Laravel User Timezones – Automatically detect user time zones

To implement automatic timezone detection for users in a Laravel application, you can use JavaScript to detect the user’s timezone and then store it in the user’s profile. This allows you to display date and time information correctly according to the user’s local timezone.

Step 1: Install Required Packages

While you can manage timezones using native PHP features, it’s beneficial to use Carbon (which is included in Laravel) for handling date and time formatting. If you need more advanced timezone handling, consider installing the nesbot/carbon

package:

bash

composer require nesbot/carbon

1	composer require nesbot/carbon

Step 2: Create a Middleware (Optional)

If you want to set the application timezone based on the user’s stored timezone on each request, you can create a middleware. Run the following command to create a new middleware:

bash

php artisan make:middleware SetTimezon

1	php artisan make:middleware SetTimezon

In the newly created middleware (app/Http/Middleware/SetTimezone.php), you can define the logic to set the application timezone:

php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class SetTimezone
{
    public function handle($request, Closure $next)
    {
        if (Auth::check()) {
            $timezone = Auth::user()->timezone; // Ensure you have a timezone field in the User model.
            if ($timezone) {
                date_default_timezone_set($timezone);
            }
        }

        return $next($request);
    }
}

<?php

namespace App\Http\Middleware;

use Closure;

use Illuminate\Support\Facades\Auth;

class SetTimezone

{

public function handle($request, Closure $next)

{

if (Auth::check()) {

$timezone = Auth::user()->timezone; // Ensure you have a timezone field in the User model.

if ($timezone) {

date_default_timezone_set($timezone);

}

return $next($request);

}

Step 3: Register Middleware

You need to register your middleware in the app/Http/Kernel.php file. Add it to the web middleware group:

php

protected $middlewareGroups = [
    'web' => [
        // other middleware...
        \App\Http\Middleware\SetTimezone::class,
    ],
];

protected $middlewareGroups = [

'web' => [

// other middleware...

\App\Http\Middleware\SetTimezone::class,

];

Step 4: Add Timezone Field to Users Table

Ensure that your users table has a timezone column. You can create a migration to add this column:

bash

php artisan make:migration add_timezone_to_users_table --table=users

1	php artisan make:migration add_timezone_to_users_table --table=users

In the migration file, add the following code:

php

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        $table->string('timezone')->nullable(); // Add timezone field
    });
}

public function down()
{
    Schema::table('users', function (Blueprint $table) {
        $table->dropColumn('timezone');
    });
}

public function up()

{

Schema::table('users', function (Blueprint $table) {

$table->string('timezone')->nullable(); // Add timezone field

});

}

public function down()

{

Schema::table('users', function (Blueprint $table) {

$table->dropColumn('timezone');

});

}

Run the migration:

bash

php artisan migrate

1	php artisan migrate

Step 5: Capture User Timezone with JavaScript

You can use JavaScript to detect the user’s timezone and send it to the server. Here’s how you can implement it:

In your Blade view (e.g., resources/views/layouts/app.blade.php), add the following script to capture the timezone:

html

<script>
    document.addEventListener('DOMContentLoaded', function () {
        var timezone = Intl.DateTimeFormat().resolvedOptions().timeZone;

        // Send the timezone to the server using AJAX
        fetch('/set-timezone', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
                'X-CSRF-TOKEN': '{{ csrf_token() }}'
            },
            body: JSON.stringify({ timezone: timezone })
        });
    });
</script>

document.addEventListener('DOMContentLoaded', function () {

var timezone = Intl.DateTimeFormat().resolvedOptions().timeZone;

// Send the timezone to the server using AJAX

fetch('/set-timezone', {

method: 'POST',

headers: {

'Content-Type': 'application/json',

'X-CSRF-TOKEN': '{{ csrf_token() }}'

body: JSON.stringify({ timezone: timezone })

});

</script>

Step 6: Create a Route and Controller Method to Store Timezone

You’ll need a route to handle the AJAX request:

php

use App\Http\Controllers\UserController;

Route::post('/set-timezone', [UserController::class, 'setTimezone']);

use App\Http\Controllers\UserController;

Route::post('/set-timezone', [UserController::class, 'setTimezone']);

In your UserController, add the method to update the user’s timezone:

php

public function setTimezone(Request $request)
{
    $request->validate([
        'timezone' => 'required|string|timezone',
    ]);

    $user = Auth::user();
    $user->timezone = $request->timezone;
    $user->save();

    return response()->json(['message' => 'Timezone updated successfully']);
}

public function setTimezone(Request $request)

{

$request->validate([

'timezone' => 'required|string|timezone',

]);

$user = Auth::user();

$user->timezone = $request->timezone;

$user->save();

return response()->json(['message' => 'Timezone updated successfully']);

}

Step 7: Use Timezone in Your Application

Whenever you need to display dates/times in the user’s timezone, you can use Carbon to convert the time:

php

use Carbon\Carbon;

// Assuming you have a timestamp to format
$dateTime = Carbon::now(); // Or get the time from your model
$userTimezone = Auth::user()->timezone;

$localTime = $dateTime->setTimezone($userTimezone);

echo $localTime->format('Y-m-d H:i:s'); // Display the time in user's timezone

use Carbon\Carbon;

// Assuming you have a timestamp to format

$dateTime = Carbon::now(); // Or get the time from your model

$userTimezone = Auth::user()->timezone;

$localTime = $dateTime->setTimezone($userTimezone);

echo $localTime->format('Y-m-d H:i:s'); // Display the time in user's timezone

Step 8: Testing

Log in to your application.
Check your browser console for the AJAX request to ensure the timezone is sent.
Verify the user’s timezone is stored in the database.
Check the display of dates/times in your application to see if they reflect the user’s timezone.

Summary

With this setup, you’ve successfully implemented automatic timezone detection for users in your Laravel application. Here’s a recap of the steps:

Register the middleware in the kernel.
Add a timezone field to the users table.
Capture the user’s timezone using JavaScript and send it to the server.
