Pagination for PHP 5.3
<?php
use Pagerfanta\Adapter\ArrayAdapter;
use Pagerfanta\Pagerfanta;
$adapter = new ArrayAdapter($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:
<?php
$pagerfanta
->setMaxPerPage($maxPerPage)
->setCurrentPage($currentPage);
The ->setMaxPerPage()
method throws an exception if the max per page
is not valid:
Pagerfanta\Exception\NotIntegerMaxPerPageException
Pagerfanta\Exception\LessThan1MaxPerPageException
Both extend from Pagerfanta\Exception\NotValidMaxPerPageException
.
The ->setCurrentPage()
method throws an exception if the page is not valid:
Pagerfanta\Exception\NotIntegerCurrentPageException
Pagerfanta\Exception\LessThan1CurrentPageException
Pagerfanta\Exception\OutOfRangeCurrentPageException
All of them extend from Pagerfanta\Exception\NotValidCurrentPageException
.
->setCurrentPage()
throws an out ot range exception depending on the
max per page, so if you are going to modify the max per page, you should do it
before setting the current page.
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 by creating an adapter.
An adapter must implement the Pagerfanta\Adapter\AdapterInterface
interface, which has these two methods:
<?php
/**
* Returns the number of results.
*
* @return integer The number of results.
*/
function getNbResults();
/**
* Returns an slice of the results.
*
* @param integer $offset The offset.
* @param integer $length The length.
*
* @return array|\Iterator|\IteratorAggregate The slice.
*/
function getSlice($offset, $length);
Pagerfanta comes with these adapters:
To paginate an array.
<?php
use Pagerfanta\Adapter\ArrayAdapter;
$adapter = new ArrayAdapter($array);
To paginate Mongo Cursors.
<?php
use Pagerfanta\Adapter\MongoAdapter;
$cursor = $collection->find();
$adapter = new MongoAdapter($cursor);
To paginate Mandango Queries.
<?php
use Pagerfanta\Adapter\MandangoAdapter;
$query = $mandango->getRepository('Model\Article')->createQuery();
$adapter = new MandangoAdapter($query);
To paginate DoctrineDbal query builders.
<?php
use Pagerfanta\Adapter\DoctrineDbalAdapter;
use Doctrine\DBAL\Query\QueryBuilder;
$queryBuilder = new QueryBuilder($conn);
$queryBuilder->select('p.*')->from('posts', 'p');
$countQueryBuilderModifier = function ($queryBuilder) {
$queryBuilder->select('COUNT(DISTINCT p.id) AS total_results')
->setMaxResults(1);
};
$adapter = new DoctrineDbalAdapter($queryBuilder, $countQueryBuilderModifier);
To simplify the pagination of single table DoctrineDbal query builders.
This adapter only paginates single table query builders, without joins.
<?php
use Pagerfanta\Adapter\DoctrineDbalSingleTableAdapter;
use Doctrine\DBAL\Query\QueryBuilder;
$queryBuilder = new QueryBuilder($conn);
$queryBuilder->select('p.*')->from('posts', 'p');
$countField = 'p.id';
$adapter = new DoctrineDbalSingleTableAdapter($queryBuilder, $countField);
To paginate DoctrineORM query objects.
<?php
use Pagerfanta\Adapter\DoctrineORMAdapter;
$queryBuilder = $entityManager->createQueryBuilder()
->select('u')
->from('Model\Article', 'u');
$adapter = new DoctrineORMAdapter($queryBuilder);
To paginate DoctrineODMMongoDB query builders.
<?php
use Pagerfanta\Adapter\DoctrineODMMongoDBAdapter;
$queryBuilder = $documentManager->createQueryBuilder('Model\Article');
$adapter = new DoctrineODMMongoDBAdapter($queryBuilder);
To paginate Doctrine PHPCR-ODM query builders.
