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}

       <ahref="http://www.mamicode.com/{$r[url]}">{$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 wherea.id=b.id and catid=34 and status=99 order by a.id desc"}
    {loop $data $v} 
 <li><ahref="http://www.mamicode.com/{$v[‘url‘]}"target="_blank"><imgsrc="http://www.mamicode.com/{$v[thumb]}" width="146" height="117"/></a></li>            
   {/loop}
    {/pc}

   {pc:get sql="select * fromv9_news where catid=10 and status=99 order by updatetime desc"num="5" start="23"}
  {loop $data $rs}
     <a href="http://www.mamicode.com/{$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 $r}
               <a href=http://www.mamicode.com/‘{$r[url]}‘>{str_cut($r[description],115)}...>      {/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
 
  <divclass="content">
        {pc:content  action="position"posid="9" order="listorder DESC" num="4"}
         {loop $data $r}
             <a href="http://www.mamicode.com/{$r[url]}"title="{$r[title]}">{str_cut($r[title],36,‘‘)}</a>{date(‘Y-m-dH:i:s‘,$r[inputtime])}
               <p>{if $n==1}<imgsrc="http://www.mamicode.com/{thumb($r[thumb],90,60)}" width="90"height="60"/>{/if}{str_cut($r[description],112,‘‘)}<ahref="http://www.mamicode.com/{$r[url]}">[readingmore]</a></p>
               
              {/loop} 
            {/pc}  
           </div>
<p>=====================</p>
（4）.有分页效果
    {pc:getsql="select * from wecheweyounews where hour=$hour order by iddesc" return="data" num="50" page="$page"}
               <ul >
       {loop $data $r}
                   <li><spanclass="left">&middot;<ahref="http://www.mamicode.com/{$r[‘url‘]}"target="_blank">{str_cut($r[‘title‘],60)}</a>(编辑：{$r[username]})</span><spanclass="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 $r}
  <a href="http://www.mamicode.com/{$r[‘url‘]}"title="{str_cut($r[‘title‘],30)}"><imgsrc="http://www.mamicode.com/{thumb($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:getsql="select * from wecheweyounews where hour=$hour order by iddesc" return="data" num="50" page="$page"}
               <ul >
       {loop $data $r}
                   <li><spanclass="left">&middot;<ahref="http://www.mamicode.com/{$r[‘url‘]}"target="_blank">{str_cut($r[‘title‘],60)}</a>(编辑：{$r[username]})</span><spanclass="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}
