ACF Get Directions map link

acf_get_directions.php

<?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>';
 endif;
?>
<p>This should produce a link like this:</p>
<a href="https://www.google.com/maps/dir/?api=1&destination=51.072159,1.088130">Get directions</a>

See <a href="https://developers.google.com/maps/documentation/urls/get-started#directions-action">https://developers.google.com/maps/documentation/urls/get-started#directions-action</a>
    

Sweet, thanks for that :)

ryan-noakes answer won't work, you have to replace the spaces by + signs like a google map url would do :

https://www.google.com/maps/place/<?php echo str_replace(' ','+',$location['address']); ?>"

It works everytime for me and is smaller in code than the first answer.

Added urlencode:
$map_link = 'https://www.google.com/maps/place/' . urlencode( str_replace( ' ', '+' , $map['address'] ) );

this just saved me a lot of work thank you

Really thanks, but i change

$map_link = 'https://www.google.com/maps/place/' . urlencode( str_replace( ' ', '+' , $map['address'] ) );
by :
$map_link = 'https://www.google.com/maps/place/' . urlencode( str_replace( '% ', ' ' , $map['address'] ) );
it's little but its work better :)

$map_link = 'https://www.google.com/maps/search/?api=1&query=' . urlencode( str_replace( '% ', ' ' , $map['address'] ) );
Check the https://developers.google.com/maps/documentation/urls/guide

I use this:
$map_link = 'https://www.google.com/maps/dir/?api=1&destination=' . $location['lat'] .','. $location['lng'];
<a class="directions" href="'. $map_link .'" target="_blank">Chỉ đường</a>

Is there anybody who got it worked? The one JetLewis provided don't work for me, it brings me just to Google Maps without any data from the ACF field

it does not work for me...It send to the page with adress but the map is not centered and there is no marker

@Picpool The Maps API has changed a bit since 2015. I've updated the gist.

To create a link pointing directly to the location in Google Maps

<?php
$location = get_field('luogo_evento');
if (!empty($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>';
}
?>
