我希望展示属于特定菜单的特定菜肴。
如何在循环中创建条件语法以搜索该菜单类型并循环属于该菜单类型的帖子？
function custom_post_type_food_dish()
{

模板中的HTML / PHP部分：
<div class="container-fluid">
<?php
$args = array(
'post_type' => 'food_dish',
'taxonomy_name' => 'menu'
);
$loop = new WP_Query($args);
while ($loop->have_posts()) : $loop->the_post();
//prePrint($loop);
if ( in_category( 'premium' ) ) {
?>
<a href="<?php the_permalink() ?>">
<div class="row">
<div class="col-md-3">
<?php the_post_thumbnail('medium', array('class' => 'img-responsive')); ?>
</div>
<div class="col-md-6">
<p><?php the_excerpt() ?></p>
</div>
<div class="col-md-3">
<h3><?php the_title(); ?></h3>
</div>
</div>
</a>
<?php
}
endwhile; ?>
</div>
