我在category部分创建了一个字段，它是category color
Codes are in different lines in file so I will paste them separately
$kategoriler_self = get_categories(array( \'hide_empty\' => false ));
foreach ($kategoriler_self as $kategori){
$this->kategoriler[$kategori->cat_ID] = $kategori->cat_name;
*
$kategoriid = $kategori;
$catquery = new WP_Query( \'cat=\' .$kategoriid. \'&posts_per_page=1\' );
while($catquery->have_posts()) : $catquery->the_post();
*
/* Cat Color Option */
$color = get_term_meta( $kategoriid, \'_category_color\', true );
$color = ( ! empty( $color ) ) ? "#{$color}" : \'#000\';
我用这个代码显示我的类别颜色
<?php echo $color; ?>
So, I want to do same thing for my menu.这是我的菜单代码。
<?php wp_nav_menu(array(\'theme_location\' => \'sidebar-kategori\', \'container\' => \'false\', \'items_wrap\' => \'<ul>%3$s</ul>\')); ?>
How can I show category color for every li in menu ?
感谢您的阅读！
UPDATE:
我找到了一篇关于我的问题的好文章，我想与大家分享。

你可以add_filter() 这个wp_nav_menu_items() 钩它允许访问列表项的html输出$items.
紧接着这个钩子wp_nav_menu_{$menu->slug}_items() 钩子，使您可以访问相同但特定的菜单。
Info on add-filter() if you need it.
两个
wp_nav_menu_items 上下文中的相关挂钩：
They are at lines 220 and 231 of wp-includes/nav-menu-template.php来自trac：
