问题描述
我正在尝试建立亲子关系并成功地获得这种关系，但是我被困在如何确定孩子的水平上。
I am trying to get parent child relation and successfully get that But I am stuck how to identify what is the level of the child.
这是我的代码
public function getDownline($userid = null) {
$category_data = array();
$where = array('parent_id' => $userid);
$this->db->where($where);
$category_query = $this->db->get('users')->result();
$category_data = array();
foreach ($category_query as $category) {
$category_data[$category->id] = array($category);
$children = $this->getDownline($category->id);
if ($children) {
$category_data[$category->id]['children'] = $children;
}
}
return $category_data;
}
下面是我的表结构
我正在以这种格式输出
[1136] => Array
(
[0] => stdClass Object
(
[id] => 1136

推荐答案
i认为您应该在对象上下文中执行此操作
类似的事情应该起作用
i think you should do this in an object context heresomething like that should work
class Users_Model extends CI_Model
{
public function getDownline(User_Object $obj, $level = 0)
{
$obj->level = $level;
$where = array('parent_id' => $obj->id);
$this->db->where($where);
$query = $this->db->get('users')->result("User_Object");
foreach ($query as $objUser)
{
$obj->add($objUser);
$this->getDownline($objUser, ($level+1));
}
return $obj;
}
public function downline_income($userId = null, $offset = 0)
{
$userId = user::id();
$objUser = new User_Object;
$objUser->id = $userId;
$downline = $this->user->getDownline($objUser);
}
}
class User_Object
{
private $children = [];
public $level = 0;
public function add(User_Object $obj)
{
$this->children[] = $obj;
}
}
