兩個提交按鈕和1個表單不傳遞值

我有一個PHP文件，它有一個表單和2個提交按鈕，onclick的1個按鈕它必須通過從下拉列表中選擇的值。它不會將值傳遞給接受POST數據的php文件。但是，如果我只有一個按鈕和相同的形式，這工作正常。我在下面找到我的代碼。兩個提交按鈕和1個表單不傳遞值

您的「提交」按鈕打印和PRINT2？ – Mate

@mate是的，是否應該更改名稱以提交兩個按鈕？ – user1114409

@Mate我試圖改變按鈕名稱提交，它不起作用 – user1114409

謝謝夥伴，這工作正常！ – user1114409

太棒了！始終爲名稱變量分配一個更適合您的名稱，供您以及將來需要使用該代碼的任何人使用; – Mate

當然會這麼做！非常感謝，它節省了大量的時間！ – user1114409
