我想要實現的是按日期和時間排序(首先是pm,然後是pm)。當我用這段代碼嘗試它時(ORDER BY reservationdate DESC,reservationtime ASC),這就是我得到的。 按時間排序am和pm
我對日期沒有問題,但時間沒有正確排序。我想要的是先用「am」表示所有的時間,然後用「pm」跟着時間。
這裏是如何得到的日期和時間,並將其插入到數據庫
$reservationDate = date("F j, Y");
$reservationTime = date(g:i a");
$insertdata = "INSERT INTO reservations (reservationdate, reservationtime)VALUES('$reservationDate', '$reservationTime')";
這是代碼中顯示它
<?php
$query = "SELECT * FROM reservations ORDER BY reservationdate DESC, reservationtime ASC LIMIT " . $this_page_first_result . ',' . $results_per_page;
$search_result = filterTable($query);
?>

使用重複主題將日期和時間字符串轉換爲單個日期時間表達式,然後按該表達式進行排序。 – Shadow
