dede根据关键字调用相关文章实现如下：

{dede:field name=’ID’ runphp=’yes’}
$tempid=@me;
@me=”";
{/dede:field}
{dede:field name=’keywords’ runphp=’yes’}
@me=”%”.str_replace(” “,”%”,@me).”%”;

if(!isset($dsql) || !is_object($dsql)){
    $dsql = new DedeSql(false);
}
$dsql->SetQuery(“Select arcf.title,arcf.url from `dede_full_search` arcf left join `dede_arctype` tp on arcf.typeid=tp.ID where arcf.arcrank > -1 And arcf.keywords like ‘”.@me.”‘ and aid<>”.$tempid.” order by arcf.aid desc limit 0,20″);
$dsql->Execute();
@me=”";
while($row = $dsql->GetArray())
{
    @me.=”<li><a href=’”.$row['url'].”‘ target=’_blank’>”.$row['title'].”</a></li>”;
}
{/dede:field}
适用于：只有一个关键字的文档．
