Answer 1

Your value already stored in cookie, $this->input->set_cookie($cookie) this will only create the cookie. If you want to check cookie value set or not than you can use like that:

$cookie = array(
  'name'   => 'demo',
  'value'  => 'Hello i m cookies which saved in this broswer',
   'expire' => '86500',
);
$this->input->set_cookie($cookie);

if(isset(get_cookie('demo'))){ // check cookie value
  echo "success"; // replace with your code
}
else{
  echo "failed"; // replace with your code
}

get_cookie('demo') will return the cookie value.

Make sure, you are using cookie helper in your file, you must need to include cookie helper:

$this->load->helper('cookie');

Answer 2

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

this function returns NULL thats why your condition is not working fine. your cookie is being set

use $this->input->cookie('your cookie name') to check your condition

public function set()
{
    $this->load->helper('cookie');
    $cookie = array(
      'name'   => 'demo',
      'value'  => 'Hello i m cookie',
      'expire' => '86500'
    );
    $this->input->set_cookie($cookie);
    if ($this->input->cookie('demo')) {
        $data['data'] = array('message' => 'cookie successfully set');
        $this->load->view('your view', $data);
    } else {
        $data['data'] = array('message' => 'Something went wrong while creating cookie');
        $this->load->view('your view', $data);
    }
}

Answer 3

In my case after hours of debugging I realized that cookie_secure was set to true for local development.

So, do an easy check ;

If domain is not https and cookie_secure is set TRUE in config.php, cookies simply will not be set. Change to FALSE and it will be set in both http and https.
