1.显示指定catid的栏目名称和链接 {$CATEGORYS[25]['catname']} {$CATEGORYS[25]['url']}
获取父栏目id/获取父栏目名称
$CATEGORY[$catid][parentid]}
父栏目名称：{$CATEGORYS[$CAT[parentid]][catname]}
去掉标题限制后出现的省略号
{str_cut($r[title],36,'')}
格式化时间 2011-05-06 11:22:33
{date('Y-m-d H:i:s',$r[inputtime])}
{date('Y年m月d日',$r[inputtime])}
------------------------------------------------------------------------------------------------------
2.调用子栏目（在栏目首页模板需要用到,列表页也可以用到）
{pc:content action="category" catid="$catid" num="25"
siteid="$siteid" order="listorder ASC"}
{loop $data
$r}
<a
href="{$r[url]}">{$r[catname]}</a>
|
{/loop}{/pc}
------------------------------------------------------------------------------------------------------
3.得到指定栏目下的新闻
（1)这里moreinfo="1"表示主副表关联起来 可以直接使用
{pc:content action="lists" catid="$catid" num="25" order="id DESC"
return="info" moreinfo="1"}
{loop $info $r}
更新日期:{date('Y年m月d日',$r[updatetime])}
作者：{$r[username]}
来源：{$r[copyfrom]}
点击率{$r[readpoint]}
网址{$r[url]}
文章标题 {$r['title']}
标题样式{title_style($v[style])}
{/loop}
{/pc}
<p>=====================</p
（2）sql万能语句可以调用指定内容 更方便
{pc:get sql="select * from v9_news as a,v9_news_data as b where
a.id=b.id and catid=34 and status=99 order by a.id desc"}
{loop $data $v}
<li><a
href="{$v['url']}"
target="_blank"><img
src="{$v[thumb]}" width="146" height="117"
/></a></li>
{/loop}
{/pc}
{pc:get sql="select * from
v9_news where catid=10 and status=99 order by updatetime desc"
num="5" start="23"}
{loop $data $rs}
<a href="{$rs['url']}" title="{$rs['title']}"
target="_blank">{$rs['title']}</a>
{/loop}
{/pc}
<p>=====================</p
（3）文章从指定位置开始调用
（position推荐位使用）
起始位置为5，调用3条。相当于limit功能。
{pc:content action="position" posid="27"
order="listorder DESC" num="3" start="5"}
{loop $info $r}
<a
href='{$r[url]}'>{str_cut($r[description],115)}...
</a>
{/loop}
{/pc}
或{pc:content
action="lists" catid="54"
thumb="" order="listorder DESC"
start="3" num="5"} thumb="" 不分类
<p>=====================</p>循环列表新闻
<div
class="content">
{pc:content action="position"
posid="9" order="listorder DESC" num="4"}
{loop $data $r}
<a href="{$r[url]}"
title="{$r[title]}">{str_cut($r[title],36,'')}</a>{date('Y-m-d
H:i:s',$r[inputtime])}
<p>{if $n==1}<img
src="{thumb($r[thumb],90,60)}" width="90"
height="60"/>{/if}{str_cut($r[description],112,'')}<a
href="{$r[url]}">[reading
more]</a></p>
{/loop}
{/pc}
</div>
<p>=====================</p>
（4）.有分页效果
{pc:get
sql="select * from wecheweyounews where hour=$hour order by id
desc" return="data" num="50" page="$page"}
<ul >
{loop $data $r}
<li><span
class="left">·<a
href="{$r['url']}"
target="_blank">{str_cut($r['title'],60)}</a>(编辑：{$r[username]})</span><span
class="right">{date("Y-m-d",$r['inputtime'])}</span></li></li>
<?php
if($n%5==0 and $n<50) echo
"</ul><ul>";
?>
{/loop}
</ul>
</div>
<div id="pages"
class="text-c">{$pages}</div>
{/pc}
------------------------------------------------------------------------------------------------------
4. <!--首页焦点图推荐 就图片切换那个东西-->
{pc:content action="position"
posid="1" order="listorder DESC" thumb="1"
num="5"}
{loop $data $r}
<a href="{$r['url']}"
title="{str_cut($r['title'],30)}"><img
src="{thumb($r['thumb'],300,200)}" alt="{$r['title']}" width="310"
height="260"
/></a>
{/loop}
{/pc}
5分页
前台调用num="50"指每页50条记录
{pc:get
sql="select * from wecheweyounews where hour=$hour order by id
desc" return="data" num="50" page="$page"}
<ul >
{loop $data $r}
<li><span
class="left">·<a
href="{$r['url']}"
target="_blank">{str_cut($r['title'],60)}</a>(编辑：{$r[username]})</span><span
class="right">{date("Y-m-d",$r['inputtime'])}</span></li></li>
<?php
if($n%5==0 and $n<50) echo
"</ul><ul>";
?>
{/loop}
</ul>
</div>
<div id="pages"
class="text-c">{$pages}</div>
{/pc}
