帝国cms 内容页根据关键词来调用相关内容，如果没有相关内容则随机获得文章代码：<?phpif ($navinfor['keyboard']){$c_key=explode(',',$navinfor['keyboard']);$count=count($c_key);for($i=0;$i<$count;$i++){if($i==0){$or='';}else{$or=' or ';}$repadd.=$or."keyboard like '%".$c_key[$i]."%'";}$r=$empire->fetch1("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$repadd." order by newstime desc limit 1");if($r[title]){$mesql=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$repadd." order by newstime desc limit 10");while($or=$empire->fetch($mesql)){$newstime=date('Y-m-d',$or[newstime]);?><li><a href="<?=$or[titleurl]?>"><?=$or[title]?></a><span><?=$newstime?></span></li><?}}else{$mesql2=$empire->query("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." order by rand() desc limit 10");while($r2=$empire->fetch($mesql2)){$newstime=date('Y-m-d',$o2[newstime]);?><li><a href="<?=$r2[titleurl]?>"><?=$r2[title]?></a><span><?=$newstime?></span></li><?}}}else{$mesql2=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news order by rand() desc limit 10");while($r2=$empire->fetch($mesql2)){$newstime=date('Y-m-d',$r2[newstime]);?><li><a href="<?=$r2[titleurl]?>"><?=$r2[title]?></a><span><?=$newstime?></span></li><?}}?>如修改文章条数的话，把limit后面的数字改一下就好了。
