如何在城市页面下显示那些服务显示那些城市服务提供商提供的

Question

我创建了一个列表网站，我在其中使用服务提供商作为自定义帖子类型，将城市和服务用作自定义分类类型，例如类别。现在，我想在城市页面下显示那些服务，将显示哪些服务提供那些城市服务提供商。

$args = array(
                'taxonomy' => 'service',
                'parent'        => 0, 
                'orderby'       => 'name',
                'order'         => 'ASC',
                'hierarchical'  => 1,
                'hide_empty'    => 0,
                'pad_counts'    =>0
            );

            $categories = get_categories( $args );

            foreach ( $categories as $category ){

                echo '<div class="packer-movers">
      <div class="container">
        <div class="row">';                

                echo '<h2>' . $category->name . '</h2>';
            $cityargs = array(
                    'taxonomy' => 'city',
                    'parent'        => term_id, 
                    'orderby'       => 'name',
                    'order'         => 'ASC',
                    'hierarchical'  => 1,
                    'hide_empty'    => 0,
                    'pad_counts'    => 0
                );
                $sub_args = array(
                    'taxonomy' => 'service',
                    'parent'        => $category->term_id, 
                    'orderby'       => 'name',
                    'order'         => 'ASC',
                    'hierarchical'  => 1,
                    'hide_empty'    => 0,
                    'pad_counts'    => 0
                );

                $sub_categories = get_categories( $sub_args );
                echo "<div class='children'>";  

                foreach ( $sub_categories as $sub_category ){
                    echo '<div class="col-sm-3">
                <div class="mvrs">
                    <div class="mvrs-img">';
                     if (function_exists('get_wp_term_image'))
                    {
                        $meta_image = get_wp_term_image($sub_category->term_id); 
                    }                         

                    echo "<img src='$meta_image' class='img-responsive hvr-grow' alt='. $sub_category->name . '>";                        
                    echo '<div class="movrs">
                    <div class="row">
                    <p class="mvrs-hd">'. $sub_category->name . '</p>
                    <div class="mvrs-btn">
                    <button class="get-qut">GET QUOTES</button>
                    </div>
                    </div>
                    </div>';
                    //echo '<span>'. $sub_category->name . '</span>';
                    echo "</div>
      </div>
      </div>";    
                }
                echo "</div>";
                echo "</div></div></div>";    
            }

给我一​​些参考。
