Ecshop修改后台的大分类商品数量

Ecshop修改后台的大分类商品数量

 


修改后效果：

 


 

 

解决方法：

1.修改ecshop/includes/lib_common.php文件代码。

  添加计算分类下的商品总数方法：

 

/**

 *

 * 使用递归，算出分类下的子类goods_num

 * @param 分类id $cat_id

 */

function get_sub_goods_number($cat_id){

$sub_goods_num=0;

//算出某类的子分类

$sql="select cat_id from ".$GLOBALS['ecs']->table('category')
." where parent_id=".$cat_id;

$res5 = $GLOBALS['db']->getAll($sql);

if($res5==null){

return 0;

}

foreach($res5as$k1=>$v1){

//子分类对应的

$sql="select count(*) as goods_num from ".$GLOBALS['ecs']->table('goods')
." where cat_id=".$v1['cat_id']." and is_delete = 0 AND is_on_sale = 1";

//print($sql);

$res6 = $GLOBALS['db']->getAll($sql);

$goods_num=0;

        foreach($res6as$k6=>$v6){

            $goods_num=$v6['goods_num'];

         }

$sub_goods_num=$sub_goods_num+$goods_num+get_sub_goods_number($v1['cat_id']);

}

return $sub_goods_num;

}

2.修改ecshop/includes/lib_common.php文件的cat_list()方法

  修改$res2的sql语句

 //计算每个分类下的商品数，不包括子分类

  $sql="select b.cat_id,(case when a.cat_id<>'null' then count(*) else '0'  end) as goods_num from ".$GLOBALS['ecs']->table('goods'). " as a right join ".$GLOBALS['ecs']->table('category'). " as b on a.cat_id=b.cat_id
group by b.cat_id";

 

加了下划线的代码为修改后的代码

 

 foreach($res2as$k=>$v)

            {

            

//1.得到所有分类id

//2.根据这些id查询相应的goods_number

$sql="select count(*) as goods_num from ".$GLOBALS['ecs']->table('goods'). " where cat_id=".$v['cat_id']. " AND is_delete = 0 AND is_on_sale = 1";

            $res4 = $GLOBALS['db']->getAll($sql);

            $goods_num=0;

            foreach($res4 as $k4=>$v4){

            $goods_num=$v4['goods_num'];

            }

$v['goods_num']=$goods_num;

                $newres[$v['cat_id']] = $v['goods_num']+get_sub_goods_number($v['cat_id']);

                foreach($res3as$ks=>$vs)

                {

                    if($v['cat_id'] == $vs['cat_id'])

                    {

                    $newres[$v['cat_id']] = $v['goods_num']
+ $vs['goods_num'];

                    }

                }

            }
