输出变量

Question

我正在创建一个管理页面，管理员可以在其中添加特定电影和特定影院的节目。管理员可以添加节目，剧院名称和电影名称。

这是一些代码..

<?php
$showdatetime=$_POST['showdatetime'];
$movieid=$_POST['movieid'];
$theaterid=$_POST['theaterid'];
if(empty($showdatetime)){  
echo  "Show time is a must";
}
else
{
$querycinema=mysql_query("SELECT show.show_datetime, show.theater_id, show.movie_id, theater.theater_name, movie.movie_name FROM `show` 
                        JOIN theater ON theater.theater_id = show.theater_id
                        JOIN movie ON movie.movie_id = show.movie_id                            
                        WHERE  show.show_datetime='$showdatetime' AND show.theater_id='$theaterid' AND show.movie_id='$movieid' ");
 $checkcinema=mysql_num_rows($querycinema);
if($checkcinema != 0)
{ 
echo "Sorry, ".$showdatetime." is already been scheduled for movie".$movieid." in theater ".$theaterid."."; 
}
else
{
 $insert_user=mysql_query("INSERT INTO `show` (show_datetime, movie_id, theater_id) VALUES ('$showdatetime','$movieid', '$theaterid')");

它的工作正常，但我有一个问题

 echo "Sorry, ".$showdatetime." is already been scheduled for movie".$movieid." in theater ".$theaterid."."; }

我需要一种方法来添加电影名称和剧院名称以供剧院和电影选择cz最好向管理员显示名称而不是剧院和电影的ID。

我希望很清楚.. 谢谢

Answer 1

您的查询结果集中已经有电影名称，所以请阅读：

if($checkcinema != 0)
{ 
    $data = mysql_fetch_assoc($querycinema);
    echo "Sorry, ".$showdatetime." is already been scheduled for movie".$data['movie_name']." in theater ".$theaterid."."; 
}

Answer 2

只需为您的数组添加价值$data['theather_name']＆amp; $data['movie_id']
