插入两个或更多列并与一行相关-php-mysql

我有一张表格要填写那个人的性别和工作 如果任何人有两份或两份以上的工作，我如何将其添加到数据库中并与该人关联

如将驱动程序添加到列表中

<?php 
$insertjob = sprintf("INSERT INTO `user` (id, name, gender, job) VALUES (%s, %s, %s)",
                       GetSQLValueString($_POST['name'],   "text"),
                       GetSQLValueString($_POST['gender'], "text"),
                       GetSQLValueString($_POST['job'],    "text"));
?>

谢谢

您可以使用两张桌子

执行以下操作：

表1：人员

ID | Person | Sex

表2：工作

ID | Person_ID | Job

现在可以使用外键了。如果你有一个人，让我们给他起名叫杰克，说他有两份工作，你可以做以下事情：

亲临表：

ID | Name | Sex
1  | Jack | m

ID | Person_ID | Job

1  | 1         | Teacher

2  | 1         | Driver

在作业表中：

ID | Name | Sex
1  | Jack | m

ID | Person_ID | Job

1  | 1         | Teacher

2  | 1         | Driver

因此，您所要做的就是在yout Job表的

Person\u ID

字段中引用您的个人ID。然后，您可以简单地使用SQL连接

SELECT p.name, p.sex, j.job FROM Person p JOIN Jobs j ON p.id = j.Person_ID

您必须为

和

用户作业

创建单独的表，如：

强烈劝阻

或者您可以在

作业

列中转储

json\u encode（$\u POST['jobs']）

使用数组怎么样？考虑两个表并使用外键链接它们。考虑重新设计关于标准化的表，一对多关系创建一个单独的作业表，并使用外键将其连接到用户表。
