Before logging hook

You can register global callbacks that run on every activity right before it is saved. This is useful for enriching activities with extra data without creating a custom Activity model.

##Registering a callback

Call beforeLogging on the Activity facade, typically in a service provider's boot method:

use Spatie\Activitylog\Facades\Activity;

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        Activity::beforeLogging(function (\Spatie\Activitylog\Contracts\Activity $activity) {
            $activity->properties = $activity->properties->put('ip', request()->ip());
        });
    }
}

Every activity (both manual activity()->log() calls and automatic model event logging) will now include the IP address in its properties.

##Multiple callbacks

You can register multiple callbacks. They run in the order they were registered:

Activity::beforeLogging(function ($activity) {
    $activity->properties = $activity->properties->put('ip', request()->ip());
});

Activity::beforeLogging(function ($activity) {
    $activity->properties = $activity->properties->put('user_agent', request()->userAgent());
});

##Example: batch UUID

If you need to group related activities together (for example, all activities from a single request), you can use the hook to assign a shared identifier:

1. Add the column:

Schema::table('activity_log', function (Blueprint $table) {
    $table->uuid('batch_uuid')->nullable()->index();
});

2. Register the hook:

use Illuminate\Support\Str;
use Spatie\Activitylog\Facades\Activity;

// In your AppServiceProvider::boot()
$batchUuid = (string) Str::uuid();

Activity::beforeLogging(function ($activity) use ($batchUuid) {
    $activity->batch_uuid = $batchUuid;
});

All activities logged during the request will share the same batch_uuid.
