Wordpress 如何在wp_查询中添加分类作为参数

这是显示产品列表的程序的一部分。我将产品创建为自定义帖子，需要根据分类法显示帖子

谁可以在选择后参数中提供分类作为参数

我使用工具集插件创建了分类法和帖子

   <?php $taxonomies = get_terms([
    'taxonomy' => 'product_category',
    'parent' => 0,
    'orderby' => 'name',
    'order' => get_query_var('Order', 'ASC'),
    'hide_empty' => false,
]);
?><?php 
$i=1;
if  ($taxonomies) {
  foreach ($taxonomies  as $taxonomy ) {; ?>
<?php
   if(!empty(do_shortcode('[types term_id="'.$taxonomy->term_id.'" termmeta="secondary-category-image" size="product-main-cat" url="true"][/types]'))){
    $pro_cat_img = do_shortcode('[types term_id="'.$taxonomy->term_id.'" termmeta="secondary-category-image" size="product-main-cat" url="true"][/types]');
   }else{
    $pro_cat_img = get_template_directory_uri()."/img/product-guitar.png";
   } ?>

                        <h1>
                          <?php echo $taxonomy->name; 
//$ir=$taxonomy->name;
                          ?>
                        </h1>

                        <ul>

<?php 
            // args
            $args = array(
               'posts_per_page'  => 5,
               'post_type'    => 'product',
               'post_status'  => 'publish',
               //how can i add taxonomies asan argument here
            );
            // query            
            $the_query = new WP_Query( $args );
            $count = $the_query->post_count; 
            if( $the_query->have_posts() ):
             while( $the_query->have_posts() ) : $the_query->the_post(); 
          if(has_post_thumbnail(get_the_ID())) {                              
            $feature_image_full = simplexml_load_string(get_the_post_thumbnail(get_the_ID(), 'banner_img'));   
            $pr_img_source = $feature_image_full->attributes()->src;

                           ?>
                           <li>
                              <span>
                              <?php echo the_title(); ?>
                              </span>
                           </li>


          <?php } endwhile;  endif; wp_reset_query(); ?>

                        </ul>

attributes（）->src；
?>

这是工作代码

最好知道您查看了哪些资源，具体尝试了哪些资源，以及分类法的名称（键，而不是标签）。你看过这个吗：或者读过这个：？如果是，您是否尝试添加参数？您尝试添加了哪些参数？当你添加它们的时候发生了什么？谢谢你，它起了作用，这真的很重要，我也在添加结果，以供将来其他人参考
