phpcms首頁如何只顯示指定欄位
下面的程式碼透過欄位id來控制顯示哪些欄目,id根據實際情況後台查詢,subcat函數看最後附件解釋,以下修改程式碼:
{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 $num%2==0}<div class="bk10"></div>{/if} {/if} {/loop}
除了指定特定的欄目,我們也可以使用排除的方式,顯示特定的欄位
##V9排除某個欄目的方法
{loop subcat(0,0,0,$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 $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}函數解釋:#
/** * 获取子栏目 * @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数据库可以看到) * @param $self 是否包含本身 0为不包含 * @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,'commons'); 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; }PHP中文網,大量的免費
