我把session 和cookie 放到model里不行吗？
Modelpassword.php
class Password extends Model{
function Password(){
parent::Model();
$this->load->database();
}
function ls_rand($min = NULL,$max = NULL){
static $seeded;
if(!isset($seeded)){
mt_srand((double)microtime()*1000000);
$seeded = true;
}
if(isset($min)&&isset($max)){
if($min>=$max){
return $min;
}else{
return mt_rand($min,$max);
}
}else{
return mt_rand();
}
}
//加密
function encrypt_password($plain){
$password = '';
for($i=0;$i<10;$i++){
$password.=$this->ls_rand();
}
$salt = substr(md5($password),0,2);
$password = md5($salt.$plain).':'.$salt;
return $password;
}
//解密
function check_password($get_ps,$data_ps){
$A_data_ps = explode(":",$data_ps);
//echo "<BR>data ps==>".$A_data_ps;
$A_data_ps_1 = $A_data_ps['0'];
$A_data_ps_2 = $A_data_ps['1'];
$check_ps = md5($A_data_ps_2.$get_ps).':'.$A_data_ps_2;
//echo $check_ps;
//return $check_ps;
if($check_ps==$data_ps){
return true;
}else{
return false;
}
}
//Cookie setting
function Log_set_Cookie($log_name,$password){
$log_name_len = strlen($log_name)+20050902;
$name_password = convert_uuencode($log_name.$password.":".$log_name_len);
$CA_name_password = array(
name=>'C_log',
value=>'$name_password',
expire=>'3600',
path=>'/',
);
set_cookie($CA_name_password);
//return convert_uuencode($name_password);
}
//sesssion setting
function Log_set_Session($log_name,$password){
$A_S_Log = array(
log_name =>'$log_name',
password =>'$password',
);
$this->session->set_userdata($A_S_Log);
}
//登陆验证
function login_check($login_name,$password){
$sql = "SELECT * FROM zr_admin where log_name='$login_name'";
//echo $sql;
$query = @$this->db->query($sql);
$row = @$query->row();
$data_ps = @$row->password;
$log_name = @$row->log_name;
//echo "data ps ===>".$data_ps;
if(@$this->check_password($password,$data_ps)==true){
//session
$this->Log_set_Session($log_name,$data_ps);
//Cookie
$this->Log_set_Cookie($log_name,$data_ps);
return true;
}else{
return false;
}
}
}

是不是cookie和session不能放到model里啊？ 没人会吗？ 你自己看看吧，你的语法有问题，变量要加 $ 已经解决了！！
