Reply To: Price of products in theme options

I fixed that

function solde_sale_price_html( $price, $product ) {
    if ( $product->is_on_sale() ) {
        $sale_price = wc_get_price_to_display( $product );
        $regular_price = $product->get_regular_price();
        
        if ( $sale_price > 0 ) {
            $price = '<ins>' . wc_price( $sale_price ) . '</ins> <br>  <del>' . wc_price( $regular_price ) . '</del>';
        }
    }
    return $price;
}
add_filter( 'woocommerce_get_price_html', 'solde_sale_price_html', 10, 2 );
