求一个用php做的注册和登录页面能提交到mysql的,端口是3307,数据库名是bbs,
表名是user-info,注册的是register.php 登录的是login.php
求代码,用来参考学习


回复讨论(解决方案)

这种代码网上很多吧,随便一搜一大把。

其实php的登录注册,说白了就是php执行select跟insert SQL语句,然后做些相应的跳转。

我想要的是代码,能给我提供学习

骚年,百度/google一下就有了,何必在这等别人给你写呢

随便下载个开源的你就可以看到了。

 不是这缺就是哪个对方不对的,改起来麻烦,我对php还不是很熟悉,我是做java  我们部门要求掌握php的一些基础知识,所以喽

<?phpif(!in_array($_POST['type'],array('login','reg'))){	echo -1;	exit();}if($_POST['type']=='login'){	$username=addslashes($_POST['username']);	$pwd=$_POST['pwd'];	$sql="SELECT * FROM test WHERE name='$username'";//test改为user-info	$db=new DB();	if($user_exists=$db->execute_dql($sql)){		if(md5($pwd)==$user_exists[0]['pwd']){			session_start();			$_SESSION['username']=$user_exists[0]['name'];			echo 1;			exit();		}	}else{		echo -1;		exit();	}}elseif($_POST['type']=='reg'){	$username=addslashes($_POST['username']);	$pwd=md5($_POST['pwd']);	$sql_exists="SELECT * FROM test WHERE name='$username'";//test改为user-info	$db=new DB();	if($db->execute_dql($sql_exists)){//已存在该用户		echo -2;		exit();	}	$sql="INSERT INTO test(name,pwd) VALUES('$username','$pwd')";//test改为user-info	if($code=$db->execute_dml($sql)){		session_start();		$_SESSION['username']=stripslashes($username);		echo 1;		exit();	}else{		echo -1;		exit();	}}class DB{	private $conn;	private $host="localhost";//localhost:3307	private $user="root";	private $password="123456";	private $db="test";//bbs	private $res;	function __construct(){		$this->conn=mysql_connect($this->host,$this->user,$this->password);		if(!$this->conn){			die("连接数据库失败".mysql_error());		}		mysql_select_db($this->db,$this->conn);		mysql_query("SET NAMES utf8");	}	function execute_dql($sql){		$this->res=mysql_query($sql,$this->conn) or die(mysql_error());		$r=array();		while($row=mysql_fetch_assoc($this->res)){			$r[]=$row;		}		return $r;	}	function execute_dml($sql){		$b=mysql_query($sql,$this->conn) or die(mysql_error());		if(!$b){			return 0;//失败		}else{			if(mysql_affected_rows($this->conn)>0){				return 1;//成功			}else{				return 2;//没有影响到行数			}		}	}	function __destruct(){		if(!empty($this->res)){			mysql_free_result($this->res);		}		mysql_close($this->conn);	}}?>

上面发错了,前台页面,用了jquery

<html><head><meta http-equiv="content-type" content="text/html;charset=utf-8"><script language="javascript" type="text/javascript" src="jquery.min.js"></script><script type="text/javascript">$(function(){	$(':button[name=login]').click(function(){		var username=$('#l_username').val();		var pwd=$('#l_pwd').val();		if($.trim(username)=='' || $.trim(pwd)==''){			alert('用户名或密码不能为空');			return false;		}		$.ajax({			type:'post',			url:'exe.php',			data:{				username:username,				pwd:pwd,				type:'login'			},			success:function(res){				if(res==1){					window.location.reload();				}else{					alert('用户名或密码错误');				}			}		});	})	$(':button[name=reg]').click(function(){		var username=$('#r_username').val();		var pwd=$('#r_pwd').val();		var pwd1=$('#r_pwd1').val();		if($.trim(username)=='' || $.trim(pwd)=='' || $.trim(pwd1)==''){			alert('用户名或密码不能为空');			return false;		}		if($.trim(pwd)!=$.trim(pwd1)){			alert('两次输入不匹配');			return false;		}		$.ajax({			type:'post',			url:'exe.php',			data:{				username:username,				pwd:pwd,				type:'reg'			},			success:function(res){				if(res==1){					alert('注册成功');					window.location.reload();				}else if(res==-2){					alert('用户名已存在');				}else{					alert('注册失败');				}			}		});	})})</script></head><body><?phpsession_start();if(isset($_SESSION['username']) && !empty($_SESSION['username'])){	echo $_SESSION['username'].'   欢迎回来';}else{?><div>	<h3>登录</h3>	用户名:<input type="text" id="l_username"><br/>	密 码:<input type="password" id="l_pwd"><br/>	<input type="button" name="login" value="登录" ></div><hr><div>	<h3>注册</h3>	用户名:<input type="text" id="r_username"><br/>	密 码:<input type="password" id="r_pwd"><br/>	确 认:<input type="password" id="r_pwd1"><br/>	<input type="button" name="reg" value="注册"></div><?php }?></body></html>
