私はnbabdl_spillerという名前のテーブルを持っています。プレイヤーテーブルがあります。データベースを編集してもコードが追加されない
spiller_id
spiller_navn (player name)
spiller_position
spiller_ligahold (player league team)
spiller_alder (player age)
spiller_lon1 (player salary year 1)
spiller_lon2
spiller_lon3.
私はうまく選手を作成することができます - しかし、フィールドspiller_id、spiller_navn、spiller_positionとspiller_alderが使用されている場合、私は唯一のプレーヤーを編集することができます - 私はbdl_update.phpに多くを追加しようとすると、それを変更を加えずにbdl_index.phpに返信してください。
私は間違っていますか？私はmysqli_stmt_bind_paramについて読んでみましたが、それは私を助けませんでした。
まず、ものではなく、最終的にはあなたがフィールド/変数を参照することができますbdl_index.php 1その後、働いているコード：
<?php

だとかなりまともな量のコード。実際の問題に関係のないものはすべて取り除く必要があります。問題コードがどこにあるのかを試してみるために、多くの人々がそれをすべて通過することはありません。現在、「Where's Waldo」のコードバージョンです。 –
貼り付けたコードの多くは、この質問とは関係ありません。適切なコードを整理してください。また、すべてのことをエコーしないでください。それは維持することが難しいだけの混乱です。必要に応じて生のHTMLを使用し、サーバーでphpを使用しますが、クライアント（javascript）を使用して必要なデータを取得して投稿することが好ましいです。 – Jonast92
