Filament Multisite

Manage multiple sites within a single Laravel application with first‑class Filament integration.

The package provides:

• Multi‑site routing (domains / prefixes / locales)
• Localized routes and helpers for URL generation
• Per‑site models via HasMultisite
• Filament admin integration with site switching

---

Requirements

• PHP 8.4+
• Laravel 12+
• Filament 4+ (for admin panel integration)

---

Installation

1. Install the package

   composer require zoker/filament-multisite

2. Publish and run migrations

   php artisan vendor:publish --tag=filament-multisite-migrations
   php artisan migrate

3. Register the Filament plugin

   In your Filament panel configuration:

   use Zoker\FilamentMultisite\Multisite;
   
   // In your Filament panel definition
   ->plugin(Multisite::make())

---

Frontend usage

Defining multisite routes

Create site‑specific routes in routes/web.php using the multisite macro:

use Illuminate\Support\Facades\Route;

Route::multisite(function () {
    // These routes will be available for all sites
    Route::get('/', [HomeController::class, 'index'])->name('home');

    // Add more site‑specific routes here
});

Translatable routes

Use the translatable macro for localized paths. Translation keys should be placed in your application's resources/lang directory:

Route::translatable(function () {
    Route::get(__('routes.about'), [AboutController::class, 'index'])->name('about');
});

Generating URLs

Use the multisite_route() helper to generate URLs that respect the current site and locale:

// Basic usage
$url = multisite_route('home');

// With parameters
$url = multisite_route('products.show', ['product' => $product]);

// Absolute URLs
$url = multisite_route('login', [], true);

---

Managing the current site (frontend)

Facade: SiteManager

use Zoker\FilamentMultisite\Facades\SiteManager;

// Get current site
$currentSite = SiteManager::getCurrentSite();

// Set current site by ID
SiteManager::setCurrentSiteById(1);

// Set current site by request
SiteManager::setCurrentSiteByRequest($request);

Helper: currentSite()

// Get current site
$site = currentSite();

Middleware

Use middleware to automatically resolve the current site from the request:

use Illuminate\Support\Facades\Route;
use Zoker\FilamentMultisite\Http\Middleware\MultisiteMiddleware;

Route::middleware([MultisiteMiddleware::class])->group(function () {
    // Your routes here
});

You can also register the middleware in the web group.

Filament integration

Site switching in Filament

In Filament the active site is managed via the FilamentSiteManager. The currently selected site is stored in the session and is used automatically by models with the HasMultisite trait when Filament is serving the request.

Add the SiteSwitcher action to your Filament resources:

use Zoker\FilamentMultisite\Filament\Actions\SiteSwitcher;

public function getActions(): array
{
    return [
        SiteSwitcher::make(),
    ];
}

Translatable models

To use translatable models, add the HasTranslations trait to your model and define the translatable attributes.
These attributes must be stored in JSON columns in your database.

use Illuminate\Database\Eloquent\Model;
use Spatie\Translatable\HasTranslations;

class YourModel extends Model
{
    use HasTranslations;

    /** @var array<int, string> */
    public array $translatable = ['attribute'];
}

## Per‑site models: `HasMultisite`

To store separate content per site, add the `HasMultisite` trait to your model:

```php
use Illuminate\Database\Eloquent\Model;
use Zoker\FilamentMultisite\Traits\HasMultisite;

class YourModel extends Model
{
    use HasMultisite;
}

This trait adds a global scope on the site_id column:

• In frontend/HTTP context the current site is resolved via SiteManager.
• In Filament context the current site is resolved via FilamentSiteManager (selected site in the admin panel).

The trait also provides helpers like createForCurrentSite() to create records for the active site.

Filament resources: HasMultisiteResource

To make a Filament resource aware of the active site, use the HasMultisiteResource trait:

use Filament\Resources\Resource;
use Zoker\FilamentMultisite\Traits\HasMultisiteResource;

class YourResource extends Resource
{
    use HasMultisiteResource;
}

---

Translatable resource traits

For translatable Filament resources you can use:

• Zoker\FilamentMultisite\Traits\Translatable\Resources\Pages\TranslatableEditRecord – for Resource/Pages/Edit*
• Zoker\FilamentMultisite\Traits\Translatable\Resources\Pages\TranslatableListRecord – for Resource/Pages/List*
• Zoker\FilamentMultisite\Traits\Translatable\Resources\Pages\TranslatableCreateRecord – for Resource/Pages/Create*

---

Migrations

To link your models to a specific site, add a foreign key to the sites table:

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
use Zoker\FilamentMultisite\Models\Site;

Schema::table('your_table', function (Blueprint $table) {
    $table->foreignIdFor(Site::class)->constrained()->cascadeOnDelete();
});

---

Alternate Links & Canonical URLs

The package provides automatic generation of alternate links and canonical URLs for SEO optimization.

Frontend Components

Alternate Links Head

Include alternate links in your HTML head section:

<x-multisite::alternateLinksHead />

This will generate:

• <link rel="canonical"> for the specified canonical site (if configured)
• <link rel="alternate" hreflang="..."> for all available sites

Site Picker

Display a site/language switcher component:

<x-multisite::sitePicker />

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=multisite-config

Set up the canonical site in config/multisite.php:

<?php

return [
    'canonical_site_id' => 1, // ID of the site to use as canonical
];

If canonical_site_id = null is not set, canonical link will not be generated

Programmatic Usage

Setting Alternate Links

use Zoker\FilamentMultisite\Services\AlternateLinks;

// Set alternate links in your controller
public function show(Category $category)
{
    $links = [];
    foreach ($sites as $site) {
        $links[] = [
            'site' => $site,
            'url' => localized_url_for_site($site),
        ];
    }
    AlternateLinks::set($links);
    
    return view('category.show', compact('category'));
}

Custom Canonical URL

// Set a custom canonical URL (overrides config)
AlternateLinks::setCanonicalUrl('https://example.com/custom-url');

// Get the current canonical URL
$canonicalUrl = AlternateLinks::getCanonicalUrl();

---

Events

The package dispatches events that you can listen for:

• Zoker\FilamentMultisite\Events\SiteChanged – dispatched when the active site changes.

---

Testing

Run the tests with:

composer test
