メンバーに家のIDを追加する必要があります

Question

私は自分のコードで何をしたいのか、どのようにするのかを教えて始めます。

メンバーはアカウントを作成してから家を作成するため、家の管理者になります。管理者は、他のユーザーを招待して、電子メールで家に入ることができる必要があります。ユーザーに電子メールが送信されると、電子メールにhouse_idが添付されていて、電子メールを受け取ったメンバーが登録フォームに記入すると、そのメンバーはメンバーがどの家にいるかを既に知っていて、データベース内で私は理にかなっているといい。

これまでのところ、管理者が家を作成したときに、そのメンバーIDが家に割り当てられていれば、私は働くことができます。だからあなたは、家の管理者が誰であるかを知ることができます。 house_idをメンバーのテーブルに追加することはできません。そのためメンバーテーブルでは、メンバーがどの家の一部かを見ることができます。

メンバークラス、メンバーDAO、ハウスクラス、houseDAOがあります。

私は非常に困惑しているので、誰もがこれを手伝ってくれるのだろうかと思っていました。

申し訳ありません申し訳ありませんが私はこの言語には非常に新しいので、十分にはっきり説明していません。 ありがとうございます。

あなたは正しい軌道にいるようです。私はあなたがメンバークラスでこの関数を呼び出す必要があると思う：

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

ハウスクラスのコンストラクタからです。そして言及したように、家ごとに1つのメンバーしか必要としない限り、houseid/memberidのペアを格納するために別の子テーブルが必要になります。
