protected function checkDomainLimit(License $license, string $domain): bool laravel license key system

protected function registerActivation(License $license, string $domain, string $ip)

if ($activeDomains >= $license->max_domains) // allow if this domain is already activated return $license->activations()->where('domain', $domain)->exists();

// Attach license info to request for later use $request->attributes->set('license', $result); protected function checkDomainLimit(License $license

namespace App\Services; use App\Models\License; use App\Models\LicenseActivation; use Illuminate\Http\Request;

return true;

$license = License::create([ 'key' => generateLicenseKey('PROD'), 'user_id' => auth()->id(), 'product_name' => 'Pro Plan', 'valid_until' => now()->addYear(), 'max_domains' => 3, 'features' => ['api', 'export'] ]); Create a LicenseService class. string $ip) if ($activeDomains &gt

public function validate(string $key, ?string $domain = null): array

if ($domain && !$this->checkDomainLimit($license, $domain)) return ['valid' => false, 'message' => 'Domain limit exceeded.'];
