php wp类型显示分类法

我正在使用wp类型插件管理wordpress站点上的自定义帖子类型。要显示帖子类型列表，我使用以下代码：

<?php 
        $args = array(
            'posts_per_page' => 20,
            'post_type' => 'products',
            'orderby' => 'meta_value',
            'post_count' => -1
        );
        $query = new WP_Query( $args ); ?>

        <?php while ( $query->have_posts() ) : $query->the_post(); $categories = get_the_category(); ?>

        <div>The custom post</div>



        <?php endwhile; wp_reset_postdata(); ?>

有没有方法可以修改它以显示（在本例中）产品的特定分类中的列表

干杯

如果可以的话，它看起来会像这样：

<?php 
    $args = array(
        'posts_per_page' => 20,
        'post_type' => 'products',
        'orderby' => 'meta_value',
        'post_count' => -1,
        'tax_query' => array(
            array(
                'taxonomy' => 'example', // get posts in the 'example' taxonomy
                'field' => 'slug', // that have a slug that matches
                'terms' => 'test', // any of the terms listed
            ),
        ),
    );
    $query = new WP_Query( $args ); ?>

    <?php while ( $query->have_posts() ) : $query->the_post(); $categories = get_the_category(); ?>

    <div>The custom post</div>



    <?php endwhile; wp_reset_postdata(); ?>

有关每个参数的详细信息，请查看WP_查询文档的。如果可以，它将如下所示：

<?php 
    $args = array(
        'posts_per_page' => 20,
        'post_type' => 'products',
        'orderby' => 'meta_value',
        'post_count' => -1,
        'tax_query' => array(
            array(
                'taxonomy' => 'example', // get posts in the 'example' taxonomy
                'field' => 'slug', // that have a slug that matches
                'terms' => 'test', // any of the terms listed
            ),
        ),
    );
    $query = new WP_Query( $args ); ?>

    <?php while ( $query->have_posts() ) : $query->the_post(); $categories = get_the_category(); ?>

    <div>The custom post</div>



    <?php endwhile; wp_reset_postdata(); ?>
