woocommerce - How do I get the most top level category of the current product category
or maybe this:
$cat = get_the_terms( $product->ID, 'product_cat' );
foreach ($cat as $categoria) {
if($categoria->parent == 0){
echo $categoria->name;
}
}
After a lot of research I figured a way to solve this. I hope this will help someone.
solution:
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>' . $last_parent_cat_value . '</strong>';
}
}
Here the solution i actually use
function get_parent_terms($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);
