Wordpress：将活动类添加到$ parent_title [英] Wordpress: Add active class to $parent_title

问题描述

我正在显示侧栏菜单，其中列出了父页面和子页面。

I am displaying a sidebar menu listing Parent and child pages.

• 父母


• 第一页


• 第二页


• 第三页

• Parent
• Child page one
• Child page two
• Child page three

我的代码将类.current_page_item应用于活动子页面，但不应用于活动父页面。我希望父级在该页面上也有类.current_page_item。

My code is applying the class .current_page_item to the active child pages, but not to the active parent page. I would like the parent to have the class .current_page_item too when on that page.

<?php
if($post->post_parent)
    $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
else
    $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
if ($children) {
    $parent_title = get_the_title($post->post_parent);?>
    <ul id="sub">
        <li><a href="<?php echo get_permalink($post->post_parent) ?>"><?php echo $parent_title;?></a></li>
        <?php echo $children; ?>
    </ul>
<?php } ?>

以下是输出内容的概念：

Here is an idea of what is being outputted:

<ul id="sub">
    <li><a href="#">Parent</a></li>
    <li class="page_item page-item-19 current_page_item"><a href="#">Child page</a></li>
    <li class="page_item page-item-21"><a href="#">Child page</a></li>
    <li class="page_item page-item-23"><a href="#">Child page</a></li>
</ul>

推荐答案

您应该使用 get_pages <或 wp_get_nav_menu_items 。任何返回一个post对象数组的WordPress函数。

You should use get_pages or wp_get_nav_menu_items. Any WordPress function that returns an array of post objects.

$children = wp_get_nav_menu_items( 'Main Menu' ); // dump to make sure this is an array of objects
echo "<ul id='sub'>";
foreach($children as $item) {
    $class = '';
    if ( $item->object_id == $post->post_parent ){
        $class = 'current_page_ancestor';
    } else if ( $item->object_id == $post->ID ){
        $class = 'current_page_item';
    }
    echo "<li " . $class . "><a href='" . $item->url . "'>" . $item->title . "</a></li>";
}
echo "</ul>";

这将获取一个WordPress帖子数组，然后循环遍历它们。

This gets an array of WordPress posts, then loops through them.

如果当前迭代中的帖子ID与您正在查看的帖子的父主题相同，请添加类'current_page_ancestor。'

If the post ID in the current iteration is the same as the parent of the post you are viewing, add the class 'current_page_ancestor.'

如果当前迭代中的帖子ID与您正在查看的帖子相同，请添加类'current_page_item。'

If the post ID in the current iteration is the same as the post you are viewing, add the class 'current_page_item.'
