帝国cms相关链接无内容时调用当前栏目最热信息

帝国cms相关链接，这里以帝国cms 7.0为例

具体代码 在/e/class/functions.php

$keyboardtext='<?=GetKeyboard($ecms_gr[keyboard],$ecms_gr[keyid],$ecms_gr[classid],$ecms_gr[id],$class_r[$ecms_gr[classid]][link_num])?>';

可以看到相关链接的信息是通过GetKeyboard得到，找到 GetKeyboard修改一下就可以了，也是在/e/class/functions.php

//取得相关链接
function GetKeyboard($keyboard,$keyid,$classid,$id,$link_num){
    global $empire,$public_r,$class_r,$fun_r,$dbtbpre;
    if($keyid&&$link_num)
    {
        $add="id in (".$keyid.")";
        $tr=$empire->fetch1("select otherlinktemp,otherlinktempsub,otherlinktempdate from ".GetTemptb("enewspubtemp")." limit 1");//取得相关链接模板
        $temp_r=explode("[!--empirenews.listtemp--]",$tr[otherlinktemp]);
        $key_sql=$empire->query("select id,newstime,title,isurl,titleurl,classid,titlepic,lastvolume from {$dbtbpre}ecms_".$class_r[$classid][tbname]." where ".$add." order by newstime desc limit $link_num");

        //$keyboardtext=$fun_r['NotLinkNews'];
    }
    return $keyboardtext;
}

原来的官方代码

在没有关键字的时候直接就给出

$keyboardtext=$fun_r['NotLinkNews'];

这显示无相关信息

我做了一个无keyid的时候再去获取一次keyid，

$keyid=GetKeyid($keyboard,$classid,0,$link_num);

确实没有关键字的时候读取人气最高的几条信息

$key_sql=$empire->query("select id,newstime,title,isurl,titleurl,classid,titlepic,lastvolume from {$dbtbpre}ecms_".$class_r[$classid][tbname]." where  order by onclick desc limit $link_num");
