グリッド内のすべてのユーザー（およびPaginate）を出力するようにWP_LIST_AUTHOR関数を変更する

Question

タイトルはそれをすべて言います。

私はWP_LIST_AUTHORを取り、それを修正してオリジナルの多くのオプションをそのままにしながら、著者のリストだけではなくもっと多くのメンバーディレクトリを作成しています（そして私はもっと下に追加する予定です）。私の最初の仕事はそれにページネーションを組み入れることでした、そして、私はそれをうまくやることができました（以下のコード）（それはまだそれほどきれいではありませんが）。

私は今、それをテーブルに組み立てることを望んでいます（たぶん1ページあたり15の結果、3x5のグリッドで。行 - セルセルセル行 - セルセルセルなど）。これを実行する最善の方法についてはよくわかりません。あるいは、コードの現在の構築方法でこれを実行できる場合でも、アドバイスやリンク先のリソースは大歓迎です。私は本当に物事を一緒にハッキングしているだけです;）また注意してください。サイトはs2memberプラグインを使用しており、どんなコードでもその機能を台無しにする必要はないでしょう。

Answer 1

あなたのスニペットは従うには少し冗長すぎるので（そしてここで遅くなります）、これはもう一つの選択肢です。 wp_list_author()を偽造することはここでやり過ぎるかもしれないと思います。ユーザー検索を利用して、必要な著者の部分を正確にスライスする方がよりエレガントです。

これが私が思い付いたいくつかのサンプルコードです。

add_action('pre_user_query','offset_authors');

$authors_per_page = 1;
$current_page = absint(get_query_var('page'));

function offset_authors( $query ) {

    global $current_page, $authors_per_page;

    $offset = empty($current_page) ? 0 : ($current_page - 1) * $authors_per_page;    
    $query->query_limit = "LIMIT {$offset},{$authors_per_page}";
}

wp_list_authors();
