Question

我正在WordPress中构建自定义导航菜单，我有2级深度;父项和直接子项子项。有些物品是叶子。

我希望所有父项都没有url，以便我可以添加JS下拉功能。

下面的代码成功构建了我想要的菜单，但是，我需要识别当前页面，以便添加一个方便的CSS类，如.current-page或.current-parent-page。另外，如果我在子页面或项目上，我还需要识别当前父项和当前项目;就像我使用wp_nav_menu一样。我目前的代码是：

<?php
global $post;
$the_post_ID = $post->ID;

/*global $wp_query;
$page_object = $wp_query->get_queried_object();
$page_id     = $wp_query->get_queried_object_id();*/



if( ($locations =get_nav_menu_locations()) && isset($locations['primary']) ):
   $primary_nav_menu = wp_get_nav_menu_object( $locations['primary'] );
   $primary_nav_menu_items = wp_get_nav_menu_items( $primary_nav_menu->term_id, array( 'order' => 'DESC' ) ); ?>

<ul class="off-canvas-list site-menu-list">

  <?php foreach( (array) $primary_nav_menu_items as $nav_item ):

  /* get page id by using menu item object id */
  $nav_item_id = get_post_meta( $nav_item->ID, '_menu_item_object_id', true );

  /* set up a page object to retrieve page data */
  $page = get_page( $nav_item_id );
  $link = get_page_link( $nav_item_id );

  if( ! $nav_item->menu_item_parent ) {  /* this nav item has no parent */

    /* try to retrieve its child nav items */
    /* check function get_nav_menu_item_children() in functions.php */
    $child_nav_items = array();
    $child_nav_items = get_nav_menu_item_children( $nav_item->ID, $primary_nav_menu_items, false );

    if( empty( $child_nav_items ) ): /* nav item has no children - it is a leaf; it has a link url */?>
      <li class="????">
        <a href="<?php echo esc_url( $link ); ?>"><?php echo $nav_item->title; //$page->page_title; ?></a>
      </li>
    <?php else: // nav item has children nav items - construct a sub menu ?>
      <li class="has-submenu">
        <?php /* on mobile, it becomes a label button - do not include its url */?>
        <a href="#" class="ic-font"><?php echo $nav_item->title;//$page->post_title; ?></a>
        <ul class="sub-menu">
        <?php 
          foreach ( (array) $child_nav_items as $child_nav_item ): 
            // get page id from using menu item object id
            $child_nav_item_id = get_post_meta( $child_nav_item->ID, '_menu_item_object_id', true );

            // set up a page object to retrieve page data
            $child_nav_page = get_page( $child_nav_item_id );
            $child_nav_page_link = get_page_link( $child_nav_item_id );?>

            <li class="???">
              <a href="<?php echo esc_url( $child_nav_page_link ); ?>"><?php echo $child_nav_item->title; //$child_nav_page->post_title; ?></a>
            </li>
          <?php endforeach;?>
        </ul>
      </li>
    <?php endif; ?>

  <?php } /* this nav item has no parent */ ?>

<?php endforeach; /* loop through the primary_nav_menu_items */ ?>

</ul>

<?php endif; /* locations */ ?>

我尝试使用$nav_item->object_id并将其与当前的帖子ID进行比较但不起作用。我也尝试了is_page($nav_item->object_id)，但没有工作。

感谢您的帮助。
