私は次のページのリンクや他のものをクリックしたときとは別の、異なる結果(閉じたオープン、保留中、すべて)とページ付けのためのさまざまな状態として、ページ私はステータスセットが失われた、例えば「閉じられました」を失い、すべての結果が表示されます。ステータスとページネーションのmysqlの問題
私はphpとmysqlを使った初心者ですので、実際にはどのように実装すればよいのでしょうか。セッションが保存されていれば、状態がまだ設定されている可能性があります。
コードをご覧ください。
本当にありがとうございました。

こんにちは、それは大きな感謝、多くの感謝を働いた。今は小さな問題ですが、新しい状態をクリックすると、np(ページ数)と行の開始のクエリ文字列を削除する方法を検討する必要があります。 3ページ目で結果の1ページしかない別の状態をクリックすると、ページ3の開始= 12を表示するクエリ文字列のために結果が得られません。理にかなった希望。あなたはなにか考えはありますか? – Maximus
特定のビューステートにいくつのレコードがあるのかをカウントする必要があると思います。レコード数がページよりも少ない場合は、ページ1に設定します。 – ace
$ _SERVER ['REQUEST_URI'] = preg_replace( '!&startoftable =。*!'、 ''、$ _SERVER ['REQUEST_URI'] ); – Maximus
