Geocode look up of Latitude and Longitude using Googles Geocode service for the CP. The fieldtype has 3 fields: one is editable for the address and the other two show the returned co-ordinates. All three fields or the combined co-ordinate is available. There's also a little map preview of the returned co-ordinates so the user can check if Google has found the right place!
Google Maps V3 is a great (mostly free) Maps service to use on your clients websites. This fieldtype was developed to overcome the requirements for Google Map’s markers.
Google Maps requires the Latitude and Longitude to place a marker. Generally people don’t know their position on the earth by this data! Handily Google also has geocoding to look up written address details and return the the Lat/Lng co-ordinates. It is possible to add a standard text area fieldtype to EE for the user to enter an address and then in the template use geocoding to find the Lat/Lng and then position a marker on the Map.
The problem with this approach is, if you had 20 markers to place on the map every page refresh will hit Geocode 20 times for the same data. This isn’t very efficient and could use up your usage limit. These co-ordinates should be stored for later usage. This fieldtype does the Geocode lookup in the CP so the Lat/Lng is stored in EEs database.
The fieldtype has 3 fields, 1 is editable for the address and the other 2 show the returned co-ordinates. All 3 fields or the combined co-ordinate is available.
There’s also a little map preview of the returned co-ordinates so the user can check if Googles found the right place! There’s Global Settings for default values every time the fieldtype is added to a field group and default settings at a field group level.
Technically this isn’t true, https://developers.google.com/maps/documentation/geocoding/
The Geocoding API may only be used in conjunction with a Google map; geocoding results without displaying them on a map is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions.

1. Add-ons -> Fieldtypes -> Google Maps Lat Lng Lookup -> Install]
2. The title (Google Maps Lat Lng Lookup) becomes a link, click to change the Global default.
3. Admin -> Channel Fields -> Add New Field.
4. Change the default settings for this Channel Field.
Eg. Assuming you’ve named your fieldtype ‘geo_address’ in step 4 above.
Outputs Latitude and Longitude comma separated for direct usage with Google Maps.
The address the user entered. In case you need to display that as well.
Eg. Trafalgar Square, City of Westminster, WC2N 5DN
Just the Latitude.
Just the Longitude.
- Data saved to DB as pipe delimited string, so added validation against address field containing | character. https://github.com/elliotlewis/Google-Latlng-Lookup/issues/4
- Altered validate method so empty values validate (thanks to Creative Lynx)
- Added SafeCracker compatibility
- Allowed fine tuning of co-ordinates by adjusting form values
- Fixed silly error where I was directly accessing the LatLng object instead of using built in function to return the co-ordinates
- Added more error feedback
- Feedback on type of result returned, Eg. Approximate location
1st release. Global and Channel Field default settings
