(元素模板) / 2019-09-24 17:32

帝国cms根据Tags调用相关文章以下代码放到/e/class/userfun.php里!

<?php
function user_otherlink($limit=5){
        global $dbtbpre,$empire,$navinfor,$class_r;
    if($navinfor[infotags]){
            $classid=(int)$classid;
        $limit=(int)$limit;

        $num=ceil($limit/count($tagarr));
        foreach($tagarr as $k=>$v){
                        if(count($tagarr)==$k+1){
                                $num=$limit-count($arr);
                        }else{
                                if($i<$num){
                                        $num=ceil(($limit-count($arr))/count($tagarr));
                                }               
                        }
            $t=$empire->fetch1("select tagid,num from {$dbtbpre}enewstags where tagname='$v'");

                                while($s=$empire->fetch($sql)){

                                                $i++;
                                        }
                                        if($i==$num){
                                                break;
                                        }
                                        if(count($arr)==$limit){
                                                break 2;
                                        }
                                }
                                if($t[num]>$num){

                        }
        }
        if(count($arr)>0){
                        $inid=implode(",",$arr);

                                while($s=$empire->fetch($sql)){

                                                break;
                                        }
                                }
                        }
                        $inid=implode(",",$arr);
                        $str="";
                        $news=$empire->query("select id,title,titleurl,titlepic from
                       {$dbtbpre}ecms_{$tbname} where id in($inid)");
                        while($n=$empire->fetch($news)){
                                $str.='<li><a href="'.$n[titleurl].'">'.$n[title].'</a></li>';
                        }       
                }
        return $str;
           }
}
?>


内容页模板用以下代码调用:5为显示数量 自己改

<?=user_otherlink(5)?>
