• thinkphp分页类使用,以及修改,添加了每页第一和最后的序号


    function index(){
    // 分页查询
    // 每页显示的记录数
    $limit = 5;
    // 获取总记录数量
    $total = $model->where($cond)->count();

    // 获取分页Page对象
    $page = new Page($total, $limit);

    // 完成查询
    $rows = $model
    ->where($cond)
    ->order($order)
    ->limit($page->firstRow . ', ' . $limit)
    ->select();
    $this->assign('rows', $rows);

    // 获取翻页的HTML代码
    // 配置显示
    $page->setConfig('header', '显示开始 %PAGE_START% 到 %PAGE_END% 之 %TOTAL_ROW% (总 %TOTAL_PAGE% 页)');
    $page->setConfig('theme', '<div class="col-sm-6 text-left"><ul class="pagination">%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%</ul></div> <div class="col-sm-6 text-right">%HEADER%</div>');
    $page->setConfig('prev', '<');
    $page->setConfig('next', '>');
    $page->setConfig('first', '|<');
    $page->setConfig('last', '>|');

    $page_html = $page->show();
    $this->assign('page_html', $page_html);
    }
