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

<html>

            $(function(){
                $('#time').datetimepicker({
                                dateFormat: 'yy-mm-dd',
                                timeFormat: "HH:mm:ss "
                                    });
                                    minDate: getFormattedDate(new Date())
                                    function getFormattedDate(date) {
    var day = date.getDate();
    var month = date.getMonth() + 1;

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.
