Drupal 7 Display array contents with pager

This example shows how to generate a render array from an array of data that includes a pager. This example will theme the content as an item_list, but the content section could be parsed and rendered as a table or by any other means, depending on the content of the $rows array.

The trick to using theme_pager(), as I discovered, is that (under normal circumstances and typical usage) it gets all of its information from pager_default_initialize(). The output selection is handled by the PHP array_slice() function.

/** * Page callback for some paged data. */ function mysite_some_paged_data() { $output = NULL; $rows = mysite_generate_a_big_array(); if (!empty($rows)) { $limit = 20; $page = pager_default_initialize(count($rows), $limit, 0); $offset = $limit * $page; $output = array( array( '#theme' => 'item_list', '#items' => array_slice($rows, $offset, $limit), ), array( '#theme' => 'pager', ), ); } }
