このコードで何が問題なのか分かりませんが、FULL JOINを使用するとJOINされたテーブルでページングが継続します。私はJOINedテーブルが最初のテーブルより多くの行を持っている場合、結果は空のhtmlテーブルですが、多くのページがあることを意味します。 JOINedテーブルを削除すると、結果は5-6行の通常のテーブルになります。しかし、JOINとテーブルがinfoで5-6行、空のセルで100になったとき。 このコードのアドバイスはありますか？あるいは、私は他のコードを使用する必要がありますか？私はページングがそのような痛みであることを信じることはできません、良い作業コードを見つけることができません。 ありがとうございます！FULL JOINを使用したPHP pdoのページ付け
