dedecms织梦模板中调用当前栏目文章数量

此方法适合dedecms5.6及5.7版本
修改织梦程序 include/common.func.php文件，在最后加以下代码：

//统计栏目文章数
function GetTotalArc($tid){
  global $dsql;
  $sql = GetSonIds($tid);
  $row = $dsql->GetOne("Select count(id) as dd From design_archives where typeid
in({$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
$sql = "SELECT id FROM `dede_arctype` WHERE id=’$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 = $dsql->GetOne("select count(*) as num from `design_archives` where typeid
in($ty)");
//echo $t_num[num];
if(is_array($t_num)){
  return " ".$t_num[num]." ";
}else{
  return "0" ;
}
}

织梦模板里的调用代码:

(该类拥有{dede:type}[field:id function="dynamic_num(@me)" /]{/dede:type}
个文档)

和
[field:ID runphp='yes'] @me = GetTotalArc(@me);[/field:ID]

例如模板里添加代码如下：
{dede:field name=’typename’/}</b>(该类拥有{dede:type}[field:id 
function="dynamic_num(@me)" /]{/dede:type}个文档)
{dede:channel type=’son’ }

<li><a href=’[field:typelink/]‘>[field:typename/]</a>(<span>[field:ID 
runphp='yes'] @me = GetTotalArc(@me);[/field:ID]</span>)</li>
{/dede:channel}
