我已经编写了如下所示的代码，但是在运行时（即用户尝试注册时）没有任何反应。 所有主要的编码都完成了，我不知道问题出在哪里。
我已经考虑了过程中应该采取的所有步骤，即验证用户数据，检查数据库中当前的用户名。
如果有人可以帮助我并指出正确的方向，我将不胜感激！

我设法使代码正常工作，但是现在我在注册过程中遇到了这个问题，如果if语句中的条件为true，则系统会提示用户修复用户插入的那些问题，但目前即使这些条件不符合用户用户的注册条件，不是这样的。
这是改进的php代码

在数据库中插入数据时，应检查现有数据。无论是否存在，您都可以通过执行以下操作来实现：在表名查询中执行Select *，然后使用循环将所有列与输入字段一一比较。
