ソーシャル ネットワークを構築していて、mysql の代わりに PDO を実装しようとしていますが、テーブル値を挿入するための PDO の動作バージョンを作成する方法が見つからないため、すべての PDO の実装を完了していません。なぜこれが発生するのかわかりませんが、コードは次のとおりです。タイトルが示すように、私が提供した PDO コードを使用して、すべてのフィールドに入力し、サインアップをクリックすると、ヘッダーの上部に「すべてのフィールドに入力してください」と表示されます。さらにコードが必要な場合 (他の .php ページについては、コメントしてください。何が必要なのかわかりません。一緒に使えることがわかっているものを選びました)。
