Question

I'm using Wordpress with WooCommerce, on the single product page I want to check if one of the product member categories is a member of a parent 'Brands' and if it is display the description from that brand member category.

I've done the following, however it outputs all the categories the product is a member of;

<?php $terms = get_the_terms( $post->ID, 'product_cat' );
if($terms){
foreach($terms as $term){
$category_parent_id = $term->parent;
$category_parent = get_category($category_parent_id);
$category_description = $term->description;
//if(($category_parent = "Brands")){ // THIS DOESNT WORK OUTPUTS ALL CATS
if( "Brands" ==  $category_parent ){ // THIS DOESNT WORK EITHER, OUTPUTS NO RESULTS

$category_name = $term->name;
$category_thumbnail = get_woocommerce_term_meta($term->term_id, 'thumbnail_id', true);
$image = wp_get_attachment_url($category_thumbnail); ?>

Do Some HTML Stuff Here

<?php }
}
} ?>


Brands >
Brands > Brand1 >
Brands > Brand1 > Product
Brands > Brand2 >
Brands > Brand2 > Product
Brands > Brand9999 >
Brands > Brand9999 > Product

If 'Product' is member of 'Brandx' which is a member of 'Brands' then output the description from the 'Brandx' category.

   <?php    $terms = get_the_terms( $post->ID, 'product_cat' );
            if($terms){ 
             foreach($terms as $term){
              $category_name = $term->name;
              $brand_lookup = get_term_by('name', 'Brands', 'product_cat');
              $brand_lookup_id = $brand_lookup->term_id;
              $brand_args = array('hierarchical' => 1,'show_option_none' => '','hide_empty' => 0,'parent' => $brand_lookup_id,'taxonomy' => 'product_cat');
              $brands = get_categories($brand_args);
              foreach ($brands as $brand){
               if($category_name==$brand->name){
                $category_description = $term->description;
                $category_slug = get_term_link( $term );
                $category_thumbnail = get_woocommerce_term_meta($term->term_id, 'thumbnail_id', true);
                $image = wp_get_attachment_url($category_thumbnail);
                echo $category_name; ?>
