<!DOCTYPEhtml>2. 求一用php写的注册和登录页面代码
reg.php文件
<?php
header("Content-type:text/html;charset=utf-8");
if($_POST){
$dsn = 'mysql:dbname=1104javab;host=127.0.0.1';
$user = 'root';
$password = '';
try{
$pdo = new pdo($dsn,$user,$password,array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'')
);
}catch(Exception $e){
echo '错误'.$e->getmessage();
}
$name = $_POST['name'];
$pwd = md5($_POST['pwd']);
$sql = "insert into 表 (username,password) values ('$name','$pwd')";
$exec = $pdo->query($sql);
if($exec){
echo "<script>alert('成功');location.href='reg.html'</script>";
}else{
echo "<script>alert('失败');location.href='reg.html'</script>";
}
}
?>
reg.html文件
<form action='reg.php' method='post'>
用户名:<input type='text' name='name'>
密码:<input type='password' name='pwd'>
<input type='submit' value='submit'>
</form>
login.html文件
<form action='reg.php' method='post'>
用户名:<input type='text' name='name'>
密码:<input type='password' name='pwd'>
<input type='submit' value='submit'>
</form>
login.php文件
header("Content-type:text/html;charset=utf-8");
if($_POST){
$dsn = 'mysql:dbname=1104javab;host=127.0.0.1';
$user = 'root';
$password = '';
try{
$pdo = new pdo($dsn,$user,$password,array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'')
);
}catch(Exception $e){
echo '错误'.$e->getmessage();
}
$name = $_POST['name'];
$pwd = $_POST['pwd'];
$sql = "select user_id from 表名 where username='$name' and password='$pwd'";
$stmt = $pdo->query($sql);
$info = $stmt->fetch(PDO::FETCH_ASSOC);
if($info){
echo "登录成功";
}else{
echo "登录失败";
}
}
大概这样
3. 用户登陆和注册代码怎么用C#写,求解
先设计一张后台数据表Login(如字段：username,pwd)
在登录界面放置两个textbox，一个版btn
登录时在一个框内输权入用户名，一个输入密码，点击按钮，在按钮点击事件中执行SQL查询语句：selecd
*from
Login
where
username='textbox1'
and
pwd='textbox2'
注册时用SQL插入语句：insert
into
Login
(username,pwd)
values('textbox1'
,'textbox2')
4. c#用代码实现注册登录代码
/*
*
输入用户名的文本框是txt_UserName;
*
输入真实姓名的文本框时txt_UserRegName
*
输入密码的文本框是txt_Password
*
注册提交按钮是btn_Register
*/
//注册提交按钮点击事件
private
void
btn_Register_Click(object
sender,
EventArgs
e)
{
using(SqlConnection
connection
=
new
SqlConnection("[<数据库连接字符串>]"))//初始化到数据库的连接
{
try
{
connection.Open();//打开此数据库连接
SqlCommand
sqlText
=
new
SqlCommand("insert
into
[<用户名表>]
values
(@nm,@rn,@pw)",
connection);//建立数据库命令对象
//添加数据库命令参数
sqlText.Parameters[0].Value
=
txt_UserName.Text;
sqlText.Parameters[1].Value
=
txt_UserRegName.Text;
sqlText.Parameters[2].Value
=
txt_Password.Text;
if
(sqlText.ExecuteNonQuery())
MessageBox.Show(this,
"注册失败",
"错误",
MessageBoxButtons.OK,
MessageBoxIcon.Error,
MessageBoxDefaultButton.Button1);
else
MessageBox.Show(this,
"恭喜您,注册成功!",
"成功",
MessageBoxButtons.OK,
MessageBoxIcon.Information,
MessageBoxDefaultButton.Button1);
}
catch
(SqlException
exception)
{
MessageBox.Show(this,
"注册失败:\n"
+
exception.Message,
"错误",
MessageBoxButtons.OK,
MessageBoxIcon.Error,
MessageBoxDefaultButton.Button1);
}
finally
{
connection.Close();
}
}
}
[<>]的不是代码,是要根据你自己情况写的
同样,SQL语句的参数也是.
5. html登陆注册代码有会的写一下！
<form
method="post"
action="login.asp">
<table>
<tr>
<td>用户名来</td><td><input
type="text"
name="user_ID"/></td>
</tr>
<tr>
<td>密码</td><td><input
type="password"
name="user_PWD"/></td>
</tr>
</table>
<input
type="submit"
value="提交"/>
</form>
表单源的内容提交到后台程序，这个提交到login.asp了

在ACCESS中建一个表，然后在这个表中建立字段名称

字段名称 数据类型
id 自动编号

qq 文本
mail 文本
personalinfo 文本
ntime 文本
7. 注册/登陆页面HTML代码该怎么写
以下为个人原创教学例子，任何人引用需注明出自网络知道用户am7972,楼主可供参考
该例子涵盖了文本框、密码框、下拉菜单、单选框、复选框及文本区的使用
同时在数据的使用方面涵盖了文本型、数值型、日期型、布尔型的使用
也涵盖了在会员信息入数据库前，进行严格的数据检查
不足处，JS验证还不是太完善，不过有服务端认证足够了
<title>会员注册</title>
<script type="text/javascript">
<!--function CheckForm()
{
if(document.userinfo.username.value == "")
{ alert("请输入姓名,姓名不能为空！");
document.userinfo.username.focus();
return false;
}
if(document.userinfo.username.value.length > 10)
{
alert("输入的姓名长度最多为10个字符！");
document.userinfo.username.focus();
return false;
}
}

====登陆的HTML代码可相信楼主参照会员注册代码应该没问题了====
8. 如何用eclipse写登录注册页面的代码
java写的用户登录实例，实际页面展示使用的jsp，那么下面是的登录页面代码：
1、login.jsp代码
<%
string name = request.getparameter("username");
string pwd = request.getparameter("password");
//out.println(name+pwd);
string sql ="select * from info where username='"+name+"' and password='"+pwd+"'";
//out.println(sql);
statement stm= null;
resultset rs =null;
try
{
stm = conn.createstatement();
rs = stm.executequery(sql);
if(rs.next())
{
session.setattribute("username",name);
response.sendredirect("index.html");
}
else
{
response.sendredirect("index1.html");
}
}
catch(sqlexception e)
{
e.printstacktrace();
}
%>
<!--登录的表单-->
<form name="form1" method="post" action="login.jsp">
<p>
<label for="username"></label> 用户名
<input type="text" name="username" id="username">
</p>
<p>
<label for="passwrod"></label> 密码
<input type="text" name="passwrod" id="passwrod">
</p>
<p>
<input type="submit" name="button" id="button" value="提交">
</p>
</form>
2、用户信息表，存放用户名和密码：
user_info 表
create table if not exists `test` (
`id` int(8) not null auto_increment,
`username` char(150) default null,
`password` varchar(32),
`times` int(4) not null,
primary key (`id`)
) engine=myisam default charset=utf8 auto_increment=1 ;
9. 求一个HTML登陆注册代码！
用户名
密码
表单的内容提交到后台程序，这个提交到login.asp了
