如何按类别woocommerce查询产品

Question

我正在Woocommerce建立快速订单/订单表

我想要的是这样的

Main category one
 Subcategory
        product
        product
 Subcategory
        product
        product

Main category two
 Subcategory
        product
        product
 Subcategory
        product
        product

我的问题是如何在正确的类别下查询产品

这就是我到目前为止所拥有的

<?php

        $custom = array(

                  'post_type' => 'product', 
                  'posts_per_page' => 100,

        ); 

        $cust_query = new WP_Query( $custom );

        if ( $cust_query->have_posts() ) :
            while( $cust_query->have_posts() ) : $cust_query->the_post(); 

            $cat = get_the_terms( get_the_ID(), 'product_cat' ); 


            ?>

        <a href="#" class="link"><?php echo $cat[0]->name; ?></a>
        <div><?php the_title();?></div>



    <?php   endwhile; 
        endif;  

这是一次查询每个类别我希望所有具有相同类别的产品都在正确的类别下，类别仅打印一次

尝试使用以下代码。 在这里，我假设您只有一个级别类别。

Main category one //level 0 
 Subcategory //level 1
    product
    product
Subcategory
    product
    product

Main category two //level 0 
Subcategory //level 1
    product
    product
Subcategory
    product
    product


<ul class="category-sidebar">

    $get_parent_cats = array(
        'parent' => '0', //get top level categories only
        'taxonomy'=>'product_cat',
        'hide_empty' => false
    ); 

    $all_categories = get_categories( $get_parent_cats );//get parent categories 
    foreach( $all_categories as $single_category ){
        //for each category, get the ID
        $catID = $single_category->cat_ID;

        echo '<li><a href=" ' . get_category_link( $catID ) . ' ">' . $single_category->name . '</a>'; //category name & link
        $get_children_cats = array(
            'child_of' => $catID, //get children of this parent using the catID variable from earlier
            'taxonomy'=>'product_cat',
            'hide_empty' => false
        );
        wp_reset_postdata();
        $child_cats = get_categories( $get_children_cats );//get children of parent category
