帝国cms 高效率随机调用tag的PHP代码

高效率随机调用：

<?php
$num=$empire->num("select tagid from {$dbtbpre}enewstags");
$randnum=100; 
$randids=''; 
$randdh=''; 
for($i=1;$i<=$randnum;$i++) 
{ 
$randids.=$randdh.rand(1,$num); 
$randdh=',';
} 
?>
[e:loop={"select tagname,tagid from phome_enewstags where tagid in ($randids)  limit $randnum",32,24,0}]
<a target="_blank" href="/tag/<?=$bqr['tagid']?>/" title="<?=$bqr['tagname']?>"><?=$bqr['tagname']?></a> | 
[/e:loop]

代码这里，修改url以及样式即可使用，随机高效率代码

正常调用：

[e:loop={"select tagname,tagid from phome_enewstags  limit 12 ",32,24,0}]
<a target="_blank" href="/e/tags/?tagname=<?=$bqr['tagname']?>" title="<?=$bqr['tagname']?>"><?=$bqr['tagname']?></a> | 
[/e:loop]

随机调用：

[e:loop={"select tagname,tagid from phome_enewstags  order by rand() limit 12 ",32,24,0}]
<a target="_blank" href="/e/tags/?tagname=<?=$bqr['tagname']?>" title="<?=$bqr['tagname']?>"><?=$bqr['tagname']?></a> | 
[/e:loop]

内容页调用：

[e:loop={"select a.*,b.* from [!db.pre!]enewstags a LEFT JOIN [!db.pre!]enewstagsdata b ON a.tagid=b.tagid where b.classid='$navinfor[classid]' and b.id='$navinfor[id]' group by b.tagid order by a.num desc limit 10",0,24,0}]
<a href='<?=$public_r['newsurl']?>e/tags/?tagname=<?=$bqr['tagname']?>' title='<?=$bqr['num']?>个'><?=$bqr['tagname']?>(<?=$bqr['num']?>)</a>
[/e:loop]
