codigneter setcookie在我的情况下不起作用

Question

if(isset($_COOKIE['fb_userId'])){
    setcookie('fb_userId', $userId);
}

I put this within one of my controller, the cookie named userId should be inserted after the call right? but I checked the resources tab of my chrome, I don't see anything..

I also tried the helper method like this

$this->input->set_cookie($cookie_arr);

Answer 1

In your code above, it will only set the cookie if the same cookie name (fb_userId) already exists.

Try use the following code:

if(!isset($_COOKIE['fb_userId'])){
   setcookie('fb_userId', $userId);
}

I've add the ! before your isset()

Answer 2

if you want to set cookie in Codeigniter than you can use that code

 $this->load->helper('cookie');
     $cookie = array(
       'name'   => 'testcookie',
       'value'  => 'test value',
       'expire' => '86500'
      );

     $this->input->set_cookie($cookie);

     echo $_COOKIE['testcookie'];
