小型企业库存管理系统的设计与实现

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

View Code

1 <!-- 用户登陆检验模块 -->
2   <? php
3   session_start ();
4 $workid = $_GET [ ' wid ' ]; // 获取工作号
5 if ( $workid != $_SESSION [ ' $workid ' ] || $workid == '' ){
6 echo " <script language=javascript>alert('您还没有登陆，无法管理!');location.href='login.php';</script> " ;
7 }
8 ?>

function.inc//主要包括数据库连接模块

View Code

1 <? php
2 function mysql_link( $user = " admin " , $password = " admin " , $database = " systembase " ){
3 $id = mysql_connect ( " localhost " , $user , $password );
4 if ( ! $id ){
5 die ( ' Could not connect: ' . mysql_error ());
6 }
7 if ( ! mysql_select_db ( $database , $id )){
8 die ( " Can\'t select_db : " . mysql_error ());
9 }
10 // 改变客户端字符集编码为gb2312
11 mysql_query ( " SET NAMES gb2312 " );
12 return $id ;
13 }
14 ?>

仓库管理界面storage.php

View Code

1 <!-- 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);
10 $stoid = $info [ ' storage_id ' ];
11 ?>

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
