调取DedeCMS当前栏目文档数的方法

//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" ;
}
}
