discuz的image类使用

<input type="attach" name="file">//文件域的名字
//处理方法
//新图
if(!empty($_FILES['attach']['tmp_name']) && is_uploaded_file($_FILES['attach']['tmp_name'])){
$query = DB::query("select filename,filepath from pre_home_hall_pic where picid =$picid ");
while ($value = DB::fetch($query)) {
$oldfilepath=$value['filepath'];
$filename =$value['filename'];
}
$file_info = pathinfo($_FILES['attach']['name']);
$ext = $file_info['extension'];// 取扩展名
$filepath = dirname($oldfilepath).'/'.date('His').strtolower(random(16)).'.'.$ext;//随机重命名
$uploadpath = 'data/attachment/hall/'.$filepath;
if(!is_dir('data/attachment/hall/'.$oldfilepath)){
unlink('data/attachment/hall/'.$oldfilepath);
unlink('data/attachment/hall/'.$oldfilepath.'');
}
$res = move_uploaded_file($_FILES['attach']['tmp_name'], $uploadpath);
if($res){
require_once libfile('class/image');
$image = new image();
$result = $image->Thumb($uploadpath, '', 140, 140, 1);
}
$data['filename'] = $_FILES['attach']['name'];
$data['filepath'] = $filepath;
}
DB::update('home_hall_pic', $data, $wherearr);
