ecshop用户登录问题及ecshop购物车问题解决办法

关于ecshop2.7.0在部分IE浏览器下丢$_SESSION的问题、ecshop 用户登陆后自动跳出的问题

经查常是$_SESSION丢失，在网上查找发现IE6也有不少SESSION丢失的问题，这时，就要通过COOKIE来找回登录状态，但是 includes\modules\integrates\ecshop.php这个整合自身会员的类中没有重写integrate.php中的check_cookie()方法导致,验证cookie时返回的username为空，丢失了登录状态，在ecshop.php中重写了此方法后一切正常了：

/**
     * 检查cookie
     *
     * @access  public
     * @param
     *
     * @return void
     */
    function check_cookie ()
    {
        if ( isset($_COOKIE['ECS'])  && isset($_COOKIE['ECS']['user_id'])  && isset($_COOKIE['ECS']['password']))
        {
      $ecs_user_id   = $_COOKIE['ECS']['user_id'];
   $ecs_user_pass = $_COOKIE['ECS']['password'];
            $sql = "SELECT " . $this->field_name ." AS user_name".
                   " FROM " . $this->table($this->user_table) .
                   " WHERE ".$this->field_id." = '$ecs_user_id' AND ".$this->field_pass." = '$ecs_user_pass'";
            $username = $this->db->getOne($sql);
            if ($username && ($this->charset != 'UTF8'))
            {
                $username = ecs_iconv($this->charset, 'UTF8', $username);
            }
            return $username;
        }
        else
        {
            return '';
        }
    }
