帝国CMS实现无限级栏目调用的方法

1、打开 e/class/userfun.php 文件，添加如下函数代码

function dp_classmenu($bclassid,$i=0,$m=0){

global $empire,$dbtbpre,$public_r;

$bclassid=(int)$bclassid;

$i=(int)$i;

if(!$i){$i=1;}

$d=$i;

if($d>2){$d=2;}

$st='';

if($d>1&&$m==1){

$st=' start';

}

$returnstr='';

$i+=1;

$m=0;

$sql=$empire->query("select classid,classname,bclassid,islast,classpath from {$dbtbpre}enewsclass where bclassid='$bclassid' and wburl='' order by myorder,classid");

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

$returnstr.='

';

$classurl=$public_r['newsurl'].$r['classpath'].'/';

$m+=1;

if($r['islast']){

$qstr='&C';

$lian='';

$hstr='';

}else{

$qstr='&D';

$lian='class="lian"';

$hstr='-';

}

$returnstr.=$qstr.''.$exp.$r['classname'].''.$hstr;

if(empty($r['islast']))

{

$moreclassstr=dp_classmenu($r['classid'],$i,$m);

$returnstr.='';

}

$returnstr.="

";

}

return $returnstr;

}
