需要商品分类树显示商品总数的方法 老杨
非常简单的改动
1、includes/lib_goods.php下
找到这两个函数改成我这样就行
function get_categories_tree($cat_id = 0)
function get_child_tree($tree_id = 0)
- /**
- * 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);
- foreach ($res AS $row)
- {
- if ($row['is_show'])
- {
- /*获得分类下商品总数 begin-老杨:QQ359199843 */
- $children = get_children($row['cat_id']);
- $sql = 'SELECT count(*)' . "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.
- 'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
- 'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';
- $cat_goods_num=$GLOBALS['db']->getOne($sql);
- $cat_arr[$row['cat_id']]['goods_num'] = $cat_goods_num == '' ? 0 : $cat_goods_num;
- $cat_arr[$row['cat_id']]['id'] = $row['cat_id'];
- $cat_arr[$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);
- foreach ($res AS $row)
- {
- /*获得分类下商品总数 begin-老杨:QQ359199843 */
- $children = get_children($row['cat_id']);
- $sql = 'SELECT count(*)' . "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.
- 'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
- 'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';
- $cat_goods_num=$GLOBALS['db']->getOne($sql);
- $three_arr[$row['cat_id']]['goods_num'] = $cat_goods_num == '' ? 0 : $cat_goods_num;
- if ($row['is_show'])
- $three_arr[$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 $three_arr;
- }
在模板文件中,可能是category_tree.lbi中,也可能是别的库文件名,总之看模板去改
在{$cat.name}后添加:
- ({$cat.goods_num})
在{$child.name}后添加:
- ({$child.goods_num})
在{$childer.name}后添加:
- ({$childer.goods_num})
