需要帮助修复我的分页。我限制每页显示5行，每次进入下一页时，它只更新底部的1行而不是每页显示5个新项目。
这是我现在拥有的。对不起，我发布了很长的代码。目前，我所做的解决方法是将$ listcount设置为1000，以显示同时禁用分页的所有项目。

答案 0 :(得分：2)
$curpageoffset = $_REQUEST['offset'];
应该是
$curpageoffset = $_REQUEST['offset']*$listcount-1;
目前您将开始位置增加，您应该按页数乘以限制（减去1）
答案 1 :(得分：0)
$totalpages = ceil($totalrows/$listcount);
if ($totalpages > '1') {
$curpageoffset = 0;
if (isset($_REQUEST['offset'])) {
if ($_REQUEST['offset'] >= $totalpages)
$curpageoffset = $totalpages - 1;
else if ($_REQUEST['offset']>0)
$curpageoffset = $_REQUEST['offset'];
}
$limitstr = " limit $curpageoffset,$listcount";
}
currentoffset，listcount，currentpage，totalpages，requestoffset
$currentPage = ceil($requestOffset/$listcount);
if ($currentPage > $totalpages) {$currentpage = 0;}
$currentoffset = $currentPage * $listcount;
然后
$limitstr = " limit $curpageoffset,$listcount";
