<strong>用户注册</strong>
<form action="reg.php" method="post">
用户名称：<input type="text" name="user"><br>
您的密码：<input type="password" name="pass"><br>
确定密码：<input type="password" name="pass2"><br>

<?php
include ('conn.php'); //这里是您配置的数据库
if($_POST[submit]){
//判断用户名不低于字数
$struser=strlen($_POST[user]);
if($struser <= 4){
echo "<script language=javascript>alert('注册请输入5位数以上');history.go(-1);</script>";
exit;
}
//判断用户是否存在
$users=$_POST[user];
$result=mysql_query("select * from manage where user='$users'");
$row=mysql_fetch_array($result);
if($_POST[user]==$row[user]){
echo "<script language=javascript>alert('啊！这个名字有人注册啦！');history.go(-1);</script>";
exit;
}
//判断用户密码两次输入正确
if($_POST[pass]!=$_POST[pass2]){
echo "<script language=javascript>alert('亲，别耍我啦，两次密码怎么能输入不一样呢？');history.go(-1);</script>";
exit;
}
$_POST[pass]=md5($_POST[pass]);
$sql=mysql_query("insert into manage(id,user,pass)
VALUES('','$_POST[user]','$_POST[pass]')
");
if($sql){
echo "<script language=javascript>alert('亲,注册成功！');history.go(-1);</script>";
}
else {
echo "<script language=javascript>alert('对不起，亲！注册失败咯！');history.go(-1);</script>";
}
exit;
}
mysql_close($con)
?>
我自己写的 很简单，100%适合新人。加密了密码，利用的是MD5
❷ 跪求简单的php用户注册源码
用$_POST[ ]的方法来获取用户表单里填写的信息，然后再获取之后用php写查询语句，看提交的是否为空，为空则怎样提示，不为空就查找，查找到了就登录成功，查不到就登录信息错误。
❸ php网站登录注册源码
//login.php 负责处理用户登录与退出动作
if(!isset($_POST['submit'])){
exit('非法访问!');
}
$username = htmlspecialchars($_POST['username']);
$password = MD5($_POST['password']);
//包含数据库连接文件
include('conn.php');
//检测用户名及密码是否正确
$check_query = mysql_query("select uid from user where username='$username' and password='$password' limit 1");
if($result = mysql_fetch_array($check_query)){
//登录成功
$_SESSION['username'] = $username;
$_SESSION['userid'] = $result['uid'];
echo $username,' 欢迎你！进入 <a href="my.php">用户中心</a>
';
echo '点击此处 <a href="login.php?action=logout">注销</a> 登录！
';
exit;
} else {
exit('登录失败！点击此处 <a href="javascript:history.back(-1);">返回</a> 重试');
}
注：上述源码是在TP中的登录验证方法，供参考！！
❹ 用PHP做登陆注册页面
登录页：login.php
<?php
include("conn.php");
$username=$_POST['name'];
$password=$_POST['password'];
$yanzheng=$_POST['yanzheng'];
if(isset($_POST['submit']))
{
$sql=("select username,password from member where username='$username' and password='$password'") or die("sql语句执行失败");
//print_r($sql);
$ar=mysql_query($sql);
if($ar)
{
if($row=mysql_fetch_array($ar))
{
session_start();
if($_POST["yanzheng"])
{
if($yanzheng!=$_session[pic]||$yanzheng=="")
{
echo "验证码输入有误";
exit;
}
if($yanzheng==$_session[pic])
{
header("location:index.php");
}
}
}
else
{
echo "用户名或密码错误";
}
}
}
?>
<form action="login.php" method="post">

注册页：register.php
<?php
include("conn.php");
if(isset($_POST['submit'])&&$_POST['submit']) {
if($_POST['username']=='')
{

exit();
}
if($_POST['password']=='')
{
echo "密码不能为空";
exit();
}
if($_POST['realpass']!=$_POST['password'])
{
echo "两次密码输入不一致";
exit();
}
$sql="insert into member(username,real_name,password,email,headimg) values('$_POST[username]','$_POST[username]','$_POST[password]','$_POST[email]','')";
$ar=mysql_query($sql);

❻ 求份php注册登录需要邀请码才能注册的源码，要求自己能生成邀请码，付费也可以。
把邀请码存在数据库，注册的时候查询一下这个邀请码存在就可以注册，不存在就不能注册。最好加两个字段一个被邀请的号码，一个自己的邀请码
❼ php会员登录与注册的源代码，及其原理。。。
登录：判断输入的用户名或密码是否合法，是则连接数据库，查询输入的用户名是否存在，密码是否相同，是则登录成功！
注册：所有的注册信息都要判断是否合法，是则连接数据库，检查用户输入的账号是否已被使用，如果没被使用，就可以把信息插入数据库，然后提示成功、跳转页面；
❽ php 注册和登陆页面代码+session使用问题:form1.php为注册页,form2.php为登陆页,怎么用S_SESSION[]
<html><body>
<?php
session_start();
$_SESSION["user"] = $_POST["user1"];
echo $_SESSION["user"] ;
?>
<form name="form2" type="post" action="new111.php">
<table>
<td><input name="user2" type="text"></td>
<td><input name="submit2" type="submit" onClick="return mycheck();" value="提交"></td>
</form>
<script language="javascript">
function mycheck(){
if(form2.submit2.value == "提交"){
if(form2.user2.value == "<?php echo $_SESSION["user1"];?>"){
alert("right!");
}else{
alert("not right!");
}
}
}
</script>
</body>
</html>
