当您使用Astra主题时，请try 以下重新访问的代码:

// Inline CSS in the header for single product pages
add_action( 'wp_head', 'simple_product_saving_amount_css', 999 );
function simple_product_saving_amount_css() {
    if ( is_product() ) { ?>
    <style>#saving_total_price {font-size:12px;text-align:center;width:40%;background:lightgoldenrodyellow;margin-bottom:1em;}</style>
    <?php }
}

// For simple products
add_action( 'woocommerce_get_price_html', 'simple_product_saving_amount', 10, 2 );
function simple_product_saving_amount( $price_html, $product ) {
    global $woocommerce_loop;

    if( is_product() && isset($woocommerce_loop['name']) && empty($woocommerce_loop['name']) && $product->is_type('simple') && $product->is_on_sale() ) {
        $regular_price = (float) wc_get_price_to_display( $product, array('price' => $product->get_regular_price() ) );
        $active_price  = (float) wc_get_price_to_display( $product, array('price' => $product->get_sale_price() ) );

        $saved_amount  = $regular_price - $active_price;
        $percentage    = round( $saved_amount / $regular_price * 100 );

        $price_html .= sprintf('<p id="saving_total_price">%s: %s (%s)</p>', __("You Save"), wc_price($saved_amount), $percentage.'%' );
    }
    return $price_html;
}

// For product variations (on variable products)
add_filter( 'woocommerce_available_variation', 'variable_product_saving_amount', 10, 3 );
function variable_product_saving_amount( $data, $product, $variation ) {
    if( $variation->is_on_sale() ) {
        $saved_amount  = $data['display_regular_price'] - $data['display_price'];
        $percentage    = round( $saved_amount / $data['display_regular_price'] * 100 );

        $data['price_html'] .= sprintf('<p id="saving_total_price">%s: %s (%s)</p>', 
            __("You Save"), wc_price($saved_amount), $percentage.'%' );
    }
    return $data;
}
