两个提交按钮和1个表单不传递值

我有一个PHP文件，它有一个表单和2个提交按钮，onclick的1个按钮它必须通过从下拉列表中选择的值。它不会将值传递给接受POST数据的php文件。但是，如果我只有一个按钮和相同的形式，这工作正常。我在下面找到我的代码。两个提交按钮和1个表单不传递值

您的 “提交” 按钮打印和PRINT2？ – Mate

@mate是的，是否应该更改名称以提交两个按钮？ – user1114409

@Mate我试图改变按钮名称提交，它不起作用 – user1114409

谢谢伙伴，这工作正常！ – user1114409

太棒了！始终为名称变量分配一个更适合您的名称，供您以及将来需要使用该代码的任何人使用; – Mate

当然会这么做！非常感谢，它节省了大量的时间！ – user1114409
