我有wordpress菜单：

<?php
    wp_nav_menu( array(
    \'theme_location\' => \'menu-categorias\',
    \'container\' => \'ul\',
    \'menu_class\' => \'navbar-nav dragscroll\' ) );
?>

其输出：

<ul id="menu-menu-categorias" class="navbar-nav dragscroll">
  <li id="menu-item-8" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-8 nav-item fadeIn">
    <a href="http://website.test/category/ux/" class="nav-link">Ux</a>
  </li>
  <li id="menu-item-9" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-9 nav-item fadeIn">
    <a href="http://website.test/category/editorial/" class="nav-link">Editorial</a>
  </li>
</ul>

我想要nav-items 替换为# 并将类别的名称（小写）添加到li 班因此，菜单输出应如下所示：

<ul id="menu-menu-categorias" class="navbar-nav dragscroll">
  <li id="menu-item-8" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-8 nav-item fadeIn ux">
    <a href="#ux" class="nav-link">Ux</a>
  </li>
  <li id="menu-item-9" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-9 nav-item fadeIn editorial">
    <a href="#ux" class="nav-link">Editorial</a>
  </li>
</ul>

我尝试添加此内容，但没有任何更改：

function lb_menu_anchors($items, $args) {
  foreach ($items as $key => $item) {
      if ($item->object == \'custom\' && substr($item->url, 0, 1) == \'#\') {
          $item->url = site_url() . $item->url;
      }
  }
  return $items;
}
add_filter(\'wp_nav_menu_objects\', \'lb_menu_anchors\', 10, 2);

实现这两件事有什么帮助吗？

add_filter( \'nav_menu_link_attributes\', function ( $atts, $item, $args ) {
    if ( \'menu-categorias\' === $args->theme_location && \'category\' === $item->object ) {
         $atts[\'href\'] = \'#\' . get_term_field( \'slug\', $item->object_id );
    }

    return $atts;
}, 10, 3 );

add_filter( \'nav_menu_css_class\', function ( $classes, $item, $args ) {
    if ( \'menu-categorias\' === $args->theme_location && \'category\' === $item->object ) {
         $classes[] = get_term_field( \'slug\', $item->object_id );
    }

    return $classes;
}, 10, 3 );
