网站登录代码怎么写

yonghu=request.Form("yonghu")

mima= request.Form("mima")

SqlStr = "select * from [biaoge] Where yonghu="yonghu" and mima=" mima " order by id desc"

Set Rs = Server.CreateObject("adodb.recordset")

Rs.Open SqlStr, Conn, 1, 1

IF Not(Rs.bof and Rs.EOF) Then

response.write("登陆成功")

Else

response.write("登陆失败")

End If

Rs.close

Set Rs = nothing

求写个比较简单的php登陆页面代码

index.php 录入页代码form id="form1" name="form1" method="post" action="login.php"

table width="400" border="0" align="center" cellpadding="1" cellspacing="1" class="tableborder"

tr

tddiv align="right"用户名：/div/td

td width="244"

input type="text" name="User_name" id="User_name" / /td

/tr

tr

tddiv align="right"密　码：/div/td

tdinput type="Password" name="User_Password" id="User_Password" //td

/tr

tr

td

div align="right"

input type="submit" name="button" id="button" value="提交" /

/div/td

tdinput type="reset" name="button2" id="button2" value="重置" //td

/tr

/table

/form login.php提交页代码?

error_reporting(0);

$mysql_servername = "127.0.0.1";

$mysql_username = "root";

$mysql_password ="123456";

$mysql_database ="first";

mysql_connect($mysql_servername , $mysql_username , $mysql_password);

mysql_select_db($mysql_database);

$U_name=$_POST['user_name'];

$U_passowrd=$_POST['user_password'];

if ($U_name $U_passowrd){

$sql = "SELECT * FROM admin WHERE U_name = '$U_name' and U_password='$U_passowrd'";

$res = mysql_query($sql);

$rows=mysql_num_rows($res);

if($rows){

header("location='c.php'");

exit;

}

echo "script language=javascriptalert('用户名密码错误');history.back();/script";

}else {

echo "script language=javascriptalert('用户名密码不能为空');history.back();/script";

}

网页会员的登陆代码

login.asp页代码如下 =============================================== form name=login action="loginOK.asp" input type="text" name="ID" input type="password" name="PASS" input type="submit" name="submit" value="登录" /form loginOK.asp页代码如下 =============================================== ID = request("ID") PASS =request("PASS") if ID="" then response.write("scriptalert('用户名不能为空');history.go(-1);/script") response.end elseif PASS="" then response.write("scriptalert('密码不能为空);history.go(-1);/script") response.end end if sql = "select * from user where ID='"ID"' and pass='"PASS"'" set rs = conn.execute(sql) if not rs.eof then response.write("scriptalert('登陆成功！！');location='/index.asp';/script") else response.write("scriptalert('登陆失败！！请检查用户名和密码是否正确');history.go(-1);/script") end if set rs = nothing ************************************************* 这里的 user 是你的数据库里面保存用户信息的数据表，楼主改称自己的表名就可以了 另外，搂住得数据库是什么的?? access 还是 sql 的？？ 如果是access的 %set conn=server.CreateObject("ADODB.connection") conn.ConnectionString="driver={Microsoft Access Driver (*.mdb)};DBQ="server.MapPath("数据库文件的路径") ";uid=;PWD=;" conn.open% 如果是sql server的 % '---------------------------------------------------------- strSQLServerName = "127.0.0.1" '数据库服务器的ip strSQLDBUserName = "sa" '用户名（一般不用变） strSQLDBPassword = "12345456"'连接数据库的密码 strSQLDBName = "WebDB" '数据库名 '---------------------------------------------------------- Set conn = Server.CreateObject("ADODB.Connection") connstr = "Provider=SQLOLEDB.1;Persist Security Info=False;Server=" strSQLServerName ";User ID=" strSQLDBUserName ";Password=" strSQLDBPassword ";Database=" strSQLDBName ";" conn.Open connstr %

用ASP制作登陆页面的代码

时间关系，没给你写 所以就复制了一段 可到我论坛看看

代码如下：

1.connection.asp里的代码是:

%

set conn=server.createobject("adodb.connection")

conn.open "provider=microsoft.jet.oledb.4.0;data source="server.MapPath("student.mdb")

%

2.yanzheng.asp里的代码是:

!--#include file="connection.asp"--

%

dim zhanghao,mima

zhanghao=request("zhanghao")

mima=request("mima")

if zhanghao="" then

%

script language=javascript

alert("帐号为空");

location.href="denglu.asp"

/script

% end if %

% if mima="" then

%

script language=javascript

alert("密码为空");

location.href="denglu.asp"

/script

% end if %

%set rs=server.createobject("adodb.recordset")

rs.open "select * from student where zhanghao='"zhanghao"'",conn,1,3

if not rs.eof then

if mima=rs("mima") then

session("zhanghao")=zhanghao

Response.write("scriptlocation.href('index.asp')/script" )

else

response.write ("scriptalert('用户密码错误');location.href('denglu.asp')/script")

end if

end if

if rs.eof then

response.write ("scriptalert('用户帐号错误');location.href('denglu.asp')/script")

end if

set rs=nothing

rs.close

%

二、

conn.asp

%

Set conn=Server.CreateObject("ADODB.Connection")

connstr="DBQ="+server.mappath("haha.mdb")+";DefaultDir=;DRIVER={Microsoft Access Driver (*.mdb)}"

conn.Open connstr

%

index.asp

%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%

!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" ""

html

head

meta http-equiv="Content-Type" content="text/html; charset=gb2312"

title无标题文档/title

/head

body

form name="form1" method="post" action="login.asp"

table width="50%" height="108" border="0" cellpadding="0" cellspacing="0"

tr

td用户名：/td

tdinput name="us" type="text" id="us"/td

/tr

tr

td密码：/td

tdinput name="pa" type="password" id="pa" value=""/td

/tr

tr

td /td

tdinput type="submit" name="Submit" value="提交"/td

/tr

/table

/form

/body

/html

login.asp

!--#include file="conn.asp"--

%

us=replace(request.form("us"),"'","’")

pa=replace(request.form("pa"),"'","’")

%

%

set rs=server.createobject("adodb.recordset")

sql="select * from haha where us='"us"' and pa='"pa"'"

rs.open sql,conn,1,1

%

%

if rs.eof or rs.bof then

response.write"密码错误~"

else

response.redirect"main.asp"

end if

%

三、

连接数据库(conn.asp)

%

dim db,conn,connstr

db="@data.mdb"

set Conn = server.CreateObject("ADODB.Connection")

connstr="provider=microsoft.jet.oledb.4.0;data source=" server.MapPath("../data/"db"")

conn.Open connstr

%

登录页面（login.asp）

% @language=vbscript %

!--#include file="conn.asp"--

%

On Error Resume Next

dim uid

dim pwd

uid=trim(request.Form("uid")) '获得用户名

pwd=trim(request.form("pwd")) '获得密码

dim rs

set rs=server.createobject("adodb.recordset")

if uid"" then

dim sqlstr

sqlstr="select uid,pwd from admin where uid='"replace(uid,"'","''")"' and pwd='"replace(pwd,"'","''")"'"

rs.open sqlstr,conn,3,1

if not rs.eof then

session("uid")=uid

response.redirect "login_ok.asp" '重定位url

else

response.redirect "error.htm"

end if

else

response.redirect "error.htm"

end if
