Question

我想要实现的是按日期和时间订购表格（先是下午，然后是下午）。当我尝试使用此代码（ORDER BY reservationdate DESC，reservationtime ASC）时，这就是我得到的。

我对日期没有问题，但时间没有正确排序。我想要的是随时随地展示＆＃34; am＆＃34;首先是时间跟随＆＃34; pm＆＃34;。

这是我如何获取日期和时间并将其插入数据库

$reservationDate = date("F j, Y");
$reservationTime = date( g:i a"); 

$insertdata = "INSERT INTO reservations (reservationdate, reservationtime)VALUES('$reservationDate', '$reservationTime')";

这是显示它的代码

<?php
        $query = "SELECT * FROM reservations ORDER BY reservationdate DESC, reservationtime ASC LIMIT " . $this_page_first_result . ',' . $results_per_page;
        $search_result = filterTable($query);
?>

Answer 1

据推测，reservationtime存储为字符串而不是时间。您应该使用适当的存储方法。

您可以使用str_to_date()：

轻松投射

order by str_to_date(reservationtime, '%l:%i %p')

这将考虑am / pm。

按时间顺序排列
