                </table>
            </form>
        </body>
</html>

当我第一次进入页面时，如果我使用链接转到另一个页面，再返回时也没有任何问题，但是当我在此页面上并刷新时，它不会有任何问题。它变成空白，全屏，这是我的问题。 是isset烦人的事还是对POST做任何事，因为他想获取信息，但上一页是此页面，因此他无法识别该信息？ PS：语言是荷兰语，别介意：D

我无法发表评论-因为有50名代表...

评论多于答案： 

error_reporting(E_ALL); 
ini_set('display_errors', 1);

如果您遇到问题，请打开错误报告功能。

而且您的代码有点混乱。

您在-Tag之前输出html。 收盘价牌在哪里？ ？

格式化您的代码，您的错误将减少50％以上。 也许这样做，仅是一个例子，请再次仔细检查：
