PHP-1个表单，2个表-Can'；t在表1中插入数据

我正在尝试制作一个发票系统，从教程中添加行，并将数据正确插入tbl_orderdetail，但我无法将数据插入tbl_order

以下是两个MYSQL表：

CREATE TABLE IF NOT EXISTS `tbl_order` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`re_name` varchar(255) DEFAULT NULL,
`location` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

---

这是我的连接代码：

<?php
$cn = mysql_connect('localhost','root','');
if($cn)
{
mysql_select_db('mydb',$cn);
}

if(isset($_POST['submit']))
$re_name = $_POST['re_name'];
$location = $_POST['location'];
{
mysql_query ("INSERT INTO tbl_order(re_name,location)        VALUES('{$_POST['re_name']}','{$_POST['location']}')");
$id = mysql_insert_id();
for($i = 0 ;$i < count($_POST['productname']);$i++)
{
    mysql_query("INSERT INTO tbl_orderdetail 
                SET order_id        = '{$id}', 
                    product_name    = '{$_POST['productname'][$i]}', 
                    quantity        = '{$_POST['quantity'][$i]}', 
                    price           = '{$_POST['price'][$i]}', 
                    discount        = '{$_POST['discount'][$i]}', 
                    amount          = '{$_POST['amount'][$i]}'
                ");
}
}
?>

谢谢大家对我的帮助。
我放弃了tbl_订单，创建了一个名为“奥卡门”的新订单

以下是有效的php代码：

if(isset($_POST['submit']))
{
$razao     = $_POST["razao"];
$local      = $_POST["local"];
$condicao     = $_POST["condicao"];
$estado         = $_POST["estado"];
$material       = $_POST["material"];
$obs        = $_POST["obs"];
mysql_query
("INSERT INTO orcamen ( id , razao , local , condicao , estado , material , obs ) 
        VALUES ( NULL , '$razao', '$local', '$condicao', '$estado', $material', '$obs')");
$id = mysql_insert_id();
for($i = 0 ;$i < count($_POST['productname']);$i++)
{
    mysql_query("INSERT INTO tbl_orderdetail 
                SET order_id        = '{$id}', 
                    product_name    = '{$_POST['productname'][$i]}', 
                    quantity        = '{$_POST['quantity'][$i]}', 
                    price           = '{$_POST['price'][$i]}', 
                    discount        = '{$_POST['discount'][$i]}', 
                    amount          = '{$_POST['amount'][$i]}'
                ");
}
}

if（isset（$\u POST['submit']））
{
$razao=$_POST[“razao”]；
$local=$_POST[“local”]；
$condico=$_POST[“condico”]；
$estado=$_POST[“estado”]；
$material=$_POST[“material”]；
$obs=$_POST[“obs”]；
mysql\u查询
（“插入奥卡门（id、razao、当地、康迪科、estado、材料、obs）
值（NULL、$razao'、$local'、$condicao'、$estado'、$material'、$obs'）；
$id=mysql_insert_id（）；
对于（$i=0；$i
发生了哪些错误？你还需要格式化你的代码。没有写的错误，但是唯一能得到我输入的表是tbl_orderdetail。表tbl_顺序始终为空。是否启用了错误报告？是的，@script47正在尝试使用Chrome Logger进行调试。您可以在chrome控制台上打印值
