你可以用这种方法来做。

<小时>

$media_category = get_terms(\'media_category\');
foreach($media_category as $cat) {
    wp_reset_query();
    $args = array(\'post_type\' => \'your_post_type\',
        \'tax_query\' => array(
            array(
                \'taxonomy\' => \'media_category\',
                \'field\' => \'slug\',
                \'terms\' => $cat->slug,
            ),
        ),
     );
   $loop = new WP_Query($args);
     if($loop->have_posts()) {
      //  echo $cat->name;
        while($loop->have_posts()) : $loop->the_post();
            echo get_the_title();
        endwhile;
     }
} 

<?php
$args = array(
    \'post_type\' => \'product\',
    \'post_status\' => \'publish\',
    \'posts_per_page\' => -1,
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'taxonomy_name\',
            \'field\' => \'id\',
            \'terms\' => \'22\'
        )
    )
);
$the_query = new WP_Query( $args );
while ( $the_query->have_posts() ) : $the_query->the_post();
    //content
endwhile;
?>

您需要通过以下操作创建分类法归档：

1） 在主题目录中创建一个名为taxonomy-media_category.php 像这样的归档循环。。。

<?php
get_header(); ?>

<div id="container">
    <div id="content" role="main">

        <?php the_post(); ?>
        <h1 class="entry-title"><?php the_title(); ?></h1>

        <?php get_search_form(); ?>

        <h2>Archives by Month:</h2>
        <ul>
            <?php //SOME OF YOUR CODE HERE ?>
        </ul>

    </div><!-- #content -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>

最后我用了这个：

$taxonomy = \'MY_TAXONOMY_HERE\';

// Get all the terms of that taxonomy
$terms = get_terms( $taxonomy, \'orderby=count&hide_empty=1\' );

$args = array_merge( $args, [
    \'tax_query\' => array(
        array(
            \'taxonomy\' => $taxonomy,
            \'field\' => \'id\',
            \'terms\' => wp_list_pluck( $terms, \'term_id\' )
        )
    )
]);

$query = new WP_Query( $args );
