所以就像往常一样，我正在编写迄今为止我没有经验的代码。
我要做的是为工作中的一个部门创建一个票据类型系统，用于联系潜在的学生。大多数情况下，我对 HTML 和 PHP 没问题，它正在学习让我难过的 SQL。我什至不确定这一切是否正确。我可能还需要合并 AJAX。基本上，联系人将填写一份表格，其中包含他们想要攻读的学位类型以及联系信息等信息……一切都很好地插入到 SQL 中，但是当我想从我的 viewtable.php 页面编辑它时问题就来了.
这只是工作原型，最终它将有用户登录和其他类似的东西，以及管理控制台等......所以事不宜迟，这是我的可视化代码。如果不够，请告诉我。我会继续研究，但你们可以提供的任何帮助将不胜感激。
