<?php
 $location = get_field('map_location');
  if ( !empty( $location ) ) :
   $map_url = 'https://www.google.com/maps/dir/?api=1&destination=' . $location['lat'] . ',' . $location['lng'];
   echo '<a href=". esc_url( $map_url ) . '" rel="nooopener">Get directions</a>';

?>

$location = get_field('luogo_evento');
if (!empty($location)) {
   $street = $location['street_name'] . ' ' . $location['street_number'];
   $city = $location['city'];
   $address = urlencode("{$street}, {$city}");
   $lat = $location['lat'];
   $lng = $location['lng'];
   $map_link = "https://www.google.com/maps/search/?api=1&query=$address";
   echo '<a class="directions" href="' . $map_link . '" target="_blank">' . $street . ' - ' . $city . '</a>';
