比如招聘和求職，企業會員只出招聘，普通會員只出求職

<?php$modsql=$empire->query("select mid,qmname from {$dbtbpre}enewsmod where usemod=0 and showmod=0 and qenter<>'' order by myorder,mid");while($modr=$empire->fetch($modsql)){if(getcvar('mlgroupid')==個人會員組ID&&$modr[mid]==招聘系統模型ID){continue;}if(getcvar('mlgroupid')==企業會員組ID&&$modr[mid]==求職系統模型ID){continue;}?><li><img src="/skin/member/images/list.gif" /><a href="/e/DoInfo/ListInfo.php?mid=<?=$modr[mid]?>"><?=$modr[qmname]?></a><em><a href="/e/DoInfo/ChangeClass.php?mid=<?=$modr[mid]?>">發布</a></em></li><?}?>

可以同時能寫多個會員組id

if((getcvar('mlgroupid')==企業會員組ID||getcvar('mlgroupid')==會員組ID2)&&$modr[mid]==求職系統模型ID
