Resolving Price Display Issues for Variable Products in WooCommerce: Fixing Sale

Hi

We are using a code on our website that you previously developed to swap the display of the sale price and the regular price of a product. The issue with this code is that for variable products, it merges the regular price and the sale price into one. With this code, both output prices are the same, meaning the sale price and the regular price are identical. The code is as follows:

function custom_pric_sale_price_html( $price, $product ) {
    if ( $product->is_on_sale() ) {
        $regular_price = wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) );
        $sale_price = wc_get_price_to_display( $product, array( 'price' => $product->get_sale_price() ) );
        $price = '<del>' . wc_price( $regular_price ) . '</del> <br> <ins>' . wc_price( $sale_price ) . '</ins>';
    }
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'custom_pric_sale_price_html', 10, 2 );

I also found these codes but they don’t work

function custom_pric_sale_price_html( $price, $product ) {
    if ( $product->is_on_sale() ) {
        $regular_price = $product->get_regular_price();
        $sale_price = $product->get_sale_price();

        $regular_price_display = wc_get_price_to_display( $product, array( 'price' => $regular_price ) );
        $sale_price_display = wc_get_price_to_display( $product, array( 'price' => $sale_price ) );

        $price = '<del>' . wc_price( $regular_price_display ) . '</del> <br> <ins>' . wc_price( $sale_price_display ) . '</ins>';
    } else {
        $regular_price_display = wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) );
        $price = wc_price( $regular_price_display );
    }

    return $price;
}
add_filter( 'woocommerce_get_price_html', 'custom_pric_sale_price_html', 10, 2 );

or

function custom_pric_sale_price_html( $price, $product ) {
    if ( $product->is_on_sale() ) {
        $regular_price = $product->get_regular_price();
        $sale_price = $product->get_sale_price();

        $regular_price_display = wc_get_price_to_display( $product, array( 'price' => $regular_price ) );
        $sale_price_display = wc_get_price_to_display( $product, array( 'price' => $sale_price ) );

        $price = '<del>' . wc_price( $regular_price_display ) . '</del> <br> <ins>' . wc_price( $sale_price_display ) . '</ins>';
    } else {
        $regular_price_display = wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) );
        $price = wc_price( $regular_price_display );
    }
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'custom_pric_sale_price_html', 10, 2 );

        // Get the variation prices
        $regular_price = $product->get_regular_price();
        $sale_price = $product->get_sale_price();
        
        // Check if sale price and regular price are not the same
        if ( $regular_price !== $sale_price ) {
            $regular_price_display = wc_get_price_to_display( $product, array( 'price' => $regular_price ) );

        } else {
            // If they are the same

or

    if ( $product->is_on_sale() && $product->is_type('variable') ) {
        $regular_price = $product->get_regular_price();
        $sale_price = $product->get_sale_price();
        
        if ( $regular_price !== $sale_price ) {

        }
    }
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'custom_pric_sale_price_html', 10, 2 );

How can I resolve this issue?
