ecshop如何实现调用制定分类下产品的销售排行

一、首先找到lib_goods.php文件，添加以下代码：

/**

* 调用产品分类的销售排行榜

*

* @access public

* @param string $cats 查询的分类

* @return array

*/

function get_cats_top10($cat = '')

{

$sql = 'SELECT cat_id, cat_name ' .

'FROM ' . $GLOBALS['ecs']->table('category') .

"WHERE parent_id = '$cat' ORDER BY sort_order ASC, cat_id ASC LIMIT 3";

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

foreach ($res AS $row)

{

$cats = get_children($row['cat_id']);

$cat_arr[$row['cat_id']]['name'] = mb_substr($row['cat_name'] , 0, 10 ,"gbk");

$cat_arr[$row['cat_id']]['id'] = $row['cat_id'];

$where = !empty($cats) ? "AND ($cats) " : '';

switch ($GLOBALS['_CFG']['top10_time'])

{

case 1: // 一年

$top10_time = "AND o.order_sn >= '" . date('Ymd', gmtime() - 365 * 86400) . "'";

break;

case 2: // 半年

$top10_time = "AND o.order_sn >= '" . date('Ymd', gmtime() - 180 * 86400) . "'";

break;

case 3: // 三个月

$top10_time = "AND o.order_sn >= '" . date('Ymd', gmtime() - 90 * 86400) . "'";

break;

case 4: // 一个月

$top10_time = "AND o.order_sn >= '" . date('Ymd', gmtime() - 30 * 86400) . "'";

break;

default:

$top10_time = '';

}

$sql = 'SELECT g.goods_id, g.goods_name, g.goods_img, g.goods_thumb, g.shop_price, g.promote_price, g.promote_start_date, g.promote_end_date, SUM(og.goods_number) as goods_number ' .

'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g, ' .

$GLOBALS['ecs']->table('order_info') . ' AS o, ' .

$GLOBALS['ecs']->table('order_goods') . ' AS og ' .

"WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 $where $top10_time " ;

//判断是否启用库存，库存数量是否大于0

if ($GLOBALS['_CFG']['use_storage'] == 1)

{

$sql .= " AND g.goods_number > 0 ";

}

$sql .= ' AND og.order_id = o.order_id AND og.goods_id = g.goods_id ' .

"AND o.order_status = '" . OS_CONFIRMED . "' " .

"AND (o.pay_status = '" . PS_PAYED . "' OR o.pay_status = '" . PS_PAYING . "') " .

"AND (o.shipping_status = '" . SS_SHIPPED . "' OR o.shipping_status = '" . SS_RECEIVED . "') " .

'GROUP BY g.goods_id ORDER BY goods_number DESC, g.goods_id DESC LIMIT ' . $GLOBALS['_CFG']['top_number'];

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

foreach ($arr as $row1)

{

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ? sub_str($row1['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row1['goods_name'];

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['url'] = build_uri('goods', array('gid' => $row1['goods_id']), $row1['goods_name']);

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['goods_img'] = get_p_w_picpath_path($row1['goods_id'], $row1['goods_img']);

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['goods_thumb'] = get_p_w_picpath_path($row1['goods_id'], $row1['goods_thumb']);

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['shop_price'] = price_format($row1['shop_price']);

if ($row1['promote_price'] > 0)

{

$promote_price = bargain_price($row1['promote_price'], $row1['promote_start_date'], $row1['promote_end_date']);

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['promote_price'] = $promote_price > 0 ? price_format($promote_price) : '';

}

else

{

$cat_arr[$row['cat_id']]['children'][$row1['goods_id']]['promote_price'] = '';

}

}

}

return $cat_arr;

}

二、找到index.php文件

在

$smarty->assign('top_goods', get_top10()); // 销售排行

下添加代码：

$smarty->assign('top_goods_add', get_cats_top10(0)); // 指定分类下销售排行,0代表顶级分类，可以换成指定id

三、模板调用，可新建一个模板，具体想要什么样式，可自行修改：

销售排行榜

• 

• {$children.short_name}
  

  {$lang.shop_price}{$children.price}
