无组件上传源码
⑴ ASP无组件批量上传图片
使用风声无组件上传类
<%
Set myRequest=new UpLoadClass
myRequest.FileType ="gif/jpg"'"gif/jpg"
myRequest.Savepath = "pic/"
myrequest.open
sql = "select * from tab"
set rs = server.createobject("adodb.recordset")
rs.open sql,conn,1,3
rs.addNew
rs("title") = myRequest.Form("title")
rs("file1") = myRequest.Form("file1")
rs("file2") = myRequest.Form("file2")
rs.update
set rs = nothing
%>
1.文件自动上传到pic目录自按日期时间生成不重复的文件名
2.上传的文件的文件名自动生成并可这样取出
myRequest.Form("file1")
3.text框的数据这样取
myRequest.Form("title")
4.这个类的代码可在这里
