Laravel Form Model - php

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);
}
}
