我在wordpress+woocommerce网站上有一个自定义菜单，使用Walker\\u Nav\\u菜单类。从站点隐藏帖子（产品）时，这些帖子和类别仍包含在自定义菜单中。我想知道如何从此菜单中删除特定的产品帖子，例如帖子ID=6927，或者如何从该菜单中删除类别（以及其中的产品），例如类别ID=41。我要隐藏的类别在此图像中为“范围结束”：
在过去的两天里，我尝试了许多解决方案，但都没有成功：
（1）
function wpse31748_exclude_menu_items( $items, $menu, $args ) {
// Iterate over the items to search and destroy
foreach ( $items as $key => $item ) {
if ( $item->object_id == 6927 ) unset( $items[$key] );
}
return $items;
}
add_filter( \'wp_get_nav_menu_items\', \'wpse31748_exclude_menu_items\', null, 3 );
以及上述的不同变体。
我不确定我是否完全偏离了轨道，但我想更新文件模板部件/模块/模块类别菜单。php排除该类别可能有效，以下是该文件的内容：
<?php
$orderby = \'date\';
$order = \'desc\';
$hide_empty = true ;
$cat_args = array(
\'orderby\' => $orderby,
\'order\' => $order,
\'hide_empty\' => $hide_empty,
);
$product_categories = get_terms( \'product_cat\', $cat_args );
if( !empty($product_categories)) :
?>
<div class="row">
<div class="col-12 sec-menu">
<ul class=" nav nav-justified" id="sec-menu">
<?php
foreach ($product_categories as $key => $category):
?>
<li class="nav-item">
<h2>
<a class="nav-link collapsed top-menu" href="#cat<?php echo $category->term_id; ?>" data-toggle="collapse" data-target="#cat<?php echo $category->term_id; ?>">
<?php echo $category->name; ?>
</a>
</h2>
<?php
$args = array(
\'posts_per_page\' => \'-1\',
\'post_type\' => \'product\',
\'post_status\' => \'publish\',
\'orderby\' => \'date\',
\'order\' => \'asc\',
\'tax_query\' => array(
array(
\'taxonomy\' => \'product_cat\',
\'terms\' => array($category->term_id),
\'operator\' => \'IN\'
),
)
);
$products = new WP_Query($args);
if($products->have_posts()):
?>
<div class="collapse sub-menu" id="cat<?php echo $category->term_id; ?>" aria-expanded="false" data-parent="#sec-menu">
<ul class="flex-column nav">
<?php
while($products->have_posts()):
$products->the_post();
?>
<li class="nav-item">
<a class="nav-link sub-link" href="<?php the_permalink();?>" title="<?php the_title(); ?>">
<span><?php the_title(); ?></span>
</a>
</li>
<?php
endwhile;
wp_reset_query();
?>
</ul>
</div>
<?php
endif;
?>
</li>
<?php
endforeach;
?>
</ul>
</div>
</div>
<?php
endif;
?>
非常感谢您的帮助。
EDIT这是函数中的Walker\\u Nav\\u菜单类。php文件：

$new_class = array();
$this->curItem = $item;
$indent = ($depth) ? str_repeat("\\t", $depth) : \'\';

$add_sub_class .= \' sub-link \';
}
$new_class = implode(\' \', $new_class);
// echo $new_class;
$class_names = join(\' \', apply_filters(\'nav_menu_css_class\', array_filter($classes), $item));

}
function start_lvl(&$output, $depth = 0, $args = array())
{
global $wp_query;
$thisItem = $this->curItem;
$indent = str_repeat("\\t", $depth);
$output .= "\\n$indent<div class=\'collapse\' id=\'submenu$thisItem->ID\' aria-expanded=\'false\'><ul id=\'submenu-$thisItem->ID\' class=\'flex-column nav sub-nav\'>\\n";
}
}
