【问题描述】：
这段代码看起来一切正常，但总是无法提交数据，这可能是什么问题？
我正在为 myphpadmin 数据库使用网络主机 (000webshost)。 该表单曾经提交数据，但由于某种原因它开始失败，我不明白为什么。 提交表单总是显示插入数据失败，其他一切看起来都很好。 我们在网站前端使用 Tailwind css。
这里是html：

Please look into the code above and see if there is any type of error.
Iam updating the same db from android app and another smaller html form and it works but for this bigger one it is failing.

这能回答你的问题吗？ How can I prevent SQL injection in PHP?。同样的技术还可以帮助防止 SQL 中出现意外的语法错误
-
另外，您没有检查真正的 SQL 错误，因此您不知道真正出了什么问题或如何修复它也就不足为奇了。见How to get the actual mysql error and fix it?

看起来你需要一个小例子——你可以在 W3Schools 或 php.net 上找到一个——使用 mysqli_query。然后你可以根据自己的情况进行调整。您也可以尝试打印 $_POST 以查看它是否包含您认为的内容。
