我需要展示
每当我点击子项时，主项第一子项第二子项。我的意思是，我不想显示其他主要术语，只想显示我与子术语一起选择的术语。
在里面woocommerce-template.php 我使用：
function woocommerce_content() {
if ( is_singular( \'product\' ) ) {
while ( have_posts() ) : the_post();?>
<div class="three columns alpha">
<div id="menu_commerce">
<?php
global $post;
$terms = get_the_terms( $post->ID, \'product_cat\' );
foreach ( $terms as $term ){
$category_id = $term->term_id;
$category_name = $term->name;
$category_slug = $term->slug;
echo \'<li><a href="\'. get_term_link($term->slug, \'product_cat\') .\'">\'.$category_name.\'</a></li>\';
}?>
</div><!--END MENU COMMERCE-->
</div><!--END 3 COLUMNS ALPHA-->
<div class="thirteen columns alpha">
<?php woocommerce_get_template_part( \'content\', \'single-product\' );?>
</div>
<?php endwhile;
} else {
?>
<div class="three columns alpha">
<div id="menu_commerce">
<?php
global $wp_query;
// get the query object
$cat_obj = $wp_query->get_queried_object();
if($cat_obj) {
$category_name = $cat_obj->name;
$category_desc = $cat_obj->description;
$category_ID = $cat_obj->term_id;
$category_slug = $cat_obj->slug;
}
woocommerce_subcats_from_parentcat_by_ID($category_ID)
?>
</div><!--END MENU COMMERCE-->
</div><!--END 3 COLUMNS ALPHA-->
<div class="thirteen columns alpha">
<div id="prod_titolo"><h1><?php woocommerce_page_title(); ?></h1></div>
<hr style="margin-bottom:20px"/>
<?php do_action( \'woocommerce_archive_description\' ); ?>
<?php if ( have_posts() ) : ?>
<?php do_action(\'woocommerce_before_shop_loop\'); ?>
<div id="menu_grid">
<?php woocommerce_product_loop_start(); ?>
<?php woocommerce_product_subcategories(); ?>
<?php while ( have_posts() ) : the_post(); ?>
<div class="four columns">
<?php woocommerce_get_template_part( \'content\', \'product\' ); ?>
</div><!--END 4 col-->
<?php endwhile; // end of the loop. ?>
<?php woocommerce_product_loop_end(); ?>
</div><!--END menu grid-->
它适用于单个产品，但如果我单击子项，主项将消失。
我在中使用的函数functions.php 是：
function woocommerce_subcats_from_parentcat_by_ID($parent_cat_ID) {
$args = array(
\'hierarchical\' => 1,
\'show_option_none\' => \'\',
\'hide_empty\' => 0,
\'parent\' => $parent_cat_ID,
\'taxonomy\' => \'product_cat\'
);
$subcats = get_categories($args);
echo \'<ul class="wooc_sclist">\';
foreach ($subcats as $sc) {
$link = get_term_link( $sc->slug, $sc->taxonomy );
echo \'<li><a href="\'. $link .\'">\'.$sc->name.\'</a></li>\';
}
echo \'</ul>\';
}
你能帮帮我吗？

代码
function wc_origin_trail_ancestor( $link = false, $trail = false ) {
if (is_product_category()) {
global $wp_query;
$q_obj = $wp_query->get_queried_object();
$cat_id = $q_obj->term_id;
$descendant = get_term_by("id", $cat_id, "product_cat");
$descendant_id = $descendant->term_id;
$ancestors = get_ancestors($cat_id, \'product_cat\');
$ancestors = array_reverse($ancestors);
$origin_ancestor = get_term_by("id", $ancestors[0], "product_cat");
$origin_ancestor_id = $origin_ancestor->term_id;
$ac = count($ancestors);
} else if ( is_product() ) {
$ancestors = get_the_terms( $post->ID, \'product_cat\' );
$i = 0;
foreach($ancestors as $ancestor) {
if( $i == 0 ) {
$origin_ancestor = $ancestor;
$origin_ancestor_id = $origin_ancestor->term_id;
}
}
$ancestors = array_reverse($ancestors);
$ac = count($ancestors);
$descendant = $ancestors[0];
$descendant_id = $descendant->term_id;
$ancestors = array_reverse(get_ancestors($descendant_id, \'product_cat\'));
}
$c = 1;
if( $trail == false ){
$origin_ancestor_term = get_term_by("id", $origin_ancestor_id, "product_cat");
$origin_ancestor_link = get_term_link( $origin_ancestor_term->slug, $origin_ancestor_term->taxonomy );
if($link == true)
echo \'<a href="\'. $origin_ancestor_link .\'">\';
echo $origin_ancestor->name;
if($link == true)
echo \'</a>\';
}else{
foreach ($ancestors as $ancestor) {
$ancestor_term = get_term_by("id", $ancestor, "product_cat");
$ancestor_link = get_term_link( $ancestor_term->slug, $ancestor_term->taxonomy );
if($c++ == 1)
echo \'» \';
else if($c++ != 1 || $c++ != $ac)
echo \' » \';
if($link == true)
echo \'<a href="\'. $ancestor_link .\'">\';
echo $ancestor_term->name;
if($link == true)
echo \'</a>\';
}
$descendant_term = get_term_by("id", $descendant_id, "product_cat");
$descendant_link = get_term_link( $descendant_term->slug, $descendant_term->taxonomy );
echo \' » \';
if($link == true)
echo \'<a href="\'. $descendant_link .\'">\';
echo $descendant->name;
if($link == true)
echo \'</a>\';
}
}
如何使用顶级，起源祖先；无链接
wc_origin_trail_ancestor();wc_origin_trail_ancestor(true);wc_origin_trail_ancestor(false,true);wc_origin_trail_ancestor(true,true);
