phpcms首页若何只显示指定栏目

上面的代码经过栏目id来管制显示哪些栏目，id依据实际状况后盾查问，subcat函数看最初附件诠释，如下修正代码：

{loop subcat(0,0,0,$siteid) $r}
  {if $r['catid']==1||$r['catid']==2 } //显示哪些栏目
        {php $num++}
        <div class="box cat-area" {if $num%2!=0}style=" margin-right:10px"{/if}>
          <h5 class="title-1">{$r}<a href="{$r}" class="more">更多>></a></h5>
             <div class="content">
             {pc:content  action="lists" catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
             {loop $info $v}
              <p>
               <img src="{thumb($v,90,0)}" width="90" height="60"/>
                    <strong><a   target="_blank" title="{$v['title']}"{title_style($v)}>{str_cut($v['title'],28)}</a></strong><br />{str_cut($v['description'],100)}
                </p>
              {/loop}
              {/pc}               
                <div class="bk15 hr"></div>
                {pc:content action="lists" catid="$r" num="5" order="id DESC" return="info"}
                <ul class="list lh24 f14">
                {loop $info $v}
                 <li>·<a href="{$v['url']}" target="_blank" title="{$v['title']}"{title_style($v)}>{str_cut($v['title'],40)}</a></li>
                {/loop}
                </ul>
                {/pc}
            </div>
        </div>
        {if $num%2==0}<div class="bk10"></div>{/if}
  {/if}
  {/loop}

除了了指定特定的栏目，咱们也能够应用扫除的形式，显示特定的栏目

V9扫除某个栏目的办法

{loop subcat(0,0,0,$siteid) $r}
          {if $r['catid']==3 }<?php continue; ?>{/if} //扫除某个栏目
          {php $num++}
        <div class="box cat-area" {if $num%2!=0}style=" margin-right:10px"{/if}>
          <h5 class="title-1">{$r}<a href="{$r}" class="more">更多>></a></h5>
             <div class="content">
             {pc:content  action="lists" catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
             {loop $info $v}
              <p>
               <img src="{thumb($v,90,0)}" width="90" height="60"/>
                    <strong><a   target="_blank" title="{$v['title']}"{title_style($v)}>{str_cut($v['title'],28)}</a></strong><br />{str_cut($v['description'],100)}
                </p>
              {/loop}
              {/pc}               
                <div class="bk15 hr"></div>
                {pc:content action="lists" catid="$r" num="5" order="id DESC" return="info"}
                <ul class="list lh24 f14">
                {loop $info $v}
                 <li>·<a href="{$v['url']}" target="_blank" title="{$v['title']}"{title_style($v)}>{str_cut($v['title'],40)}</a></li>
                {/loop}
                </ul>
                {/pc}
            </div>
        </div>
        {if $num%2==0}<div class="bk10"></div>{/if}
  {/loop}

{loop subcat(0,0,0,$siteid) $r}{/loop}函数诠释：

/**
* 猎取子栏目 
* @param $parentid 父级id  
* @param $type 栏目类型 1为单网页类型，0为栏目类型；（查看phpcms的mysql数据库能够看到）
* @param $self 能否蕴含自身 0为没有蕴含 
* @param $siteid 站点id 
*/ 
function subcat($parentid = NULL, $type = NULL,$self = '0', $siteid = '') { 
        if (empty($siteid)) $siteid = get_siteid(); 
        $category = getcache('category_content_'.$siteid,'co妹妹ons'); 
        foreach($category as $id=>$cat) { 
                if($cat['siteid'] == $siteid && ($parentid === NULL || $cat['parentid'] == $parentid) && ($type === NULL || $cat['type'] == $type)) $subcat[$id] = $cat; 
                if($self == 1 && $cat['catid'] == $parentid && !$cat['child'])  $subcat[$id] = $cat; 
        } 
        return $subcat; 
}
