The following code will display the discount saved under the price for both simple and variable products. But when I install the snippet code as suggested here "Replace the Variable Price range by the chosen variation price in WooCommerce 3", the discount saved for the variable products disappeared.
// For simple products
add_action( 'woocommerce_single_product_summary', 'simple_product_saving_amount', 11 );
function simple_product_saving_amount() {
global $product;
if( $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 / $regular_price * 100 );
echo '<p id="saving_total_price">'. __("You Save") .': ' . wc_price($saved_amount) . ' ('.$percentage.'%)</p>';
}
}
// 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 );
$data['price_html'] .= '<p id="saving_total_price">'. __("You Save") .': ' . wc_price($saved_amount) . ' ('.$percentage.'%)</p>';
}
return $data;
}
