配置 config.php

‘DB_HOST’ =>'localhost', 

‘DB_USER’ => 'root',//用户名

‘DB_PWD’ => '', //密码

‘DB_NAME’ =>'',  //名称

‘DB_PREFIX’ =>  //前缀

$db = M('user');

$user = $db->where(array('username' => I('username')))->find();

p($user)

if(!$user || $user['password'] == I('password','','MD5')){

$htis->error('账户或密码错误');

}

更新

$data = array(

'id'=>$user['id'],

'logintime'=>time(),

'loginip' =>get_client_ip()

);

$db->save($data);

写进SESSION

session('uid',$user['id']);

session('username',$user['username']);

session('logintime',date('Y-m-d H:i:s'),$user['logintime']));

session('loginip',$user['loginip']);
