ecshop树形分类,获取全部分类而非当前分类下子分类的方法
因为给客户做网站时,希望所有分类页调用的都是一样的树形分类,而不是自动调用子分类树。
需要如下设置
修改includes/lib_goods.php
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']) { $cat_arr[$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 $cat_arr; } }
将
if ($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; }
部分注释掉即可
并声明
$parent_id = 0;
