Discuz手机版套用PC端相关帖子模板，如何实现帖子封面调用，叠加CSS实现效果如下：
调用方法如下：
1、进入Discuz程序目录source\module\forum，打开forum_viewthread.php文件
搜索$post[‘relateitem’]
修改为如下代码，新增相关帖子img地址。
- if($post[‘tags’]) {
- $post[‘relateitem’] = getrelateitem($post[‘tags’], $post[‘tid’], $_G[‘setting’][‘relatenum’], $_G[‘setting’][‘relatetime’]);
- foreach($post[‘relateitem’] as $k=>$img)
- {
- $threada= C::t(‘forum_attachment’)->fetch_all_by_id(‘tid’, $img[‘tid’], ‘aid’);
- $threadaid = reset($threada);
- $threadpic = C::t(‘forum_attachment_n’)->fetch_by_aid_uid($threadaid[‘tableid’], $threadaid[‘aid’], $thread[‘authorid’]);
- $thread[‘pic’] = $threadpic[‘attachment’];
- $post[‘relateitem’][$k][‘img’] = ‘/uploads/2024/’.$thread[‘pic’];
- }
- }

2、在需要调用帖子封面的位置，通过$var[img]进行调用。
- <!–相关推荐–>
- <div class=”r_list”>
- <h3 class=”r_list_title” style=”height: 30px;line-height: 30px;”>相关推荐</h3>
- <ul>
- <!–{loop $post[‘relateitem’] $var}–>
- <li><div class=”topic_img” style=”width: 100px;height: 70px;float: left;”><a href=”thread-$var[tid]-1-1.html” target=”_self”><img src=”<font color=”#ff0000″><b>$var[img]</b></font>” alt=”$var[subject]” width=”100px” height=”70px” /></a></div>
- <a href=”thread-$var[tid]-1-1.html” title=”$var[subject]” target=”_self”>$var[subject]</a></li>
- <!–{/loop}–>
- </ul>
- </div>
- <!—->
