PHP表单提交不同数据到数据库的不同表的不同字段怎么实现？

你可以用 PHP 的 MySQLi 或 PDO 库来实现。

首先，你需要使用这些库中的函数连接数据库，然后把表单中的字段值插入到相应的数据表中。

例如，如果你使用 MySQLi，你可以这样写：

$conn = mysqli_connect("hostname", "username", "password", "database_name")

$rwid = $_POST['rwid']

$rwdj = $_POST['rwdj']

$rwzb = $_POST['rwzb']

$sql1 = "INSERT INTO table_a (s) VALUES ('$rwid')"

mysqli_query($conn, $sql1)

$sql2 = "INSERT INTO table_b (d) VALUES ('$rwdj')"

mysqli_query($conn, $sql2)

$sql3 = "INSERT INTO table_c (f) VALUES ('$rwzb')"

mysqli_query($conn, $sql3)

如果你使用 PDO，你可以这样写：

$conn = new PDO("mysql:host=hostnamedbname=database_name", "username", "password")

$rwid = $_POST['rwid']

$rwdj = $_POST['rwdj']

$rwzb = $_POST['rwzb']

$stmt1 = $conn->prepare("INSERT INTO table_a (s) VALUES (:s)")

$stmt1->bindParam(':s', $rwid)

$stmt1->execute()

$stmt2 = $conn->prepare("INSERT INTO table_b (d) VALUES (:d)")

$stmt2->bindParam(':d', $rwdj)

$stmt2->execute()

$stmt3 = $conn->prepare("INSERT INTO table_c (f) VALUES (:f)")

$stmt3->bindParam(':f', $rwzb)

$stmt3->execute()

希望这个答案对你有帮助。

写2个配置

oracle一个配置 mysql一个配置

当你想用oracle的时候调用oracle的配置

当你想用mysql的时候调用mysql的配置

serial_number.txt的示例内容：

serial_number.txt：

DM00001A11 0116,

SN00002A11 0116,

AB00003A11 0116,

PV00004A11 0116,

OC00005A11 0116,

IX00006A11 0116,

创建数据表：

create table serial_number(

id int primary key auto_increment not null,

serial_number varchar(50) not null

)ENGINE=InnoDB DEFAULT CHARSET=utf8

php代码如下：

$conn = mysql_connect('127.0.0.1','root','') or die("Invalid query: " . mysql_error())

mysql_select_db('test', $conn) or die("Invalid query: " . mysql_error())

$content = file_get_contents("serial_number.txt")

$contents= explode(",",$content)//explode()函数以","为标识符进行拆分

foreach ($contents as $k =>$v)//遍历循环

{

$id = $k

$serial_number = $v

mysql_query("insert into serial_number (`id`,`serial_number`)

VALUES('$id','$serial_number')")

}

备注：方法有很多种，我这里是在拆分txt文件为数组后，然后遍历循环得到的数组，每循环一次，往数据库中插入一次。

再给大家分享一个支持大文件导入的
