$upload=new \Think\Upload();//实例化上传类
$upload->maxSize = 3000000 ;// 设置附件上传大小 C('UPLOAD_SIZE');
$upload->rootPath = './Uploads/';
$upload->savePath = './Uploads/' . 'thumb/'; // 设置附件上传目录
$upload->exts = array('jpg', 'gif', 'png', 'jpeg'); // 设置附件上传类型
$upload->saveRule = 'time';
$upload->replace = true; //是否存在同名文件是否覆盖
$upload->thumb = true; //是否对上传文件进行缩略图处理
$upload->thumbMaxWidth = '100,150'; //缩略图处理宽度
$upload->thumbMaxHeight = '50,150'; //缩略图处理高度
$upload->thumbPrefix = 'm_,s_'; //生产2张缩略图
$upload->thumbPath = './Uploads/' . 'thumb/' . date('Ymd', time()) . '/'; //缩略图保存路径
$upload->thumbRemoveOrigin = false; //上传图片后删除原图片
$upload->autoSub = true; //是否使用子目录保存图片
$upload->subType = 'date'; //子目录保存规则
$upload->dateFormat = 'Ymd'; //子目录保存规则为date时时间格式
$info=$upload->upload(); 最佳答案
