ecshop商城商品分类显示数量
友谊软件为大家整理关于ecshop商城商品分类显示数量.
修改includes/lib_goods.php,改写下两个函数。
/** * 获得指定分类同级的所有分类以及该分类下的子分类 * * @access public * @param integer $cat_id 分类编号 * @return array */ function get_categories_tree($cat_id = 0) { if ($cat_id > 0) { $sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'"; $parent_id = $GLOBALS['db']->getOne($sql); } else { $parent_id = 0; } /* 判断当前分类中全是是否是底级分类, 如果是取出底级分类上级分类, 如果不是取当前分类及其下的子分类 */ $sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$parent_id' AND is_show = 1 "; if ($GLOBALS['db']->getOne($sql) || $parent_id == 0) { /* 获取当前分类及其子分类 */ $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); $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']] = $row['goods_num']; } foreach ($res AS $row) { if ($row['is_show']) { $cat_arr[$row['cat_id']]['id'] = $row['cat_id']; $cat_arr[$row['cat_id']]['num'] = !empty($newres[$row['cat_id']]) ? $newres[$row['cat_id']] : 0; $cat_arr[$row['cat_id']]['name'] = $row['cat_name']; $cat_arr[$row['cat_id']]['url'] = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']); if (isset($row['cat_id']) != NULL) { $cat_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']); } } } } if(isset($cat_arr)) { return $cat_arr; } } function get_child_tree($tree_id = 0) { $three_arr = array(); $sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$tree_id' AND is_show = 1 "; if ($GLOBALS['db']->getOne($sql) || $tree_id == 0) { $child_sql = 'SELECT cat_id, cat_name, parent_id, is_show ' . 'FROM ' . $GLOBALS['ecs']->table('category') . "WHERE parent_id = '$tree_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC"; $res = $GLOBALS['db']->getAll($child_sql); $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']] = $row['goods_num']; } foreach ($res AS $row) { if ($row['is_show']) $three_arr[$row['cat_id']]['num'] = !empty($newres[$row['cat_id']]) ? $newres[$row['cat_id']] : 0; $three_arr[$row['cat_id']]['id'] = $row['cat_id']; $three_arr[$row['cat_id']]['name'] = $row['cat_name']; $three_arr[$row['cat_id']]['url'] = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']); if (isset($row['cat_id']) != NULL) { $three_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']); } } } return $three_arr; }
2.修改category_tree.lib库,写入num变量。
<meta http-equiv="Content-Type" content="text/html; charset=gbk"> <div class="box"> <div class="box_1"> <div id="category_tree"> <!--{foreach from=$categories item=cat}--> <dl> <dt><a href="{$cat.url}">{$cat.name|escape:html}</a>({$cat.num})</dt> <!--{foreach from=$cat.cat_id item=child}--> <dd><a href="{$child.url}">{$child.name|escape:html}</a>({$child.num})</dd> <!--{foreach from=$child.cat_id item=childer}--> <dd> <a href="{$childer.url}">{$childer.name|escape:html}</a>({$childer.num})</dd> <!--{/foreach}--> <!--{/foreach}--> </dl> <!--{/foreach}--> </div> </div>
