phpcms V9调用全站最新文章的标签及修改使用方法

修改方法：

第一步、

修改 phpcms\modules\content\classes\content_tag.class.php 在最后面的 }上面添加

    public function newcontent($data){
    $num = intval($data['limit']) ? intval($data['limit']) : '20';
    // 设置排序
    switch($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;
    // 记录本次的文章数
    $data['num'][] = count($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;
    // 记录本次的文章数
    $data['num'][] = count($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 = $w_num_t = '';
    foreach($data['num'] 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){
    $r_n = '';
    if(is_array($r['data']))
    foreach($r['data'] as $r_t){
    $datas[] = $r_t;
    if(++$r_n == $num)break;
    }
    }
    return $datas;
    }else{
    return false;
    }
    }
