数据插入到第一个表中，但是获取 ID 号的代码似乎不起作用，并且数据没有插入到接下来的两个表中。代码运行并出现感谢消息，感谢此人提交其详细信息。
一共有三页代码。连接代码在一个文件中。处理代码文件和表单文件。
我不会在此处包含连接代码，因为它有效。
这是表单代码：

共有三个数据库表，分别称为 cakeorder、customerdetails 和首选约会。我不认为多表插入适用于早期版本的 PHP，这是我开始使用的，但我现在使用的是 xampp 5.5.24 和 PHP 5.5.24。我去掉了大部分 html 的格式，所以我可能在这里的某个地方留下了一个悬挂标签，但实际网页上没有。我对PHP不是很精通，所以很多都是通过浏览这个网站来整理的。任何帮助将不胜感激。谢谢
