让ecshop分类树显示具体分类产品数量

我们想让ecshop的分类数后面显示该分类产品具体数量，这里A5提供具体办法：

修改includes/lib_goods.php

$sql = 'SELECT cat_id,cat_name ,parent_id,is_show ' .

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

"WHERE parent_id = '$parent_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";

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

的下面增加

$sql = "SELECT cat_id, COUNT(*) AS goods_num " .

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

" GROUP BY cat_id";

$res2 = $GLOBALS['db']->getAll($sql);

$newres = array();

foreach($res2 AS $row)

{

$newres[$row['cat_id']] = $row['goods_num'];

}

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

下面增加

$cat_arr[$row['cat_id']]['num'] = !empty($newres[$row['cat_id']]) ? $newres[$row['cat_id']] : 0;

2.修改category_tree.lib库，写入num变量。

效果如下：
