[WOOCOMMERCE] Breadcrumbs not working properly

Hey aderal2016,

This is not a bug – by default the breadcrumb function will “cut” the hierarchy with the first child category. However you can easily overwrite the default breadcrumb function with this code – you can add it to the child theme functions.php:

add_filter('avia_breadcrumbs_trail','avia_custom_woocommerce_breadcrumb', 15, 2 );

function avia_custom_woocommerce_breadcrumb( $trail, $args )
{
	global $avia_config;

	if(is_woocommerce())
	{
		$front_id	= avia_get_option('frontpage');
		$home 		= isset( $trail[0] ) ? $trail[0] : '';
		$last 		= array_pop($trail);
		$shop_id 	= function_exists( 'wc_get_page_id' ) ? wc_get_page_id( 'shop' ) : woocommerce_get_page_id( 'shop' );
		$taxonomy 	= "product_cat";

		// 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 = ( empty( $home ) ) ? array() : array( 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)) 
			{ 
				foreach ($product_category as $key => $data)
				{
					$trail[] = '<a href="' . get_term_link( $product_category[$key]->slug, $taxonomy ) . '" title="' . esc_attr( $product_category[$key]->name ) . '">' . $product_category[$key]->name . '</a>';
				}
			}

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

	return $trail;
}

Hi,

I added the code for you and the error is gone now :)

You can i.e. test it here: https://www.aderal.es/desarrollo/onwa/producto/campana-extractora-ct60z/
