Laravel 4错误:未定义的变量

I have made a list query that populates my drop down box. I have tried var_dump on the controllers part and it all went well, but whenever I tried to call my function on my blade template, it would return me an error: Undefined variable: categories (View: C:\wamp\www\airlines\app\views\content\onewayflight.blade.php)

What seems to be the problem here?

OnewayflightController.php

   public function onewayflight()
{ 
  $categories = DB::table('oneways')->lists('destination-from');
  return View::make('content.onewayflight')->with('destination-from', $categories);
}

onewayflight.blade.php

{{ Form::select('destination-from', $categories) }}

routes.php

Route::get('flight/onewayflight','OnewayflightController@onewayflight');

    You should use in Blade:

    {{ Form::select('destination-from', $destination-from) }}
    

    because in your method you used:

    with('destination-from', $categories)
    

    so you told that in Blade $categories have to be named $destination-from

    However you cannot use - in variable name, so you should probably change it into:

    with('destinationFrom', $categories)
    

    and in Blade:

    {{ Form::select('destination-from', $destinationFrom) }}
