Laravel形模型

Question

我form.blade.php就像

<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Edit.blade.php某事象

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

這我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); 
}  

這是當我想編輯產品時，輸入請求被設置爲空！ 例如，當我去http://myLarave/Public/product/2/edit的title和其他投入是空的:( 什麼建議？

Answer 1

在你route.php或web.php取決於你laravel的版本，可以使ARG {id?}，例如：

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

和編輯功能，您可以初始化變量的$ id = null或空：

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); 
    } 
}
