<strong>用戶注冊</strong>

我自己寫的 很簡單，100%適合新人。加密了密碼，利用的是MD5
❷ 跪求簡單的php用戶注冊源碼
用$_POST[ ]的方法來獲取用戶表單里填寫的信息，然後再獲取之後用php寫查詢語句，看提交的是否為空，為空則怎樣提示，不為空就查找，查找到了就登錄成功，查不到就登錄信息錯誤。
❸ php網站登錄注冊源碼
//login.php 負責處理用戶登錄與退出動作
if(!isset($_POST['submit'])){
exit('非法訪問!');
}
$username = htmlspecialchars($_POST['username']);
$password = MD5($_POST['password']);
//包含資料庫連接文件
include('conn.php');
//檢測用戶名及密碼是否正確
$check_query = mysql_query("select uid from user where username='$username' and password='$password' limit 1");
if($result = mysql_fetch_array($check_query)){
//登錄成功
$_SESSION['username'] = $username;
$_SESSION['userid'] = $result['uid'];
echo $username,' 歡迎你！進入 <a href="my.php">用戶中心</a>
';
echo '點擊此處 <a href="login.php?action=logout">注銷</a> 登錄！
';
exit;
} else {
exit('登錄失敗！點擊此處 <a href="javascript:history.back(-1);">返回</a> 重試');
}
註：上述源碼是在TP中的登錄驗證方法，供參考！！
❹ 用PHP做登陸注冊頁面
登錄頁：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='$password'") or die("sql語句執行失敗");
//print_r($sql);
$ar=mysql_query($sql);
if($ar)
{
if($row=mysql_fetch_array($ar))
{
session_start();
if($_POST["yanzheng"])
{
if($yanzheng!=$_session[pic]||$yanzheng=="")
{
echo "驗證碼輸入有誤";
exit;
}
if($yanzheng==$_session[pic])
{
header("location:index.php");
}
}
}
else
{
echo "用戶名或密碼錯誤";
}
}
}
?>

$id=D('User')->addData($_POST);
if($id){
//注冊加積分
$this->AddScore($id);
D('Message')->sysSendMessage($id);
$data['uid']=$id;
$data['create_time']=date('Y-m-dH:i:s',time());
$data['come_here']=$_SESSION['fromUrl'];
$data['last_login']=time();
D('UserExtend')->addData($data);
//注冊就要存SESSION此處新添加，後面商量
$_SESSION['userInfo']=D('User')->getDataById($id);
$_SESSION['userInfo']['extend']=D('UserExtend')->getDataByMap(array('uid'=>$id));;
$_SESSION['userInfo']['extend']['pic']=$_SESSION['userInfo']['extend']['pic']?$_SESSION['userInfo']['extend']['pic']:"/Public/image/default.jpg";

❻ 求份php注冊登錄需要邀請碼才能注冊的源碼，要求自己能生成邀請碼，付費也可以。
把邀請碼存在資料庫，注冊的時候查詢一下這個邀請碼存在就可以注冊，不存在就不能注冊。最好加兩個欄位一個被邀請的號碼，一個自己的邀請碼
❼ php會員登錄與注冊的源代碼，及其原理。。。
登錄：判斷輸入的用戶名或密碼是否合法，是則連接資料庫，查詢輸入的用戶名是否存在，密碼是否相同，是則登錄成功！
注冊：所有的注冊信息都要判斷是否合法，是則連接資料庫，檢查用戶輸入的賬號是否已被使用，如果沒被使用，就可以把信息插入資料庫，然後提示成功、跳轉頁面；
❽ php 注冊和登陸頁面代碼+session使用問題:form1.php為注冊頁,form2.php為登陸頁,怎麼用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>
