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

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;
- }
- 图片列表
- <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>

- <div class="auth cl">
