【问题描述】：
所以我有两个页面，两个页面都有一个输入字段，如果用户填写输入字段并转到下一页，他们将在表单的位置看到新内容。所以它基本上就像“填写此表格并显示新内容”。无论您是在 A 页还是 B 页填写表格，其他页面都会识别您是否已填写。有意义吗？
只要您不刷新页面或进入其他页面（而不是单击提交输入），它就可以工作。
我在这里做错了什么？

-
你没有使用任何会话变量；刷新重新加载页面 http 是无状态的，它的工作方式与我目前期望的一样
-
我添加了 $_SESSION['treasure'] = $_POST['treasure'];到页面顶部，它仍然无法正常工作。我错过了什么？用户点击提交后，我希望隐藏输入字段并显示新 div 与其他内容。也许这是不可能的？
