if( $product->is_type('variable')){
$percentages = array();
// Get all variation prices
$prices = $product->get_variation_prices();
// Loop through variation prices
foreach( $prices['price'] as $key => $price ){
// Only on sale variations
if( $prices['regular_price'][$key] !== $price ){
// Calculate and set in the array the percentage for each variation on sale
$percentages[] = round( 100 - ( floatval($prices['sale_price'][$key]) / floatval($prices['regular_price'][$key]) * 100 ) );
}
}

if ( $sale_price != 0 || ! empty($sale_price) ) {
// Calculate and set in the array the percentage for each child on sale
$percentages[] = round(100 - ($sale_price / $regular_price * 100));
}
}
// We keep the highest value
$percentage = max($percentages) . '%';
} else {
$regular_price = (float) $product->get_regular_price();
$sale_price = (float) $product->get_sale_price();
if ( $sale_price != 0 || ! empty($sale_price) ) {
