WooCommerce印刷子产品类别

我正在Woocommerce中使用Wordpress，我在产品内容产品单的详细页面上。php。

我创建了几个“sub”，只需打印与该产品关联的子类别。

我正在使用此代码：

$categories = array (
        \'type\' => \'product\',
        \'child_of\' => 1,
        \'parent\' => \'8\',
        \'orderby\' => \'term_group\',
        \'hide_empty\' => true,
        \'hierarchical\' = > 1,
        \'exclude\' => \'\',
        \'property\' => \'\',
        \'number\' => \'\',
        \'taxonomy\' => \'product_cat\',
        \'pad_counts\' => false);

$cats = get_categories ($categories);
foreach ($cats as $cat) {
    echo \'<a <br/> href="\'. get_term_link($cat-> slug,\' product_cat \').\' "> \'. $cat-> name.\'</a>\';
}

其中“parent”=>“8”是“我的类别父亲的id”

但此代码打印的所有子类别都不是空的，我只对这些子类别感兴趣，而不是本产品。

谢谢，祝你好运

/* This is product id */ $product_id = 1; /* This is the id of the parent category */ $parent_category_id = 8; $cats = get_categories ( array ( \'type\' => \'product\', \'parent\' => $parent_category_id, \'orderby\' => \'term_group\', \'hide_empty\' => true, \'hierarchical\' = > 1, \'exclude\' => \'\', \'property\' => \'\', \'number\' => \'\', \'taxonomy\' => \'product_cat\', \'pad_counts\' => false )); $non_empty_sub_categories_ids = array_map(create_function(\'$cat\', \'return $cat->term_id;\'), $cats); $product_cats = get_the_terms( $product_id, \'product_cat\' ); foreach ($product_cats as $product_cat) { if(in_array($product_cat->term_id, $non_empty_sub_categories_ids)) { echo \'<a <br/> href="\'. get_term_link($product_cat->slug,\' product_cat \').\' "> \'. $product_cat->name.\'</a>\'; } }

<?php $args = array( \'taxonomy\' => \'product_cat\', \'slug\' => array(\'category_slug\'), \'hide_empty\' => true ); $product_cat = get_terms( $args ); foreach ($product_cat as $parent_product_cat){ echo \'<ul> <li><a href="\'.get_term_link($parent_product_cat->term_id).\'">\'.$parent_product_cat->name.\'</a> <ul> \'; $child_args = array( \'taxonomy\' => \'product_cat\', \'hide_empty\' => true, \'parent\' => $parent_product_cat->term_id ); $child_product_cats = get_terms( $child_args ); foreach ($child_product_cats as $child_product_cat) { echo \'<li><a href="\'.get_term_link($child_product_cat->term_id).\'">\'.$child_product_cat->name.\'</a></li>\'; } echo \' </ul> </li> </ul>\'; }
