How to customize WooCommerce Breadcrumbs [duplicate] - css

Question

I'm using the following function to remove the product title from the breadcrumbs displayed on the product page:
add_filter( 'woocommerce_get_breadcrumb', 'ed_change_breadcrumb' );
function ed_change_breadcrumb( $breadcrumb ) {
if(is_singular()){
array_pop($breadcrumb);
}
return $breadcrumb;
}
It works in that it does remove the title, but it also stops the last category/sub-category from being a hyperlink. How can I fix that?
For example:
Original breadcrumb
<a>Home</a> / <a>Category</a> / <a>Sub Category</a> / Product Title
Result of the above function
<a>Home</a> / <a>Category</a> / Sub Category
I need the Sub Category to still be clickable after removing the product title from the breadcrumbs.
Thanks

Your code works but the last element in the breadcrumbs never contains a link through the code used in global/breadcrumb.php template file on line 34
This template can be overridden by copying it to yourtheme/woocommerce/global/breadcrumb.php.
So you can remove your filter hook and apply the following code in the template file so that it provides a link to the last element when is_product() is true
Note: is_product() - Returns true on a single product page. Wrapper for is_singular()
Replace
if ( ! empty( $breadcrumb ) ) {
echo $wrap_before;
foreach ( $breadcrumb as $key => $crumb ) {
echo $before;
if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key + 1 ) {
echo '' . esc_html( $crumb[0] ) . '';
} else {
echo esc_html( $crumb[0] );
}
echo $after;
if ( sizeof( $breadcrumb ) !== $key + 1 ) {
echo $delimiter;
}
}
echo $wrap_after;
}
With
if ( ! empty( $breadcrumb ) ) {
echo $wrap_before;
foreach ( $breadcrumb as $key => $crumb ) {
echo $before;
if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key + 1 ) {
echo '' . esc_html( $crumb[0] ) . '';
} else {
if ( is_product() ) {
unset($crumb);
} else {
echo esc_html( $crumb[0] );
}
}
echo $after;
if ( sizeof( $breadcrumb ) !== $key + 1 ) {
if ( is_product() && sizeof( $breadcrumb ) == $key + 2 ) {
echo '';
} else {
echo $delimiter;
}
}
}
echo $wrap_after;
}
