http://lawcommission.gov.np/site/NepalLawCommissionFinal/NepalLawCommissionFinal/document.php?cat=112&sub_cat=10008

你们可以建议一种方式来展示有限的没有。一页中的pdf文件？

Answer 1

以下是您需要更改功能的方法：

public function list_doc($cat, $page=0) {
    $itemsPerPage = 20;
    $cat = intval($cat, 10);
    $start = intval($page, 10) * $itemsPerPage;
    if ($start < 0) $start = 0;

    $qry = $this->dbobj->db1->prepare("SELECT SQL_CALC_FOUND_ROWS *
        FROM tbl_documents, tbl_cat_head_doc
        WHERE tbl_cat_head_doc.Cat_Id = " . $cat ." AND
        tbl_cat_head_doc.Doc_Id = tbl_documents.Doc_Id AND
        tbl_documents.Status = 'a'
        limit " . $start . "," . $itemsPerPage);
    return $qry;
}

并在主页调用函数中如下：

$lst = $base_obj->list_doc($id, $_GET['page']);

以防止下一个问题：请阅读SQL_CALC_FOUND_ROWS and FOUND_ROWS()

限制每页显示的项目数
