Available Adapters
The Pagerfanta package provides out-of-the-box support for a number of storage backends. Please review the installation guide for details on how to install optional packages.
Third Party
Adapters are provided for a number of third party storage solutions, allowing this package to be used in a variety of environments.
Doctrine
Adapters are available for a number of Doctrine packages.
Collections
The collections adapters are available with the pagerfanta/doctrine-collections-adapter
package for use with Doctrine Collections.
Below is an example of using the CollectionAdapter
on a collection from an entity.
<?php
use App\Entity\User;
use Doctrine\ORM\Configuration;
use Doctrine\ORM\EntityManager;
use Pagerfanta\Doctrine\Collections\CollectionAdapter;
$config = new Configuration();
$connection = [
'driver' => 'pdo_sqlite',
'memory' => true,
];
$em = EntityManager::create($connection, $config);
$user = $em->find(User::class, 1);
$adapter = new CollectionAdapter($user->getGroups());
Below is an example of using the SelectableAdapter
on a class which implements Doctrine\Common\Collection\Selectable
(such as a Doctrine\ORM\PersistentCollection
).
<?php
use App\Entity\User;
use Doctrine\Common\Collections\Criteria;
use Doctrine\ORM\Configuration;
use Doctrine\ORM\EntityManager;
use Pagerfanta\Doctrine\Collections\SelectableAdapter;
$config = new Configuration();
$connection = [
'driver' => 'pdo_sqlite',
'memory' => true,
];
$em = EntityManager::create($connection, $config);
$user = $em->find(User::class, 1);
$criteria = Criteria::create()->andWhere(Criteria::expr()->in('id', [1, 2, 3]));
$adapter = new SelectableAdapter($user->getGroups(), $criteria);
DBAL
The DBAL adapters are available with the pagerfanta/doctrine-dbal-adapter
package for use with Doctrine's DBAL.
The SingleTableQueryAdapter
is a helper class which is optimized for queries which do not have any join statements.
The class constructor requires a Doctrine\DBAL\Query\QueryBuilder
and the field name that should be counted (typically this will be your primary key).
Below is an example of using the SingleTableQueryAdapter
.
<?php
use Doctrine\DBAL\DriverManager;
use Pagerfanta\Doctrine\DBAL\SingleTableQueryAdapter;
$params = [
'driver' => 'pdo_sqlite',
'memory' => true,
];
$connection = DriverManager::getConnection($params);
$query = $connection->createQueryBuilder()
->select('p.*')
->from('posts', 'p');
$adapter = new SingleTableQueryAdapter($query, 'p.id');
The QueryAdapter
is the main adapter for use with the DBAL package, you should use this on queries that have join statements.
The class constructor requires a Doctrine\DBAL\Query\QueryBuilder
and a callable which can be used to modify a clone of the QueryBuilder
for a COUNT query. The callable should have a signature of function (QueryBuilder $queryBuilder): void {}
.
Below is an example of using the QueryAdapter
.
<?php
use Doctrine\DBAL\DriverManager;
use Doctrine\DBAL\Query\QueryBuilder;
use Pagerfanta\Doctrine\DBAL\QueryAdapter;
$params = [
'driver' => 'pdo_sqlite',
'memory' => true,
];
$connection = DriverManager::getConnection($params);
$query = $connection->createQueryBuilder()
->select('p.*')
->from('posts', 'p');
$countQueryBuilderModifier = static function (QueryBuilder $queryBuilder): void {
$queryBuilder->select('COUNT(DISTINCT p.id) AS total_results')
->setMaxResults(1);
};
$adapter = new QueryAdapter($query, $countQueryBuilderModifier);
MongoDB ODM
The MongoDB ODM adapter is available with the pagerfanta/doctrine-mongodb-odm-adapter
package for use with Doctrine' MongoDB ODM.
The class constructor requires a Doctrine\ODM\MongoDB\Query\Builder
.
Below is an example of using the QueryAdapter
.
<?php
use App\Document\Article;
use Doctrine\ODM\MongoDB\Configuration;
use Doctrine\ODM\MongoDB\DocumentManager;
use Pagerfanta\Doctrine\MongoDBODM\QueryAdapter;
$config = new Configuration();
$dm = DocumentManager::create(null, $config);
$query = $dm->createQueryBuilder(Article::class);
$adapter = new QueryAdapter($query);
ORM
The ORM adapter is available with the pagerfanta/doctrine-orm-adapter
package for use with Doctrine's ORM.
The class constructor requires either a Doctrine\ORM\Query
or Doctrine\ORM\QueryBuilder
instance. You can also specify whether to query join collections or use output walkers on the underlying Paginator
.
