Only display maximum price for WooCommerce variable products

functions.php

/**
 * Only display maximum price for WooCommerce variable products
 **/
add_filter('woocommerce_variable_price_html', 'custom_variation_price', 10, 2);
 
function custom_variation_price( $price, $product ) {
     
     $price = '';
 
          $price .= woocommerce_price($product->max_variation_price);
 
     return $price;
}

Here is the working code:

/**

• Display the price of the highest priced variation for WooCommerce variable products
  **/
  add_filter('woocommerce_variable_price_html', 'custom_variation_price', 10, 2);

function custom_variation_price( $price, $product ) {
// Get the highest priced variation
$highest_price = $product->get_variation_price('max');

 if ($highest_price > 0) {
     // Display the highest price
     $price = wc_price($highest_price);
 }

 return $price;

}
