フィルター分類管理ページ区切り
分類管理領域では、ユーザーに関連付けられているメタキーに基づいて分類用語を除外しています。ページネーションはまだ用語の完全な数があると思います。私は同様にページ付けをフィルタリングすることを可能にするフックが存在しますか？私は何も研究しているのを見つけることができません。
私の最良の理論は、ページネーションがどこで生成されているのかを突き止めて、ページ数を決定するために使用しているものすべてにフックすることです。 WordPressのソースコードを見ると、それを可能にするものは何もありません。
編集：これはカスタム投稿タイプ「preschool」のカスタム分類法「preschool_class」用です。以下の現在の機能に使用されているクラス全体を this から変更したものを貼り付けました。

この行は、エディタページの用語をフィルタするものです。
add_filter("list_terms_exclusions", array(&$this, "exclusions"));
除外はこれを返します。
" AND (t.term_id IN ($this->user_classes) OR tt.taxonomy NOT IN ('preschool_class'))"
