- All code can be found and developed on github: https://github.com/b13/geocoding/
Introduction
This extension provides an abstract way to get geo coordinates of addresses around the world. "Geocoding" let's you fetch information about an address and stores it in the DB, by using the TYPO3 Caching Framework to store the queries and results.
Installation
Use composer req b13/geocoding
or install it via TYPO3's Extension Manager from the TYPO3 Extension Repository using the extension key geocoding
.
Configuration
Fetch a Google API key (https://code.google.com/apis/console) and add it to the extension configuration info in the Extension Manager. For more information see here: https://developers.google.com/maps/documentation/geocoding/?hl=en
How to use
Instantiate the class via GeneralUtility::makeInstance()
in your TYPO3 extension. Then use the public methods.
GeoService
The extension provides you with a clean PHP/TYPO3 extension abstraction to fetch latitude and longitude for a specific address string. This is done in the GeoService
Service PHP class.
GeoService->calculateCoordinatesForAllRecordsInTable
If you need to query user input, a JavaScript API is probably the best way to do so. However, it can be done via JS as well, by calling GeoService->getCoordinatesForAddress($street = NULL, $zip = NULL, $city = NULL, $country = 'Germany')
$geoServiceObject = GeneralUtility::makeInstance(\B13\Geocoding\Service\GeoService::class);
$coordinates = $geoServiceObject->getCoordinatesForAddress('Breitscheidstr. 65', 70176, 'Stuttgart', 'Germany');
The method does internal caching of the same requests.
GeoService->calculateCoordinatesForAllRecordsInTable
The method GeoService->calculateCoordinatesForAllRecordsInTable($tableName, $latitudeField, $longitudeField, $streetField, $zipField, $cityField, $countryField, $addWhereClause)
allows you to bulk-encode latitude and longitude fields for existing addresses. The call can easily be built inside a Scheduler Task (see example below).
This way you can fetch the information about an address of a DB record (e.g. tt_address) and store the data in the database table, given that you add two new fields latitude and longitute to that target table in your extension (no TCA information required for that).
Example: Using GeoService as a Scheduler Task for tt_address
Put this into EXT:my_extension/Classes/Task/GeocodingTask.php
:
<?php namespace MyVendor\MyExtension\Task; /** * Class to be called by the scheduler to * find geocoding coordinates for all tt_address records */ class GeocodingTask extends \TYPO3\CMS\Scheduler\Task\AbstractTask { /** * Function executed from the Scheduler. */ public function execute() { /** @var \B13\Geocoding\Service\GeoService $geocodingService */ $geocodingService = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\B13\Geocoding\Service\GeoService::class); $geocodingService->calculateCoordinatesForAllRecordsInTable( 'tt_address', 'latitude', 'longitude', 'address', 'zip', 'city', 'country' ); return true; } }
And also register this class within ext_localconf.php
of your extension:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['scheduler']['tasks'][\MyVendor\MyExtension\Task\GeocodingTask::class] = [ 'extension' => 'myextension', 'title' => 'Geocoding of address records', 'description' => 'Check all tt_address records for geocoding information and write them into the fields' ];
RadiusService
The other main service class is used for the calculating distances between two coordinates (RadiusService->getDistance()
, and querying records from a DB table with latitude and longitude (works perfectly in conjunction with calculateCoordinatesForAllRecordsInTable()
) given a certain radius and base coordinates.
