织梦dedecms如何调用当前栏目文章数

//统计栏目文章数
function GetTotalArc($tid){
global $dsql;
$sql = GetSonIds($tid);
$row = $dsql->GetOne("Select count(id) as dd From zmb_archives where typeid 
in({$sql})");
return $row['dd'];
}
//统计当前栏目信息数 
function dynamic_num($current_id){ 
global $dsql; 
//读取当前栏目的子ID 
$sql = "SELECT id FROM zmb_arctype WHERE id='$current_id' || 
topid='$current_id'"; 
$dsql->SetQuery($sql); 
$dsql->Execute(); 
while($row = $dsql->GetArray()){ 
$arr[]=$row[id]; 
} 
foreach($arr as $key=>$value){ 
$type .= $value . ','; 
} 
$ty= "".$type."0"; 
//echo $ty; 
$t_num = $dsql->GetOne("select count(*) as num from zmb_archives where typeid 
in($ty)"); 
//echo $t_num[num]; 
if(is_array($t_num)){ 
return " ".$t_num[num]." "; 
}else{ 
return "0" ; 
} 
}
