phpcms V9 实现调用上一篇和下一篇: 上一篇:{$previous_page[title]},下一篇:{$next_page[title]}...
方法一:
<div class="info">
    <span>上一篇:<a href="{$previous_page[url]}">{$previous_page[title]}</a></span>
    <span>下一篇:<a href="{$next_page[url]}">{$next_page[title]}</a></span>
</div>
方法二:下面的方法复杂了些,但该代码提供一种phpcms的调用数据的一种思路,大家可以参考,这也是phpcms区别与其他系统的优势
上一篇: 
{pc:get sql="SELECT * FROM v9_news WHERE id < $id ORDER BY id DESC" num="1" return="p"}
{loop $p $pv}  
{php $pid = "id = $pv[id]"}
{pc:content action="lists" catid="$catid" where="$pid" order="id DESC" num="1"} 
<ul> 
{loop $data $key $val}
<li> <a href="{$val['url']}">{$val['title']}</a></li> 
{/loop}  
</ul>  
{/pc}
{/loop}
{/pc}  
 
下一篇: 
{pc:get sql="SELECT * FROM v9_news WHERE id > $id ORDER BY id ASC" num="1" return="ne"}
{loop $ne $nev}  
{php $neid = "id = $nev[id]"} 
{pc:content action="lists" catid="$catid" where="$neid" order="id DESC" num="1"} 
<ul>  
{loop $data $key $val}
<li> <a href="{$val['url']}">{$val['title']}</a></li>  
{/loop}
</ul> 
{/pc} 
{/loop}
{/pc}
