1、将文件上传至指定目录  
2、获取文件的字段与路径  
3、保存文件路径（尽量使用相对路径保存）

upload.php控制器

<?php
    namespace app\goods\controller;
    
    use library\Controller;
    use think\facade\Request;
    use app\goods\logic\UploadLogic;
    /**
     * 文件上传  文件类型验证器
     * Class Upload
     * @package app\goods\controller
     */
    class Upload extends Controller
    {
        //文件上传，将文件报存在指定位置的同时,将文件地址获取并保存链接地址
        public function index()
        {
            $data = 1111111111;
            $this->assign('data', $data);
            $this->fetch('upload/index');
    //        return view('upload/index');
        }
    
        public function file()
        {
           $uploadLogic =  new UploadLogic();
            //获取POST提交的数据信息  存入文件绝对路径
            $postData = Request::post();
            //处理保存图片路径信息
            $res = $uploadLogic->doSaveImg($postData);
            halt($res);
        }
    }

uploadLogin.php逻辑处理类

<?php
    namespace app\goods\logic;
    
    use library\Controller;
    use  think\Db;
    use think\Exception;
    
    class UploadLogic extends Controller
    {
        public function doSaveImg($postData)
        {
            Db::startTrans();
            try {
                //整合数据字段
               $data = $this->initializeFile($postData);
                Db::name('upload_file')->insert($data);
                Db::commit();
                return ['code' => 1, 'msg' => '流程数据添加成功'];
            } catch (Exception $e) {
                Db::rollback();
                return ['code' => 0, 'msg' => '数据库操作异常', 'data' => ['error_msg' => $e->getMessage()]];
            }
        }
    
        public function initializeFile($postData)
        {
            $group = [
                'imgurl'=> $postData['file-field']?? "",
            ];
            return $group;
        }
    }

前端页面代码index.html

{extend name='admin@main'}
    
    {block name="button"}
    {/block}
    
    {block name="content"}
    <form  method="post" class='layui-form' action="{:url('upload/file')}" enctype="multipart/form-data">
       
    
        <input name='file-field'>
        <button type='button' data-file='one' data-field='file-field' data-type='jpg,png,gif'>上传文件</button>
    
        <button type="submit" class="layui-btn" >提交</button>
    </form>
    {/block}
    
    {block name="script"}
    <script>
        window.form.render();
    </script>
    {/block}
