在这里，我修改了您给出的URL中的代码。

function _yoursite_get_author_post_type_counts() {
    static $counts;
    if (!isset($counts)) {
        global $wpdb;
        global $wp_post_types;
        $sql = <<<SQL
        SELECT
        post_type,
        post_author,
        COUNT(*) AS post_count
        FROM
        {$wpdb->posts}
        WHERE 1=1
        AND post_type NOT IN (\'revision\',\'nav_menu_item\')
        AND post_status IN (\'publish\',\'pending\', \'draft\')
        GROUP BY
        post_type,
        post_author
SQL;
        $posts = $wpdb->get_results($sql);
        foreach($posts as $post) {
            $post_type_object = $wp_post_types[$post_type = $post->post_type];
            if (!empty($post_type_object->label))
                $label = $post_type_object->label;
            else if (!empty($post_type_object->labels->name))
                $label = $post_type_object->labels->name;
            else
                $label = ucfirst(str_replace(array(\'-\',\'_\'),\' \',$post_type));
            if (!isset($counts[$post_author = $post->post_author]))
                $counts[$post_author] = array();
            $counts[$post_author][] = array(
                \'label\' => $label,
                \'count\' => $post->post_count,
                \'type\' => $post->post_type,
                );
        }
    }
    return $counts;
}
$user_id = get_current_user_id();
$counts = _yoursite_get_author_post_type_counts();
$custom_column = array();
if (isset($counts[$user_id]) && is_array($counts[$user_id]))
    foreach($counts[$user_id] as $count) {
        // $link = admin_url() . "edit.php?post_type=" . $count[\'type\']. "&author=".$user_id;
        // admin_url() . "edit.php?author=" . $user->ID;
        // $custom_column[] = "\\t<tr><th><a href={$link}>{$count[\'label\']}</a></th><td>{$count[\'count\']}</td></tr>";
        echo $count[\'label\']. "  ".$count[\'count\']."<br />"; 
    }
}
