我是新的到PHP/HTML/JAVASCRIPT和Stackoverflow等。但是，我與我的表單的唯一障礙是「一個字段，不需要數據」在用戶輸入上）阻止成功提交。例如，當我刪除了「isset（$ post [number2]）等等，它工作得很好！我如何包含必要的issets並接受空白條目以成功提交我的PHP表單？我希望我已經解釋得很好？很抱歉的命名方案，並在此先感謝一下代碼：當可選輸入字段爲空時，PHP註冊表單失敗

請不要只發布您的代碼，並期望我們爲您解決它。 – Darren
從語句中排除'isset（$ post [number2]）'，並在嘗試使用它之前檢查它是否已設置。例如：'if（isset（$ post [number2]））$ anyVar = $ post [number2];' – Kimmax
您是否也可以發佈您的HTML代碼？ –
