Question

我的form.blade.php似乎

<div class="form-group">
    {!! Form::label('title', 'title :', ['class' => 'awesome']) !!}
    {!! Form::text('product[title]', null, ['class' => 'form-control']) !!}
</div>

<div class="form-group">
{!! Form::label('description', 'description : ', ['class' => 'awesome']) !!}
{!! Form::text('product[description]', null, ['class' => 'form-control']) !!}

<div id="phone" class="form-group">
    {!! Form::label('reference_id1', 'reference_id1 : ', ['class' =>    'awesome']) !!}
    {!! Form::text('product[reference_id1]', null, ['class' => 'form-     control']) !!}
</div>

  <div class="form-group">
       {!! Form::label('category_id', 'category_id : ', ['class' => 'awesome'])    !!}
        {!! Form::select('category[]', $categories,null, ['class' =>      'form-       control', 'multiple']) !!}
    </div>
<div class="form-group">
    {!! Form::label('color', 'color : ', ['class' => 'awesome']) !!}
    {!! Form::text('feature[0][color]', null, ['class' => 'form-control']) !!}
</div>
<div class="form-group">
    {!! Form::label('height', 'height : ', ['class' => 'awesome']) !!}
    {!! Form::text('feature[0][height]', null, ['class' => 'form-control']) !!}
</div>    `

和我的Edit.blade.php就像

{!! Form::model($product,['method' => 'PATCH', 'action' => ['ProductController@update',$product->id]]) !!}
    @include('products.form', ['submitBtn' => 'submit'])
{!! Form::close() !!}

这是我的ProductController.php@edit

    public function edit($id)
        {
        $product = Product::with('feature')->findOrFail($id);
        $categories = Category::pluck('title','id');
        return view('products.edit')->withProduct($product)->withCategories($categories);
}

这是当我想编辑产品时，输入请求被设置为空！例如，当我转到http://myLarave/Public/product/2/edit title时，其他输入为空:( 有什么建议吗？！

在您的route.php或web.php中依赖于您的laravel的版本，您可以制作arg {id?}，例如：

Route::get('edit/{id?}', 'ProductController@edit');

在编辑功能中，您可以初始化变量$ id = null或empty：

public function edit($id = null)
{
     if($id != null){
        $product = Product::with('feature')->findOrFail($id);
        $categories = Category::pluck('title','id');
        return view('products.edit')->withProduct($product)->withCategories($categories);
     }
}
