I have tried to create a ‘Proximity’ Facet which connects to the google maps metabox field – the LAT/LONG of the address. It doesnt seem to work, nor does it register the location coordinates in the facetwp index table in db.
here is my meta box map field
[ 'id' => $prefix . 'map_lat_long', 'type' => 'map', 'name' => esc_html__( 'Map', 'text-domain' ), 'address_field' => 'building_address', 'api_key' => '...', 'region' => '.us', 'std' => '40.7831, -73.9712,14', ],
The documentation states it can filter by lat/long: https://facetwp.com/documentation/facets/facet-types/proximity/
It also says “The Data Source should be a custom field containing a comma-separated latitude, longitude.”
My map field in the custom table is stored exactly like this (provided an address is selected via the meta box building_address field).
