discuz X3空间主题列表 图片展现模式,discuz实现个人空间主题列表调用图片模式,discuz home图片列表 

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 $_G;
  if(empty($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;
}
文件路径:/source/function/function_forum.php

实现方法:

修改:/source/language/home/lang_template.php

添加like 喜欢或查看

修改:/template/default/home/space_thread.htm

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;
}
