Answer 1

public function upload(){
    $upload_img=M('upload_img');//上传文件路径写入的表
    if(!empty($_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('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型
        $upload->rootPath  =      './upload/'; // 设置附件上传根目录
        $upload->savePath  =      date('Y-m-d'); // 设置附件上传（子）目录
        $upload->saveName=array('uniqid','');//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('date','Ymd');
        // 上传单个图片
        $info   =   $upload->uploadOne($_FILES['image']);
        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['savepath'].$info['savename'];
            $data['img_url']=$img_url;
            $data['img_name']=$info['savename'];
            $data['create_time']=time();
            $upload_img->create($data);
            $result=$upload_img->add();
            if(!$result){
                $this->error('上传失败！');
            }else{
                $this->success('上传成功');
            }
