织梦读取数据库几个用法
调取ID为16 标题长度为40 简介长度为50 降序desc（升序asc）的第一条（ 第2到5条为limit=’1,4’ ）
{dede:arclist typeid='16' titlelen='40' infolen='50' orderway='desc' limit='0,1' }
"[field:picname/]" width="158" height="119">
"[field:arcurl /]" title="[field:fulltitle /]" >[field:title /]
[field:description function="cn_substr(Html2text(@me),180)"/]...
{/dede:arclist}ID15 20条 简介50 标题10
{dede:arclist row="20" typeid="15" titlelen="10" infolen="50"}
"[field:typeurl/]" title="[field:fulltitle/]" >[[field:typename/]]"[field:arcurl /]">[field:title /]
{/dede:arclist}自动获取页面提交的时间
<input name="hzlytime" type="text" class="bor" />
<script language="javascript" type="text/javascript">
var c=new Date().toLocaleString();
document.write("");
script>列表ID等于1加特别css style=display:block
{dede:arclist row=6 typeid='20' titlelen='80' orderway='desc' addfields='sydt' channelid='1' }

{/dede:arclist}调取某条ID为156新闻的自定义字段
{dede:arclist typeid='49' idlist='156' addfields='trueprice,brand,yfty,yfwy,yftr,yfwe,yfts,yfws,yftss,yfwss,yftw,yfww,yftl,yfwl' channelid='6' }
[field:yfwy/]
{/dede:arclist}根据页面ID 显示不同的内容
<div {dede:field name='typeid' runphp='yes'} if(@me==24) @me='style=display:block'; else @me='style=display:none'; {/dede:field} >
typeid为24显示
div>
<div {dede:field name='typeid' runphp='yes'} if(@me==39) @me='style=display:block'; else @me='style=display:none'; {/dede:field} >
typeid为39显示
