How to delete the database and the files uploaded to the server at the same time in TP5:

The method defined in the model is as follows

<?php

namespace app\admin\model;
use think\Model;

class Pic extends Model
{ 
  
	public function unlink($path)
	{
		return  is_file($path) && unlink($path);
	}

}

Then call yours in the controller method, it is recommended to use absolute path for $path in the controller,

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');
		}
	    }
