創建一個表，點擊後，更新文本文件

我想創建一個網站，允許人們檢查他們有的當前「積分」以及他們收到這些積分的原因。 E.G：拿出5分拿出垃圾，拿到10分洗碗。創建一個表，點擊後，更新文本文件

儘管我已經爲用戶名和密碼設置了實際積分系統和數據庫，但我無法爲自己的生活制定出如何實現管理員添加積分的前端方式，並給出了原因，這將顯示在他登錄後登錄到用戶頁面任何幫助將不勝感激謝謝

在下面的答案中添加了一些代碼，以便您開始使用 – Trevor

您需要一個窗體（在html中）有一個下拉的用戶，一個文本框的原因和文本帶提交按鈕的點框。點擊後，它將返回到服務器上的一個php文件，該文件使用$_GET或$_POST獲取信息，然後使用mysqli_ php函數更新mysql數據庫。然後，php文件可以顯示成功/失敗以及任何其他可能想要顯示回管理員的信息。

希望這些步驟，你可以使用谷歌，並找到相應的代碼，實際上使得它發生，如果你被卡住，回到這裏，告訴你有什麼到目前爲止，人們會很樂意提供幫助。

編輯：這是聖誕節，我覺得寫一些代碼，所以這是一個粗略的開始，你的工作。有很多，你將能夠改善。您還需要創建一份報告，以顯示它的進展情況，但在這裏可能有點多。祝你好運，享受。

非常感謝您的回答，這非常有幫助。關於這段代碼我只有一個問題。當我將id_task鏈接到我的主home.php文件時，它只顯示爲數字（例如1代表第一個任務，而不是實際的第一個任務），我怎樣才能讓它顯示爲實際的措辭？再一次，非常感謝你爲這個代碼，這是一個巨大的幫助 – Anthony

做一些類似於使用switch（$ id_task）和幾個case語句的代碼約2/3的方式。它基本上將$ id_task（一個數字）轉換爲$任務一個人類可讀的名字。 – Trevor

你的代碼現在完美運行，一切都運行正常，非常感謝你。只是想知道，是否有可能創建另一個函數，如totalPoints，它基本上將所有id_points一起添加在同一個id_child下 – Anthony
