第一步 修改 phpcms\modules\content\classes  content_tag.class.php  在最後面的 } 上面新增
public function newcontent($data){
$num = intval($data['limit']) ? intval($data['limit']) : '20';
// 設定排序
switch($data['order']){
case '1':
$order = ' `id` ASC ';
break;
case '2':
$order = ' `id` DESC ';
break;
case '3':
$order = ' `inputtime` ASC ';
break;
case '4':
$order = ' `inputtime` DESC ';
break;
case '5':
$order = ' `updatetime` ASC ';
break;
case '6':
$order = ' `updatetime` DESC ';
break;
default:
$order = ' `id` DESC ';
}
if($data['catid']){
$catids = explode(',', $data['catid']);
foreach($catids as $catid){
$catid = intval($catid);
if(empty($catid))continue;
$this->set_modelid($catid);
$where = $this->category[$catid]['child'] ? ' `catid` IN ('.$this->category[$catid]['arrchildid'].')' : " `catid` = $catid";
$datas = $this->db->select($where, '*', $num, $order);
$data[$catid]['data'] = $datas;
// 記錄本次的文章數
$data['num'][] = count($datas);
$model_num++;
}
}else{
$models = getcache('model', 'commons');
foreach($models as $model){
$this->db->set_model($model['modelid']);
$datas = $this->db->select('', '*', $num, $order);
$data[$model['modelid']]['data'] = $datas;
// 記錄本次的文章數
$data['num'][] = count($datas);
$model_num++;
}
}
if($data){
// 獲取每個模型應該擷取的條數
$num = ceil($num/$model_num);
// 迴圈條數記錄用於找出條數不滿足的數量然後進行平均
$w_num = $w_num_t = '';
foreach($data['num'] as $num_t){
if($num_t < $num){
$w_num += $num-$num_t;
$w_num_t++;
}
}
// 判斷是否有不滿足平均數的 如果有那麼就增加平均值
if($w_num_t){
$num += ceil($w_num/($model_num-$w_num_t));
}
$datas = array();
foreach($data as $r){
$r_n = '';
if(is_array($r['data']))
foreach($r['data'] as $r_t){
$datas[] = $r_t;
if(++$r_n == $num)break;
}
}
return $datas;
}else{
return false;
}
}

第二步：模板呼叫 

其實就和預設的文章列表呼叫差不多

{pc:content action="newcontent" }

引數說明：

catid: 可有可無  加了就只調用指定欄目的資訊  多個欄目請使用英文半形的 ,間隔

order:排序 引數值：1-7  具體的含義在程式碼裡面很容易看明白 不祥述

num:呼叫數量  不指定預設呼叫20條
