1.在IndexController.class.php里面写2个方法，shangchuan用来显示页面，upload是上传文件的方法。
<?php
namespace Home\Controller;
use Think\Controller; class IndexController extends Controller { public function shangchuan() { $this->display(); } public function upload() { $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 31457280 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->autoSub = true; $upload->subName = array('date','Ymd'); $upload->rootPath = "./Public/";//文件上传保存的根路径，下面的Upload文件夹放在这里面，./Public/Upload $upload->savePath = './Uploads/'; // 设置附件上传目录，文件上传上来以后放在了这个文件件里面。 $info = $upload->upload(); if(!$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 { foreach($info as $file){ echo $file['savepath'].$file['savename']; } } } }
2.显示页面
