こんにちは、マルチセクションのテーブルビュー設計を持つすべての m
searchcriteria セクション (このセクションは必須) を除いて、すべての選択が OR 条件にある選択された行に基づいてフィルターを適用したい、今私が達成したいのは、すべての選択を保存し、ユーザーがクリックしたときにデータをフィルターすることですボタンを適用します。これを達成する方法。助けてください。
注：今後データベースを使用したくないので、選択したすべての値を POST メソッドを使用して投稿する必要があります。

助けてください.私はたくさんグーグルで検索しましたが、私のシナリオの魂を見つけることができません.
