Code

Here we can use the if statement before the delete action is done.

We can easily use auth() or Auth::user() to check the authentication. It shows the auth user details and works when the user is logged-in.

So, we will place this in the if statement.

If auth user is equal to the post->user_id, then do this.

if(auth()->user()->id == $thread->user_id){
     $thread->delete();
}
else
{
     abort(401, "unauthorized");
}

Or,

If auth user is not equal to post->user_id, then do this.

        if(auth()->user()->id !== $thread->user_id){
            abort(401, "unauthorized");
        }
