有没有一种方法可以将Twitter引导与页面层次结构/wp_list_pages一起使用

感谢您的添加-这给了它一些上下文。

您需要在代码中添加以下内容：

<nav class="navbar navbar-default">
<div class="container-fluid">
    <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
    </div>
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav">
            <?php //this will be where you add your statement if we're on a parent/child page
            wp_list_pages(array(
                'title_li' => '',
                'child_of' => $post->ID,
                'walker' => new BS_Page_Walker(),
            ));
            ?>
        </ul>
    </div>
</div>

然后你会想把这个助行器添加到你的函数文件中，或者添加到你主题中的某个地方。

    class BS_Page_Walker extends Walker_Page {
    public function start_lvl( &$output, $depth = 0, $args = array() ) {
        $indent = str_repeat("'t", $depth);
        $output .= "'n$indent<ul class='dropdown-menu' role='menu'>'n";
    }
    public function start_el( &$output, $page, $depth = 0, $args = array(), $current_page = 0 ) {
        if ( $depth ) {
            $indent = str_repeat( "'t", $depth );
        } else {
            $indent = '';
        }
        $css_class = array( 'page_item', 'page-item-' . $page->ID );
        if ( isset( $args['pages_with_children'][ $page->ID ] ) ) {
            $css_class[] = 'page_item_has_children';
        }
        if ( ! empty( $current_page ) ) {
            $_current_page = get_post( $current_page );
            if ( in_array( $page->ID, $_current_page->ancestors ) ) {
                $css_class[] = 'current_page_ancestor';
            }
            if ( $page->ID == $current_page ) {
                $css_class[] = 'current_page_item';
            } elseif ( $_current_page && $page->ID == $_current_page->post_parent ) {
                $css_class[] = 'current_page_parent';
            }
        } elseif ( $page->ID == get_option('page_for_posts') ) {
            $css_class[] = 'current_page_parent';
        }
        /**

        $css_classes = implode( ' ', apply_filters( 'page_css_class', $css_class, $page, $depth, $args, $current_page ) );
        if ( '' === $page->post_title ) {

            $output .= ' ' . mysql2date( $date_format, $time );
        }
    }
}

好消息，wp_list_pages有一个Walker，您可以设置它，并在新的Walker中应用所需的引导程序类。
