Pager_Sliding is a class to page an array of data.
It is taken as input and it is paged according to various parameters.
Pager_Sliding also builds links within a specified range,
and allows complete customization of the output (it even works with mod_rewrite).
It is compatible with PEAR::Pager's API
Deprecated
This package is deprecated in favour of the new
Pager v.2.x.
Example 1
This simple example will page the array of alphabetical letters, giving back
pages with 3 letters per page, and links to the previous two / next two pages:
require_once 'Pager/Sliding.php';
$params = array(
'perPage' => 3,
'delta' => 2,
'itemData' => array('a','b','c','d','e',[...omissis...],'z')
);
$pager = & new Pager_Sliding($params);
$data = $pager->getPageData();
$links = $pager->getLinks();
//$links is an ordered+associative array with 'back'/'pages'/'next'/'first'/'last'/'all' links.
//NB: $links['all'] is the same as $pager->links;
//echo links to other pages:
echo $links['all']
//Show data for current page:
echo 'PAGED DATA: ' ; print_r($data);
//Results from methods:
echo 'getCurrentPageID()...: '; var_dump($pager->getCurrentPageID());
echo 'getNextPageID()......: '; var_dump($pager->getNextPageID());
echo 'getPreviousPageID()..: '; var_dump($pager->getPreviousPageID());
echo 'numItems()...........: '; var_dump($pager->numItems());
echo 'numPages()...........: '; var_dump($pager->numPages());
echo 'isFirstPage()........: '; var_dump($pager->isFirstPage());
echo 'isLastPage().........: '; var_dump($pager->isLastPage());
echo 'isLastPageComplete().: '; var_dump($pager->isLastPageComplete());
echo '$pager->range........: '; var_dump($pager->range);
In case you're wondering, $pager->range is a numeric array; its keys are the numbers of
the pages in the current range, and the matching values are booleans (TRUE if its key
represents currentPage, FALSE otherwise). This array can be useful to build the links
manually, e.g. when using a template engine.
Example 2
This example shows how you can use this class with mod_rewite.
Let's suppose we have a .htaccess like this:
