SUPESITE7.5文章内容页的上一篇下一篇标题显示调用方法

刚在网上搜索几篇文章发现都 不能用，发现sql语句有错，然后我就修改去掉了folder=1的条件
1：修改处理程序viewnews.php
找到：

1	include template($tplname);

在其前面加入

1 2 3 4 5

$title_a = $_SGLOBAL['db']->result($_SGLOBAL['db']->query('SELECT subject FROM '.tname('spaceitems').' WHERE itemid < \''.$itemid.'\' AND catid = \''.$thecat['catid'].'\' AND type=\'news\' ORDER BY itemid DESC LIMIT 0,1'), 0); if(!$title_a) $title_a = '';   $title_b = $_SGLOBAL['db']->result($_SGLOBAL['db']->query('SELECT subject FROM '.tname('spaceitems').' WHERE itemid > \''.$itemid.'\' AND catid = \''.$thecat['catid'].'\' AND type=\'news\' ORDER BY itemid LIMIT 0,1'), 0); if(!$title_b) $title_b = '';

2：修改模版文件news_view.html.php
找到上一遍及下一遍处

1 2 3

<div id="article_pn"> <a class="box_l" href="{S_URL}/batch.common.php?ction=viewnews&amp;op=up&amp;itemid=$news[itemid]&amp;catid=$news[catid]">上一篇</a> <a class="box_r" href="{S_URL}/batch.common.php?action=viewnews&amp;op=down&amp;itemid=$news[itemid]&amp;catid=$news[catid]">下一篇</a> </div>

将其替换为

1 2 3 4

<div id="article_pn"> <span class="box_l">上一篇：<a href="{S_URL}/batch.common.php?action=viewnews&op=up&itemid=$news[itemid]&catid=$news[catid]" class="viewnewsup">$title_a</a></span> <span class="box_r">下一篇：<a href="{S_URL}/batch.common.php?action=viewnews&op=down&itemid=$news[itemid]&catid=$news[catid]">$title_b</a></span> </div>
