我不知道将表单文本留空的方法是没有结果。我需要这样的东西......

如果没有userCreator =表单文本为空

我的代码

<div class="col-md-4">
    <div class="form-group">
        {{ Form::label('userCreator','UserCreator') }}
        @if(isset($userCreator))
        @foreach($userCreator as $cs)
        {{ Form::text('userCreator',$cs->home_lastname,['class'=>'form-control']) }}
        @endforeach
        @else{ {{-- What should i put inside here ? --}}
        }
        @endif
    </div>
</div>

Answer 1

@if(isset($userCreator) && count($userCreator) > 0)
    <div class="col-md-4">
        <div class="form-group">
            {{ Form::label('userCreator','UserCreator') }}
            @foreach($userCreator as $cs)
            {{ Form::text('userCreator',$cs->home_lastname,['class'=>'form-control']) }}
            @endforeach

        {{ Form::label('userCreator','UserCreator') }}
        @if(!empty($userCreator))
          @foreach($userCreator as $cs)
            {{ Form::text('userCreator',$cs->home_lastname,['class'=>'form-control']) }}
          @endforeach
        @else
            {{ Form::text('userCreator','', ['class'=>'form-control']) }}
