    WordPress・PHP初心者です。
    カテゴリー名をクリックした時にアンカーリンクで指定の場所へ飛ばしたいと考えています。
    現在、下記のソースでカテゴリーリストを表示しています。
    ——————————–
    <div class=”sidebar_box”>
    <ul class=”cat”>
    <?php wp_list_categories(‘title_li=’); ?>

    </div>
    ——————————–

    この状態で、カテゴリーの1つをクリックすると、ページの一番上から表示され、
    URLでは「http://○○.com/category/○○/」と表示をされます
    ヘッダがとても長いため、これを、カテゴリー名をクリックした時に指定の場所へ飛ばすアンカーリンクを設置したいと考えています。
    URLでは「http://○○.com/category/○○/#koko」と表示したいです。

    そこで、
    wp-includesの中にある、【category-template.php】の中で「#koko」を追加することが出来ると思うのですが、また記述の方法など教えていただけますでしょうか。

  • URL にハッシュを付け足すだけで良いなら、以下をテーマの functions.php に追加で OK◎

    <?php
    add_filter( 'wp_list_categories', 'my_wp_list_categories', 10, 2 );
    function my_wp_list_categories( $output, $args ) {
      if ( isset( $args['hash'] ) ) {
        $hash = esc_attr( $args['hash'] );
        $output = preg_replace( '/href=[\'"]([^\'"]*)[\'"]/i', "href='$1#$hash'" , $output );
      }
      return $output;
    }

    ?>

    で、wp_list_categories() で以下のようにハッシュを指定します。
    <?php wp_list_categories( array('hash'=>'koko') ); ?>

    #WordPress のコアソースは皆持ってるから貼付けなくて OK◎

    kzさま

    ソースを全て記述してしまい、ごめんなさい。
    本当に、ありがとうございます。

    いただいた、ソースの「add_filter・・・・・return $output; }」をfunctions.phpの一番下の「?>」の前の部分へ追加したのですが、
    アップをすると、下記のエラーが出てしまいました。。
    Fatal error: Call to undefined function add_filter() in /home/users/2/lolipop.jp-dp○/web/testblog/wp-includes/functions.php on line 4303

    現在本番アップ済みのサイトの修正なので、テストディレクトリでテストをしているのですが、本番が、3.0.3なのに対して、テストの方のバージョンが3.1だったため、3.0.3の古いバージョンに合わせる作業も行ったので3.1と3.0.3の両方のバージョンで試したのですが、どちらのバージョンでも同様でした。

    また、今回のハッシュの追加はカテゴリーに限らず、記事タイトル、アーカイブについてもリンク先の場所を同じところへ指定したいと思っています。
    カテゴリーの追加方法が分かったら、他は自分で考えて出来るかなと思ったのですが、もし、サイト内のリンクへ一括でハッシュを付けることが出来るのでしたら、教えていただけますでしょうか?

    Fatal error: Call to undefined function add_filter() in /home/users/2/lolipop.jp-dp○/web/testblog/wp-includes/functions.php on line 4303

    というエラーからもわかるとおり、間違ったfunctions.phpに追加しているからですね。

    kzさんは「テーマの functions.php に追加」と追加する場所を教えてくれていますよ。

    テーマにていただいたソースをアップして、ハッシュタグをつけることが出来ました!
    本当にありがようございます。

    chestnut_jpさん

    ご指摘いただけなければ、気付けませんでした。
    本当にありがとうございます。

    これからwpについて勉強しようと思います、本当にありがとうございました!
