Installation

It's recommended to use the dependency manager Composer to install rayne/pagination.

composer require rayne/pagination

Features

• Implementation of the Search Pagination Pattern defined by Yahoo

  • One or zero indexed pages

  • Extracts safe page numbers from arbitrary user inputs, e.g. first or last page on invalid input or when being out of bounds

• Implementation of the Filter Pagination Pattern defined by Yahoo

  (This pattern is currently not officially supported but the code is ready for playing around)

• No dependencies (except the ones for testing)

• Framework-agnostic

  • No markup (but Bootstrap examples in /examples)

  • No template engine (but Twig examples in /examples)

  • No database backend (but offset and limit provided)

  • No URL builder

Usage

SearchPagination

1. Retrieve item count $totalItems

2. Let Rayne\Pagination calculate the offset

   $pagination = new SearchPagination(
       $totalItems,
       $itemsPerPage,
       $currentPage,
       $pagePadding = 4, 
       $isZeroBased = false
   );

3. Verify $currentPage with $pagination->isOnValidPage() or retrieve the requested items with the help of $pagination->getItemOffset() and $pagination->getItemLimit()

4. Render results and controls with the help of $pagination or $pagination->toArray() and the example templates in the /examples directory

Read the Examples section for examples and ideas.

SearchPaginationFactory

Instead of creating the SearchPaginationInterface implementation by hand a configurable factory can be used to provide the pagination as a service.

1. Either create a new factory (useful when working with a DI system) …

   $factory = new SearchPaginationFactory;

   … or initialize/fetch the global one

   $factory = SearchPaginationFactory::instance();

   The defaults are: one-indexed pages, 20 items per page and a page padding of 4.

2. Configure the factory (or skip this step)

   $factory->setIsZeroBased(true);
   $factory->setItemsPerPage(25);
   $factory->setPagePadding(2);

3. Build a new SearchPagination object

   $totalItems = 123;
   $currentPage = 2;
   $pagination = $factory->build($totalItems, $currentPage);

FilterPagination

The filter pagination pattern is not officially supported but feel free to play around with the following classes:

Rayne\Pagination\Filter\FilterPage
Rayne\Pagination\Filter\FilterPages
Rayne\Pagination\Filter\FilterPagination

Examples

The following examples are part of the /examples directory.

• Complete example (/examples/index.php)

• Simple (highlights current page) and advanced (highlights current page, hides redundant pagination controls) examples

  • PHP snippets (/examples/PHP)

  • Twig macros (/examples/Twig)

• The Twig macros are Bootstrap Framework compatible

Tests

1. Clone the repository

   git clone https://github.com/rayne/pagination.git

2. Install the development dependencies
