如何在销售后更新库存表

时间：2014-10-30 10:09:49

标签： php mysql

我创建了一个库存管理系统，我无法弄清楚如何将库存表与销售表联系起来，以便在销售时更新库存表中的产品。我正在使用MySql

这里是sold.php，当我销售产品时，此页面会在销售表中保存记录，但我想更新manuf table qtyleft row。

    <?php require_once('../Connections/bidco.php'); ?>

<?php
mysql_select_db($database_bidco, $bidco);
$query_rsSaletype = "SELECT * FROM saletype ORDER BY type ASC";
$rsSaletype = mysql_query($query_rsSaletype, $bidco) or die(mysql_error());
$row_rsSaletype = mysql_fetch_assoc($rsSaletype);
$totalRows_rsSaletype = mysql_num_rows($rsSaletype);

mysql_select_db($database_bidco, $bidco);
$query_rsCustomercategory = "SELECT * FROM buyertype ORDER BY type ASC";
$rsCustomercategory = mysql_query($query_rsCustomercategory, $bidco) or die(mysql_error());
$row_rsCustomercategory = mysql_fetch_assoc($rsCustomercategory);
$totalRows_rsCustomercategory = mysql_num_rows($rsCustomercategory);

mysql_select_db('invmgt', mysql_connect('localhost','root','dream2014')) or die(mysql_error());
?>
<?php
    //Start session
    session_start();    
    //Unset the variables stored in session
    unset($_SESSION['SESS_ID']);
    unset($_SESSION['SESS_Username']);
    unset($_SESSION['SESS_Name']);
?>
<?php
if (isset ($_POST ['Submit']))
{
$da=date("Y-m-d");
$itemname=$_POST['itemname'];
$itemcode=$_POST['itemcode'];
$itemtype=$_POST['itemtype'];
$price=$_POST['unitprice'];
$quantity=$_POST['quantity'];
$ttype=$_POST['select2'];
$ccat=$_POST['select'];
$idate=date("Y-m-d");

mysql_query("INSERT INTO sold_goods (itemname, itemcode, itemtype, unitprice, quantity, transactiontype, customercategory, Date) VALUES ('$itemname', '$itemcode', '$itemtype', '$unitprice', '$quantity', '$ttype', '$ccat', '$idate')");

header("location:sold.php");
 }                      

 ?>

<?php
mysql_free_result($rsSaletype);

这是用于添加新股票的manuf.php 

    <?php require_once('../Connections/bidco.php'); ?>
<?php
if (isset ($_POST ['Submit']))
{
$da=date("Y-m-d");
$itemname=$_POST['itemname'];
$itemcode=$_POST['itemcode'];
$itemtype=$_POST['itemtype'];
$unitprice=$_POST['unitprice'];
$quantity=$_POST['quantity'];
$idate=date("Y-m-d");

mysql_query("INSERT INTO manuf (itemname, itemcode, itemtype, price, qtyleft, Date) VALUES ('$itemname', '$itemcode', '$itemtype', '$unitprice', '$quantity', '$idate')");

header("location:manuf.php");
 }                      

 ?>

插入sold表后，也要更新manf表：

mysql_query("INSERT INTO sold_goods 
                 (itemname, itemcode, itemtype, unitprice, quantity,
                 transactiontype, customercategory, Date)
                 VALUES 
                 ('$itemname', '$itemcode', '$itemtype', '$unitprice', 
                '$quantity', '$ttype', '$ccat', '$idate')");



 mysql_query("UPDATE manuf SET qtyleft = qtyleft - $quantity where
 itemcode = '$itemcode'" );
