Question

因此，我一直在尝试为比赛表创建一个“添加”功能，该比赛表也与加入表相关联，因为比赛有许多与之相关的体育赛事（体育赛事也将包含在许多比赛中））。我已设法创建如下，但它仅限于在下拉列表中根据所选游戏在连接表中添加一行。

现在，如果我不知道可能有多少体育赛事，我该如何创建表格呢？如果使用一个下拉列表，网站将如何创建另一个下拉列表，以便可以选择更多的体育赛事？类似地，控制器如何知道选择了多少个下拉列表，因此x要添加到连接表中的行数？

如果我使用不正确或含糊不清的术语来描述我的问题，我很抱歉。我最近才开始学习和创建网站。

谢谢。

更新： 我可能会根据以下更新的代码找到解决方案。但是我现在停留在插入数据库页面。出于某种原因，当我单击提交时，下一页加载但没有错误，也没有插入行。请帮助：）
