php - isset条件在不同的点击下表现不同

Question

我正在开发一个页面，其中有 5 章测验的列表，每章都有 3 组按钮(出现、请求、已请求)，这些按钮根据某些数据库条件出现。当用户第一次出现特定章节的测验时，出现的按钮是“出现”。现在，如果他尝试在该章的测验中失败，按钮将变为“请求”(因为用户现在需要管理员的许可才能重新出现参加测验)。现在，当他单击“请求”按钮时，它会执行一组数据库操作，出现的下一个按钮是“请求”。这对于所有章节都适用，但仅当用户“请求”前一章并尝试请求下一章时，按钮的状态仅保持“请求”而不是“已请求”。我不知道为什么在提交时没有将其状态从“请求”更改为“已请求”。以下是我的代码，请帮助我，这将是我的救星，非常感谢。

是的，现在终于排序了。支架放错位置，因此解决了。 :)
