Laravel表单模型

Question

My form.blade.php is sth like

<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>    `

and my Edit.blade.php is like

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

And this my 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);
}     

this is while when i wanna edit a product, the input requests are set empty!! for instance when i go to http://myLarave/Public/product/2/edit the title and other inputs are empty :( any suggestions?!

Answer 1

In your route.php or web.php depend to the version of your laravel, you can make the arg {id?}, for example:

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

and in the edit function you can initialize the variable $id=null or 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);
     }
}
