Pagerfanta

Pagination for PHP 5.3

Usage

use Pagerfanta\Pagerfanta;
use Pagerfanta\Adapter\ArrayAdapter;

$adapter = new ArrayAdapter($array);
$pagerfanta = new Pagerfanta($adapter);

$pagerfanta->setMaxPerPage($maxPerPage); // 10 by default
$maxPerPage = $pagerfanta->getMaxPerPage();

$pagerfanta->setCurrentPage($currentPage); // 1 by default
$currentPage = $pagerfanta->getCurrentPage();

$nbResults = $pagerfanta->getNbResults();
$currentPageResults = $pagerfanta->getCurrentPageResults();

$pagerfanta->getNbPages();

$pagerfanta->haveToPaginate(); // whether the number of results if higher than the max per page

$pagerfanta->hasPreviousPage();
$pagerfanta->getPreviousPage();
$pagerfanta->hasNextPage();
$pagerfanta->getNextPage();

The ->setMaxPerPage() and ->setCurrentPage() methods implement a fluent interface:

$pagerfanta
    ->setMaxPerPage($maxPerPage)
    ->setCurrentPage($currentPage)
;

The ->setMaxPerPage() method throws an exception if the max per page is not valid:

• Pagerfanta\Exception\NotIntegerMaxPerPageException (or integer in string)
• Pagerfanta\Exception\LessThan1MaxPerPageException

Both extends from Pagerfanta\Exception\NotValidMaxPerPageException.

The ->setCurrentPage() method throws an exception if the page is not valid:

• Pagerfanta\Exception\NotIntegerCurrentPageException (or integer in string)
• Pagerfanta\Exception\LessThan1CurrentPageException
• Pagerfanta\Exception\OutOfRangeCurrentPageException

All of them extends from Pagerfanta\Exception\NotValidCurrentPageException.

Adapters

The adapter's concept is very simple. An adapter just returns the number of results and an slice for a offset and length. This way you can adapt a pagerfanta to paginate any kind results simply creating an adapter.

An adapter must implement the Pagerfanta\Adapter\AdapterInterface interface, which has these two methods:

/**
 * Returns the number of results.
 *
 * @return integer The number of results.
 *
 * @api
 */
function getNbResults();

/**
 * Returns an slice of the results.
 *
 * @param integer $offset The offset.
 * @param integer $length The length.
 *
 * @return array The slice.
 *
 * @api
 */
function getSlice($offset, $length);

Pagerfanta comes with six adapters:

ArrayAdapter

To paginate an array.

use Pagerfanta\Adapter\ArrayAdapter;

$adapter = new ArrayAdapter($array);

### MandangoAdapter

To paginate Mandango Queries.

use Pagerfanta\Adapter\MandangoAdapter;

$query = \Model\Article::getRepository()->createQuery();
$adapter = new MandangoAdapter($query);

### DoctrineORMAdapter

To paginate DoctrineORM query objects.

use Pagerfanta\Adapter\DoctrineORMAdapter;

$queryBuilder = $entityManager->createQueryBuilder()
    ->select('u')
    ->from('Model\Article', 'u')
;
$adapter = new DoctrineORMAdapter($query);

To paginate fetch joined collections correctly you can set the second variable $fetchJoinCollection to the constructor to true:

use Pagerfanta\Adapter\DoctrineORMAdapter;

$dql = "SELECT u, g FROM Pagerfanta\Tests\Adapter\DoctrineORM\User u INNER JOIN u.groups g";
$query = $entityManager->createQuery($dql);

$adapter = new DoctrineORMAdapter($queryBuilder->getQuery(), true);

This will use a limit subquery + where-in strategy (using 2 queries instead of 1) to determine the slice which should be returned.

