dedecms织梦dede:arclist按照自定义字段的条件调用相关文章，这对于想要在首页调用某个自定义字段的文章的同学来讲，非常不错  
打开 /include/taglib/arclist.lib.php 找到  
//关键字条件 在它的上面加入  
//自定义字段关键字条件 

if($ctag->GetAtt('addk')!='') {  
$addkeywords = explode(',' , trim($ctag->GetAtt('addk')));  
$addf = $ctag->GetAtt('addf') ? $ctag->GetAtt('addf') : "body";  
$filtersql = '';  
$n = 1;  
foreach($addkeywords as $k)   
{    
if(trim($k)=='') continue;    
else $k = addslashes($k);   
$filtersql .= ($filtersql=='' ? " find_in_set('$k', addf.$addf) " : " OR find_in_set('$k', addf.$addf) ");  
$n++;   
}  
 

$orwheres[] = $filtersql; } 

模板调用标签写法  

{dede:arclist typeid='1' row='10' channelid='1' addfields='jiage,dengji,shangdao,canyin' addk='奢华6星' addf='dengji'} <li>  
 
<a href="[field:arcurl/]">  
 
<img src="[field:litpic/]" width="143" border="0" height="106">  
 
<span class="title">[field:title/]</span><br/>  
 
<small>岛屿等级：[field:dengji/]</small>  
 
</a> </li> {/dede:arclist} 

channelid='1' //你的模型id号  
addfields='jiage,dengji,shangdao,canyin' //你的自定义字段  
addk='奢华6星' //要调用的自定义字段值  
addf='dengji' //要调用的自定义字段
