化境ASP无组件上传类 - upload_5xsoft 使用手册 2.0
what's new
1.使用了网友“梁无惧” 提供的高效的处理方式，上传速度可提高一倍以上,可上传更大的文件。
2.添加了form 方法和file方法，把原来的 form 集和 file改为 objForm 和 objFile,避免了若上传时没有数据会出错的Bug。
3.对多选框的优化，上传同名的多选框时，会自动用 ", " 连接起来。
4.对于表单名，不再区分大小写,使用ASP使用者更习惯。
关于 upload_5xsoft
一直以来,由于FileSystemObject的局限,所以ASP最大的难题就是文件上传,大多解决法就是安装
第三方上传组件。可第三方组件有很多问题,有的组件要注册,有的组件要在表单中加上他的版权信息。
还有的就是组件的兼容问题。
在网上也流传了很多无组件上传的代码,但都是只能上传文本文件，或是只能将文件上传到数据库中。
我这段时间在研究ASP,发现可以不用第三方组件上传任意类型的文件。就写了这个类,给大家一
个方便,整个类放在一个文件中: upload_5xsoft.inc 在 Example 目录下还有一个完整的多文件上传示
例程序,可以直接使用。
申明:源代码是完全开放的,可能随意传播,但请保留其完整性,未经作者同意,不得用于商业。
运行平台与注意事项
a)可直接运行于 Windows2000+IIS 5
NT4 或是 Win98+PWS, 要安装ADO2.6 下载地址：http://www.microsoft.com/data/:
<!--#include FILE="upload_5xsoft.inc"--> 就行了
b) 在使用文件上传时, 表单 form 要加上 enctype="multipart/form-data" 即:
<form name="form1" method="post" action="" enctype="multipart/form-data">
<input type="text" value="abc" name="text1">
<input type=file name="file">
<input type=submit name="submit" value="提交">
</form>
upload_5xsoft的对象
如定义一个上传对象
<!--#include FILE="upload_5xsoft.inc"-->
<%
set upload=new upload_5xsoft 'upload就是一个对象
%>
upload_5xsoft 对象成员
File 方法，得到文件对象,例如：set file=upload.file("file1")
文件对象成员下面有说明
objFile 文件对象集,(是个dictionary对象)
文件对象成员:
Count 属性,文件表单的个数
FileName 属性,上传文件的名字
FileSize 属性,上传文件的大小(为0是表示没有文件)
FilePath 属性,上传前文件所在的路径
FormName 属性,文件表单的名字
SaveAs 方法,储存上传后文件,有一个参数,路径要为真实路径如:
例子: set file=upload.file("file1") 'file1为表单名
response.write "<br>文件名:"&file.FileName
response.write "<br>文件大小:"&file.FileSize
response.write "<br>文件路径:"&file.FilePath
file.saveAs Server.mappath("/1.jpg")
set file=nothing
Form 方法，获得表单数据,如 Response.Write upload.Form("abc")
objForm 表单数据集,(是个dictionary对象)用来代替 Request.Form
count 属性,表单数
exists 方法,检查是否有指定的表单名
更多的用法可看 vbscript 的dictionary对象帮助
例子:
'得到text1表单的数据,uplaod就是一开始创建的对象
sText=upload.form("text1")
Version 属性,upload_5xsoft类的版本号,如:
response.write upload.Version
使用示例
1.上传一个jpg文件的示例:
文件1: upload.htm
<html><title>example</title>
<body>
<form name="form1" method="post" action="upload.asp" enctype="multipart/form-data">
<input type=file name="file1">
<input type=submit name="submit" value="提交">
</form>
</body>
</html>
文件2: upload.asp
<html><title>example</title>
<body>
<!--#include FILE="upload_5xsoft.inc"-->
<%
set upload=new upload_5xsoft
set file=upload.file("file1")
response.write upload.form("submit")&"<br>"
if file.fileSize>0 then
file.saveAs Server.mappath("temp.jpg")
response.write "<br>上传文件:"&file.FileName&" => temp.jpg OK!"
response.write "<br>文件大小:"&file.FileSize
end if
set file=nothing
set upload=nothing
%></body>
</html>
2.列表出有文件表单(多文件上传)
<html><title>example</title>
<body>
<!--#include FILE="upload_5xsoft.inc"-->
<%
set upload=new upload_5xsoft
''列出所有form数据
for each formName in upload.objForm
response.write formName&"="&upload.objForm(formName)&"<br>"
next
''列出所有文件
for each formName in upload.objFile
set file=upload.objFile(formName)
if file.FileSize>0 then
file.SaveAs Server.mappath(file.FileName)
response.write file.FilePath&file.FileName&" ("&file.FileSize&") => "
response.write file.FileName&" 成功!<br>"
end if
set file=nothing
next
set upload=nothing

首先，图片在页面中能查找选择。设计表单页面index.asp和上传选择页upload.asp，upload.asp在index.asp中以iframe包含。
其次，所选图片应能上传到某文件夹。建立一文件夹uploadimg
最后，传上去的图片应如何引用？很显然，采用UBB立即显示。upload.asp的指向对象upfile.asp具有写入UBB标签的功能。
无组件上传调试文件夹
-- index.asp
-- upload.asp
-- upfile.asp
-- uploadimg文件夹
图片上传采用稻香老农的无组件上传。所以upload.inc文件必不可少。

</form>
<iframe border="0" frameBorder="0" noResize scrolling="no" width="100%" src="upload.asp"></iframe>
3，上传选择页upload.asp 注意： enctype="multipart/form-data"
<form name="form" method="post" action="upfile.asp" enctype="multipart/form-data">
<input type="hidden" name="filepath" value="uploadimg">
<input type="hidden" name="act" value="upload">
<input type="file" name="file1" size=40>
<input type="submit" class=button name="Submit" value="上传图片" οnclick="parent.document.forms[0].Submit.disabled=true">类型：gif,jpg，限制：100K
</form>
4，最后一 个文件 upfile.asp 主要作用：生成图片名，并将图片上传，同样也要将UBB标签写入index.asp中的textarea中。
