帝国cms相关链接无内容时调用当前栏目最热信息的方法

这篇文章主要为大家分享下帝国cms相关链接无内容时调用当前栏目最热信息的方法，需要的朋友可以参考下

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 $link_num");while($link_r=$empire->fetch($key_sql)){$text=RepOtherTemp($temp_r[1],$link_r,$tr);$text=str_replace('[!--no--]',$i,$text);$text=str_replace('[!--state--]',$link_r[state],$text);$text=str_replace('[!--lastvolume--]',$link_r[lastvolume],$text);$keyboardtext.=$text;//$keyboardtext.=RepOtherTemp($temp_r[1],$link_r,$tr);}$keyboardtext=$temp_r[0].$keyboardtext.$temp_r[2];}else{$keyid=GetKeyid($keyboard,$classid,0,$link_num);if($keyid){$fsql=$empire->query("update {$dbtbpre}ecms_".$class_r[$classid][tbname]."_data_1 set keyid='$keyid' where id='$id'");$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 $link_num");while($link_r=$empire->fetch($key_sql)){$text=RepOtherTemp($temp_r[1],$link_r,$tr);$text=str_replace('[!--no--]',$i,$text);$text=str_replace('[!--state--]',$link_r[state],$text);$text=str_replace('[!--lastvolume--]',$link_r[lastvolume],$text);$keyboardtext.=$text;//$keyboardtext.=RepOtherTemp($temp_r[1],$link_r,$tr);}$keyboardtext=$temp_r[0].$keyboardtext.$temp_r[2];}else{$add="";$tr=$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 order by onclick desc limit $link_num");while($link_r=$empire->fetch($key_sql)){$text=RepOtherTemp($temp_r[1],$link_r,$tr);$text=str_replace('[!--no--]',$i,$text);$text=str_replace('[!--state--]',$link_r[state],$text);$text=str_replace('[!--lastvolume--]',$link_r[lastvolume],$text);$keyboardtext.=$text;//$keyboardtext.=RepOtherTemp($temp_r[1],$link_r,$tr);}$keyboardtext=$temp_r[0].$keyboardtext.$temp_r[2];}//----------------------------------------------------------------------------------------------//$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");
