Lable percentage for variable product

If i add this code it shows percentage on all product but not in your lable.

add_filter( ‘woocommerce_sale_flash’, ‘add_percentage_to_sale_badge’, 20, 3 );
function add_percentage_to_sale_badge( $html, $post, $product ) {
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
$percentages[] = round(100 – ($prices[‘sale_price’][$key] / $prices[‘regular_price’][$key] * 100));
}
}
// We keep the highest value
$percentage = max($percentages) . ‘%’;
} else {
$regular_price = (float) $product->get_regular_price();
$sale_price = (float) $product->get_sale_price();

$percentage = round(100 – ($sale_price / $regular_price * 100)) . ‘%’;
}
return ‘<span class=”onsale”>’ . esc_html__( ‘SALE’, ‘woocommerce’ ) . ‘ ‘ . $percentage . ‘</span>’;
}

It is not compactibility issue is the issue in code where it doesn’t take varable price for percentage. If i add code aboww with parameter $prices = $product->get_variation_prices(); it shows percentage discount but only outside box.

I have solved problem. In your function you didn’t have option to get variable price. I have changet your code from:

if( ! function_exists( ‘woodmart_product_label’ ) ) {
function woodmart_product_label() {
global $product;

$output = array();

$product_attributes = woodmart_get_product_attributes_label();
$percentage_label = woodmart_get_opt( ‘percentage_label’ );

if ( $product->is_on_sale() ) {

$percentage = ”;

if ( $product->get_type() == ‘variable’ && $percentage_label ) {

$available_variations = $product->get_variation_prices();
$max_percentage = 0;

foreach( $available_variations[‘regular_price’] as $key => $regular_price ) {
$sale_price = $available_variations[‘sale_price’][$key];

if ( $sale_price < $regular_price ) {
$percentage = round( ( ( $regular_price – $sale_price ) / $regular_price ) * 100 );

if ( $percentage > $max_percentage ) {
$max_percentage = $percentage;
}
}
}

$percentage = $max_percentage;
} elseif ( ( $product->get_type() == ‘simple’ || $product->get_type() == ‘external’ ) && $percentage_label ) {
$percentage = round( ( ( $product->get_regular_price() – $product->get_sale_price() ) / $product->get_regular_price() ) * 100 );
}

if ( $percentage ) {
$output[] = ‘<span class=”onsale product-label”>-‘ . $percentage . ‘%’ . ‘</span>’;
}else{
$output[] = ‘<span class=”onsale product-label”>’ . esc_html__( ‘Sale’, ‘woodmart’ ) . ‘</span>’;
}
}

if( !$product->is_in_stock() ){
$output[] = ‘<span class=”out-of-stock product-label”>’ . esc_html__( ‘Sold out’, ‘woodmart’ ) . ‘</span>’;
}

if ( $product->is_featured() && woodmart_get_opt( ‘hot_label’ ) ) {
$output[] = ‘<span class=”featured product-label”>’ . esc_html__( ‘Hot’, ‘woodmart’ ) . ‘</span>’;
}

if ( get_post_meta( get_the_ID(), ‘_woodmart_new_label’, true ) && woodmart_get_opt( ‘new_label’ ) ) {
$output[] = ‘<span class=”new product-label”>’ . esc_html__( ‘New’, ‘woodmart’ ) . ‘</span>’;
}

if ( $product_attributes ) {
foreach ( $product_attributes as $attribute ) {
$output[] = $attribute;
}
}

if ( $output ) {
echo ‘<div class=”product-labels labels-‘ . woodmart_get_opt( ‘label_shape’ ) . ‘”>’ . implode( ”, $output ) . ‘</div>’;
}
}
}
add_filter( ‘woocommerce_sale_flash’, ‘woodmart_product_label’, 10 );
