3rd level child on breadcrumbs in woocommerce not working - php

Question

I have here a code that works fine except for the woocommerce product page
for example:
Home > category1 > category2 > category3
but when I go to the product page it shows only like this
Home > category1 > product
I need it to show in the product page
Home > category1 > category2 > category3 > product
I think this is where to modify the code
( if ( get_post_type() == 'product' ) {} )
Here is the code below:
function limelight_breadcrumbs()
{
global $post, $wp_query;
if ( ! $home ) $home = __( 'Home', 'limelight' );
$home_link = home_url();
$delimiter = ' » ';
$currentBefore = '<span class="current">';
$currentAfter = '</span>';
$wrap_before = ' <nav id="breadcrumbs">';
$wrap_after = '</nav> ';
if ( get_option('woocommerce_prepend_shop_page_to_urls') == "yes" && woocommerce_get_page_id( 'shop' ) && get_option( 'page_on_front' ) !== woocommerce_get_page_id( 'shop' ) )
$prepend = '' . get_the_title( woocommerce_get_page_id('shop') ) . ' ' . $delimiter;
else $prepend = '';
if ( ( ! is_front_page() && ! ( is_post_type_archive() && get_option( 'page_on_front' ) == woocommerce_get_page_id( 'shop' ) ) ) || is_paged() ) {
echo $wrap_before . '<a class="home" href="' . $home_link . '">' . $home . '</a> ' . $delimiter ;
if ( is_category() ) {
$cat_obj = $wp_query->get_queried_object();
$this_category = get_category( $cat_obj->term_id );
if ( $this_category->parent != 0 ) {
$parent_category = get_category( $this_category->parent );
echo get_category_parents($parent_category, TRUE, $delimiter );
}
echo $currentBefore . single_cat_title( '', false ) . $currentAfter;

} elseif ( is_tag() ) {

}
if ( get_query_var( 'paged' ) )
echo ' (' . __( 'Page', 'limelight' ) . ' ' . get_query_var( 'paged' ) . ')';

}
}
I can't seem to do anything on this and I don't know how.

Answer 1

solved it by inserting pieces of code
$taxonomy = 'product_cat'; //change to your taxonomy name
// get the term IDs assigned to post.
$post_terms = wp_get_object_terms( $post->ID, $taxonomy, array( 'fields' => 'ids' ) );
// separator between links
$separator = $delimiter;
if ( !empty( $post_terms ) && !is_wp_error( $post_terms ) ) {
$term_ids = implode( ',' , $post_terms );
$terms = wp_list_categories( 'title_li=&style=none&echo=0&taxonomy=' . $taxonomy . '&include=' . $term_ids );
$terms = rtrim( trim( str_replace( '<br />', $separator, $terms ) ), $separator );
// display post categories
echo $terms . $delimiter;
}
so this will show all the categories related to the product, hope i am right... but works fine
