Laravel Macro for Query Filters

// AppServiceProvider@boot
Builder::macro("filters", function (array $allowed, Request $request) {
    foreach ($allowed as $field) {
        if ($request->filled($field)) {
            $this->where($field, $request->input($field));
        }
    }
    return $this;
});

// Usage in controller
Module::query()
    ->filters(["category_slug", "level", "language"], $request)
    ->published()
    ->paginate(12);
