Integrating a location picker into your Laravel 12 application can significantly enhance user experience, especially for apps that rely on geolocation data. The Google Maps API offers powerful tools to embed interactive maps, pinpoint locations, and capture precise coordinates. This guide will walk you through a step-by-step process to implement a seamless location picker in Laravel 12, complete with real code examples and best practices.
Preparing Your Laravel 12 Project
Before integrating the Google Maps API, ensure your Laravel 12 environment is properly set up. If you are starting fresh, use Composer to create a new project:
composer create-project laravel/laravel laravel-google-maps "^12.0"Navigate into your project directory and set up your database connection in the .env file to store location data if needed.
It’s also beneficial to understand how Laravel compares to other CMS or frameworks like WordPress for your project needs. For those still deciding on their tech stack, our detailed analysis on Laravel vs WordPress can provide valuable insights and help you make an informed decision.
Setting Up Google Maps API
To use Google Maps, you need to obtain an API key:
- Go to the Google Cloud Console and create a new project or select an existing one.
- Navigate to "APIs & Services" > "Credentials" and click "Create Credentials" > "API key".
- Enable the following APIs for your project:
- Maps JavaScript API
- Places API (optional, for autocomplete)
- Geocoding API (optional, for converting addresses)
- Restrict your API key to your domain or IP addresses for security.
Keep your API key secure and do not expose it unnecessarily on the frontend.
Frontend Integration: Embedding the Location Picker
Start by creating a simple Blade view that will render the Google Map with a draggable marker for selecting locations.
Create a new route and controller method to serve this view:
Route::get('/location-picker', [LocationController::class, 'showPicker']);In LocationController.php:
public function showPicker()
{
return view('location-picker');
}Now, in resources/views/location-picker.blade.php, add the following HTML and JavaScript:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Location Picker</title>
<style>
#map {
height: 400px;
width: 100%;
}
</style>
</head>
<body>
<h2>Pick Your Location</h2>
<div id="map"></div>
<form method="POST" action="{{ route('location.save') }}">
@csrf
<input type="hidden" id="latitude" name="latitude">
<input type="hidden" id="longitude" name="longitude">
<button type="submit">Save Location</button>
</form>
<script src="https://maps.googleapis.com/maps/api/js?key={{ config('services.google_maps.key') }}"></script>
<script>
let map;
let marker;
function initMap() {
const initialPosition = { lat: -34.397, lng: 150.644 };
map = new google.maps.Map(document.getElementById('map'), {
center: initialPosition,
zoom: 8
});
marker = new google.maps.Marker({
position: initialPosition,
map: map,
draggable: true
});
// Update hidden inputs on marker drag
google.maps.event.addListener(marker, 'dragend', function() {
const pos = marker.getPosition();
document.getElementById('latitude').value = pos.lat();
document.getElementById('longitude').value = pos.lng();
});
// Initialize hidden inputs with default position
document.getElementById('latitude').value = initialPosition.lat;
document.getElementById('longitude').value = initialPosition.lng;
}
window.onload = initMap;
</script>
</body>
</html>This code sets up a Google Map centered on a default location with a draggable marker. The latitude and longitude inputs update dynamically as the marker moves, allowing users to pick their precise location.
Backend Processing: Handling Location Data in Laravel
Create a POST route to handle the form submission and save the location data:
Route::post('/location/save', [LocationController::class, 'saveLocation'])->name('location.save');In LocationController.php, add the following method:
public function saveLocation(Request $request)
{
$request->validate([
'latitude' => 'required|numeric',
'longitude' => 'required|numeric',
]);
// Example: Save to database (assuming you have a Location model)
// Location::create([
// 'latitude' => $request->latitude,
// 'longitude' => $request->longitude,
// ]);
return back()->with('success', 'Location saved successfully!');
}This method validates the latitude and longitude inputs and processes the data accordingly. You can expand this by storing the location in a database or using it to customize user experience.

Best Practices for Google Maps Integration in Laravel
- ✓ Secure your API key: Always restrict your Google Maps API key to specific domains or IPs and avoid exposing it unnecessarily.
- ✓ Use environment variables: Store your API keys in
.envand access them via Laravel’s config files to keep credentials safe. - ✓ Optimize map loading: Load the Google Maps script asynchronously and only when needed to improve page performance.
- ✓ Handle errors gracefully: Add fallback behavior if the Maps API fails to load or if geolocation permissions are denied.
- ✓ Consider user experience: Implement autocomplete for addresses using the Places API to help users input locations faster.
- ✓ Validate coordinates: Always validate and sanitize input on the backend to prevent invalid or harmful data.
By following these best practices, your integration will be more robust and user-friendly.
