cookie未设置无法正常工作

问题描述：

I am using remember option in my login page.I think I am doing right but when in logout I just amn't able to unset the cookie variable.I am using CI but for cookie I am using native cookie.What am I doint wrong?My code: in login controller:

function index(){
if(isset($_COOKIE['remember_me'])){
  redirect('index');
}elseif($this->input->post()){
  $username = $this->input->post('username');
  $password = $this->input->post('password');
  $remember = $this->input->post('remember');
  if($remember){
      $time = time()+60*60*24*365;
      setcookie('remember_me', $username , $time);
  }
  $this->session->set_userdata('user_name', $user_name);
  $this->session->set_userdata('full_name', $full_name);
  $this->session->set_userdata('server', $server->exchange_server);
  redirect('index');
}else{
  $this->load->view('login');
}
}
function logout(){
 $this->session->unset_userdata('user_name');
 $this->session->unset_userdata('full_name');
 $this->session->unset_userdata('server');
 $data['login'] = 'Logout Successfully.';
 $data['class'] = 'success';
 $this->session->set_flashdata($data);
/* To unset cookie i tried following different approach but to no avail*/
setcookie('remember_me');
setcookie('remember_me', '', $time()-60*60*24*365);
setcookie('remember_me', false);
unset($_COOKIE['remember_me']);
 redirect('login');
}

but to no avail. I just can't unset cookie and when user who has checked remember me option trys to logout it's not happening. Any help/suggestion is welcome.Thanks

I don't know what is the problem but I used jquery plugin for cookie delete {https://github.com/carhartl/jquery-cookie}. I included jquery.cookie.js and then on logout click I deleted the cookie set as $.removeCookie('remember_me')

我在登录页面中使用了记住选项。我想我做得对，但在退出时我只是' 能够取消设置cookie变量。我正在使用CI但是对于cookie我使用原生cookie。我做错了什么？我的代码： in登录控制器： p>

  function  index（）{
if（isset（$ _ COOKIE ['remember_me']））{
 redirect（'index'）; 
} elseif（$ this-＆gt; input-＆gt; post（））{
 $  username = $ this-＆gt; input-＆gt; post（'username'）; 
 $ password = $ this-＆gt; input-＆gt; post（'password'）; 
 $ remember = $ this-＆gt; input  - ＆gt; post（'remember'）; 
 if（$ remember）{
 $ time = time（）+ 60 * 60 * 24 * 365; 
 setcookie（'remember_me'，$ username，$ time）;  
} 
 $ this-＆gt; session-＆gt; set_userdata（'user_name'，$ user_name）; 
 $ this-＆gt; session-＆gt; set_userdata（'full_name'，$ full_name）; 
 $ this-  ＆gt; session-＆gt; set_userdata（'server'，$ server-＆gt; exchange_server）; 
 redirect（'index'）; 
} else {
 $ this-＆gt; load-＆gt; view（'login'  ）; 
} 
} 
 
函数logout（）{
 $ thi  s-＆gt; session-＆gt; unset_userdata（'user_name'）; 
 $ this-＆gt; session-＆gt; unset_userdata（'full_name'）; 
 $ this-＆gt; session-＆gt; unset_userdata（'server'）  ; 
 $ data ['login'] ='注销成功。'; 
 $ data ['class'] ='成功'; 
 $ this-＆gt; session-＆gt; set_flashdata（$ data）; 
  / *要取消设置cookie，我尝试了不同的方法，但没有用* / 
setcookie（'remember_me'）; 
setcookie（'remember_me'，''，$ time（） -  60 * 60 * 24 * 365）; 
setcookie  （'remember_me'，false）; 
unset（$ _ COOKIE ['remember_me']）; 
 redirect（'login'）; 
} 
  code>  pre> 
 
 但是 无济于事。 我只是不能取消设置cookie，当用户检查时记住我选项trys注销它没有发生。
欢迎任何帮助/建议。谢谢 p> 
 
 
我不知道是什么 问题，但我使用jquery插件删除cookie { https://github.com/carhartl/jquery-cookie }。 我包括jquery.cookie.js然后在注销时点击我删除了cookie设置为$ .removeCookie（'remember_me'） p>

答

Use this function please

delete_cookie()

And for native php cookie use

 unset($_COOKIE['remember_me']);

Or use CI function as follows

setcookie('remember_me', null, -1);

That's all

答

with

unset($_COOKIE['some_cookie'])

you don't delete the Cookie on the browser, you unset the variabile $_COOKIE['some_cookie'].

If you want delete the browser cookie you have to set the expiration date in the past:

setcookie("some_cookie", "", time()-3600);

If it doesn't work try setting properly the cookie domain.

Create:

setcookie('some_cookie', null, time() + 3600, "/");

Delete:

setcookie('some_cookie', null, time() - 3600, "/");

cookie未设置无法正常工作
