asp无限分类的问题。高手请指点
新手刚学asp不久。能写一般的网站程序。后来需要做无限分类的，就是商城。不会做。还有划分管理员等级。怎么划分。有没有高手指点一下，并给出相应的代码，并说明。小生终生感激。...
新手刚学asp不久。能写一般的网站程序。后来需要做无限分类的，就是商城。不会做。还有划分管理员等级。怎么划分。
有没有高手指点一下，并给出相应的代码，并说明。小生终生感激。混饭吃太难了，求高手指点迷经!
把所有分都给你，只有这么点了。 展开

无限级分类的主要内容：
建一个栏目表，如
栏目ID，栏目名称，父栏目ID，父栏目名称，栏目深度，栏目管理员
用递归可以得出每一级栏目的名称及其父栏目名称。代码如下：
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<%'if session("login") <> "yes" then response.Redirect "login.asp"%>
<!--#include file="conn.asp"-->
<%
sub popup(str,url)
response.write "<script language='javascript'>" & chr(13)
response.write "alert('"&str&"！');" & Chr(13)
response.write "window.document.location.href='"&url&"';"&Chr(13)
response.write "</script>" & Chr(13)
response.End()
end sub
%>
