WP_LIST_Pages()，但仅显示您所在分支上的子项

假设我有这个菜单：

Top
    |___    Sub 1
            |___    Sub Sub 1
            |___    Sub Sub 2
            |___    Sub Sub 3
            |___    Sub Sub 4
    |___    Sub 2
            |___    Sub Sub 1
            |___    Sub Sub 2
            |___    Sub Sub 3
            |___    Sub Sub 4
    |___    Sub 3
            |___    Sub Sub 1
            |___    Sub Sub 2
            |___    Sub Sub 3
            |___    Sub Sub 4
    |___    Sub 4
            |___    Sub Sub 1
            |___    Sub Sub 2
            |___    Sub Sub 3
            |___    Sub Sub 4

我可以使用以下命令列出该菜单：

    if( 0 == $post->post_parent && 0 == count( $children ) )
        return;

    if( 0 == $post->post_parent )
    {
        $child_of = $post->ID;
    }
    else {
        $parents = get_post_ancestors( $post->ID );
        $child_of = end( $parents );
    }

    $args = array
    (
        \'child_of\' => $child_of,
        \'echo\' => 0,
        \'title_li\' => \'\'
    );

    $pages = wp_list_pages( $args );

这很好，但我不想显示所有页面项目。我想要的是，只显示您所在页面的imediate子项。

所以如果我在第页Top 菜单应如下所示：

Top
    |___    Sub 1
    |___    Sub 2
    |___    Sub 3
    |___    Sub 4

如果我在第页Top/Sub 3 菜单应如下所示：

Top
    |___    Sub 1
    |___    Sub 2
    |___    Sub 3
            |___    Sub Sub 1
            |___    Sub Sub 2
            |___    Sub Sub 3
            |___    Sub Sub 4
    |___    Sub 4

等等，这样它就可以工作到任何深度。

Rarst提出了一个nice answer 但这是在使用WordPress菜单时使用的。我正在为wp\\u list\\u pages（）寻找相同的内容。寻找使用助行器或过滤器/挂钩的答案。我知道如何用CSS解决这个问题，但这并不能解决将不必要的HTML发送到浏览器的问题。

$parents = array( $post->ID ); if( 0 != $post->post_parent ) { $parents = array_merge( $parents, get_post_ancestors( $post->ID ) ); } $child_of = end( $parents ); $args = array ( \'child_of\' => $child_of, \'echo\' => 0, \'title_li\' => \'\', \'walker\' => new chg_Sub_Page_Navigation_Walker( $parents ) ); $pages = wp_list_pages( $args );

class chg_Sub_Page_Navigation_Walker extends Walker_Page { var $parents = array(); function __construct( $parents ) { $this->parents = $parents; } function start_el( &$output, $page, $depth, $args, $current_page ) { if( in_array( $page->post_parent, $this->parents ) ) parent::start_el( &$output, $page, $depth, $args, $current_page ); } function end_el( &$output, $page, $depth ) { if( in_array( $page->post_parent, $this->parents ) ) parent::end_el( &$output, $page, $depth ); } }

global $post; $pages =& get_children(array( \'post_type\' => \'page\', \'post_parent\' => $post->ID, )); $siblings = get_children(array( \'post_type\' => \'page\', \'post_parent\' => $post->post_parent, )); $ancestors = get_post_ancestors($post->ID);

<ul> <?php global $post; $children =& get_children(array( \'post_type\' => \'page\', \'post_parent\' => $post->ID, )); $siblings = get_children(array( \'post_type\' => \'page\', \'post_parent\' => $post->post_parent, )); $ancestors = get_post_ancestors($post->ID); if(!empty($ancestors)): $ancestors = array_reverse($ancestors); foreach($ancestors as $aid): $p = get_post($aid); ?> <li> <?php echo $p->post_title ?> <ul> <?php endforeach?> <?php if(!empty($siblings)): ?> <?php foreach($siblings as $sibling): ?> <li> <?php echo $sibling->post_title?> <?php if($sibling->ID == $post->ID && !empty($children)): ?> <ul> <?php foreach($children as $child): ?> <li><?php echo $child->ID ?></li> <?php endforeach?> </ul> <?php endif ?> </li> <?php endforeach ?> <?php endif ?> <?php foreach ($ancestors as $aid):?> </ul></li> <?php endforeach ?> <?php endif ?> </ul>

WooCommerce dynamic menus

我有一个基本的WordPress网站，设置了Suffusion主题和WooCommerce插件。这在大多数情况下都很有效，但是当我让人们点击/悬停在“Shop”菜单图标上时，我希望它能够动态地下拉我定义的产品类别。我如何做到这一点？我肯定有关于这个主题的文档，但我不确定要查找什么。我主要是一名系统管理员。
