Implement upload file in controller UploadController.class.php

namespace Home\controller;
Use Think\controller; Class Uploadcontroller extends Controller {public Function index () {$img =m (' upload_img '); $sel = $img->order (' Create_
Time Desc ')->find ();
$this->assign (' data ', $sel);
$this->display (); Public function upload () {$upload _img=m (' upload_img '); if (!empty ($_files)) {//Upload a single image $upload = new \think\upload (); Example Upload class $upload->maxsize = 1*1024*1024//Set attachment upload size $upload->exts = array (' jpg ', ' gif ', ' PNG ', ' jpeg ');//Set attachment upload type $up Load->rootpath = ' public/uploads/'; Set attachment upload root directory $upload->savepath = '; Set attachment upload (sub) directory $upload->savename=array (' uniqid ', ');//Upload file Save rule $upload = true;//automatically use subdirectories to save uploaded files $
Upload->subname = Array (' Date ', ' Ymd ');
Upload a single picture $info = $upload->uploadone ($_files[' image '); if (! $info) {//Upload error message error messages $this->error ($upload->geterror ());} else{//upload successfully upload file information $img _url= $info [' Savepath ']. $info [' Savename ']; $data [' Img_url ']= $img _url; $data [' Img_name ']=$]
info[' Savename ']; $data [' Create_time']=now_time;
$upload _img->create ($data);
$result = $upload _img->add (); if (! $result) {$this->error (' Upload failed!
