帝国cms相关文章根据当前内容关键词调用

本文对内容页的相关内容调用提供详细代码示范实际使用中测试可用。
帝国cms当前内容页根据文章关键词调用相关内容,有关键词的情况下相关程度高，而没有填关键词的时候显示随机内容不会出现空白现象。
代码如下：
<?php
if ($navinfor['keyboard'])
{
$key=explode(',',$navinfor['keyboard']);
$count=count($key);
for($i=0;$i<$count;$i++)
{
if($i==0)
{
$or='';
}
else
{
$or=' or ';
}
$tjadd.=$or."keyboard like '%".$key[$i]."%'";
}
$r=$empire->fetch1("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$tjadd." order by newstime desc limit 1");
if($r[title])
{
$tjsql=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$tjadd." order by newstime desc limit 10");
while($rr=$empire->fetch($tjsql))
{
$newstime=date('Y-m-d',$rr[newstime]);
?>
<li><a href="<?=$rr[titleurl]?>"><?=$rr[title]?></a><span><?=$newstime?></span></li>
<?
}
}
else
{
 
$tjsql2=$empire->query("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." order by rand() desc limit 10");
while($r2=$empire->fetch($tjsql2))
{
$newstime=date('Y-m-d',$r2[newstime]);
?>
<li><a href="<?=$r2[titleurl]?>"><?=$r2[title]?></a><span><?=$newstime?></span></li>
<?
}
}
}
else
{
$tjsql2=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news   order by rand()  desc limit 10");
while($rd=$empire->fetch($tjsql2))
{
$newstime=date('Y-m-d',$rd[newstime]);
?>
<li><a href="<?=$rd[titleurl]?>"><?=$rd[title]?></a><span><?=$newstime?></span></li>
<?
}
}
