这个插件呢，是仿贴吧的，在帖子列表显示缩略图，是我很喜欢的一种风格，适用于x3.0，但是为了客户端，我只能用x2.5版本，这个插件在x2.5不工作，无法生成缩略图我就是想改一改代码，让其在x2.5环境下工作，自用，不商用。
在x3.0下，是能生成一个存放缩略图的文件夹，里面存放有缩略图。但是在2.5下，没有发现这个文件夹，所以感觉在build这一步出了问题。
下面贴出thumbbuilder.class.php这个文件的代码，请高手分析一下，为什么没有在data/attachment/下生成tiebalist这个文件夹。
basedir=!$_g['setting']['attachdir'] ? (discuz_root.'data/attachment/'):$_g['setting']['attachdir']; $this->baseurl=!$_g['setting']['attachurl'] ? ('data/attachment/'):$_g['setting']['attachurl']; } private function getcoverpath($tid){ return 'tiebalist/'.substr(md5($tid), 0, 2).'/'.substr(md5($tid), 2, 2).'/'; } public function getthreadcovers($tid,$aids){ $coverpath=$this->getcoverpath($tid); $fullpath=$this->basedir.$coverpath; $fullurl=$this->baseurl.$coverpath; $images=array(); foreach($aids as $aid){ if (file_exists($fullpath.$aid.'.jpg')) $images[]=array('aid'=>$aid,'thumbfile'=>$fullurl.$aid.'.jpg'); } return $images; } public function createthreadcovers($tid,$images,$force=0){ $path=$this->basedir.$this->getcoverpath($tid); dmkdir($path); global $_g; $setting=&$_g['cache']['plugin']['chs_tiebalist']; $thumbheight=$setting['thumbheight']?$setting['thumbheight']:80; $thumbmaxwidth=$setting['thumbmaxwidth']?$setting['thumbmaxwidth']:300; foreach($images as $aid=>$image){ $target=$path.$aid.'.jpg'; if (file_exists($target)&&(!$force)) continue; try { $thumb = phpthumbfactory::create($image,array('resizeup'=>true)); $dimensions=$thumb->getcurrentdimensions(); $newwidth=$thumbheight*$dimensions['width']/$dimensions['height']; if ($newwidth>$thumbmaxwidth) { $thumb->adaptiveresize($thumbmaxwidth,$thumbheight); }else { $thumb->resize(0,$thumbheight);//封面不限定宽度 } $thumb->save($target); }catch(exception $oex){//捕获生成缩略图可能抛出的异常，防止中断 writelog('tiebalistlog',$oex->getmessage()); continue; } } if ($force) { $thumbfiles=$this->getfiles($path,'jpg'); $aids=array_keys($images); foreach($thumbfiles as $filename){ $aid=intval(substr($filename,0,strpos($filename,'.'))); if (!in_array($aid,$aids)) unlink($path.$filename); } } } private function getfiles($dir,$mask=''){ $filearray=array(); if (false != ($handle = opendir ($dir))) { while (false!==($file=readdir($handle))){ if ($file == '.' || $file == '..') continue; if (empty($mask)) $filearray[]=$file; else if (substr(strrchr($file, '.'), 1)==$mask) $filearray[]=$file; } } return $filearray; }}?>
回复讨论(解决方案) buildthumb.inc.php内的内容，好像也有用处呢

这个你找原插件作者去瞅瞅吧！
