我很难弄清楚如何将子页面的标题显示为div的id“其他新闻”是父页面主页（39）的同级

我想要这样的东西：

<div class="wrapper" id="news">
content
</div>
<div class="wrapper" id="othernews">
content
</div>

function content_block( $atts, $content = null ){

extract( shortcode_atts( array(
    \'type\'          =>      \'white\'

), $atts));

$childArgs = array(
    \'post_type\'         =>      \'page\',
    \'parent_page\'       =>      39
);

$child = new WP_Query($childArgs);

if ($child->have_posts()) {

    while ($child->have_posts()) {

        $child->the_post();

        if ($type == \'white\') {
            $return .= \'<div class="col-white">\';
                $return .= \'<div class="wrap" id="\'. get_the_title() .\'">\';
                    $return .= do_shortcode($content);
                $return .= \'</div>\';
            $return .= \'</div>\';

        } else
        if ($type == \'grey\') {
            $return .= \'<div class="col-grey">\';
                $return .= \'<div class="wrap" id="\'. get_the_title() .\'">\';
                    $return .= do_shortcode($content);
                $return .= \'</div>\';
            $return .= \'</div>\';
        }

        wp_reset_query();
        return $return;
    }
}

}
