栏目调用详解

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;
}
}

 
第二步：模板调用  
 
其实就和默认的文章列表调用差不多
