This is a quick implementation of a paginator for a project, (*1)
Installation
Simply require it with composer:, (*2)
composer require rgehan/paginator
Usage
define('ITEMS_PER_PAGE', 3);
// Gets the count of articles
$articlesCount = 10; // You might want to load that from the database
// Makes pagination
$paginator = new Paginator($articlesCount, self::ITEMS_PER_PAGE);
$paginator->setURLFormatString("http://localhost/articles?page=%d");
// Gets the page we want to access
if(isset($_GET['page']))
$page = $paginator->getValidPage($_GET['page']); // Returns a page in the range of the existing pages
else
$page = 0;
// Fetches the articles
$startIndex = $page * self::ITEMS_PER_PAGE;
$articles = do_sql_query("SELECT * FROM articles LIMIT " . $startIndex . ", " . ITEMS_PER_PAGE); // Pseudo-code for SQL query
// Creates the pagination
$pagination = $paginator->generateLinks($page);
/*
Let's say: $page = 2
Outputs:
[
[
'url' => 'http://localhost/articles?page=0',
'index' => 0,
'current' => false
],[
'url' => 'http://localhost/articles?page=1',
'index' => 1,
'current' => false
],[
'url' => 'http://localhost/articles?page=2',
'index' => 2,
'current' => true
],[
'url' => 'http://localhost/articles?page=3',
'index' => 3,
'current' => false
],
...
]
*/
You can then pass the output of $paginator->generateLinks($page) to your view and render your links as you wish., (*3)
