PHPクイズを3回簡単にします。各質問はそれ自身のページに表示されます。送信ボタンを押すと変数$ numberは1ずつ増加し、その値はユーザーのブラウザに表示される現在のページを決定します。何らかの形でこの変数が正しくインクリメントしていないように見えます。送信ボタンを押すと、ページは変更されません。私は本当にこのプログラムを実行したいと思います。私はこれがあなたのほとんどのための比較的単純なスクリプトだと思います。誰かがこれを実行するのを助けることができれば、それは非常に高く評価されるでしょう。送信ボタンは何も返しません。特定のページに関連付けられた値はインクリメントされません。

幻想的な答え！ちょうど素晴らしい！私はこれらの変更を加えました（MrTricksの提案に加えて）、すべての正しい回答を入れると、3つのうち2つしかないということを除いて、すべての人が動いています。スクリプトが質問の1つの値を正しく取得しない可能性がありますか？ – kmimage
@kmimage：あなたの3番目の答えフィールド ''はIDでなく名前が必要です。名前がないので送信されていません。 – animuson
