wordpressで複数人で投稿予定のサイトを作成しております。

それぞれの投稿者のページに `get_calendar`
でカレンダーを表示し、投稿のある日にリンクを貼りたいのですが、現状全ての投稿者のリンクが貼られてしまう状況です。

例:  
aさん 1日、3日、5日更新 →カレンダーの1、3、5にリンクが貼られて欲しい  
bさん 2日、4日、6日更新 →カレンダーの2、4、6にリンクが貼られて欲しい  
現状：→カレンダーの1、2、3、4、5、6にリンクが貼られている

カレンダーを表示しているタグは以下です。

```

    <?php get_calendar(); ?>
    
```

お知恵を貸していただけますと助かります。宜しくお願い致します。

wordpress
投稿者ごとのカレンダーを表示したい
自己解決できました！  
今後同じような方のためにソースコードを掲載しておきます。

手順：  
1.wp-includes/general-template.phpの中にある、get_calender()関数を、functions.phpにコピー  
2.author idを取得し変数に格納（$uid）  
3.全てのSQL文のWHERE句内に post_author = $uidを挿入

```

    //投稿者ごとのリンクをカレンダーに表示
    function get_custom_calendar($initial = true, $echo = true) {
        global $wpdb, $m, $monthnum, $year, $wp_locale, $posts, $uid;
    
        //author IDを取得する
        $uid = get_the_author_meta('id');
        $key = md5( $m . $monthnum . $year );
        if ( $cache = wp_cache_get( 'get_calendar', 'calendar' ) ) {
            if ( is_array($cache) && isset( $cache[ $key ] ) ) {
                if ( $echo ) {
                    /** This filter is documented in wp-includes/general-template.php */
                    echo apply_filters( 'get_calendar', $cache[$key] );
                    return;
                } else {