Below is an example of using the QueryAdapter
.
<?php
use App\Entity\User;
use Doctrine\ORM\Configuration;
use Doctrine\ORM\EntityManager;
use Pagerfanta\Doctrine\ORM\QueryAdapter;
$config = new Configuration();
$connection = [
'driver' => 'pdo_sqlite',
'memory' => true,
];
$em = EntityManager::create($connection, $config);
$repository = $em->getRepository(User::class);
$query = $repository->createQueryBuilder('u');
$adapter = new QueryAdapter($query);
PHPCR ODM
The PHPCR ODM adapter is available with the pagerfanta/doctrine-phpcr-odm-adapter
package for use with Doctrine's PHPCR ODM.
The class constructor requires a Doctrine\ODM\PHPCR\Query\Builder\QueryBuilder
.
Below is an example of using the QueryAdapter
.
<?php
use App\Document\Article;
use Doctrine\ODM\PHPCR\Configuration;
use Doctrine\ODM\PHPCR\DocumentManager;
use Pagerfanta\Doctrine\PHPCRODM\QueryAdapter;
$config = new Configuration();
$dm = DocumentManager::create($session, $config);
$query = $dm->createQueryBuilder()
->from(Article::class);
$adapter = new QueryAdapter($query);
Elastica
The Elastica adapter is available with the pagerfanta/elastica-adapter
package for use with Elastica.
<?php
use Elastica\Index;
use Elastica\Query;
use Elastica\Query\Term;
use Pagerfanta\Elastica\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 = Query::create(
new Term(
[
'name' => 'Fred',
]
)
);
$adapter = new ElasticaAdapter($searchable, $query);
$maxResults
parameter when constructing the ElasticaAdapter
. For more information, see https://github.com/whiteoctober/Pagerfanta/pull/213#issue-87631892.Solarium
The Solarium adapter is available with the pagerfanta/solarium-adapter
package for use with Solarium.
<?php
use Pagerfanta\Solarium\SolariumAdapter;
$query = $solarium->createSelect();
$query->setQuery('search term');
$adapter = new SolariumAdapter($solarium, $query);
First Party
There are also several "first party" adapters which are not dependent upon an external storage solution. All first party adapters are available with the pagerfanta/core
package.
Array
The ArrayAdapter
is used to paginate an array of items.
<?php
use Pagerfanta\Adapter\ArrayAdapter;
$adapter = new ArrayAdapter([]);
Callback
The CallbackAdapter
uses callable functions to process pagination.
The adapter takes two callables:
-
$nbResultsCallable
: A callable to count the number items in the list, the callable should have a signature offunction (): int {}
-
$sliceCallable
: A callable to get the items for the current page in the paginated list, the callable should have a signature offunction (int $offset, int $length): iterable {}
<?php
use Pagerfanta\Adapter\CallbackAdapter;
$adapter = new CallbackAdapter(
static fn (): int => 0,
static fn (int $offset, int $length): iterable => []
);
Concatenation
The ConcatenationAdapter
allows querying results from multiple adapters. It keeps the order of the given adapters and the order of their results.
<?php
use Pagerfanta\Adapter\ArrayAdapter;
use Pagerfanta\Adapter\ConcatenationAdapter;
$adapter = new ConcatenationAdapter(
[
new ArrayAdapter([]),
new ArrayAdapter([]),
]
);
Fixed Size
The FixedAdapter
takes a fixed data set and returns it no matter the request.
It is 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.
<?php
use Pagerfanta\Adapter\FixedAdapter;
$adapter = new FixedAdapter(5, ['boo', 'doo', 'foo', 'goo', 'moo']);
Null Values
The NullAdapter
generates a list of null values for the number of items specified, useful in a testing environment where you don't want to set up a database.
<?php
use Pagerfanta\Adapter\NullAdapter;
$adapter = new NullAdapter(5);
Transforming
The TransformingAdapter
is an adapter decorator which can be used to standardize the data from the wrapped adapter.
The transformer is a callable which accepts the item to be transformed and the key from the iterable, it should have a signature of function (mixed $item, int|string $key): mixed {}
<?php
use Pagerfanta\Adapter\ArrayAdapter;
use Pagerfanta\Adapter\TransformingAdapter;
$formatter = new \NumberFormatter('en', \NumberFormatter::SPELLOUT);
$adapter = new TransformingAdapter(
new ArrayAdapter(range(1, 100)),
static fn (int $item, int $key): string => $formatter->format($item)
);
