Answer 1

After review your full question again and again, I found that you have got this error on detele method.
You need to send posts variable also on delete method :
public function showem(Post $post)
{
$posts = Post::get();
return view('users.registered', compact('posts'));
}
public function deleteAll(Request $request)
{
$ids = $request->ids;
$deleted = Post::whereIn('id',explode(",",$ids))->delete();
$posts = Post::get();
return view('users.registered', compact('posts')); // here send the posts variable
}
