如何同时验证三处才能进入系统？在此先谢谢各位老师了！~~
我有个表单有三项内容要同时验证才能进入系统是什么做呢？下面代码是参考出来的，但不什么改要同时验证三处~~~谢谢了！
我是刚入门的很多代码还是不够理解，可以的话做个注释~
程序代码：<!-- #include file="conn.asp" -->
<%
sql="select * from config"
set rs_config=conn.execute(sql)
biaoji=rs_config("biaoji")
%>
<%
bm=trim(request.form("bm"))
username=trim(request.form("username"))
password=trim(request.form("password"))
%>
<%if username<>"" and password<>"" then%>
<%
'根据从表单中提取出的数据，对比数据库中的数据检验用户名和密码是否合法。
set rsadm=server.createobject("adodb.recordset")
sqladm="select * from user where username='"&username&"'"
rsadm.open sqladm,conn,1,1
if not rsadm.eof then
if rsadm("password")="" then
response.write("<script>alert('用户名不对！');history.go(-1)</script>")
end if
if password=rsadm("password") then
session("bm")=rsadm("bm")
session("username")=rsadm("username")
session("password")=rsadm("password")
response.redirect "reg.asp"
'response.redirect "index.asp?user="&user&""
else
response.write("<script>alert('密码不对哦！');history.go(-1)</script>")
end if
else
end if
response.write("<script>alert('用户名不对！');history.go(-1)</script>")
rsadm.close
set rsadm=nothing
conn.close
set conn=nothing
end if%>
