Question

How can I add a property type array in Laravel livewire,

Here is blade file :

             @foreach (config('translatable.locales') as $locale => $key)
                        <div class="col-md-6">

                            <div class="form-group">

                                <label> {{ trans('site.' . $key . '.service_title') }} </label>

                                <input type="text" wire:model="{{ $key }}[service_title]"
                                    class="form-control {{ $errors->has($key . '.service_title') ? 'is-invalid' : '' }} "
                                    name="{{ $key }}[service_title]"
                                    placeholder="{{ trans('site.' . $key . '.service_title') }}">

                            </div>

                        </div>
                        @endforeach

Component :

public $ar = ['service_title' , 'service_description'];
public $en = ['service_title' , 'service_description'];




public function store(ServiceRequest $request)
{

    $data =  $this->validate($request->rules);

    Service::create($data);

    session()->flash('success', trans('site.msg_added_successfully'));
}

}

The error when I write on service title input

Thanks
