I recently migrated my Laravel project to PHP 8.1, and I’m encountering an issue with dependency injection in my controllers. I have set up auto-injection in my AppServiceProvider using the bind method, but I’m getting a “Too few arguments” error in my controller methods.
Here’s the relevant part of my AppServiceProvider:
use AppRepositoriesTenantRepository;
use AppRepositoriesAdministrationRepository;
use AppRepositoriesTenantRepositoryInterface;
use AppRepositoriesAdministrationRepositoryInterface;
class AppServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->bind(TenantRepositoryInterface::class, TenantRepository::class);
$this->app->bind(AdministrationRepositoryInterface::class, AdministrationRepository::class);
}
}
And here’s a sample controller method:
use AppRepositoriesTenantRepositoryInterface;
use AppRepositoriesAdministrationRepositoryInterface;
class [ControllerName] extends Controller
{
public function tenantListe($message = "", $niveauMessage = "", TenantRepositoryInterface $interface)
{
// Method implementation...
}
// Other controller methods...
}
I have multiple controller methods, each using a different repository interface. Before the migration, this setup was working fine.
How can I resolve this “Too few arguments” error and properly set up dependency injection in my Laravel controller methods after migrating to PHP 8.1?
After encountering the “Too few arguments” issue in my Laravel controllers post-migration to PHP 8.1, I tried reorganizing the parameters by placing TenantRepositoryInterface $interface as the first parameter in the method signature. For example:
public function tenantListe(TenantRepositoryInterface $interface, $message = "", $niveauMessage = "")
This adjustment resolved the problem for this specific method. However, considering the large number of methods in my project, manually reorganizing each method is not a scalable solution.
Is there a more efficient and automated way to address this issue across all my controller methods, considering the recent migration to PHP 8.1?
