1.conn.php
代码如下:
<?
$host="localhost"; //数据库服务器名称
$user="root"; //用户名
$pwd="1721"; //密码
$conn=mysql_connect($host,$user,$pwd);
mysql_query("SET
character_set_connection=gb2312,
character_set_results=gb2312,
character_set_client=binary",$conn);
if ($conn==FALSE)
{
echo "<center>服务器连接失败！<br>请刷新后重试。</center>";
return true;
}
$databasename="database";//数据库名称
do
{
$con=mysql_select_db($databasename,$conn);
}while(!$con);
if ($con==FALSE)
{
echo "<center>打开数据库失败！<br>请刷新后重试。</center>";
return true;
}
?>
2.upload.php
代码如下:
<?php
if ($_GET['action'] == "save"){
include_once('conn.php');
include_once('uploadclass.php');
$title=$_POST['title'];
$pic=$uploadfile;
if($title == "")
echo"<Script>window.alert('对不起！你输入的信息不完整!');history.back()</Script>";
$sql="insert into upload(title,pic) values('$title','$pic')";
$result=mysql_query($sql,$conn);
//echo"<Script>window.alert('信息添加成功');location.href='upload.php'</Script>";
}
?>
<html>
<head>
<title>文件上传实例</title>
</head>
<body>
<form method="post" action="?action=save" enctype="multipart/form-data">
<table border=0 cellspacing=0 cellpadding=0 align=center width="100%">
<tr>
<td width=55 height=20 align="center"> </TD>
<td height="16">
<table width="48%" height="93" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>标题：</td>
<td><input name="title" type="text" id="title"></td>
</tr>
<tr>
<td>文件： </td>
<td><label>
<input name="file" type="file" value="浏览" >
<input type="hidden" name="MAX_FILE_SIZE" value="2000000">
</label></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" value="上 传" name="upload"></td>
</tr>
</table></td>
</tr>
</table>
</form>
</body>
</html>
3.uploadclass.php
代码如下:
<?php
$uploaddir = "upfiles/";//设置文件保存目录 注意包含/
$type=array("jpg","gif","bmp","jpeg","png");//设置允许上传文件的类型
$patch="upload/";//程序所在路径
//获取文件后缀名函数
function fileext($filename)
{
return substr(strrchr($filename, '.'), 1);
}
//生成随机文件名函数
function random($length)
{
$hash = 'CR-';
$chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
$max = strlen($chars) - 1;
mt_srand((double)microtime() * 1000000);
