嘿，对不起，如果这个问题可能被问得太多，但我在网站上看到的问题都没有帮助我，而且标题指出我有一个插入查询，可以为我正在制作的网站创建一个帐户但是当我按下提交按钮时它什么都不做......只需刷新页面。
注意：包括数据库。 网站的这一部分包含在signup.php中，而在signup.php中包含了连接文件。 经过测试后我可以从connect.php中获取，所以我不认为那是问题所在。 尽管这并不能证明为什么代码不会一直运行。
经过故障排除和测试后，我发现删除了这部分代码：
if (
$username_error_message_status = false
and $password_error_message_status = false
and $email_error_message_status = false
and $bot_check_error_message_status = false
) {
代码工作但插入查询语句没有。因此，任何形式的帮助都将受到赞赏并感谢阅读。

您的删除if if query应如下所示：
if (
$username_error_message_status == false
and $password_error_message_status == false
and $email_error_message_status == false
and $bot_check_error_message_status == false
) {
如果要比较值，则需要在if语句中使用double equals（==）而不是单个（=）。
