$_POST = array( );

错了，去掉这一行。

$_POST是一个array()你不必声明这个。

可以解决您的问题的事情：

mysql_query($query) 或 die(mysql_error() . ' ' . $query);
不要清除帖子数组
不要抑制数据库连接或至少将错误放入模具中

您可能应该解决的问题，但可能不是您的问题：

$sql注入通过将变量放入sql而不转义
他们使用 mysql 而不是 mysqli 验证数据，做
html 开始使用单选按钮后的控制器内容，例如
复选框没有为您的 url 使用绝对路径
不要使用 root 作为你的用户名 db 并且没有密码
头部和身体之间不应有 html。

另外我不确定您是否可以将“”作为自动增量ID。我会把 Null 放在那里。更好的是，我会明确地将要添加的列放入表中。如果你不这样做，你以后会很头疼……说你有相同的插入到 1000 个位置……好吧，你添加一个列，现在你必须更新 1000 个位置。

此外，我会回显您所做的 sql 语句，并尝试通过命令提示符或 phpmyadmin 运行它。
