用户表

CREATE TABLE `sky_user` (

  `userid` int(11) unsigned NOT NULL AUTO_INCREMENT,

  `nickname` varchar(16) not null  DEFAULT '' comment '昵称',

  `username` varchar(16) NOT NULL default '' comment '用户名',

  `gender` tinyint(4) UNSIGNED  NOT NULL DEFAULT '1' COMMENT '性别',

  `user_head` varchar(255) NOT NULL DEFAULT '/static/img/head/2019.jpg' comment '头像',

  `last_time` datetime NOT NULL DEFAULT '1988-02-01 12:12:12' comment '最后登录时间',

  `salt` varchar(6) NOT NULL DEFAULT '' comment '加密串',

  `password` varchar(64) NOT NULL DEFAULT '' comment '密码',

  `reg_time` datetime NOT NULL DEFAULT '2016-05-11 14:53:01' COMMENT '注册时间',

  PRIMARY KEY (`userid`),

 key(username),

 key(nickname)

) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 comment '用户表';

注册 register.ctrl.php

我们需要验证

1.用户名、昵称是否为空 是否已存在

2.两次输入密码是否一致

<?php
class registerControl extends skymvc{
	
	public function __construct(){
		parent::__construct();
	}
	
	public function onDefault(){
		
		$this->smarty->display("register/index.html");
	}
	
	public function onRegSave(){
		$password=post('password','h');
		$password2=post('password2','h');
		if($password!=$password2 or empty($password)){
				$this->goall("两次输入的密码不一致",1);		
		}
		$data['username']=post('username','h');
		if(empty($data['username']) ){
			$this->goAll("用户名不能为空",1);
		}
		
		$data['nickname']=post('nickname','h');
		if(empty($data['nickname']) ){
			$this->goAll("昵称不能为空",1);
		}
		$data['gender']=post('gender','i');
		if(M("user")->selectRow(array("where"=>"username='".$data['username']."' "))){
			$this->goall("用户名已经存在",1);
		}
		if(M("user")->selectRow(array("where"=>"nickname='".$data['nickname']."' "))){
			$this->goall("昵称已经存在",1);
		}
		$data['salt']=rand(1000,9999);
		$data['password']=umd5($password.$data['salt']);
		$userid=M("user")->insert($data);
		$this->goAll("注册成功，请登录",0,$user,"/index.php?m=login");
	}
	
}

?>

登录 login.ctrl.php

登录

查询用户名是否有

检查密码是否一致

注销

<?php
class loginControl extends skymvc{
	
	public function __construct(){
		parent::__construct();
	}
	
	public function onInit(){
		
	}
	
	public function onDefault(){
		$this->smarty->assign(array(
			"backurl"=>$_SERVER['HTTP_REFERER']
		));
		$this->smarty->display("login/index.html");
	}
	
	public function onloginSave(){
		$username=post('username','h');
		$password=post('password','h');
		$user=M("user")->selectRow("username='".$username."'");
		if(!$user){
			$this->goAll('账号不存在',1,"",$_SERVER['HTTP_REFERER']);
		}
		if($user['password']!=umd5($password.$user['salt'])){
			$this->goall("密码出错了",1,"",$_SERVER['HTTP_REFERER']);
		}
	 
		$this->set_session('ssuser',$user);
		$authcode=jiami($user['userid']."|".umd5($user['password']));
		if(ISWAP or post('autologin')){ 
			 
			$this->set_cookie("authcode",$authcode,3600);
		}
		$redata=array(
			"authcode"=>$authcode
		);
		$this->goAll("登录成功",0,$redata,get_post('backurl'));
		
	}
	
	public function onLogout(){
		 
		 $this->del_session("ssuser");
		 $this->set_cookie("authcode","",time()-10);	
		$this->goall("注销成功",0,0,"/index.php");
	}
	
	
	
	
}
