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

代码如下:

session_start(); 
$workid=$_GET[‘wid’];//获取工作号 
if($workid!=$_SESSION[‘$workid’]||$workid==”){ 
echo “”; 
} 
?> 

function.inc//主要包括数据库连接模块

代码如下:

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

代码如下:

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’];
?>

body{
font-family:Arial,Helvetica,sans-serif; /*设置字体样式*/
font-size:12px;
margin:0px 240px;
height:auto;
width:800px;
border:1px solid #006633;
background-color:rgb(195,245,200);

}

注销

echo “

入库

“;
echo “

出库

“;
?>

$query=”select * from storage where storage_id=’$stoid'”;//定位仓库信息
$result=mysql_query($query,$id);
if(mysql_num_rows($result)<1){
echo “没有仓库”.$stoid;
}else{
$info=mysql_fetch_array($result,MYSQL_ASSOC);
echo “仓库号:”.$stoid.” 总容量:”.$info[‘storage_cap’].” 剩余容量:”.$info[‘storage_lcap’].”
仓库地址:”.$info[‘storage_add’].” 仓库电话:”.$info[‘storage_tele’];
if (!mysql_select_db(“basicbase”,$id)){
die (“Can\’t select_db : ” . mysql_error());
}
//在basicbase中建立对应仓库货物视图，入库视图以及出库视图
//判断是否存在相关视图，没有的话就新建视图
$query=”select * from “.$stoid.”_inventory”;
if(!mysql_query($query,$id)){
//创建inventory视图
$query=”create view “.$stoid.”_inventory as
select inventory.goods_id,name,number from inventory,systembase.goods where storage_id=”.$stoid.” and inventory.goods_id=systembase.goods.goods_id”;
if(!mysql_query($query,$id)){
die (“Can\’t create_view_inventory : ” . mysql_error());
}
//创建input视图
$query=”create view “.$stoid.”_input as
select input_id,goods_id,number,time from input where admin_id=”.$workid;
if(!mysql_query($query,$id)){
die (“Can\’t create_view_input : ” . mysql_error());
}
//创建output视图
$query=”create view “.$stoid.”_output as
select output_id,goods_id,number,time from output where admin_id=”.$workid;
if(!mysql_query($query,$id)){
die (“Can\’t create_view_output : ” . mysql_error());
}
}
$query=”select * from “.$stoid.”_inventory”;
$result=mysql_query($query,$id);
if(mysql_num_rows($result)<1){
echo “
该仓库目前是空的”;
}else{
$totalnum=mysql_num_rows($result);
$pagesize=7;
$page=$_GET[“page”];
if(“”==$page){
$page=1;
}
$begin=($page-1)*$pagesize;
$totalpage=ceil($totalnum/$pagesize);

echo “

仓库中共有”.$totalnum.”种货物。”;
echo “每页”.$pagesize.”种，共”.$totalpage.”页。

“;
for($j=1;$j<=$totalpage;$j++){
echo “[“.$j.”] “;
}
echo “
“;
$query=”select *from “.$stoid.”_inventory order by goods_id limit $begin,$pagesize”;
$result=mysql_query($query,$id);
$datanum=mysql_num_rows($result);
//echo “

“;
echo “

“;
for($i=1;$i<=$datanum;$i++){
$info=mysql_fetch_array($result,MYSQL_ASSOC);
//echo “

“;
echo “

“;
}

}
}
mysql_close($id);
?>

货物id	货物名称	货物数量
货物id	货物名称	货物数量
“.$info[‘goods_id’].”	“.$info[‘name’].”	“.$info[‘number’].”
“.$info[‘goods_id’].”	“.$info[‘name’].”	“.$info[‘number’].”
