        if ($this->check_user($username, $password) > 0)
        {
            if ($this->need_sync)
            {
                $this->sync($username,$password);
            }
            $this->set_session($username);
            $this->set_cookie($username, $remember);

修改为

 function login($username, $password, $remember = null)
     {

         if(is_email($username))
{
$sql = "select ".$this->field_name." from ".$this->table($this->user_table)." where ".$this->field_email."='".$username."'";
$username = $this->db->getOne($sql);
if(!$username) return false;
}
         if ($this->check_user($username, $password) > 0)
         {
             if ($this->need_sync)
             {
                 $this->sync($username,$password);
             }
             $this->set_session($username);
             $this->set_cookie($username, $remember);

             return true;
         }
         else
         {
             return false;
         }
     }
