Nova Gmap Field

A Nova field control for using Google Maps to update a latitude/longitude positon.

Installation

Install the package via composer with:

composer require adamcmoore/nova-gmap

Next publish the config file with:

php artisan vendor:publish --provider="Acm\NovaGmap\FieldServiceProvider.php" --tag="config"

This will create a config file at config/nova-gmaps.php where you will need to enter your Google Maps API key, default position and zoom level.

Versions

• v1.0 Laravel 6 & 7
• v2.0 Laravel 8

Usage

To add this field to a Nova resource:

NovaGmap::make('Location')

The field expects data to be provided as an object with keys for latitude and longitude, and will return data from the request in the same format. Use Accessors and Mutators to handle this.

An example model:

class Shop extends Model
{

	$fillable = [
		'title',
		'description',
		'address',
		'location_lat',
		'location_lng',
	];


	/*
	Provide the Location value to the Nova field
	*/
	public function getLocationAttribute()
	{
		return (object) [
			'latitude' => $this->location_lat,
			'longitude' => $this->location_lng,
		];
	}


	/*
	Transform the returned value from the Nova field
	*/
	public function setLocationAttribute($value)
	{
		$location_lat = round(object_get($value, 'latitude'), 7);
		$location_lng = round(object_get($value, 'longitude'), 7);
		$this->attributes['location_lat'] = $location_lat;
		$this->attributes['location_lng'] = $location_lng;
	}
}
