<h2>New Tags</h2>

</div>
My problem is, how to get the id from url which is id '1' and passing into the form when user clicked submit.
My controller
public function store(Request $request,$name)
{
$this->validate($request,array('name'=>'required|max:255'));
$tag=new Tag;
$tag->name=$request->name;
$tag->roundtable_id=$name;
$tag->save();
Session::flash('success','New Tag was successfully added');
return redirect()->route('tags.index');
}

Answer 1

When you're using custom routes for CRUD, avoid using standard RESTful method and route names. Before building the form, you need to pass this variable to the view:
public function createTag($name)
{
....
return view('form', compact('name'));
}
Define your route as:
Route::get('roundtables/{name}/tags/storeTag',['as'=>'tags.storeTag','uses'=>'TagController#storeTag','middleware'=>['owner','auth']]);
Then pass variable to from the form:
{!! Form::open(['route' => ['tags.storeTag', $name], 'method'=>'GET']) !!}
And get it in the controller:
public function storeTag(Request $request, $name)
{
echo $name;

Answer 2

You get the wildcard value by using request() helper method easily.
{{request()->route('name')}}

Answer 3

In your TagController
public function index($name)
{
$tags= Tag::where($name)->first();
// add name parameter to return
return view('tags.index')->withTags($tags)->withName($name);
}
And in your view
<div class="col-md-3">
<div class="well">
//edit this form tag
{!! Form::open(['route'=>['tags.store',$name],'method'=>'GET']) !!}
<h2>New Tags</h2>
{{ Form::label('name','Name') }}
{{ Form::text('name',null,['class'=>'form-control']) }}
{{Form::submit('Create New Tag',['class'=>'btn btn-primary btn-block btn-h1-spacing'])}}
</div>
</div>
And in your TagController#store
public function store(Request $request,$name){
echo $name;
}

Answer 4

This should work.
Request::segment(2)
Or pass it from controller:
public function index($name)
{
$tags= Tag::where($name)->first();
return view('tags.index')->withTags($tags)->with('name', $name);
}
Then just pass it into the form:
{!! Form::open(['route'=>['tags.store', $name],'method'=>'GET']) !!}
