phpcmsHow to retrieve the recently updated articles?

phpcms v9 calls the latest articles of the entire site (all contents have been updated recently)

The first step is to modify phpcms\modules\content\classes content_tag.class.php Add

public function newcontent($data){
$num = intval($data[&#39;limit&#39;]) ? intval($data[&#39;limit&#39;]) : &#39;20&#39;;
// 设置排序
switch($data[&#39;order&#39;]){
case &#39;1&#39;:
$order = &#39; `id` ASC &#39;;
break;
case &#39;2&#39;:
$order = &#39; `id` DESC &#39;;
break;
case &#39;3&#39;:
$order = &#39; `inputtime` ASC &#39;;
break;
case &#39;4&#39;:
$order = &#39; `inputtime` DESC &#39;;
break;
case &#39;5&#39;:
$order = &#39; `updatetime` ASC &#39;;
break;
case &#39;6&#39;:
$order = &#39; `updatetime` DESC &#39;;
break;
default:
$order = &#39; `id` DESC &#39;;
}
if($data[&#39;catid&#39;]){
$catids = explode(&#39;,&#39;, $data[&#39;catid&#39;]);
foreach($catids as $catid){
$catid = intval($catid);
if(empty($catid))continue;
$this->set_modelid($catid);
$where = $this->category[$catid][&#39;child&#39;] ? &#39; `catid` IN (&#39;.$this->category[$catid][&#39;arrchildid&#39;].&#39;)&#39; : " `catid` = $catid";
$datas = $this->db->select($where, &#39;*&#39;, $num, $order);
$data[$catid][&#39;data&#39;] = $datas;
// 记录本次的文章数
$data[&#39;num&#39;][] = count($datas);
$model_num++;
}
}else{
$models = getcache(&#39;model&#39;, &#39;commons&#39;);
foreach($models as $model){
$this->db->set_model($model[&#39;modelid&#39;]);
$datas = $this->db->select(&#39;&#39;, &#39;*&#39;, $num, $order);
$data[$model[&#39;modelid&#39;]][&#39;data&#39;] = $datas;
// 记录本次的文章数
$data[&#39;num&#39;][] = count($datas);
$model_num++;
}
}
if($data){
// 获取每个模型应该截取的条数
$num = ceil($num/$model_num);
// 循环条数记录用于找出条数不满足的数量然后进行平均
$w_num = $w_num_t = &#39;&#39;;
foreach($data[&#39;num&#39;] as $num_t){
if($num_t < $num){
$w_num += $num-$num_t;
$w_num_t++;
}
}
// 判断是否有不满足平均数的 如果有那么就增加平均值
if($w_num_t){
$num += ceil($w_num/($model_num-$w_num_t));
}
$datas = array();
foreach($data as $r){
$r_n = &#39;&#39;;
if(is_array($r[&#39;data&#39;]))
foreach($r[&#39;data&#39;] as $r_t){
$datas[] = $r_t;
if(++$r_n == $num)break;
}
}
return $datas;
}else{
return false;
}
