根據欄目取商品：

/*取出指定欄目的商品

cat_id 對應的欄目下，可能沒有商品，

商品放在大欄目下的分類中

正確的做法是：找出cat_id的所有子孫欄目下的所有商品

*/

publicfunctioncatGoods($cat_id){

$category = new CatModel();

$cats = $category->select();//取出的欄目

$sons = $category->getCatTree($cats,$cat_id);//取出給定欄目的子孫欄目

$sub = array();

if(!empty($sons)){

foreach($sons as $v){

$sub[] = $v['cat_id'];

}

}

$in = implode(',',$sub);

$sql = 'select goods_id,goods_name,shop_price,market_price,thumb_img  from '.$this->table.' where cat_id in ( '.$in.') order by add_time limit  5';

return $this->db->getAll($sql);
