I have been searching for hours and the closest I got is overriding breadcrumb.php with the following. It works perfectly on "archive" but on "single_product" depending on the referrer it returns plenty of delimiters ">" (see photo below). Any php savvies that could give me a hand with this please? Thank you so much!
<?php
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
if (!empty($breadcrumb)) {
echo $wrap_before;
if (is_single() && get_post_type() == 'product') {
$breadcrumb_diff = [];
$breadcrumb_diff[] = $breadcrumb[0];
if ($terms = get_the_terms($post->ID, 'product_cat')) {
$referer = wp_get_referer();
$site_url = site_url();
$referer = str_replace($site_url . '', '', $referer);
$referer_array = explode('/', $referer);
foreach ($referer_array as $term_slug) {
$get_term_by_slug = get_term_by('slug', $term_slug, 'product_cat');
$breadcrumb_diff[] = [$get_term_by_slug->name, get_term_link($term_slug, 'product_cat')];
}
$breadcrumb_diff[]= $breadcrumb[count($breadcrumb) - 1];
foreach ($breadcrumb_diff as $key => $crumb) {
echo $before;
if (!empty($crumb[1]) && sizeof($breadcrumb_diff) !== $key + 1) {
echo '<a href="' . esc_url($crumb[1]) . '">' . esc_html($crumb[0]) . '</a>';
} else {
echo esc_html($crumb[0]);
}
echo $after;
if (sizeof($breadcrumb) !== $key + 1) {
echo $delimiter;
}
}
}
} else {
foreach ($breadcrumb as $key => $crumb) {
echo $before;
if (!empty($crumb[1]) && sizeof($breadcrumb) !== $key + 1) {
echo '<a href="' . esc_url($crumb[1]) . '">' . esc_html($crumb[0]) . '</a>';
} else {
echo esc_html($crumb[0]);
}
echo $after;
if (sizeof($breadcrumb) !== $key + 1) {
echo $delimiter;
}
}
}
echo $wrap_after;
}
