Backlink to product category on single product page

Hi Shorty05!

Thank you for using Enfold.

Do you want to display only one product category in the breadcrumb? Please add this in the functions.php file:

add_action('after_setup_theme', 'ava_modify_product_breadcrumb');
function ava_modify_product_breadcrumb() {
	remove_filter('avia_breadcrumbs_trail','avia_woocommerce_breadcrumb');
	add_filter('avia_breadcrumbs_trail','avia_woocommerce_breadcrumb_mod');
}

function avia_woocommerce_breadcrumb_mod($trail)
{
	global $avia_config;

	if(is_woocommerce())
	{

		$home 		= $trail[0];
		$last 		= array_pop($trail);
		$shop_id 	= woocommerce_get_page_id('shop');
		$taxonomy 	= "product_cat";

		// on the shop frontpage simply display the shop name, rather than shop name + "All Products"
		if(is_shop())
		{
			if(!empty($shop_id) && $shop_id  != -1)  $trail = array_merge( $trail, avia_breadcrumbs_get_parents( $shop_id ) );
			$last = "";

			if(is_search())
			{
				$last = __('Search results for:','avia_framework').' '.esc_attr($_GET['s']);
			}
		}

		// on the product page single page modify the breadcrumb to read [home] [if available:parent shop pages] [shop] [if available:parent categories] [category] [title]
		if(is_product())
		{
			//fetch all product categories and search for the ones with parents. if none are avalaible use the first category found
			$product_category = $parent_cat = array();
			$temp_cats = get_the_terms(get_the_ID(), $taxonomy);

			if(!empty($temp_cats))
			{
				foreach($temp_cats as $key => $cat)
				{
					if($cat->parent != 0 && !in_array($cat->term_taxonomy_id, $parent_cat))
					{
						$product_category[] = $cat;
						$parent_cat[] = $cat->parent;
					}
				}

				//if no categories with parents use the first one
				if(empty($product_category)) $product_category[] = reset($temp_cats);

			}
			//unset the trail and build our own
			unset($trail);

			$trail[0] = $home;
			if(!empty($shop_id) && $shop_id  != -1)    $trail = array_merge( $trail, avia_breadcrumbs_get_parents( $shop_id ) );
			//if(!empty($parent_cat)) $trail = array_merge( $trail, avia_breadcrumbs_get_term_parents( $parent_cat[0] , $taxonomy ) );
			if(!empty($product_category)) $trail[] = '<a href="' . get_term_link( $product_category[0]->slug, $taxonomy ) . '" title="' . esc_attr( $product_category[0]->name ) . '">' . $product_category[0]->name . '</a>';

		}

		// add the [shop] trail to category/tag pages: [home] [if available:parent shop pages] [shop] [if available:parent categories] [category/tag]
		if(is_product_category() || is_product_tag())
		{
			if(!empty($shop_id) && $shop_id  != -1)
			{
				$shop_trail = avia_breadcrumbs_get_parents( $shop_id ) ;
				array_splice($trail, 1, 0, $shop_trail);
			}
		}

		if(is_product_tag())
		{
			$last = __("Tag",'avia_framework').": ".$last;
		}

		if(!empty($last)) $trail[] = $last;
	}

	return $trail;
}
