我不理解您在“子级”查询和“顶级”查询之间所做的区分，但这就是我为页面提取子级的方式。

$children = get_children(
    array(
        \'post_parent\'   => $servid,
        \'post_type\'     => \'page\',
        \'post_status\'   => \'publish\',
        \'orderby\'       => \'menu_order\',
        \'order\'         => \'ASC\'
)); ?>

$page_children = get_pages(
 array(
  \'child_of\'    => $post->ID,
  \'post_type\'   => \'page\',
  \'sort_column\' => \'menu_order\',
  \'order\'       => \'ASC\'
 ));

下面是一个使用类别而不是页面的示例，但您可以使用父级信息查询信息within 另一个循环：

// checking current taxonomy to see if it has child categories if it doesn\'t then we\'re out of sub categories and should show the current categories products
$args = array(
    \'type\'       => $taxfunc_post_type,
    \'hide_empty\' => 1,
    \'orderby\'    => \'name\',
    \'order\'      => \'ASC\',
    \'taxonomy\'   => $taxfunc_tax_name
);

$categories = get_categories($args);
$categories = wp_list_filter($categories,array(\'parent\'=> $term_id));

foreach($categories as $category) {

    // setup the cateogory ID
    $cat_id = $category->term_id;
    // Get category name
    $cat_name = $category->name;
    // Get category count
    $cat_count = $category->count;
    //get the category url
    $cat_url = get_term_link( $category->slug, $taxfunc_tax_name );

    echo \'<div class="cat-block">\';
    echo \'<header>\';
    echo "<h3>";
    echo $cat_name;
    echo "</h3>";
    if ($cat_count > 0) {
        echo \'<a href="\'.$cat_url.\'">\';
        printf( _n(\'1 profile\', \'%s profiles\', $cat_count,\'mouldings\' ),$cat_count );
        echo \'</a>\';
    }

    $subcat_args = array(
        \'type\'       => $taxfunc_post_type,
        \'hide_empty\' => 1,
        \'orderby\'    => \'name\',
        \'child_of\'   => $cat_id,
        \'order\'      => \'ASC\',
        \'taxonomy\'   => $taxfunc_tax_name,
        \'pad_counts\' => 1
    );
    $subcategories = get_categories($subcat_args);
    $subcat_count = count($subcategories);
    if ($subcat_count > 0) { echo \' <a href="\'.$cat_url.\'">\'; printf( _n(\'1 subcategory\', \'%s subcategories\', $subcat_count,\'mouldings\' ),$subcat_count ); echo \'</a>\'; }
    echo \' <a class="view-all" href="\'.$cat_url.\'">\'.__(\'View all\',\'mouldings\').\'</a>\';
    echo \'</header>\';

    echo \'</div>\';
