><?= $page ?></a>
    <?php endif ?>
  <?php endforeach ?>

  <!-- Next page link -->
  <?php if (isset($this->next)): ?>
      <a href="<?= $this->url($this->route, [], ['query' => ['page' => $this->next]]) ?>">
  <?php else: ?>
    <li class="disabled">
      <a href="#">
  <?php endif ?>
<?php endif ?>

This partial creates a pagination control with links to the correct pages (if there is more than one page in the pagination object). It will render a previous page link (and mark it disabled if you are at the first page), then render a list of intermediate pages (that are passed to the partial based on the rendering style; we'll pass that to the view helper in the next step). Finally, it will create a next page link (and disable it if you're at the end). Notice how we pass the page number via the page querystring parameter which we have already told our controller to use to display the current page.

Using the PaginationControl View Helper

To page through the albums, we need to invoke the paginationControl view helper to display our pagination control:

// In module/Album/view/album/album/index.phtml:
// Add at the end of the file after the table:
<?= $this->paginationControl(
    // The paginator object:
    // The scrolling style:
    // The partial to use to render the control:
    // The route to link to when a user clicks a control link:
    ['route' => 'album']
) ?>

The above echoes the paginationControl helper, and tells it to use our paginator instance, the sliding scrolling style, our paginator partial, and which route to use for generating links. Refreshing your application now should give you Bootstrap-styled pagination controls!
