# Maps2 API {#developer-api}

Maps2 comes with some public methods which we have marked with `@api`. Use
them to simplify your life within your extensions when working with maps2.

## GeoCodeService {#geocodeservice}

### getFirstFoundPositionByAddress {#getfirstfoundpositionbyaddress}

Give it an address (string) as first argument and you will get first found
address as Position object. If the geocoding service has nothing found or an
error occurs this method will return `null`. There is no need to
:php:rawurlencode the address as we will do it for you.

### getPositionsByAddress {#getpositionsbyaddress}

Give it an address (string) as first argument and you will get all found results
from geocoding service as Position object in an ObjectStorage.

### getGeoCodeResult {#getgeocoderesult}

Same as `getPositionsByAddress`, but returns a `GeoCodeResult` value object
containing the found positions or the error, why the address could not be
geocoded. Use it, if you want to show a meaningful message to your users.

`$result->error->type` is a case of the provider independent enum
`\JWeiland\Maps2\Client\ClientErrorEnum`:

-   **`NO_POSITIONS_FOUND`**

    The map provider did not find the address. Ask the user to check the
    input.

-   **`REQUEST_DENIED`**

    The map provider rejected the request, e.g. because of an invalid API key or
    because the API key is restricted to other IP addresses.

-   **`QUOTA_EXCEEDED`**

    The request limit or the quota of the map provider was exceeded.

-   **`INVALID_REQUEST`**

    The map provider did not accept the request.

-   **`INVALID_RESPONSE`**

    The response of the map provider is not valid JSON.

-   **`SERVICE_ERROR`**

    The map provider could not be reached or answered with an unknown error.

Only `NO_POSITIONS_FOUND` is caused by the user input. `$result->error->message`
contains the technical message of the map provider. Please don't show it to
frontend users, as it may contain sensitive data like the IP address of your
server.

```php
$result = $this->geoCodeService->getGeoCodeResult($address);
$position = $result->getFirstPosition();
if ($position === null) {
    $message = match ($result->error?->type) {
        ClientErrorEnum::NO_POSITIONS_FOUND => 'Please check your address',
        default => 'Address lookup is currently not possible',
    };
}
```

## MapService {#mapservice}

### createNewPoiCollection {#createnewpoicollection}

Use it, if you have some location records in your extension and want to create
a new PoiCollection relation automatically while saving your location record.

### assignPoiCollectionToForeignRecord {#assignpoicollectiontoforeignrecord}

We have over 5 extensions working together with maps2 and we always have to
implement a part to save the PoiCollection UID to our other extensions. Wouldn't
it be better to have a centralized method doing that?

### addForeignRecordsToPoiCollection {#addforeignrecordstopoicollection}

This method is NOT public API. It will be called automatically, if you call
getForeignRecords of a PoiCollection. It contains a SignalSlot where you can
remove or modify foreignRecords before adding them to PoiCollection.

#### Example {#example}

Here we have a working example out of our extension events2:

```php
// create new map-record and set it in relation
$position = $this->googleMapsService->getFirstFoundPositionByAddress($this->getAddress($eventLocation));
if ($position instanceof Position) {
    $tsConfig = $this->getTsConfig($eventLocation);
    $this->googleMapsService->assignPoiCollectionToForeignRecord(
        $this->googleMapsService->createNewPoiCollection(
            (int)$tsConfig['pid'],
            $position,
            array(
                'title' => $eventLocation['location']
            )
        ),
        $eventLocation,
        'tx_events2_domain_model_location',
        'tx_maps2_uid'
    );
}
```

## MapRegistry {#mapregistry}

### getColumnRegistry {#getcolumnregistry}

Get the Maps2 registry as ColumnRegistrationStorage object for all
tables, columns and its configuration.

We have added a service `maps2.columnRegistry` to `Services.yaml` which you can
use for your extensions:

```yaml
MyVendor\MyExtension\Service\MyService:
  arguments:
    $columnRegistry: '@maps2.columnRegistry'
```
