我有一個switch語句，它決定了上傳的圖像的文件類型，作爲我的應用程序中的頭像使用，但它似乎有點故障，只要它允許成功註冊，無論是否存在允許的文件類型，並且沒有錯誤消息正在返回。提交的文件類型不被允許。用於個人資料圖片上傳的SWITCH語句

例如，上載在沒有錯誤和「登記成功」的消息的.GIF文件的結果，但是在登錄到配置文件時，上傳的資料照片未示出。我在考慮代碼拒絕文件類型，而不是將它存儲在數據庫中，但仍在處理註冊，而不是取消它，這是它應該做的。
嗨，謝謝你的幫助！不幸的是，你的解決方案似乎都沒有工作。 除了上傳的頭像之外，應用程序已成功提交註冊，因此該支票顯然工作正常，但如果上傳的文件類型無效，則註冊不應繼續進行。 –
不知道我是否得到了你，但看看我的更新。 –
工作完美，非常感謝您的幫助！ –
