获取WooCommerce子分类产品

Question

我正在尝试在主分类下显示带有产品的woocommerce子分类。

<ul class="wsubcategs">
<?php
$wsubargs = array(
'hierarchical' => 1,
'show_option_none' => '',
'hide_empty' => 0,
'parent' => $category->term_id,
'taxonomy' => 'product_cat'
);
$wsubcats = get_categories($wsubargs);
foreach ($wsubcats as $wsc):
?>
<li><a href="<?php echo get_term_link( $wsc->slug, $wsc->taxonomy );?>"><?php echo $wsc->name;?></a>

</li>
<?php
endforeach;
?>

</ul>

到目前为止，我已经按照正确的主分类得到了正确的子分类，但是它们下面没有显示任何产品。如有建议，请告知。 O.

Answer 1

有许多方法可以在WordPress中实现这一点。您可以使用WP_Query对象执行自定义查询以获取该类别中的所有产品，这可能是最灵活的选项，但有更简单的方法。 WooCommerce提供了专门用于显示特定类别商品的短代码。输出将使用已内置在WooCommerce中的模板。

<?php echo do_shortcode('[product_category category="appliances"]');?>

这将为您提供特定类别下的产品。 在您的代码中，您可能会这样做：

<ul class="wsubcategs">
<?php
$wsubargs = array(
    'hierarchical' => 1,
    'show_option_none' => '',
    'hide_empty' => 0,
    'parent' => $category->term_id,
    'taxonomy' => 'product_cat'
);
$wsubcats = get_categories($wsubargs);
foreach ($wsubcats as $wsc):
?>
    <li>
        <a href="<?php echo get_term_link( $wsc->slug, $wsc->taxonomy );?>"><?php echo $wsc->name;?></a>
        <div class="products">
            <?php echo do_shortcode('[product_category category="'.$wsc->slug.'"]');?>
        </div>
    </li>
<?php endforeach;?>
</ul>

我注意到你的问题中有一个列表输出。我认为你可能不希望实际上在每个类别下面输出产品（详细模板），而是更倾向于显示子列表中的产品数量或产品标题。 以下是如何显示产品数量： 您可以在上述foreach循环的任何位置使用此代码。 以下是如何在每个类别的列表元素中显示产品标题子列表：

<?php $subcategory_products = new WP_Query( array( 'post_type' => 'product', 'product_cat' => $wsc->slug ) );
    if($subcategory_products->have_posts()):?>
    <ul class="subcat-products">
        <?php while ( $subcategory_products->have_posts() ) : $subcategory_products->the_post(); ?>
        <li>
            <a href="<?php echo get_permalink( $subcategory_products->post->ID ) ?>">
                <?php the_title(); ?>
            </a>
        </li>
        <?php endwhile;?>
    </ul>
<?php endif; wp_reset_query(); // Remember to reset ?>

以下是如何在您的代码中实现此功能：

这是在您上面的代码中实现此功能的方式：

<ul class="wsubcategs">
<?php
$wsubargs = array(
    'hierarchical' => 1,
    'show_option_none' => '',
    'hide_empty' => 0,
    'parent' => $category->term_id,
    'taxonomy' => 'product_cat'
);
$wsubcats = get_categories($wsubargs);
foreach ($wsubcats as $wsc):
?>
    <li>
        <a href="<?php echo get_term_link( $wsc->slug, $wsc->taxonomy );?>"><?php echo $wsc->name;?></a>
        <?php $subcategory_products = new WP_Query( array( 'post_type' => 'product', 'product_cat' => $wsc->slug ) );
            if($subcategory_products->have_posts()):?>
        <ul class="subcat-products">
            <?php while ( $subcategory_products->have_posts() ) : $subcategory_products->the_post(); ?>
            <li>
                <a href="<?php echo get_permalink( $subcategory_products->post->ID ) ?>">
                    <?php the_title(); ?>
                </a>
            </li>
            <?php endwhile;?>
        </ul>
    <?php endif; wp_reset_query(); // Remember to reset ?>
    </li>
<?php endforeach;?>
</ul>
