Introduce space class elements into the controller:
use think\File; use app\admin\model\Pic as PicModel;//防止类名字重复报错,起一个别名
Then instantiate it in the method, and then call the method:
public function del() { $id=input('id');//返回的结果为获取的id $lunbotu=db('lunbotu')->find($id);//获取一条数据,这里可以dump()数据,返回结果为数组,访问数组中文件的存放信息的字段,这里是Pic $path='../public/static/uploads/'.$lunbotu['Pic'];//定义文件存放的路径 $unlink=new PicModel();//实例化 if($unlink->unlink($path) && db('lunbotu')->delete(input('id'))) { return redirect('pic');//重定向到你想要的界面 } else { $this->error('删除轮播图失败'); } }
