Ruwork Paginator
Description
This library provides a convenient way to paginate any data structure., (*1)
Some definitions:
- A section
is a set of pages, rendered together.
- Proximity
is a number of pages, displayed before and after the current page., (*2)
For example, for 10 pages with proximity 2 and current page 5 paginator will have 3 sections with the following page numbers: [1], [3, 4, 5, 6, 7], [10]
., (*3)
When the current page is close to one of the edges sections get merged., (*4)
Controller code example
<?php
use Ruwork\Paginator\PaginatorBuilder;
use Ruwork\Paginator\Provider\IterableProvider;
$data = range(1, 100);
$paginator = PaginatorBuilder::create()
// required
->setProvider(new IterableProvider($data))
// defaults to 1
// when out of range of estimated pages, PageOutOfRangeException is thrown
->setCurrent(2)
// defaults to 2
->setProximity(1)
// defaults to 10
->setPerPage(3)
->getPaginator();
// template logic
foreach ($paginator->getItems() as $item) {
// render the item row
}
if (null !== $previous = $paginator->getPrevious()) {
echo sprintf('<a href="?page=%d">Previous</a>', $previous->getNumber());
}
foreach ($paginator as $section) {
foreach ($section as $page) {
echo sprintf('<a href="?page=%1$d" class="%2$s">%1$d</a>', $page->getNumber(), $page->isCurrent() ? 'active' : '');
}
}
if (null !== $next = $paginator->getNext()) {
echo sprintf('<a href="?page=%d">Next</a>', $next->getNumber());
}
Data providers
IterableProvider
Can be used with an array
or an object implementing \Traversable
., (*5)
DoctrineOrmProvider
Can be used to paginate over Doctrine entities. Internally uses the native Doctrine\ORM\Tools\Pagination\Paginator
helper., (*6)
<?php
use Ruwork\Paginator\PaginatorBuilder;
use Ruwork\Paginator\Provider\DoctrineOrmProvider;
use Doctrine\ORM\EntityRepository;
/** @var EntityRepository $repository */
$qb = $repository->createQueryBuilder('entity')
->andWhere('entity.id = :id')
->setParameters([
'id' => 1
]);
$paginator = PaginatorBuilder::create()
->setProvider(new DoctrineOrmProvider($qb))
->getPaginator();
Custom
Create your own provider by implementing the Ruwork\Paginator\Provider\ProviderInterface
., (*7)
