我有一个用 MySQL 准备的 PHP Web 应用程序，我决定通过 PDO 我遇到分页问题。
这是我的代码

这是在第一次运行时使用第一个结果集没有任何问题的工作，当我单击下一页时出现此错误
« ‹ Page 0 of 0 pages, displaying -19-0 of 0 results › »
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-20' at line 1
但是当我写时间变量manuel时
$time = '2013-08-01 00:00:00';
$time1 = '2013-09-01 00:00:00';
没有问题，一切都很完美，但是当我尝试使用 POST 方法通过 timepicker 获取时间时
$time = $_POST['time'];
$time1 = $_POST['time1'];
它失败。
等待你的伟大思想。
我已将偏移变量编辑为
$offset = max($page - 1, 0) * $limit;
不，结果是
当我点击下一页链接时，第一次运行它工作正常
« ‹ Page 0 of 0 pages, displaying 1-0 of 0 results › »
No results could be displayed.
