unable to delete subcategory with laravel - php

Question

I know it sounds stupid but I've got strange issue with deleting my subcategories, when I try to delete my sub it gives me error that name and slug is required! seems I try to add input in database!
here is some images to make it clear for you:
Here is my controller destroy function:
public function destroy($id)
{
$subcategory = Subcategory::find($id);
$subcategory->delete();
Session::flash('success', 'Your Sub-Category Deleted successfully!');
return redirect()->route('subcategories.index');
}
And this is my form which you see in images above:
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>ID</th>
<th>Subcategory Name</th>
<th>Slug</th>
<th>Parent Category</th>
<th>Operation</th>
</tr>
</thead>
<tbody>
#foreach ($categories as $category)
#foreach($category->subcategories as $sub)
<tr>
<td>{{ $sub->id }}</td>
<td>{{ $sub->name }}</td>
<td>{{ $sub->slug }}</td>
<td>{{ $sub->category->name }}</td>
<td>
Edit
{!! Form::model(['route' => ['subcategories.destroy', $sub->id], 'method' => "DELETE"]) !!}
{{ Form::submit('Delete', ['class' => 'btn btn-sm btn-danger']) }}
{!! Form::close() !!}
</td>
</tr>
#endforeach
#endforeach
</tbody>
</table>

I think it caused the Form::open return:
<form method="DELETE" action="{{route('subcategories.destroy', ['id' => $sub->id])}}">
I think that is the problem, I have same probleme here and I have read about this in Laracast.
So in my case I change not use Form::open(). I use manual form, and my code looked like this:
<form method="POST" action="{{route('subcategories.destroy', ['id' => $sub->id])}}">
{{ method_field('DELETE') }}
.
.
.
</form>
I hope it can help you :)
