Question

下面是我的ci模型中的一段代码

    $project_type_ids = $this->input->post('project_type_ids');
    $project_status_ids = $this->input->post('project_status_ids');

    $this->db->select('project_title, lat, lang, type');
    $this->db->from('projects');
    $this->db->join('project_type', 'project_type.id = projects.project_type_id');
    $this->db->join('project_status', 'project_status.id = projects.project_status_id');
    $this->db->where_in("project_type_id",$project_type_ids);
    $this->db->where($this->db->where_in("project_status_id",$project_status_ids));
    $result = $this->db->get();

在ci中有类似$ this-＆gt; db-＆gt; and_where_in（）的内容吗？我在ci用户指南中找不到这样的活动记录语法。请注意，$ project_type_ids和$ project_status_ids都是从前端通过ajax传递给模型的数组。
使用$this->db->last_query();我从数据库中获取查询及其查询结果，但也有如下警告：

遇到PHP错误

SELECT `project_title`, `lat`, `lang`, `type`
  FROM (`projects`)
  JOIN `project_type` ON `project_type`.`id` = `projects`.`project_type_id`
JOIN `project_status` ON `project_status`.`id` = `projects`.`project_status_id`
WHERE `project_type_id` IN ('1', '2', '3', '4', '5') 
AND `project_status_id` IN ('1', '2', '3')

Answer 1

更改

$this->db->where($this->db->where_in("project_status_id",$project_status_ids));

到

$this->db->where_in("project_status_id",$project_status_ids);

如何在ci活动记录中组合两个或多个数组？
