Nette addon. Viewer and picker for Google maps

This branch is for Nette 3.0

Version	PHP	Recommended Nette
dev-master	>= 8.0	Nette 3.0 (Nette\SmartObject)
1.4.x	>= 8.0	Nette 3.0 (current; Maps JS v3.56+ Advanced Markers)
1.3.x	>= 8.0	Nette 3.0 (Nette\SmartObject)
1.2.x	>= 7.1	Nette 2.4 (Nette\SmartObject)
1.1.x	>= 5.3.7	Nette 2.4, 2.3 (Nette\Object)
1.0.x	>= 5.3.7	Nette 2.4, 2.3 (Nette\Object)

Version 1.4.0 (Maps JavaScript API 2023–2024+)

Asynchronous API load: the recommended pattern uses async on the script tag, query parameters loading=async and callback=netteGMapGoogleApiReady, and the marker library alongside places (libraries=places,marker). The global function window.netteGMapGoogleApiReady is defined in jquery.netteGMap.js and must be loaded before the Google Maps script so the callback exists when the API finishes loading.
Advanced markers: legacy google.maps.Marker is replaced by google.maps.marker.AdvancedMarkerElement (deprecation notice from February 2024). Map options include mapId; if you do not set a Map ID in PHP, the client uses Google’s DEMO_MAP_ID (suitable for development; for production, create a Map ID in Google Cloud Console and set it with setMapId() on the control).
Info windows use infowindow.open({ map, anchor }) for advanced markers. Custom marker icons use the content option with an <img> node.
Geocoding requests use the location field instead of the deprecated latLng key.
Bugfix: the viewer with a fixed center no longer referenced an out-of-scope mapProp variable; map.setCenter() is used instead.
Draggable picker: dragend is bound once on the picker marker; repeated updates no longer stack duplicate listeners.

Při aktualizaci z 1.3.x je nutné upravit načtení skriptu v šabloně (viz Configuration) a zkontrolovat pořadí: jQuery → jquery.netteGMap.js → asynchronní tag Maps API s callback=netteGMapGoogleApiReady.

Installation

Install with composer:

composer require venca-x/nettegmap:^1.4

(Or dev-master for the latest commit.)

You need use jQuery.

