如何让你的WordPress全部文章后台显示字数

// 添加文章字数列
add_filter('manage_posts_columns', 'neijuli_add_column');
function neijuli_add_column($columns) {
    $columns['neijuli_wordcount'] = '字数';
    return $columns;
}

// 链接字数到我们的新列
add_action('manage_posts_custom_column', 'neijuli_display_wordcount', 10, 2);
function neijuli_display_wordcount($column_name, $post_id) {
    if ($column_name === 'neijuli_wordcount') {
        // 获取帖子 ID 并将其传递到 get_wordcount 函数
        $neijuli_wordcount = neijuli_get_wordcount($post_id);
        echo $neijuli_wordcount;
    }
}

function neijuli_get_wordcount($post_id) {
    // 获取帖子，删除任何不必要的标签，然后执行字数统计
    $content = strip_shortcodes(get_post_field('post_content', $post_id));
    $neijuli_wordcount = mb_strlen(preg_replace('/\s+/', '', strip_tags($content)), 'UTF-8');
    return $neijuli_wordcount;
}
