phpcms V9 在首页显示或排除某些栏目的调用参数subcat(0,0,0,$siteid)使用说明

通过以下红色部分的栏目id来控制显示哪些栏目,id根据实际情况后台查询,subcat函数看最后附件解释,以下修改代码:

V9显示哪些栏目的方法

{loop subcat(6,0,0,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 infov}
              <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 infov}
                 <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}

phpcms V9排除某个栏目的方法

{loop subcat(6,0,0,siteid)r}
          {if $r['catid']==3 }<?php continue; ?>{/if} //排除某个栏目
          {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 infov}
              <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 infov}
                 <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}函数解释:

{loop subcat(0,0,0,siteid)r}{/loop}
/**
* 获取子栏目 
* @param parentid 父级id  
* @paramtype 栏目类型 1为单网页类型,0为栏目类型;(查看phpcms的mysql数据库可以看到)
* @param self 是否包含本身 0为不包含 
* @paramsiteid 站点id 
*/ 
function subcat(parentid = NULL,type = NULL,self = '0',siteid = '') { 
        if (empty(siteid))siteid = get_siteid(); 
        category = getcache('category_content_'.siteid,'commons'); 
        foreach(category asid=>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;        }        returnsubcat; 
}

表示在分类ID=50以内的栏目终止循环

{loop subcat(0,0,0,siteid)r}
{php num++}
{php if(
r['catid']==50)break;}
...
{/loop}

表示遇到栏目分类ID9、10、11、12、13、14时,跳出循环,也就是隐藏指定分类ID

{loop subcat(0,0,0,siteid)r}
{php num++}
{php if(
r['catid']==9 || r['catid']==10 ||r['catid']==11 || r['catid']==12 ||r['catid']==13 || $r['catid']==14)continue;}
...
{/loop}
