Bir üye işlevine çağırın Move() null

Question

Bu sorunu nasıl çözeceğimi anlayamıyorum. Bir img seçmezsem makale sayfamı oluşturmaya çalışırken null hatasıyla başarısız olur. Herhangi bir fikir sahibi olan var mı?

Hata Hata ayıklama modu kullanılarak üretildi. Null'da bir üye işlevine move() çağırın. /home/UNIT3D/app/controllers/Admin/ArticleController.php

$post->image = null; 
    } 

    $v = Validator::make($post->toArray(), $post->rules); 
    if($v->fails()) 
    { 
     // Suppression de l'image car la validation a échoué 
     if(file_exists(Input::file('image')->move(getcwd() . '/files/img/' . $post->image)))  
     { 
      unlink(Input::file('image')->move(getcwd() . '/files/img/' . $post->image));
