指定关键词调用
数据库查询方法，
select * from [!db.pre!]ecms_news where classid <434 and title like '%球阀%' order by id desc

[e:loop={15,8,0,0,"字段名 like '%淡季%'",''}]
比如调用标题带有淡季这个单词的文章
[e:loop={'news',10,18,0,"title like '%淡季%'",''}]
如果是自定也列表的话，调用关键词，用这个方法，
或者用下面的方法获取，现获取关键词，在调用，classid >434 and是要显示的id

<?php
       $pageid=str_replace("list","",$classid);
       $cr2=$empire->fetch1("select pagekeywords from phome_enewsuserlist where listid= '".$GLOBALS[navclassid]." limit 1'");
       $dcm=$cr2['pagekeywords'];
       $ecms_bq_sql=sys_ReturnEcmsLoopBq("select * from phome_ecms_news where classid >434 and title like '%".$dcm."%' order by newstime limit 10",14,24,0);
    while($bqr=$empire->fetch($ecms_bq_sql))
    {
?>
<div class="proclass_nav"><a href="<?=$bqr['titleurl']?>" title="<?=$bqr['title']?>"><?=$bqr['title']?></a></div>

<?php
    }
    
?>
