如何删除Codeigniter中的特定多记录[关闭]

Question

I want to delete 4,6,8,11,12 records by using model at a time. I also want to know how to do it without deleting the following records 3,5,6,7 by using model.

Controller Function

public function delete_data($id,$value){
    $oris = explode("_", $value);
    $oris = array_filter($oris);
    $this->o->delete_data($oris);
}

Model Function

public function delete_data($id){
    $this->db->where('campus_id', $id);
    $this->db->delete('sections');
}

Answer 1

4,6,8,11,12 records Deleted

public function delete_data($id){
    $this->db->where_in('campus_id', $id);
    $this->db->delete('sections');
}

3,5,6,7 records not Deleted

public function delete_data($id){
    $this->db->where_not_in('campus_id', $id);
    $this->db->delete('sections');
}

Wow I Got It..
