  $ps = DB::table('ps')->get();
  return view('viewps', ['ps' => $ps]);
  }

  public function view($id){
  $ps = Ps::find($id)

  $ps_id = DB::table('product')->get();
  return view('sellitem', ['ps_id' => $ps_id,'id'=>$id]);
  }

    @if ($ps_id == $id)
        <div class="searchable-container">

Route::get('/viewps', 'PsController@show');
Route::get('/viewps/{id}', 'PsController@view')->name('view');
Route::get('/home', 'HomeController@index')->name('home');
