ECSHOP首頁(yè)商品顯示購(gòu)買(mǎi)次數(shù)的實(shí)現(xiàn)方法

    這個(gè)需要修改一個(gè)程序文件 lib_goods.php
    在文件末尾添加一個(gè)函數(shù)
    代碼如下:
    function get_buy_sum($goods_id)
    {
    $sql = "select sum(goods_number) from " . $GLOBALS['ecs']->table('order_goods') . " AS g ,".$GLOBALS['ecs']->table('order_info') . " AS o WHERE o.order_id=g.order_id and g.goods_id = " . $goods_id . " and o.order_status=1 " ;//o.order_status=1 表示確認(rèn)了的訂單才算
    return $GLOBALS['db']->getOne($sql);
    }
    然后找到在get_recommend_goods函數(shù)中 大致325行 $goods[$idx]['url']= build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
    其后添加
    $goods[$idx]['buy_num']= get_buy_sum($row['goods_id']);
    剩下的就是通過(guò)在模板中用
    代碼如下:
    {if $goods.buy_num}
    {$goods.buy_num}
    {else}
    0
    {/if}
