Woocommerce breadcrumbs multiple categories

I have e commerce website in wordpress. There are lot of product in it & many product comes under multiple categories like 600 mah Power bank is comes under automobile, IT, media etc. My problem is when i go to the detail of a product there it by default pick up only one category no matter if go through IT category at the end it shows me automobile like this Home / Shop / industry / Automobile / 600 mah Power Bank. But i went to this product via IT so it should show me like this Home / Shop / industry / IT / 600 mah Power Bank.
How can iget path where i come from previous page?

if you are using Woocommerce you can use the following directly, if not it will need adapting but you get the idea:

elseif ( is_single() && ! is_attachment() ) {

if ( get_post_type() == 'product' ) {

echo $prepend;

if ( $terms = get_the_terms( $post->ID, 'product_cat' ) ) {

                $referer = wp_get_referer();
                foreach( $terms as $term){
                    $referer_slug = (strpos($referer, $term->slug));

                        $category_name = $term->name;
                        $ancestors = get_ancestors( $term->term_id, 'product_cat' );
        $ancestors = array_reverse( $ancestors );

                        foreach ( $ancestors as $ancestor ) {
       $ancestor = get_term( $ancestor, 'product_cat' );

                            if ( ! is_wp_error( $ancestor ) && $ancestor )
                                echo $before . '<a href="' . get_term_link( $ancestor->slug, 'product_cat' ) . '">' . $ancestor->name . '</a>' . $after . $delimiter;
                        echo $before . '<a href="' . get_term_link( $term->slug, 'product_cat' ) . '">' . $category_name . '</a>' . $after . $delimiter;

echo $before . get_the_title() . $after;

The main bulk of the work here is done by wp_get_referer which gets the referring URL of the product your visitor has navigated to. The rest of the code checks if a valid category is contained within the URL and uses it in the breadcrumb.
