How to update and delete comments from database? - php

Question

First of all, I want to save comments after editing.I'm able to save the other features, but now I need to save comments too because they are in other table.
Here is my code for comments:
#foreach($event_comm as $comm)
<div class="row">
<div class="col-md-4">
<label class="label" style="color: black">Comment by {{$comm->user->username}}</label>
<label class="input">
{{ Form::text('comments', $comm->comments) }}
</label>
#endforeach
My update function
public function update($type, $id)
{
/* print_r(Input::all()); die; */
if($type == "Opinion")
{
$article = \App\Opinion::find($id);
$article->subject = Request::input('subject');
$article->public = Request::input('public');
$article->category_id = Request::input('category_id');
$article->opinion = Request::input('opinion');
$article->update();
}
if($type == "Event")
{
$event_comm = EventComment::where('event_id', $id)->get();
$article = \App\Event::find($id);
$article->subject = Request::input('subject');
$event_comm->comments = Request::input('comments');
$article->public = Request::input('public');
$article->category_id = Request::input('category_id');
$article->website = Request::input('website');
$article->email = Request::input('email');
$article->telephone = Request::input('telephone');
$article->information = Request::input('information');
$article->update();
}
return redirect(URL::previous())
->with(compact('event_comm'));
}
I've already tried to add $event_comm->comments = Request::input('comments'); but doesn't work.
2.Second problem.I want to also delete comments from database with a button or something like that.I found a route but I'm not sure if works.I need to know how to add this into my file?With a button ?
My route
Route::get('admin/article/deleteComment/{type}/{id}',['as' => 'deleteComment', 'uses' => 'ArticleController#deleteComment']);
public function deleteComment($type, $id)
{
if($type == "Event")
{
$comment = \App\EventComment::find($id);
}
if($type == "Opinion")
{
$comment = \App\OpinionComment::find($id);
}
$comment->delete();
return redirect('admin/comments');
}
Button:
<button href="{{ url('deleteComment',$type, $id) }}" role="button" class="btn btn-xs btn-danger" onclick="return confirm('Are you sure you want to delete this comment?');">Delete <i class="fa fa-trash"></i></button>
