您可以随时使用page_template 过滤器告诉WordPress对某个父级的所有子页使用特定的页面模板。这就像创建一个特殊的页面模板一样简单，让我们调用它page-wpse-person.php.

现在，只要在people 正在查看。为了举例说明，让我们假设people 是10

add_filter( \'page_template\', function ( $template ) use ( &$post )
{
    // Check if we have page which is a child of people, ID 10
    if ( 10 !== $post->post_parent )
        return $template;

    // This is a person page, child of people, try to locate our custom page
    $locate_template = locate_template( \'page-wpse-person.php\' );

    // Check if our template was found, if not, bail
    if ( !$locate_template )
        return $template;

    return $locate_template;
});
