Putting regular price and sale price on woocommerce variation dropdown menu - php

Question

First time posting here so please bear with me. I am using the following code:
function display_price_in_variation_option_name( $term ) {
global $wpdb, $product;
$result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );
$term_slug = ( !empty( $result ) ) ? $result[0] : $term;
$query = "SELECT postmeta.post_id AS product_id
FROM {$wpdb->prefix}postmeta AS postmeta
LEFT JOIN {$wpdb->prefix}posts AS products ON ( products.ID = postmeta.post_id )
WHERE postmeta.meta_key LIKE 'attribute_%'
AND postmeta.meta_value = '$term_slug'
AND products.post_parent = $product->id";
$variation_id = $wpdb->get_col( $query );
$parent = wp_get_post_parent_id( $variation_id[0] );
if ( $parent > 0 ) {
$_product = new WC_Product_Variation( $variation_id[0] );
return $term . woocommerce_price( $_product->get_price() );
}
return $term;
}
add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name' );
This code puts a price next to each item in a variations menu. What I'd like to do is to have it also post a sale price and have the regular price be struck through (as in, here's the regular price and the sale price).
I tried the following:
$regular_price = woocommerce_price( $_product->get_regular_price() );
$sale_price = woocommerce_price( $_product->get_price() );
return $term . $regular_price . $sale_price;
And while that does add in a sale price it also has the sale price and regular prices overlap. I guess what I am looking for is a way to format the prices.
Any help is appreciated.
Thanks

You can add a bit of HTML within the Filter to add spaces and strike-through the original price. You can use following code
$regular_price = woocommerce_price( $_product->get_regular_price() );
$sale_price = woocommerce_price( $_product->get_price() );
return $term . '&nbsp' . '<strike>' . $regular_price . '</strike>' . '&nbsp'. $sale_price;
