Question

我有这样的HTML格式：

<html>
    <head>
    <body>
        <form action='upload_data.php' method="POST" enctype="multipart/form-data">
            <input type="text" name="total_container">
            <button id="submit">Add</button>    
        </form>
    </body>
    </head>
</html>

upload_data.php

include 'connect.php';
$total_container = $_POST["total_container"];

if (!empty($total_container)){
    $fill="INSERT INTO `container`(`total_container`, `time`)VALUES($total_container,'blabla')";
    $data=mysql_query($fill);
    if(isset($data)){
        echo "<script>alert ('Great');</script>";
    } else {
        echo "<script>alert('No...');</script>";
    }
}

我想填充我的数据库表（容器），如下所示：

id_block  | total_container | time     |
---------------------------------------
1         | 1               | 00:00:20 |
2         | 2               | 00:00:40 |
3         | 3               | 00:01:00 |
4         | 6               | 00:02:00 |

id_block是auto_increment
对于每个total_container，它乘以20秒的时间字段。

所以，我应该在查询中做什么？，我想自动填充时间字段，乘以20秒。

Answer 1

试试这个

INSERT INTO `container`(`total_container`, `time`) 
VALUES($total_container, SEC_TO_TIME($total_container*20) )

请参阅SEC_TO_TIME

的参考资料

Answer 2

更改您的代码：

<?php
include 'connect.php';
$total_container = $_POST["total_container"];
$time = date("H:i:s", $total_container);
if (!empty($total_container)){
$fill="INSERT INTO `container`(`total_container`, `time`)VALUES($total_container,'$time ')";
$data=mysql_query($fill);
if(isset($data))
            {
                echo "<script>alert ('Great');</script>";
            }
            else
            {
                echo "<script>alert('No...');</script>";
                        }
}

?>

Answer 3

<?php
$timeRaw = $total_container * 20;
$time = gmdate("H:i:s", $timeRaw);
$fill="INSERT INTO `container`(`total_container`, `time`)VALUES($total_container,'$time')";
?>

希望它适合你。

Answer 4

首先，始终转义您从用户收到的数据，因为您正在使用旧的MySQL扩展。否则，您将对SQL注入开放。

这是一个构建正确SQL查询的代码（我省略了对empty($total_container)的检查以便更好地理解）。

//Get data from user and escape
$total_container=mysql_real_escape_string($_POST['total_container']);
//Calculate time in seconds * 20
$time_in_seconds=$total_container*20;
//format as hh:mm:ss.
//Using gmdate('H:i:s',$time_in_seconds) for this is ok,
//but only if your $time_in_seconds is never going to exceed 24 hours
$time=sprintf('%02d:%02d:%02d', 
      ($time_in_seconds/3600), ($time_in_seconds/60%60), $time_in_seconds%60);
//build SQL query
$fill="INSERT INTO `container` (`total_container`, `time`)
       VALUES($total_container,'$time')";

Answer 5

添加

$time = $total_container*20; $time = '00:00:'.$time;

并将查询编辑为

$fill="INSERT INTO `container`(`total_container`, `time`) 
       VALUES ($total_container,'$time')";

您也可以使用gmdate("H:i:s", $time);代替$time = '00:00:'.$time; 您使用的方法取决于表结构。如果时间是文本提交，您可以同时使用两者。但如果时间是一个时间字段，那么最好使用第二个例子（gmdate）。
