织梦dedecms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)</b>
{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}
