fatal error: Call to a member function bind_param() on a non-object 

書類を作成し、私はこのエラーを持っていますconfirmadd 何が問題になっているのですか、なぜこれが起こっているのかわかりません。 以前と同じように多くのクエリを実行しましたが、すべてエラーなしで動作します。

Answer 1

まず、準備中の文を何らかのエラー処理でラップして、何が起きているのか、そしてMySQLが表示しているエラーを確認する必要があります。 MySQLのエラーは通常、かなり有益で、クエリのどこで失敗しているかを伝えます（通常、問題の発見に役立ちます）。

この場合、私はそれが問題の原因となっている「キー」列であると確信しています。あなたが列名としてそれを使用する場合、「キー」はMySQLの意味でreserved wordであるあなたは、バッククォート

INSERT into CONFIRM (user_id, username, `key`) VALUES(?, ?, ?) 

でそれをラップする必要がある。しかし、このようなケースではあなたにも、列の名前を変更を検討してください。
