此页面与表格中的查询结果完美地加载。分页已到位，并且已按正确数量划分每个记录的页数。页面上还有其他与表无关的项目。当我尝试转到第二页时，我只获得没有其他记录的标题行，而其他信息显示在页面上作为未定义的索引，几乎就像首先没有查询一样。我在网上搜索了答案，我已经筋疲力尽了解解决这个问题的有限知识。我想要做的就是从mysql数据库中分页查询结果，并且只在每次用户更改页面时刷新表。我已经看过ajax和jquery来做这个但是无法处理在我的代码中实现它的内容和方法。我可以理解页面刷新问题，但我会假设分页无论如何都会有效。以下是我所拥有的代码，如果有人可以指出任何错误或建议如何最好地完成这项工作，我将非常感激。

答案 0 :(得分：0)
你有很多冗余代码，所以我先清理它，看它是否与问题有关。
第一个问题： $page上有太多的分配和检查
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$page=mysql_real_escape_string($page);
$page = $_GET['page'];
if($page)
$start = ($page - 1) * $limit;
else
$start = 0;
if ($page == 0) $page = 1;
例如应该是：
$page = isset($_GET['page']) ? max((int)$_GET['page'], 1) : 1;
$start = ($page - 1) * $limit;
现在你不必检查它是否已设置，0等等。
第二个问题：我看不到您在使用其他$_GET或$_SESSION变量的位置，但如果您希望通过分页保留它们，则可以如果没有设置，请在分页网址中添加或使用emtpy $_GET变量覆盖会话。
