无法使用自定义数据更新codeigniter ci_sessions表

Question

I have added user_id column to ci_sessions table and trying to update it with user id data on login.

When I try to update ci_sessions table with using an sql command in model, affected rows returns zero. Relevant code is this;

public function setUserIdToSession($userId,$sessionId){

    $this->db->set('user_id', $userId, FALSE);
    $this->db->where('id', $sessionId);
    $this->db->update('ci_sessions');

    return $this->db->affected_rows();

}

I tried another way to achieve this problem;

public function setUserIdToSession($userId,$sessionId){

    $sql = "UPDATE ci_sessions SET user_id ='$userId' WHERE id='$sessionId'";
    $query = $this->db->query($sql);
    return $this->db->affected_rows();
}

This function returns zero as well. What am I doing wrong?

Answer 1

try this

    $data = array('user_id'=> $userId);
    $this->db->where('id', session_id());
    $this->db->update('ci_sessions', $data)
