woocommerce - How do I get the most top level category of the current product category
提问by Gman
I have a Woocommerce product and I need to display on that page the Most top level category of a category assigned to the product
我有一个 Woocommerce 产品，我需要在该页面上显示分配给该产品的类别的最高级别类别
- Main Product Category
-- Sub Product Category
--- Category Assigned to product
I need to get the ID or name of "Main Product Category" so that I can display it in the single product category.
我需要获取“Main Product Category”的ID或名称，以便我可以在单个产品类别中显示它。
I already tried doing the following:
我已经尝试执行以下操作：
global $post;
$terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($terms as $term) {
$product_cat_id = $term->term_id;
$thetop_parent = woocommerce_get_term_top_most_parent( $product_cat_id , 'product_cat' );
echo $thetop_parent;
}
But It didn't worked at all and it brakes the page from loading after woocomerce_get_term... I'm not sure what to do at this point It
但它根本不起作用，它在 woocomerce_get_term 之后阻止页面加载......我不知道此时该怎么做它
thanks for any help on this.
感谢您对此的任何帮助。

After a lot of research I figured a way to solve this. I hope this will help someone.
经过大量研究，我找到了解决此问题的方法。我希望这会帮助某人。
solution:
解决方案：
global $post;
$prod_terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($prod_terms as $prod_term) {
// gets product cat id
$product_cat_id = $prod_term->term_id;
// gets an array of all parent category levels
$product_parent_categories_all_hierachy = get_ancestors( $product_cat_id, 'product_cat' );
// This cuts the array and extracts the last set in the array
$last_parent_cat = array_slice($product_parent_categories_all_hierachy, -1, 1, true);
foreach($last_parent_cat as $last_parent_cat_value){
// $last_parent_cat_value is the id of the most top level category, can be use whichever one like
echo '<strong>' . $last_parent_cat_value . '</strong>';
}
}

or maybe this:
或者这个：
$cat = get_the_terms( $product->ID, 'product_cat' );
foreach ($cat as $categoria) {
if($categoria->parent == 0){
echo $categoria->name;
}
}

I know this is an old post, but I had a similar situation where we needed to get the root category of the current product being viewed. The simplest solution I could think of was to look at how WooCommerce does its breadcrumbs, and this piece of code is what did the trick for me:
我知道这是一篇旧帖子，但我遇到了类似的情况，我们需要获取当前正在查看的产品的根类别。我能想到的最简单的解决方案是看看 WooCommerce 是如何做面包屑的，这段代码对我有用：
if ( is_product() ) {
global $post;
$terms = wc_get_product_terms( $post->ID, 'product_cat', array( 'orderby' => 'parent', 'order' => 'DESC' ) );
if ( ! empty( $terms ) ) {
$main_term = $terms[0];
$ancestors = get_ancestors( $main_term->term_id, 'product_cat' );
if ( ! empty( $ancestors ) ) {
$ancestors = array_reverse( $ancestors );
// first element in $ancestors has the root category ID
// get root category object
$root_cat = get_term( $ancestors[0], 'product_cat' );
}
else {
// root category would be $main_term if no ancestors exist
}
}
else {
// no category assigned to the product
}
}

Here the solution i actually use
这是我实际使用的解决方案
function get_parent_terms($term) {
if ($term->parent > 0){
$term = get_term_by("id", $term->parent, "product_cat");
return get_parent_terms($term);
}else{
return $term->term_id;
}
}
global $wp_query;
$cat_obj = $wp_query->get_queried_object();
$Root_Cat_ID = get_parent_terms($cat_obj);

This is the function I've developed to use.
这是我开发使用的功能。
/**
* Get product's top category
* @param int $pid. The product ID
*
* @return int. Returns product categories parent ID
*/
function get_product_top_category($pid) {
global $wpdb;
$cat_id = $wpdb->get_var('SELECT b.term_id FROM '.$wpdb->prefix.'term_relationships a, '.$wpdb->prefix.'term_taxonomy b WHERE a.object_id = "'.$pid.'" AND a.term_taxonomy_id = b.term_taxonomy_id AND b.parent = "0" AND b.taxonomy = "product_cat" LIMIT 1');
return $cat_id;
}
So you can fetch the top category of current product by using this
因此，您可以使用此获取当前产品的顶级类别
$top_level_term = get_product_top_category($post->ID);
A limitation of this code are that it could return multiple top level categories of any product. To combat that, I used LIMIT 1to return only single category which suits fine for me.
此代码的一个限制是它可以返回任何产品的多个顶级类别。为了解决这个问题，我过去LIMIT 1只返回适合我的单个类别。

Here if u have the a "category_ID"
在这里，如果你有一个“category_ID”
/*If you dont have a category ID use this:
* $category_ID = get_queried_object()->term_id;
* This will get you the current category_ID
*/
$termid = get_term($category_ID, 'product_cat' );
if($termid->parent > 0)
{ // get the parent's hierarchy.
$cat_hierachy = get_ancestors( $category_ID, 'product_cat' );
return end($cat_hierachy); // returns the Level-1 category_ID
}
return $category_ID; // Has no parent so return THIS category_ID Level-1
