我對PHP相當陌生，目前正在進行調查。用戶在單選按鈕上的表單中選擇問題的答案。每個問題有4種可能性，並在每個問題下分組。提交表單時，頁面應顯示每個組的哪個按鈕被選中。目前的代碼是這樣的：顯示在提交表單後選擇了哪個單選按鈕

我得到一個錯誤，說我沒有定義值2變量， 3，4和5，我不知道爲什麼。
請複製粘貼確切的錯誤，你有。我沒有正確地得到你。 – 2013-02-19 12:29:39
注意：Undefined變量：value3在C：\ wamp \ www \ thankyou.php在第106行 與2和4和5的值相同 – RossDoughty 2013-02-19 12:30:33
@RossDoughty：一個建議，如果您的所有單選按鈕組值都相同不要重複開關，而是使用循環。如果你想顯示在謝謝你的頁面中選中的單選按鈕，只需在單選按鈕內部進行回聲檢查。並且將值存入單選按鈕組 – zamil 2013-02-19 12:33:28
