@updownupdown Hi, once you add code for google maps for acf, you need to input the coordinates of polygon:
// center map
center_map( map );
// Define the LatLng coordinates for the polygon.
var triangleCoords = [
{lat: 44.28223, lng: 20.63992},
{lat: 44.28253, lng: 20.63935},
{lat: 44.28301, lng: 20.63984},
{lat: 44.28226, lng: 20.64103},
{lat: 44.28246, lng: 20.64138},
{lat: 44.28192, lng: 20.64267},
{lat: 44.2812, lng: 20.64186},
{lat: 44.28206, lng: 20.63973}
];
// Construct the polygon.
var bermudaTriangle = new google.maps.Polygon({
paths: triangleCoords,
strokeColor: '#FF0000',
strokeOpacity: 0.8,
strokeWeight: 3,
fillColor: '#FF0000',
fillOpacity: 0.35
});
bermudaTriangle.setMap(map);
// Add a listener for the click event.
bermudaTriangle.addListener('click', showArrays);
infoWindow = new google.maps.InfoWindow;
// }
after that you can render the polygon with this piece of code:
/** @this {google.maps.Polygon} */
function showArrays(event) {
// Since this polygon has only one path, we can call getPath() to return the
// MVCArray of LatLngs.
var vertices = this.getPath();
var contentString = '<b>Bermuda Triangle polygon</b><br>' +
'Clicked location: <br>' + event.latLng.lat() + ',' + event.latLng.lng() +
'<br>';
// Iterate over the vertices.
for (var i =0; i < vertices.getLength(); i++) {
var xy = vertices.getAt(i);
contentString += '<br>' + 'Coordinate ' + i + ':<br>' + xy.lat() + ',' +
xy.lng();
}
// // Replace the info window's content and position.
// Turned off since i didn't need the rendering of tooltip over polygon.
// infoWindow.setContent(contentString);
// infoWindow.setPosition(event.latLng);
// infoWindow.open(map);
}
And that is it 🙂
Here is the code i use for google maps on one of the wp website where i needed polygon area:
<style type="text/css">
.acf-map {
width: 100%;
height: 400px;
border: #ccc solid 1px;
/* margin: 20px 0; */
}
/* fixes potential theme css conflict */
.acf-map img {
max-width: inherit !important;
}
</style>

and i used this polygon render by google as starting point, and of course the pen u mentioned earlier to get the coordinates of the polygon i needed.
