使用艾恩无组件上传类上传文件演示

使用艾恩无组件上传类来实现文件上传
访问原作者博客

一、建立一个表单存储图片路径到数据库

创建一个demo.asp文件，并在表单加入一个文本输入框用来存储图片地址。该输入框id为file1,name值为file1,然后使用iframe框架加载艾恩无组件上传类。使用时，iframe的src值指向艾恩无组件上传类upfile.asp，并传递一个id参数，这个id值为存放最终上传后文件路径的输入框id，这里为file1。

<!doctype html>
<html lang="en">
<head>
    <meta charset="GB2312">
    <title>使用艾恩无组件上传类上传文件演示</title>
</head>
<body>
    <form action="" method="post">
        <p><label for="file1" style="line-height:24px;display:inline-block;vertical-align:top;*display:inline;zoom:1;">图片路径：</label><input id="file1" name="file1" placeholder="请从右侧选择文件上传" style="height:18px;vertical-align:top;" /><iframe frameborder="0" height="24" width="400" name="upload" src="upfile.asp?id=file1" scrolling="no"></iframe></p>
    </form>
</body>
</html>

二、将下载的艾恩无组件上传类改名upfile.asp，并稍作修改，将上传后的文件路径写入通过id参数指定的文本框里。

<!doctype html>
<html lang="en">
<head>
    <meta charset="GB2312">
    <title>Document</title>
    <style>body,form{padding: 0;margin: 0;border: 0;}</style>
</head>

dim id
id=Request.QueryString("id")
if lcase(request.ServerVariables("REQUEST_METHOD"))="post" then
dim upload
set upload = new AnUpLoad
upload.Exe = "jpg|bmp|jpeg|gif|png" '允许上传的文件类型
upload.MaxSize = 2 * 1024 * 1024 '允许上传的最大文件大小，此处为2M
upload.GetData()
if upload.ErrorID>0 then
    response.Write upload.Description
else
    dim file,savpath,rootpath,servername,serverport
    rootpath = Server.MapPath("/")
    savepath = "/uploads/" '指定上传目录，此处指相对于根目录的文件夹路径
    servername = Request.ServerVariables("SERVER_NAME")
    serverport = Request.ServerVariables("SERVER_PORT")
    If serverport=443 then

    elseif serverport=80 then
        servername="http://" & servername
    else
        servername="http://" & servername & ":" & serverport
    end if
    set file = upload.files("file1")
    if file.isfile then
        result = file.saveToFile(rootpath&savepath,0,true)
        if result then
            msg = servername & savepath & file.filename
        else
            msg = file.Exception
        end if
    end if
end if
set upload = nothing
