Javascript html表单已成功提交到表单操作，但未能插入数据库（2020年2月20日）

我有自己的申请人评估工具，使用PHP、Javascript和Mysql。表格应填满答案，或在12分钟后自动提交，并将空白字段值设为零。它是全功能的，我会告诉你如何设置它

这应该插入到ghsexam.php中

<script>
time = 720;
interval = setInterval(function() {
time--;
document.getElementById('Label1').innerHTML = "" + time + " seconds"
if (time == 0) {
    // stop timer
    clearInterval(interval);
    // click
    document.getElementById('thebutton').click();            
}
}, 1000)

</script>

危险
插入
。我建议在准备好的语句中使用mysqli。我希望你的连接信息真的在一个单独的页面上，在一个有700权限的文件夹中。
不是一个容器，你不应该有
，但是insert语句在另一个php页面上？好吧，你没有检查任何php或mysql错误，因此，如果您没有收到任何错误消息，您真的不应该感到惊讶。。。
