Laravel 5 字段在laravel5中不更新

我正在使用图像更新进行Laravel表单数据更新。现在，我的图像只能在数据库中顺利更新。但其他字段不更新。谁都知道我的错误是什么？我在下面附上了我的代码：

控制器

    public function siteadmin_update_ads(Request $request)
    {


       $post = $request->all(); 
        $cid=$post['id'];  
        $name = $post['ads_title'];
        $url = $post['ads_url'];
        $img=Input::file('ads_image');;

        $v=validator::make($request->all(),
                [
                    'ads_title'=>'required',
                    'ads_url' => 'required',
                    'ads_image'=> 'required'
                ]
                );

        if($v->fails())
        {
            return redirect()->back()->withErrors($v->errors());
        }



        else 

            {
            if($img->isvalid())
            {
                $extension=$img->getClientOriginalName();
                $move_img = explode('.',$extension);
                $fileName=$move_img[0].str_random(8).".".$move_img[1];
                $destinationPath = '../assets/adsimage/';



                $uploadSuccess=Input::file('ads_image')->move($destinationPath,$fileName);

            $data=array(

                'ads_title'=> $name,
                'ads_url'=>   $url,
                'ads_image'=>$fileName,

            );

            $i=Ads_model::update_ads($data,$cid);

            if($i>0)
            {
                Session::flash ('message_update', 'Record Updated Successfully');
                return redirect('siteadmin_manageads');
            }
        }

             else {
 return Redirect('siteadmin_editads');
}   
}
}

您试过查看laravel.log吗？没有。如何查看laravel.log？它位于storage/logs/laravel.log上

public static function update_ads($data,$cid)
    {
      return DB::table('le_ads')->where('id',$cid)->update($data);  
    }
