Using code to bulk create locations on posts?

  • Hello, I have a tool (for a local history project) that imports placenames to custom posts from sources such as Wikidata. Each placename typically has lat/lon data and also an address string so what I am looking for is a way to programmatically bulk set these values using the generated post ID and, ideally, latlon figures. Can anyone give me any pointers to doing this?

    I have successfully installed the ACF OpenStreetMap Field plugin and am working on the map display.

    Thank you

    I have been trying to investigate this and try a few things. Firstly, if I run acf_get_fields( 3906 ) where 3906 is the ID of the OSM ACF field in the field group, I get

        {
          "center_lat": 55,
          "center_lng": 15,
          "zoom": 15,
          "height": 400,
          "return_format": "raw",
          "allow_map_layers": 1,
          "max_markers": "",
          "layers": [
            
          ],
          "ID": 3909,
          "key": "field_67a416d417344",
          "label": "OSM Location",
          "name": "osmlocation",
          "aria-label": "",
          "prefix": "acf",
          "type": "open_street_map",
          "value": null,
          "menu_order": 0,
          "instructions": "",
          "required": 0,
          "id": "",
          "class": "",
          "conditional_logic": 0,
          "parent": 3906,
          "wrapper": {
            "width": "",
            "class": "",
            "id": ""
          },
          "allow_in_bindings": 1,
          "leaflet_map": "{\"lat\":53.5507112,\"lng\":10.0006485,\"zoom\":12,\"layers\":[],\"markers\":[]}",
          "_name": "osmlocation",
          "_valid": 1
        }

    If I try 

    $lat='52';
    $lon="-2";
    $values = array(
            "lat"   => $lat,
            "lng"   => $lon
    );
    $postId = 1234; // example post of custom post type place
    $updatetGeoResult = update_field('osmlocation', $values, 'place_'.$postId);

    it returns true on first run but then false if I try it again. No obvious changes are visible in the post data after this is run (both when the post has no OSM location set, and when it does)
