之前曾在BLOG发过一篇无组件上传的文件采用例子：
http://www.cnbruce.com/blog/showlog.asp?cat_id=26&log_id=471
简单的应用到化境官方站点下载压缩文件，其中里面有例题：
http://www.5xsoft.com/Down.aspx?id=2
不过我这里是重新编辑的无组件上传，增添了如下内容：
1，支持图片、音频、视频、压缩等各类型文件的上传（可自定义限制的格式文件）
2，对不同类型文件的文件夹归类（按照文件类型建立文件夹，并按“年-月”建立子文件夹）
3，上传的文件名不再采用流水号（这样对搜索不好），当然也加了随机数
4，还有功能程式的说明，具体看文件内容
声明：既然是上传，一般是需要相关上传组件的支持的，而无组件上传则是由网络上盛传的稻香老农的无组件上传类，目前版本为V2.0，该文件内容如下，拷贝代码，保存为 upload.inc

接着，需要一个正常的后台信息录入平台，该平台页面是通过信息内容的输入，并提供“浏览”表单元素以提供本地文件的上传，该文件内容如下，拷贝代码，保存为index.asp
<form name="cn_bruce" method="POST" action="">
<textarea cols="100" name="cn_content" rows="18" width="100%"></textarea><br>
</form>
<iframe border="0" frameBorder="0" noResize scrolling="no" width="100%" src="upload.asp"></iframe>
其中，index.asp中的“浏览”表单元素的出现是在浮动框架内的upload.asp，用浮动框架是防止文件上传的同时与index.asp的信息干扰，该文件内容如下，拷贝代码，保存为upload.asp
<meta http-equiv="content-type" content="text/html;charset=gb2312">
<form name="form" method="post" action="upfile.asp" enctype="multipart/form-data">
<input type="hidden" name="upfilefolder" value="uploadfile">
<input type="hidden" name="act" value="upload">
<input type="file" name="file11" size=40>
<input type="file" name="file12" size=40>
<input type="file" name="file13" size=40>
<input type="submit" name="Submit" value="上传">
</form>
最后，最重要的文件就是如何将upload.asp选择的本地的文件传递到服务器上定义的文件夹中，action="upfile.asp"，该文件内容如下，拷贝代码，保存为upfile.asp
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<!--#include file="upload.inc"-->
<html>
<head>
<title>文件上传</title>
<meta http-equiv="content-type" content="text/html;charset=gb2312">

response.end
End If
f_type= replace(fileExt,".","")
f_name= year(now)&"-"&month(now)
If upf.FolderExists(Server.MapPath(f_folder&"/"&f_type&"/"&f_name))=False Then

End If
End If
f_ftn=f_folder&"/"&f_type&"/"&f_name
Set upf=Nothing
'********************************保存上传文件至文件夹*****************************************
randomize
ranNum=int(90000*rnd)+10000
filename=f_ftn&"/"&day(now)&"-"&ranNum&"-"&file.filename
if file.filesize>filesizemin and file.filesize<filesizemax then
file.SaveAs Server.mappath(filename) '保存文件

else

end if
iCount=iCount+1
end if
set file=nothing
end if
next
set upload=nothing '删除此对象
response.write (iCount&" 个文件上传成功! <a href=# onclick=history.go(-1)>继续上传</a>")
%>
</body>
</html>
注意：
1.需要服务器支持FSO，否则文件夹建立不了；
2.在文件上传后最终在index.asp的文本区域中显示什么内容，由您的编辑器类型决定。比如支持UBB，则使用UBB标签，支持HTML标签，则将upfile.asp中parent.cn_bruce.cn_content.value+= 后的内容修改。 |
