Add an upload file to a database

            $id = $this->add(array('user_id'=>1,'upload_url'=>$info_v['upload'],'c_time'=>NOW_TIME,'size'=>$info_v['size'],'type'=>$type));        }        if($id){            return $id;        }else{            return '上传失败';        }    }}

Upload method

protected function upload(){

$files = $_files[' upload ');

    $upload = new \Think\Upload();// 实例化上传类    //C方法是用来读取配置信息    $upload->maxSize   =     C('maxSize') ;// 设置附件上传大小    $upload->exts      =     C('exts');// 设置附件上传类型    $upload->savePath  =     C('savePath'); // 设置附件上传目录    $upload->saveName  =     C('saveName'); //  设置上传文件的保存规则    $upload->rootPath  =     C('rootPath');    // 上传文件    $info   =   $upload->upload();    //         print_r($info);die;    $img_arr=array();    if(!$info) {        // 上传错误提示错误信息        return $upload->getError();    }else{        foreach ($info as $k=>$v){            //拼接文件存储路径            $img_url = C('img_path').$v['savepath'].$v['savename'];            $img_arr[$k]['upload']= $img_url;            $img_arr[$k]['size']= $v['size'];        }        return $img_arr;    }}
