Answer 1

firstly you have to include cookie helper as I mention in the comment section

After that in your controller

public function loginaction()
    {
        $this->load->helper('cookie');
        $email=$this->input->post('email');
        $password=$this->input->post('password');
        $where = array('email'=>$email,'password'=>$password);
        $tbname='login';
        $query = $this->Insert_Model->viewdata($tbname,$where);

                if(empty($query))
                {
                    $data['msg']="Invalid email or password";
                    $this->load->view('login',$data);
                } 
                else 
                {
             //first you have to delete old cookie and create new one
                delete_cookie("email");
                delete_cookie("password");
                if ($this->input->post('remember') == 'true') {

                  $userName = array(
                    'name' => 'email',
                    'value' => YOUREMAIL,
                    'expire' => '86500',
                    'prefix' => '',
                    'secure' => FALSE
                  );
                  $this->input->set_cookie($userName);

                  $password = array(
                    'name' => 'password',
                    'value' => YOURPASSWORD,
                    'expire' => '86500',
                    'prefix' => '',
                    'secure' => FALSE
                  );
                  $this->input->set_cookie($password);
                }
                    redirect('dashboardv1');
             }
    }

Get the cookie you can use below code

<?php echo get_cookie('email'); ?>
<?php echo get_cookie('password'); ?>
