Php 如何在MYSQL中每次点击按钮更新多行表单？

我正在开发一个php网站，为一家电气设计公司的地面激光扫描数据导出排序数据。当一行数据出现时，表单在MYSQL中会很好地更新，但当我显示两行或更多行数据时，当单击submit but时，多行数据会相互冲突

我的目标是分别对每行数据进行排序，并在单击行上的submit时通过MYSQL进行更新。但正如我所说，多行冲突。我可以告诉您如何对其重新编码，以指定仅在某一行上以表单形式输入的数据吗

问题还源于希望通过表单显示每个单元格中的当前现有数据，以便我知道输入了哪些数据，哪些数据没有输入

我为不整洁的编码深表歉意，您可能会认为我对这一点非常陌生。这不是我的职业

哦，上帝，那些回声。使用a你需要把每一行都变成一个单独的表单。是的，我只是赶时间，哈哈，总有一天我会整理一下。你可以将html元素名称指定为数组，即name=pole_length[]，name=pole_type[]等等。现在浏览器发送所有信息，PHP将其解析为数组。因此，在PHP中，您可以使用for循环或foreach中的索引来访问它。只需打印\u r$\u POST即可查看结果。