Configuration
-------------

bootstrap.php add register line OR add line in config.neon

```php
Nette\Forms\NetteGMapPicker::register();//require only form picker

OR add line to config.neon:

extensions:
    nettegmap: Nette\Forms\NetteGMapPicker

<link rel="stylesheet" media="screen,projection,tv" href="{$basePath}/css/netteGMap.css">

<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<!-- Defines window.netteGMapGoogleApiReady; must run before the Maps API script. -->
<script src="{$basePath}/js/jquery.netteGMap.js"></script>
<script async src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&amp;libraries=places,marker&amp;loading=async&amp;callback=netteGMapGoogleApiReady"></script>
<script src="{$basePath}/js/main.js"></script>

Generate YOUR_API_KEY in Google Cloud Console (APIs & Services → Credentials).
Enable Maps JavaScript API and, for the picker search box, a Places-compatible API (e.g. Places API / Places API (New) as required by your project).
The URL must include libraries=places,marker (marker library is required for advanced markers), loading=async, and callback=netteGMapGoogleApiReady (must match the function name in jquery.netteGMap.js).

Volitelné — vlastní Map ID (doporučeno pro produkci): v Cloud Console vytvořte Map ID a v presenteru / komponentě zavolejte např. $viewer->setMapId('VÁŠ_MAP_ID'); (metoda je na společné bázi BaseNetteGMap). Bez nastavení zůstává fallback DEMO_MAP_ID v prohlížeči.

Usage with Bower / bundler

Load the Google Maps script after the bundle that includes jquery.netteGMap.js, with callback=netteGMapGoogleApiReady and libraries=places,marker (see Configuration). Example Grunt/Gulp order:

concat: {
    js: {
        src: ['bower_components/jquery/dist/jquery.min.js',
            'vendor/nette/forms/src/assets/netteForms.js',
            'bower_components/bootstrap/dist/js/bootstrap.min.js',
            'vendor/venca-x/nettegmap/client/js/jquery.netteGMap.js',
            'www/js/main.js'
        ],
        dest: 'www/js/compiled.min.js'
    }
},
cssmin: {
    target: {
        files: {
            'www/css/main.min.css': ['www/css/main.css','vendor/venca-x/nettegmap/client/css/netteGMap.css']
        }
    }
}

Simple usage viewer marker

This example show how to view map with marker:

protected function createComponentNetteGMapSimpleViewer() {
    $markers = array();
    $markers[] = new \Marker("home", "description", "49.1695254488", "14.2521617334");
    
    //$netteGMapViewer->setCenterMap(new \GpsPoint(49.1695254488,14.2521617334));
    //$netteGMapViewer->setScrollWheel(true);
    //$netteGMapViewer->setZoom(12);
    //$netteGMapViewer->setMapId('YOUR_GOOGLE_MAP_ID'); // volitelné, viz verze 1.4
    $netteGMapViewer = new \NetteGMapViewer($markers);
          
    return $netteGMapViewer;
}

{control netteGMapSimpleViewer}

Usage viewer marker with polyline

This example show how to show map with marker:

protected function createComponentNetteGMapViewerPolyline() {
    $markers = array();
    $markers[] = new \Marker("home", "description", "49.1695254488", "14.2521617334");
    
    //$netteGMapViewer->setCenterMap(new \GpsPoint(49.1695254488,14.2521617334));
    //$netteGMapViewer->setScrollwheel(TRUE);
    //$netteGMapViewer->setZoom(12);
    $netteGMapViewer = new \NetteGMapViewer($markers);    
    
    //add polyline to map
    $coordinates = array(
        new \GpsPoint(49.169669, 14.252152),
        new \GpsPoint(49.169399, 14.252175),
        new \GpsPoint(49.169532, 14.251842),
        new \GpsPoint(49.169669, 14.252152)
    );
    $polyLine = new \PolyLine($coordinates);
    $netteGMapViewer->setPolyLine($polyLine);
          
    return $netteGMapViewer;
}

{control netteGMapViewerPolyline}

Usage picker in form

This example show how to set GPS position on map:

protected function createComponentGMapForm() {

    $form = new Nette\Application\UI\Form;
    
    $form->addGMap('position', 'Position:')
        ->setWidth("500")
        ->setHeight("500");
        //->showMyActualPositionButton();
        //->setScrollwheel(TRUE);
    
    $form->addSubmit('send', 'Save');
    
    $form->onSuccess[] = [$this, 'gMapFormSucceeded'];
    return $form;
}

public function gMapFormSucceeded($form) {
    $values = $form->getValues();
    
    dump($values);
    exit();
}

Set default position value for picker:

$form->setDefaults(array(
    'position' => array(
        'latitude' => "49.1695254488",
        'longitude' => "14.2521617334",
    ),
));

Latte:

{control gMapForm}

After send form:

Nette\ArrayHash #f110
    position => array (2)
        latitude => "50.0923932109" (13)
        longitude => "14.4580078125" (13)

Usage layer

This example show how to add own picture on map as a new layer:

protected function createComponentNetteGMapLayer() {
    $netteGMapViewer = new \NetteGMapLayer();
    //$netteGMapViewer->setCenterMap(new \GpsPoint("48.977153", "14.454486"));
    $netteGMapViewer->setHeight("600px");
    $netteGMapViewer->setScrollwheel(TRUE);
    $netteGMapViewer->setZoom(18);
    
    $netteGMapViewer->setLayerUrlImage("http://www.barcampjc.cz/pictures/parkoviste.jpg");
    
    $netteGMapViewer->setLayerLeftDownCorner(new \GpsPoint(48.97685376928403, 14.453693823169715));
    $netteGMapViewer->setLayerRightTopCorner(new \GpsPoint(48.97771464665134, 14.45583921230309));
    
    return $netteGMapViewer;
}

Latte:

{control netteGMapLayer}

Callback after change position marker in main.js

When you want call your code after marker position chaged, you can be inspired by this code. main.js

$( function() {
    $( 'body' ).netteGMapPicker( {
    
        //my callback marker change position
        changePositionMarker: function( results ) {    
            var district = results[4].formatted_address.split(",");
            //alert( district[0] );
            $("select#frm-addCompetitionForm-district_id option").each(function() { this.selected = ( this.text === district[0] ); });
            $("select#frm-editCompetitionForm-district_id option").each(function() { this.selected = ( this.text === district[0] ); });
            //alert('changePositionMarker');
        }
    
    } );
} );
