Question

我目前正在为我的网站创建注册页面，我已设法使其工作并将用户添加到我的主表user_info，但是我还有其他表格，我希望系统插入用户进入他们加入时，例如他们的IP地址的日志，问题是我认为这将是一个简单的cas选择用户信息，然后将字段插入ip_address表，但我不断收到错误

“您的SQL语法有错误;请查看与您的MySQL服务器版本对应的手册，以便在第1行附近使用正确的语法”'

无论如何这里是我的整个php脚本的代码，导致错误的新代码行来自第171-176行（代码块底部的最后5行）。

由于

Answer 1

这里遗漏的括号括起来：

"INSERT INTO ip_log (id, ip_log) VALUES ('$id', '$ipaddress'"

添加新插入时出现PHP错误
