WooCommerce产品按类别排序

Question

我有WooCommerce属性存档页面，我需要显示按类别排序的产品。像这样：

A类

• 产品X
• 产品Y
• 产品Z

B类

• 产品A
• 产品B
• 产品C

等

我现在的自定义循环的结果是：

A类

• 产品A
• 产品B
• 产品C
• 产品X
• 产品Y
• 产品Z

B类

• 产品A
• 产品B
• 产品C
• 产品X
• 产品Y
• 产品Z

等

因此它基本上显示了每个类别中属性术语中的所有产品，即使该产品甚至不在此类别中。我想我忽视了什么，但我无法弄清楚是什么？

<?php
/**

$taxonomy       = 'product_cat';
$orderby        = 'menu_order';
$order          = 'ASC';
$show_count     = 1; // 1 for yes, 0 for no
$pad_counts     = 0; // 1 for yes, 0 for no
$hierarchical   = 1; // 1 for yes, 0 for no

        $category_id    = $cat->term_id;
        $thumbnail_id   = get_term_meta( $cat->term_id, 'thumbnail_id', true );
        $image          = wp_get_attachment_url( $thumbnail_id );

        echo '<div id="' . $cat->slug . '" class="category ' . $cat->slug . '"><h2 class="category-title"><a href="'. esc_url( $term_link ) .'">'.$cat->name.'</a></h2>';

            $loop = new WP_Query( $args );

            while ( have_posts() ) : the_post();

                global $product;

                wc_get_template_part( 'content', 'product' );

            endwhile; // end of the loop. ?>

            </div><!-- end .category -->

            <?php

            wp_reset_query();

        endif;

    endforeach;

    wp_reset_query();

    ?>

Answer 1

为获取类别明智的产品添加以下代码

@Override
        protected void populateViewHolder(MovieViewHolder viewHolder, final Movie model, final int position) {
            if(tvNoMovies.getVisibility()== View.VISIBLE){
                tvNoMovies.setVisibility(View.GONE);
            }
            viewHolder.tvMovieName.setText(model.getMovieName());
            viewHolder.address.setText(model.getAddress());
            viewHolder.phone.setText(model.getPhone());
            viewHolder.lit.setText(model.getLit());
            viewHolder.lon.setText(model.getLon());
            Picasso.with(MainActivity.this).load(model.getMoviePoster()).into(viewHolder.ivMoviePoster);
         viewHolder.tvMovieName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MainActivity.this, DetailActivity.class);
             startActivity(intent);
        }
    });

        }

Answer 2

get_categories()和WP_Query()的参数不同。

明智地获取产品类别的论据。

$args_for_product = array(
            'tax_query' => array(array('taxonomy' =>$taxonomy,'field' => 'slug','terms' =>$cat->slug)),
            'orderby'       => $orderby,
            'order'         => $order,
);

使用tax_query传递产品查询中的类别。其他参数（如show_count,pad_counts,hierarchical,title_li,hide_empty未在WP_Query中传递）不需要。把上面的代码放在类别循环

中

还将while循环have_post()更改为$loop->have_post()，将the_post()更改为$loop->the_post()
