如果需要实现该呈现方式,我们需要首先了解discuz封面图片存储原理:
discuz没有将主题列表封面路径存在数据表中,只是在pre_forum_thread表中存了一个cover标识。然后用getthreadcover 函数调取,diy调用的图片也会产生缩略图,可以设置缩略图的质量。
封面图片存储路径格式:data/attachment/forum/threadcover/43/ec/81.jpg
getthreadcover 函数:
    function getthreadcover($tid, $cover = 0, $getfilename = 0) {  
      global $_G;  
      if(emptyempty($tid)) {  
        return '';  
      }  
      $coverpath = '';  
      $covername = 'threadcover/'.substr(md5($tid), 0, 2).'/'.substr(md5($tid), 2, 2).'/'.$tid.'.jpg';  
      if($getfilename) {  
        return $covername;  
      }  
      if($cover) {  
        $coverpath = ($cover < 0 ? $_G['setting']['ftp']['attachurl'] : $_G['setting']['attachurl']).'forum/'.$covername;  
      }  
      return $coverpath;  
    }

处理封面图:
    
{eval   
      $covername = 'threadcover/'.substr(md5($thread[tid]), 0, 2).'/'.substr(md5($thread[tid]), 2, 2).'/'.$thread[tid].'.jpg';  
        
      $coverpath = ($cover < 0 ? $_G['setting']['ftp']['attachurl'] : $_G['setting']['attachurl']).'forum/'.$covername;  
    }  
    <li style="width: 227px;  left: 0px; top: 0px;float:left;">  
      <div class="c cl">  
      <a class="z" title="$thread[subject]" onclick="atarget(this)" href="forum.php?mod=viewthread&tid=$thread[tid]">  
      <img width="203" alt="$thread[subject]" src="{eval echo $coverpath;}">  
      </a>  
      </div>  
      <h3 class="xw0">  
      <a href="forum.php?mod=viewthread&tid=$thread[tid]" onclick="atarget(this)" target="_blank" {if $thread['displayorder'] == -1}class="recy"{/if}>$thread[subject]</a>  
      </h3>  
      <div class="auth cl">
