我想在wp登录表单中使用codeignider登录表单会话

public function check_login()
{     

    if($this->session->userdata(\'logged_in\'))
    {
        redirect(\'/\');
    }
    //Set Page Title
    $data[\'title\'] = "Check Login"; 

     $username = $this->input->post(\'username\');
     $email = $this->input->post(\'username\');
     $password = $this->input->post(\'password\');        
     $password = hash(\'sha1\',$password);
    echo (int)$is_admin = $this->loginmodel->user_login($username, $email, $password);
       $_SESSION[\'sumit\'][\'puri\']=$this->session->userdata(\'id\');
    // print_r($is_admin);
    //
}
