README

Helps partition items across pages and generates sets of convenient controls for navigation

Requirements

• PHP 5.6.0+

Installation

1. Include the library via Composer [?]:

   $ composer require delight-im/pagination

2. Include the Composer autoloader:

   require __DIR__ . '/vendor/autoload.php';

Usage

Creating an instance

$numberOfItems = 1000;
$pagination = new Pagination($numberOfItems);

// or

$numberOfItems = 1000;
$itemsPerPage = 30;
$pagination = new Pagination($numberOfItems, $itemsPerPage);

// or

$numberOfItems = 1000;
$itemsPerPage = 30;
$currentPage = 10;
$pagination = new Pagination(
    $numberOfItems,
    $itemsPerPage,
    $currentPage
);

If you don’t specify the current page explicitly in the third argument, it will be auto-detected from the page or p query parameters, if available.

Displaying a pagination bar

Simple HTML

$targetUrl = '/products/drinks/?page={page}';
echo $pagination->toHtml($targetUrl);

// or

$targetUrl = '/products/drinks/?page={page}';
$numberOfControls = 11;
$showFirstLast = true;
$showPreviousNext = true;
$previousLabel = '« Previous';
$nextLabel = 'Next »';
echo $pagination->toHtml(
    $targetUrl,
    $numberOfControls,
    $showFirstLast,
    $showPreviousNext,
    $previousLabel,
    $nextLabel
);

Bootstrap front-end framework

$targetUrl = '/products/drinks/?page={page}';
echo $pagination->toHtmlForBootstrap5($targetUrl);

// or

$targetUrl = '/products/drinks/?page={page}';
$displaySize = 0; // -1 = small, 0 = normal, +1 = large
$numberOfControls = 11;
$showFirstLast = true;
$showPreviousNext = true;
$previousLabel = '« Previous';
$nextLabel = 'Next »';
echo $pagination->toHtmlForBootstrap5(
    $targetUrl,
    $displaySize,
    $numberOfControls,
    $showFirstLast,
    $showPreviousNext,
    $previousLabel,
    $nextLabel
);

Instead of Pagination#toHtmlForBootstrap5, you can also call Pagination#toHtmlForBootstrap4 or Pagination#toHtmlForBootstrap3 with the same method signature.

Custom HTML

First, generate an array of PaginationElement objects:

$controls = $pagination->build();

// or

$numberOfControls = 11;
$showFirstLast = true;
$showPreviousNext = true;
$previousLabel = '« Previous';
$nextLabel = 'Next »';
$controls = $pagination->build(
    $numberOfControls,
    $showFirstLast,
    $showPreviousNext,
    $previousLabel,
    $nextLabel
);

Then turn these PaginationElement objects into custom HTML:

foreach ($controls as $control) {
    // $control->getLabel();
    // $control->getPage();
    // $control->isSelected();
    // $control->isDisabled();
}

Adjusting database queries

$pagination->getOffset();
// int(1000)

$pagination->getLimit();
// int(25)

You can use these two values in your database queries, for example like this:

$sql = "SELECT * FROM products LIMIT " . $pagination->getOffset() . ", " . $pagination->getLimit();

// or

$sql = "SELECT * FROM products LIMIT " . $pagination->getLimit() . " OFFSET " . $pagination->getOffset();
