我想在我的html中添加一个表单，它将得到12个输入框并将其保存到mysql。但它的回应失败，因为可能提交按钮。因为如果对于isset提交按钮，则else是转发消息。 代码为我的HTMLphp - 提交按钮不工作在isset

我还没有作出任何验证呢。并且我正在尝试使用msqli和数据库，表正在连接，那么为什么错误即将到来？我只是提交按钮来插入文档。我应该怎么做才能防止失败信息。提前致谢。 :)
[使用if（isset（$ \ _ POST \ ['submit'\]））在脚本打开时不显示回显不工作]（https://stackoverflow.com/questions/7775512/using-ifisset -postsubmit-to-not-display-echo-when-script-is-open-is-not） – JaxCze
