discuz个人空间主题列表 图片模式实现方法

佚名 discuz教程
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
复制代码
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;}
