Implementation of uploading files in the controller UploadController.class.php

namespace Home\Controller;
use Think\Controller;
class UploadController extends Controller {
public function index() {
$img=M(&#39;upload_img&#39;);
$sel=$img->order(&#39;create_time desc&#39;)->find();
$this->assign(&#39;data&#39;, $sel);
$this->display();
}
public function upload(){
$upload_img=M(&#39;upload_img&#39;);
if(!empty($_FILES)){
//上传单个图像
$upload = new \Think\Upload();// 实例化上传类
$upload->maxSize = 1*1024*1024 ;// 设置附件上传大小
$upload->exts = array(&#39;jpg&#39;, &#39;gif&#39;, &#39;png&#39;, &#39;jpeg&#39;);// 设置附件上传类型
$upload->rootPath = &#39;Public/Uploads/&#39;; // 设置附件上传根目录
$upload->savePath = &#39;&#39;; // 设置附件上传（子）目录
$upload->saveName=array(&#39;uniqid&#39;,&#39;&#39;);//上传文件的保存规则
$upload->autoSub = true;//自动使用子目录保存上传文件 
$upload->subName = array(&#39;date&#39;,&#39;Ymd&#39;);
// 上传单个图片
$info = $upload->uploadOne($_FILES[&#39;image&#39;]);
if(!$info) {// 上传错误提示错误信息
$this->error($upload->getError());
}else{// 上传成功 获取上传文件信息
$img_url=$info[&#39;savepath&#39;].$info[&#39;savename&#39;];
$data[&#39;img_url&#39;]=$img_url;
$data[&#39;img_name&#39;]=$info[&#39;savename&#39;];
$data[&#39;create_time&#39;]=NOW_TIME;
$upload_img->create($data);
