错误“在Laravel中尝试删除行时调用未定义的方法stdClass :: delete()”

My method to delete an image from database and local storage.

public function destroy($id) {
        $image = DB::table('images')->where('id', '=', $id)->first();
        //print_r($image);
        //return 'end';
        File::delete(public_path() . '/images/gallery/thumb-' . $image->path);
        File::delete(public_path() . '/images/gallery/' . $image->path);
        $image->delete();
        return Redirect::back()
                        ->with('form_success', 1)
                        ->with('form_message', 'Image successfully deleted!');
    }

If I try to return value of $image I get:

stdClass Object ( [id] => 49 [site_id] => 1 [page_id] => [location] => gallery [alt] => [path] => 60e52a2755ffe8923d5ac1232f5d9154.jpg ) 

So what's wrong with my code? Now my Laravel version is 4.2.1, but i try to downgrade him to 4.1.17, but no changes.

    Change your code according the following and I hope that your problem will be solved..

    public function destroy($id) {
            $query = DB::table('images')->where('id', '=', $id);
            $image = $query->first();
            //print_r($image);
            //return 'end';
            File::delete(public_path() . '/images/gallery/thumb-' . $image->path);
            File::delete(public_path() . '/images/gallery/' . $image->path);
            $query->delete();
            return Redirect::back()
                            ->with('form_success', 1)
                            ->with('form_message', 'Image successfully deleted!');
        }
    

    first() and delete() these functions execute the code.So first assign your conditions to a variable and then execute them separately.Thanks
