php小型企业库存管理系统的设计与实现代码
双专业毕业论文做了一个小型企业库存管理系统，使用PHP&mysql组合进行开发。头一次开发稍微大一点的东西，php也是自学的。这里想跟大家一起分享一下
check_login 模块
<!--用户登陆检验模块-->
<?php
session_start();
$workid=$_GET['wid'];//获取工作号
if($workid!=$_SESSION['$workid']||$workid==''){
echo "<script language=javascript>alert('您还没有登陆，无法管理!');location.href='login.php';</script>";
}
?>
function.inc//主要包括数据库连接模块
<?php
function mysql_link($user="admin",$password="admin",$database="systembase"){
$id=mysql_connect("localhost",$user,$password);
if(!$id){
die('Could not connect: ' . mysql_error());
}
if (!mysql_select_db($database,$id)){
die ("Can\'t select_db : " . mysql_error());
}
//改变客户端字符集编码为gb2312
mysql_query("SET NAMES gb2312");
return $id;
}
?>
仓库管理界面storage.php
<!--仓库管理员管理界面-->
2 <?php
3 include "inc/check_login.php";
4 include "inc/function.inc";
5 $id=mysql_link("storage","storage");//建立storage连接
6
7 $query="select * from admin where admin_id='$workid'";//定位仓库
8 $result=mysql_query($query,$id);
9 $info=mysql_fetch_array($result,MYSQL_ASSOC);
$stoid=$info['storage_id'];
?>

代码太多不一一贴了，第一次写碰到很多问题，但不管怎么说程序还是运行起来了
