asp上傳圖片的代碼詳細的,最好是有步驟的

使用風聲無組件上傳類

<%

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.文件自動上傳到pic目錄自按日期時間生成不重復的文件名

2.上傳的文件的文件名自動生成並可這樣取出

myRequest.Form("file1")

3.text框的數據這樣取

myRequest.Form("title")

4.這個類的代碼可在這裏