DoctrineODMMongoDBAdapter

To paginate DoctrineODMMongoDB query builders.

use Pagerfanta\Adapter\DoctrineODMMongoDBAdapter;

$queryBuilder = $documentManager->createQueryBuilder('Model\Article');
$adapter = new DoctrineODMMongoDBAdapter($queryBuilder);

DoctrineCollectionAdapter

To paginate a Doctrine\Common\Collection\Collections interface you can use the DoctrineCollectionAdapter. It proxies to the count() and slice() methods on the Collections interface for pagination. This makes sense if you are using Doctrine ORMs Extra Lazy association features:

use Pagerfanta\Adapter\DoctrineCollectionAdapter;

$user = $em->find("Pagerfanta\Tests\Adapter\DoctrineORM\User", 1);

$adapter = new DoctrineCollectionAdapter($user->getGroups());

PropelAdapter

To paginate a propel query:

use Pagerfanta\Adapter\PropelAdapter;

$adapter = new PropelAdapter($query);

Views

The views are to render pagerfantas, this way you can reuse your pagerfantas' html in several projects, share them and use another ones from another developers.

The views implement the Pagerfanta\View\ViewInterface interface, which has two methods:

/**
 * Renders a pagerfanta.
 *
 * The route generator is any callable to generate the routes receiving the page number
 * as first and unique argument.
 *
 * @param PagerfantaInterface $pagerfanta      A pagerfanta.
 * @param mixed               $routeGenerator A callable to generate the routes.
 * @param array               $options        An array of options (optional).
 *
 * @api
 */
function render(PagerfantaInterface $pagerfanta, $routeGenerator, array $options = array());

/**
 * Returns the canonical name.
 *
 * @return string The canonical name.
 *
 * @api
 */
function getName();

RouteGenerator example:

$routeGenerator = function($page) {
    return '/path?page='.$page;
}

Pagerfanta comes with three views, the default one, one for and an special optionable view.

### DefaultView

This is the default view.

use Pagerfanta\View\DefaultView;

$view = new DefaultView();
$html = $view->render($pagerfanta, $routeGenerator, array(
    'proximity' => 3,
));

Options (default):

• proximity (3)
• previous_message (Previous)
• next_message (Next)
• css_disabled_class (disabled)
• css_dots_class (dots)
• css_current_class (current)

CSS:

.pagerfanta {
}

.pagerfanta a,
.pagerfanta span {
    display: inline-block;
    border: 1px solid blue;
    color: blue;
    margin-right: .2em;
    padding: .25em .35em;
}

.pagerfanta a {
    text-decoration: none;
}

.pagerfanta a:hover {
    background: #ccf;
}

.pagerfanta .dots {
    border-width: 0;
}

.pagerfanta .current {
    background: #ccf;
    font-weight: bold;
}

.pagerfanta .disabled {
    border-color: #ccf;
    color: #ccf;
}

COLORS:

.pagerfanta a,
.pagerfanta span {
    border-color: blue;
    color: blue;
}

.pagerfanta a:hover {
    background: #ccf;
}

.pagerfanta .current {
    background: #ccf;
}

.pagerfanta .disabled {
    border-color: #ccf;
    color: #cf;
}

TwitterBootstrapView

This view generates a pagination for .

use Pagerfanta\View\TwitterBootstrapView;

$view = new TwitterBootstrapView();
$html = $view->render($pagerfanta, $routeGenerator, array(
    'proximity' => 3,
));

Options (default):

• proximity (3)
• prev_message (← Previous)
• prev_disabled_href ()
• next_message (Next)
• next_disabled_href ()
• dots_message (…)
• dots_href ()
• css_disabled_class (pagination)
• css_previous_class (prev)
• css_next_class (next)
• css_disabled_class (disabled)
• css_dots_class (disabled)
• css_active_class (active)

### OptionableView

This view is to reuse options in different views.

use Pagerfanta\DefaultView;
use Pagerfanta\OptionableView;

$defaultView = new DefaultView();

// view and default options
$myView1 = new OptionableView($defaultView, array('proximity' => 3));

$myView2 = new OptionableView($defaultView, array('previous_message' => 'Anterior', 'next_message' => 'Siguiente'));

// using in a normal way
$pagerfantaHtml = $myView2->render($pagerfanta, $routeGenerator);

// overwriting default options
$pagerfantaHtml = $myView2->render($pagerfanta, $routeGenerator, array('next_message' => 'Siguiente!!'));
