Error when I add code to show product categories in breadcrumbs

Hello @gusakdmitry ,

It looks like there is some issue with that specific line on that code. I have replaced the problematic en dash with actual “-” minus and the code seems to be working fine. Here is the corrected code again –

/**
 * Show product categories in Woorramework breadcrumbs
 */
// Get breadcrumbs on product pages that read: Home > Shop > Product category > Product Name
add_filter( 'woo_breadcrumbs_trail', 'woo_custom_breadcrumbs_trail_add_product_categories', 20 );
 
function woo_custom_breadcrumbs_trail_add_product_categories ( $trail ) {
  if ( ( get_post_type() == 'product' ) && is_singular() ) {
		global $post;
		
		$taxonomy = 'product_cat';
		
		$terms = get_the_terms( $post->ID, $taxonomy );
		$links = array();
 
		if ( $terms && ! is_wp_error( $terms ) ) {
		$count = 0;
			foreach ( $terms as $c ) {
				$count++;
				if ( $count > 1 ) { continue; }
				$parents = woo_get_term_parents( $c->term_id, $taxonomy, true, ', ', $c->name, array() );
 
				if ( $parents != '' && ! is_wp_error( $parents ) ) {
					$parents_arr = explode( ', ', $parents );
					
					foreach ( $parents_arr as $p ) {
						if ( $p != '' ) { $links[] = $p; }
					}
				}
			}
			
			// Add the trail back on to the end.
			// $links[] = $trail['trail_end'];
			$trail_end = get_the_title($post->ID);
 
			// Add the new links, and the original trail's end, back into the trail.

			print_r(count( $trail ));
			array_splice( $trail, 2, count( $trail ) - 1, $links );
			
			$trail['trail_end'] = $trail_end;
		}
	}
 
	return $trail;
}
 
/**

 */
 
if ( ! function_exists( 'woo_get_term_parents' ) ) {
function woo_get_term_parents( $id, $taxonomy, $link = false, $separator = '/', $nicename = false, $visited = array() ) {
	$chain = '';
	$parent = &get_term( $id, $taxonomy );
	if ( is_wp_error( $parent ) )
		return $parent;
 
	if ( $nicename ) {
		$name = $parent->slug;
	} else {
		$name = $parent->name;
	}
 
	if ( $parent->parent && ( $parent->parent != $parent->term_id ) && !in_array( $parent->parent, $visited ) ) {
		$visited[] = $parent->parent;
		$chain .= woo_get_term_parents( $parent->parent, $taxonomy, $link, $separator, $nicename, $visited );
	}
 
	if ( $link ) {
		$chain .= '<a href="' . get_term_link( $parent, $taxonomy ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $parent->name ) ) . '">'.$parent->name.'</a>' . $separator;
	} else {
		$chain .= $name.$separator;
	}
	return $chain;
	}
}

I hope this helps.

Thank you ??

I already guessed to replace “–” myself, the error disappeared, but breadcrumbs did not appear on the shop pages: https://exileiuy.beget.tech/product/first-product/
Оn other pages breadcrumbs are displayed: https://exileiuy.beget.tech/sample-page/
What am I doing wrong?

Hello @gusakdmitry ,

I am afraid I do not have the exact information regarding this particular snippet.

This is a fairly complex development topic. I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.

I can also recommend the WooCommerce Developer Resources Portal for resources on developing for WooCommerce.

You can also visit the WooCommerce Facebook group or the #developers channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, as well.

If you need a paid solution, you can consider taking help from one of our partner’s website.

Thank you ??
