Perch Geocode Field Type

A Perch CMS field type for geocoding addresses.


  • PHP 5.3+
  • Perch CMS v2.3.2


  1. Copy perch/addons/fieldtypes/geocode into your project $PERCH/addons/fieldtypes directory.
  2. Download PHP Geocoder into $PERCH/addons/fieldtypes/geocode/php-geocoder.


To use the fieldtype, add into your template as follows:

<perch:content id="address" type="geocode" label="Address" adapter="curl" providers="google_maps openstreetmaps map_quest" required="true" />

Once an address has been successfully geocoded, you'll see a Google Map preview:



The adapter attributes determines which HTTP adapter to use when geocoding. The choices are curl or socket.

The default adapter is curl.


The providers attributes determines which service(s) to use for geocoding. They should be seperated by a single space, and will be executed in the order specified, stopping once a provider returns a result.

The available options are google_maps, google_maps_business, bing_maps, openstreetmaps, map_quest, nominatim, geocoder_ca, geocoder_us, ign_openls, data_science_toolkit, yandex, baidu and tomtom.

The default providers are google_maps, openstreetmaps and map_quest.

Provider Configuration

Providers are configured using constants. For example, the Google Maps provider accepts a region, locale and a useSSL parameter upon construction. The constant names are determined by the name of the provider (e.g., google_maps) and the name of the parameter (e.g., region), capitalised and underscored separated.

You should specify constants in your $PERCH/config/config.php file:

// Your existing Perch configuration…

// Google Maps Provider Configuration.
define('GOOGLE_MAPS_REGION', '');
define('GOOGLE_MAPS_LOCALE', '');
define('GOOGLE_MAPS_USESSL', '');

// Bind Provider Configuration.
define('BING_MAPS_APIKEY', '');
define('BING_MAPS_LOCALE', '');

Check out the PHP Geocoder documentation for more information providers and what parameters their constructors accept.

Note: The specified HTTP adapter is automatically passed to the provider constructor, you only need to configure the remaining parameters.

Accessing Latitude/Longitude Data

The latitude and longitude values, as well as the address entered by the user and any error messages, are stored in the item's JSON:

        "address":      "1218 2nd Avenue South\nLethbridge\nAlberta\nT1J 0E3",
        "addr1":        "1218 2nd Avenue South",
        "addr2":        "",
        "city":         "Lethbridge",
        "state":        "Alberta",
        "postcode":     "T1J 0E3",
        "error":        "",
        "latitude":     49.6974029,
        "longitude":    -112.8277358

You can access this information using Perch's perch_content_custom() method:

$addresses = perch_content_custom('Addresses', array(
	'skip-template' => true,


    [0] => Array
            [_id] => 95
            [name] => Media 32
            [_title] => Media 32
            [address] => Array
                    [address] => 1218 2nd Avenue South
                                 T1J 0E3
                    [addr1] => 1218 2nd Avenue South
                    [addr2] =>
                    [city] => Lethbridge
                    [state] => Alberta
                    [postcode] => T1J 0E3
                    [error] =>
                    [latitude] => 49.6974029
                    [longitude] => -112.8277358
