1个ID，以获取更多物品 [英] 1 id for more items

问题描述

我有一个request_form.php表单，用于管理请求项目的购买请求表单.

I have a form request_form.php, that is manage Purchase Request Form for request item.

Purchase_Request_No :(自动-自动递增)
日期:
部门:
供应商:
Item_Request:
例子有5行:
1.
2.
3.
4.
5.

Purchase_Request_No : (automatic - autoincrement)
Date :
Dept :
Supplier :
Item_Request :
Example have a 5 row :
1.
2.
3.
4.
5.

我想在一次购买请求中有1个Purchase_Request_No.
例子:

Purchase_Request_No:17
日期:2012年7月25日
部门:生产
供应商:Microsoft
Item_Request:
1.Windows XP Professional
2.键盘
3.鼠标
4.液晶显示器
5.扬声器

I want to make once Purchase Request have 1 Purchase_Request_No.
Example :

Purchase_Request_No : 17
Date :25-Jul-2012
Dept :Production
Supplier :Microsoft
Item_Request :
1.Windows XP Professional
2.Keyboard
3.Mouse
4.LCD Monitor
5.Speaker

那么，如果项目请求超过1个项目(在这种情况下，我放置了5个项目)，我如何用1个Purchase_Request_No来实现?

So, how can I make it with 1 Purchase_Request_No with item request more than 1 item(in this case I put 5 items)?

任何人都可以帮助我吗? 感谢您的进阶.

Anyone can help me ? Thanks for advance.

大家好，现在又回来，我已经在编写概念了. 它已成功将数据保存到数据库中，但是当插入5个项目时，仍会按ID为每个项目提交数据. 例子:
项目1-计算机(采购1)
项目2-鼠标(购买编号2)
我想要的是:
项目1-计算机(采购1)
项目2-鼠标(购买1)

Hi all, back again now I already in coding the concept. It's successfully save the data into database, but still when insert 5 item, it submit the data per item per ID. Example :
Item 1 - Computer (Purchase No 1)
Item 2 - Mouse (Purchase No 2)
That I wanted is :
Item 1 - Computer (Purchase No 1)
Item 2 - Mouse (Purchase No 1)

这是我的代码: 我使用自动购买的购买编号.

and here it's my code : I using purchase no with autoincrement.

<?php
$conn = oci_connect("system", "dev01");
$n = $_POST['jum'];
for ($i=1; $i<=$n; $i++)
{
$dept=$_POST['dept'];
$date_request=$_POST['date_request'];
$supplier=$_POST['supplier'];   

$item=$_POST['item'.$i];    
$qty=$_POST['qty'.$i];  
$uprice=$_POST['uprice'.$i];    
$total=$_POST['total'.$i];  

$s = oci_parse($conn,
"insert into purchase_request(dept_id, supplier_id, date_request, item, qty, uprice, total_amount) values ('$dept', '$supplier', '$date_request', '$item'
, '$qty', '$uprice', '$total'
)");

$r = oci_execute($s);

oci_rollback($conn);

echo "Data was committed\n";
}
?>

有什么主意吗?

推荐答案

具有三个表.一个将包含以下产品:

Have three tables. One would contain the products:

id    Product
1     Windows XP Professional
2     Keyboard
3     Mouse
4     LCD Monitor
5     Speaker

另一个包含请求:

id    request_date    dept       supplier
1     25-Jul-2012     Production Microsoft

第三个将前两个映射在一起

The third maps the first two together

id  request_id  item_id
1   1           1
2   1           2
3   1           3
4   1           4
5   1           5

(或者，您可以将商品的ID设为质数，并将items列存储为多个项目的倍数.您要做的就是找到items列的质因数，然后那么您就有了物品清单！*)

(Alternately, you could make the ids of the products prime numbers and store the items column as a multiple of the items. All you'd need to do is find the prime factors of the items column, and then you've got the list of items!*)

*由于某种原因，没有人认为这是个好主意.

*For some reason, no one at work thinks this is a good idea.
