私はphpページネーションチュートリアルを使用しました: http://www.phpeasystep.com/phptu/29.html。そして、それは簡単だと言ったので、私は何の問題も期待していませんでした. しかし、私は1つに遭遇しました。最良の結果を得るには、私のソース コードを確認する必要があることがわかったので、提供します。問題は、問題なくクエリを実行し、メンバーが正しい場合にのみページに特定のデータを表示し、ページごとに数個に制限することです...ただし、次のコメントをもっと見るために変更しようとしても、値は変更されませんページ。

問題は、プロファイルが異なるユーザーごとに持っている ID に応じて、プロファイルの異なるデータを開く $targetpage である可能性があると思われます。しかし、これを修正する方法がわかりません。または、これが問題である場合でも...何が問題なのか誰にもわかりますか? （修繕）
