需要給會員添加一個房屋ID

Question

我將首先告訴你我想要我的代碼做什麼以及它是如何實現的。

成員創建一個帳戶，然後創建一個房子，因此成爲房屋管理員。管理員必須能夠邀請其他用戶通過電子郵件加入該房屋。當用戶發送電子郵件時，我希望電子郵件附有house_id，以便當收到電子郵件的會員填寫註冊表單時，程序已經知道該會員屬於哪個房屋並可以將其保存爲所以在數據庫中。我希望我有道理。

到目前爲止，只要管理員創建房屋，他們的member_id就被分配到房子，所以我可以工作。所以你可以知道房子的管理員是誰。我無法將house_id添加到成員表中，以便在成員表中我可以看到哪個成員是什麼房子的一部分。

我有一個會員類，會員DAO，房子類和houseDAO。

我想知道是否有人可以幫助我，因爲我非常難過。

對不起，如果我沒有解釋清楚，因爲我對這門語言很陌生。 在此先感謝。

看起來你是在正確的軌道上。我認爲你需要在成員類中調用這個函數：

public function setHouseID($h) { $this->house_id = $h; } 

從House類的構造函數中。如前所述，除非每個房屋只需要一名成員，否則您將需要一張單獨的子表來存儲houseid/memberid配對。
