Pagination¶
Note
Pagination via Fluid widgets will be removed in TYPO3v11, see Breaking: #92529 - All Fluid widget functionality removed. Use the API documented here to implement your own pagination.
The TYPO3 core provides an interface to implement the native pagination of lists like arrays or query results of Extbase.
The foundation of that new interface \TYPO3\CMS\Core\Pagination\PaginatorInterface is that
it's type agnostic. It means, that it doesn't define the type of paginatable objects. It's up to the
concrete implementations to enable pagination for specific types. The interface only forces you to
reduce the incoming list of items to an iterable sub set of items.
Along with that interface, an abstract paginator class \TYPO3\CMS\Core\Pagination\AbstractPaginator
is available that implements the base pagination logic for any kind of Countable set of
items while it leaves the processing of items to the concrete paginator class.
Two concrete paginators are available:
For type
array:\TYPO3\CMS\Core\Pagination\ArrayPaginatorFor type
\TYPO3\CMS\Extbase\Persistence\QueryResultInterface:\TYPO3\CMS\Extbase\Pagination\QueryResultPaginator
Code-Example for the ArrayPaginator:
// use TYPO3\CMS\Core\Pagination\ArrayPaginator;
$itemsToBePaginated = ['apple', 'banana', 'strawberry', 'raspberry', 'pineapple'];
$itemsPerPage = 2;
$currentPageNumber = 3;
$paginator = new ArrayPaginator($itemsToBePaginated, $currentPageNumber, $itemsPerPage);
$paginator->getNumberOfPages(); // returns 3
$paginator->getCurrentPageNumber(); // returns 3, basically just returns the input value
$paginator->getKeyOfFirstPaginatedItem(); // returns 5
$paginator->getKeyOfLastPaginatedItem(); // returns 5
// use TYPO3\CMS\Core\Pagination\SimplePagination;
$pagination = new SimplePagination($paginator);
$pagination->getAllPageNumbers(); // returns [1, 2, 3]
$pagination->getPreviousPageNumber(); // returns 2
$pagination->getNextPageNumber(); // returns null
// …
