Как говорится в названии, у меня есть этот код для пользовательской таблицы с разбиением на страницы. Но моя ошибка заключается в том, что она не перенаправляется на число подкачки (всегда результат страницы 1). Мой код:
add_filter( 'the_content', 'get_scrapy_scraped' ); function get_scrapy_scraped( $content ) { include_once('paginator.class.php'); global $wpdb; if ( ! is_page( 'jobs' ) ) //when jobs is read return $content; $query = "SELECT COUNT(*) FROM wp_careers"; $result = mysql_query($query) or die(mysql_error()); $num_rows = mysql_fetch_row($result); $pages = new Paginator; $pages->items_total = $num_rows[0]; $pages->mid_range = 9; // Number of pages to display. Must be odd and > 3 $pages->paginate(); echo $pages->display_pages(); echo "<span class=\"\">".$pages->display_jump_menu().$pages->display_items_per_page()."</span>"; $query = "SELECT * FROM wp_careers ORDER BY Job_Name ASC $pages->limit"; $result = mysql_query($query) or die(mysql_error()); echo "<table>"; echo "<tr><th>Job Name</th><th>Department/Location</th><th>Information</th><th>Apply Links</th></tr>"; while($row = mysql_fetch_row($result)) { echo "<tr><td>$row[3]</td><td>$row[1]</td><td>$row[0]</td><td>$row[2]</td></tr>\n"; } echo "</table>"; echo $pages->display_pages(); echo "<p>Page: $pages->current_page of $pages->num_pages</p>\n"; echo "<p>SELECT * FROM table $pages->limit (retrieve records $pages->low-$pages->high from table - $pages->items_total item total / $pages->items_per_page items per page)"; } и paginator.class.php:
