【问题描述】：
请帮忙。我的表格是分页的。当我单击列标题时，对列进行 ASC 或 DESC 排序。很好，这对所有列都完成了。我的问题是，当我单击第二个或第三个页面或任何其他页面时，我在单击的页面上看不到同一列的排序项目的延续。它现在的作用是在单击的页面上显示排序项目的延续，但对于数组索引 0 列。
我的代码如下。您的帮助将不胜感激。我对这件事完全陌生。提前谢谢你。
我的代码：
<?php
require_once "db.php";
$columns = array('date', 'mname', 'amount');
$column = isset($_GET['column']) && in_array($_GET['column'], $columns) ? $_GET['column'] : $columns[0];
$sort_order = isset($_GET['order']) && strtolower($_GET['order']) == 'desc' ? 'DESC' : 'ASC';
$perpage = 5;
if(isset($_GET['page']) & !empty($_GET['page'])){
$curpage = $_GET['page'];
}else{
$curpage = 1;
}
$start = ($curpage * $perpage) - $perpage;
$PageSql = "SELECT * from `save`";
$pageres = mysqli_query($link, $PageSql);
$totalres = mysqli_num_rows($pageres);
$endpage = ceil($totalres/$perpage);
$startpage = 1;
$nextpage = $curpage + 1;
$previouspage = $curpage - 1;
$ReadSql = "select date, mname, saving from save ORDER BY $column $sort_order LIMIT $start, $perpage";
$result = mysqli_query($link, $ReadSql);