<?php
use Pagerfanta\Adapter\DoctrineODMPhpcrAdapter;
$queryBuilder = $documentManager->createQueryBuilder();
$queryBuilder->from('Model\Article');
$adapter = new DoctrineODMPhpcrAdapter($queryBuilder);
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:
<?php
use Pagerfanta\Adapter\DoctrineCollectionAdapter;
$user = $em->find("Pagerfanta\Tests\Adapter\DoctrineORM\User", 1);
$adapter = new DoctrineCollectionAdapter($user->getGroups());
To paginate a Doctrine\Common\Collection\Selectable
interface
you can use the DoctrineSelectableAdapter
. It uses the matching()
method on the Selectable interface for pagination. This is
especially usefull when using the Doctrine Criteria object to
filter a PersistentCollection:
<?php
use Pagerfanta\Adapter\DoctrineSelectableAdapter;
use Doctrine\Common\Collections\Criteria;
$user = $em->find("Pagerfanta\Tests\Adapter\DoctrineORM\User", 1);
$comments = $user->getComments();
$criteria = Criteria::create()->andWhere(Criteria::expr()->in('id', array(1,2,3));
$adapter = new DoctrineSelectableAdapter($comments, $criteria);
Note that you should never use this adapter with a PersistentCollection which is not set to use the EXTRA_LAZY fetch mode.
Be carefull when using the count()
method, currently Doctrine2
needs to fetch all the records to count the number of elements.
To paginate an Elastica Query query:
<?php
use Elastica\Index;
use Elastica\Query;
use Elastica\Query\Term;
use Pagerfanta\Adapter\ElasticaAdapter;
// Searchable can be any valid searchable Elastica object. For example a Type or Index
$searchable = new Index($elasticaClient, 'index_name');
// A Query can be any valid Elastica query (json, array, Query object)
$query = new Query::create(new Term(array(
'name' => 'Fred'
));
$adapter = new ElasticaAdapter($searchable, $query);
To paginate a propel query:
<?php
use Pagerfanta\Adapter\PropelAdapter;
$adapter = new PropelAdapter($query);
To paginate a solarium query:
<?php
use Pagerfanta\Adapter\SolariumAdapter;
$query = $solarium->createSelect();
$query->setQuery('search term');
$adapter = new SolariumAdapter($solarium, $query);
Best used when you need to do a custom paging solution and don't want to implement a full adapter for a one-off use case.
It returns always the same data no matter what page you query:
<?php
use Pagerfanta\Adapter\FixedAdapter;
$nbResults = 5;
$results = array(/* ... */);
$adapter = new FixedAdapter($nbResults, $results);
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:
<?php
/**
* 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).
*/
function render(PagerfantaInterface $pagerfanta, $routeGenerator, array $options = array());
/**
* Returns the canonical name.
*
* @return string The canonical name.
*/
function getName();
RouteGenerator example:
<?php
$routeGenerator = function($page) {
return '/path?page='.$page;
}
Pagerfanta comes with three views, the default one, one for Twitter Bootstrap and an special optionable view.
This is the default view.
<?php
use Pagerfanta\View\DefaultView;
$view = new DefaultView();
$options = array('proximity' => 3);
$html = $view->render($pagerfanta, $routeGenerator, $options);
Options (default):
- proximity (3)
- previous_message (Previous)
- next_message (Next)
- css_disabled_class (disabled)
- css_dots_class (dots)
- css_current_class (current)
- dots_text (...)
- container_template (%pages%)
- page_template (%text%)
- span_template (%text%)
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;
}
This view generates a pagination for Twitter Bootstrap.
<?php
use Pagerfanta\View\TwitterBootstrapView;
$view = new TwitterBootstrapView();
$options = array('proximity' => 3);
$html = $view->render($pagerfanta, $routeGenerator, $options);
Options (default):
- proximity (3)
- prev_message (← Previous)
- prev_disabled_href ()
- next_message (Next →)
- next_disabled_href ()
- dots_message (…)
- dots_href ()
- css_container_class (pagination)
- css_prev_class (prev)
- css_next_class (next)
- css_disabled_class (disabled)
- css_dots_class (disabled)
- css_active_class (active)
This view is to reuse options in different views.
<?php
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!!'));
