Advanced Custom Fields: Multiple Coordinates
A multi-point Google Maps field for Advanced Custom Fields. Click to add markers, drag to reposition, right-click to remove.
The plugin reads your existing Google Maps API key from ACF’s global setting (google_api_key), so no extra configuration is needed if you already use ACF Map fields. If you don’t have one set, you can also provide a key via the acf_multi_coords_gmaps_key filter.
Originally inspired by the single-point ACF: Coordinates field by Stupid Studio; this plugin extends the idea to multiple points per field.

Usage
When you create a new custom field with ACF, set the field type to Multiple Coordinates map. The coordinates chooser will then show up when you edit a post with your custom fields.
The tool adds a point on each click on the map. To remove the point, select the “Remove Coordinate” button and click a point. You can also show the points as a polygon on the map with the “Show area on map” button, and show the actual coordinates in a semicolon-separated list with the “Show coordinates” button. The search field is only there to quickly take you to different places on the map — not to add the actual points.
To get the coordinates data on your frontend, simply request the field value and you get the coordinates in a latitude/longitude array plus the zoom level, like this:
<?php
$values = get_field('*****FIELD_NAME*****');
print_r($values);
/* gives you something like:
Array
(
[coords] => Array
(
[0] => Array
(
[lat] => 57.156363766336
[lng] => 16.364327427978
)
[1] => Array
(
[lat] => 57.159612809986
[lng] => 16.370315551758
)
)
[zoom] => 13
)
*/
