Supported Maps

Map Picker currently supports the following map:

1. Open Street Map (OSM)

Additional map options will be added to the package as needed and tested.

Installation

You can easily install the package via Composer:

composer require dotswan/filament-map-picker

Basic Usage

Resource file:

<?php
namespace App\Filament\Resources;
use Filament\Resources\Resource;
use Filament\Resources\Forms\Form;
use Dotswan\MapPicker\Fields\Map;
...

class FilamentResource extends Resource
{
    ...
    public static function form(Form $form)
    {
        return $form->schema([
            Map::make('location')
                        ->label('Location')
                        ->columnSpanFull()
                        ->defaultLocation(latitude: 40.4168, longitude: -3.7038)
                        ->afterStateUpdated(function (Set $set, ?array $state): void {
                            $set('latitude',  $state['lat']);
                            $set('longitude', $state['lng']);
                            $set('geojson',   json_encode($state['geojson']));
                        })
                        ->afterStateHydrated(function ($state, $record, Set $set): void {
                            $set('location', [
                                    'lat'     => $record->latitude, 
                                    'lng'     => $record->longitude,
                                    'geojson' => json_decode(strip_tags($record->description))
                                ]
                            );
                        })
                        ->extraStyles([
                            'min-height: 150vh',
                            'border-radius: 50px'
                        ])
                        ->liveLocation(true, true, 5000)
                        ->showMarker()
                        ->markerColor("#22c55eff")
                        ->showFullscreenControl()
                        ->showZoomControl()
                        ->draggable()
                        ->tilesUrl("https://tile.openstreetmap.de/{z}/{x}/{y}.png")
                        ->zoom(15)
                        ->detectRetina()
                        ->showMyLocationButton()
                        ->geoMan(true)
                        ->geoManEditable(true)
                        ->geoManPosition('topleft')
                        ->drawCircleMarker()
                        ->rotateMode()
                        ->drawMarker()
                        ->drawPolygon()
                        ->drawPolyline()
                        ->drawCircle()
                        ->dragMode()
                        ->cutPolygon()
                        ->editPolygon()
                        ->deleteLayer()
                        ->setColor('#3388ff')
                        ->setFilledColor('#cad9ec')
           ]);
    }
    ...
}

If you wish to update the map location and marker either through an action or after altering other input values, you can trigger a refresh of the map using the following approach:

use Filament\Forms\Components\Actions\Action;
use Filament\Forms\Components\Actions;
use Filament\Support\Enums\VerticalAlignment;

Actions::make([
    Action::make('Set Default Location')
        ->icon('heroicon-m-map-pin')
        ->action(function (Set $set, $state, $livewire): void {
            $set('location', ['lat' => '52.35510989541003', 'lng' => '4.883422851562501']);
            $set('latitude', '52.35510989541003');
            $set('longitude', '4.883422851562501');
            $livewire->dispatch('refreshMap');
        })
])->verticalAlignment(VerticalAlignment::Start);

liveLocation Option

The liveLocation method accepts three parameters:

1. bool $send: Determines if the user's live location should be sent.
2. bool $realtime: Controls whether the live location should be sent to the server periodically.
3. int $milliseconds: Sets the interval (in milliseconds) at which the user's location is updated and sent to the server.

Example:

Map::make('location')
    ->liveLocation(true, true, 10000)  // Updates live location every 10 seconds
    ->showMarker()
    ->draggable()

Options Table

Here's a table describing all available options and their default values:

Usage As Infolist Field

The MapEntry Infolist field displays a map.

use Dotswan\MapPicker\Infolists\MapEntry;

    public static function infolist(Infolist $infolist): Infolist
    {
        return $infolist
            ->schema([
                MapEntry::make('location')
                    ->extraStyles([
                        'min-height: 50vh',
                        'border-radius: 50px'
                    ])
                    ->state(fn ($record) => ['lat' => $record?->latitude, 'lng' => $record?->longitude])
                    ->showMarker()
                    ->markerColor("#22c55eff")
                    ->showFullscreenControl()
                    ->draggable(false)
                    ->zoom(15),

                .....
            ]);
    }

Usage Guide for Handling Map Locations

This section explains how to handle and display map locations within your application using this package.

Step 1: Define Your Database Schema

Ensure your database table includes latitude and longitude columns. This is essential for storing the coordinates of your locations. You can define your table schema as follows:

$table->double('latitude')->nullable();
$table->double('longitude')->nullable();

Step 2: Retrieve and Set Coordinates

When loading a record, ensure you correctly retrieve and set the latitude and longitude values. Use the following method within your form component:

->afterStateHydrated(function ($state, $record, Set $set): void {
    $set('location', ['lat' => $record?->latitude, 'lng' => $record?->longitude]);
})

Step 3: Add Form Fields for Latitude and Longitude

Add hidden form fields for latitude and longitude to your form. This ensures the values are present but not visible to the user:

TextInput::make('latitude')
    ->hiddenLabel()
    ->hidden(),

TextInput::make('longitude')
    ->hiddenLabel()
    ->hidden()

If you prefer to display these values in a read-only format, replace hidden() with readOnly().

Alternative Approach: Using a Single Location Attribute

If you prefer to handle the location as a single field, you can define a custom attribute in your model. This method avoids the need for separate latitude and longitude columns:

class YourModel extends Model
{
    protected function location(): Attribute
    {
        return Attribute::make(
            get: fn (mixed $value, array $attributes) => [
                'latitude' => $attributes['latitude'],
                'longitude' => $attributes['longitude']
            ],
            set: fn (array $value) => [
                'latitude' => $value['latitude'],
                'longitude' => $value['longitude']
            ],
        );
    }
}

This approach encapsulates both latitude and longitude within a single location attribute, streamlining your code.
