📈 Simple UTM tracking middleware for Laravel. Capture UTM parameters from the URL and make them easily accessible via session or helper methods. Great for tracking marketing sources across forms, registrations, or orders.

✨ Features

Middleware to automatically store UTM parameters
Configurable list of UTM keys
Store in session (default) or extend for other storage
Facade for easy access: Utm::get('utm_source')
Trait for auto-filling UTM data directly on Eloquent models
Trait for attaching UTM data to a related model (utmVisit)
Artisan command to generate a migration dynamically

🔧 Installation

composer require webudvikleren/laravel-utm-manager

Publish the config file:

php artisan vendor:publish --tag=config --provider="Webudvikleren\UtmManager\UtmManagerServiceProvider"

🚀 Usage

1. Add middleware

You can register the middleware globally or per route:

// app/Http/Kernel.php
protected $middleware = [
    // ...
    \Webudvikleren\UtmManager\Http\Middleware\CaptureUtmParameters::class,
];

Or assign it to specific routes:

Route::middleware(['utm.capture'])->group(function () {
    Route::get('/register', [RegisterController::class, 'show']);
});

2. Access UTM data

Use the facade to get stored UTM parameters:

use Utm;

Utm::get('utm_source'); // e.g., 'facebook'
Utm::all(); // returns all captured UTM data as array

3. Automatically attach UTM data to Eloquent models

Add the HasUtmData trait to your model:

use Webudvikleren\UtmManager\Traits\HasUtmData;

class Lead extends Model
{
    use HasUtmData;

    protected $fillable = [
        'name', 'email',
        'utm_source', 'utm_medium', 'utm_campaign',
    ];
}

When creating the model, UTM fields will be auto-filled (if present in the session).

4. Store UTM data in a related model

If you want to store UTM data in a separate model (e.g., utm_visits), use the HasUtmRelation trait:

use Webudvikleren\UtmManager\Traits\HasUtmRelation;

class User extends Model
{
    use HasUtmRelation;

    public function utmVisit()
    {
        return $this->hasOne(\App\Models\UtmVisit::class);
    }
}

Then define the related model like this:

class UtmVisit extends Model
{
    protected $table = 'utm_visits'; // or load from config('utm.table')

    protected $fillable = [
        'utm_source',
        'utm_medium',
        'utm_campaign',
        'utm_term',
        'utm_content',
    ];

    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

The related model class and table name are both configurable via config/utm.php.

5. Generate a migration for related UTM data

The package includes an Artisan command to generate a migration based on the configured UTM keys and table name.

php artisan utm:make-migration
php artisan migrate

This will generate a migration with the correct user_id foreign key and all defined UTM columns.

6. Publish the default UtmVisit model

To create a prebuilt UtmVisit model in your app/Models folder:

php artisan utm:publish-model

You can then customize the model or change the class in config/utm.php.

⚙️ Configuration

// config/utm.php

return [

    // Where to store UTM data: 'session' (default)
    'storage' => 'session',

    // Which UTM keys to track
    'utm_keys' => [
        'utm_source',
        'utm_medium',
        'utm_campaign',
        'utm_term',
        'utm_content',
    ],

    // Table name for storing UTM visits (if using HasUtmRelation)
    'table' => 'utm_visits',

    // Fully qualified class name for related UTM model
    'related_model' => \App\Models\UtmVisit::class,
];

📦 Example URL

Send traffic with UTM parameters to your app:

https://yourapp.com/register?utm_source=facebook&utm_medium=social&utm_campaign=summer-sale

The package will capture and store these in the user's session.
