Laravel的create页面和edit页面共用表单，但是edit页面有变量，create页面没有变量，能否共用？

<code><input name="end" value="{{isset($data['end'])?$data['end']:''}}" type="text" id="end_time" placeholder=""></code>

<code><input type="text" name="title" id="title" value="{{ ! empty(old('title')) ? old('title') : (isset($post) ?　$post->title : '') }}"></code>

<code><input type="text" name="title" id="title" value="{{ isset($post) ?　$post->title : '' }}"></code>

<code><input type="text" value="{{$s or ''}}">
</code>

<code>{!! Form::open(['url'=>'article']) !!}
        @include('article._form', ['submitButton'=>'添加文章'])
{!! Form::close() !!}</code>

<code>{!! Form::model($article, ['method'=>'PATCH', 'url'=>['article', $article->id]]) !!}
        @include('article._form', ['submitButton'=> '修改文章'])
{!! Form::close() !!}</code>
