php - ci_sessions 表中的 CodeIgniter 出现 1064 错误

Question

// Run the update query
$this->CI->db->where('session_id', $this->userdata['session_id']);
$this->CI->db->update($this->sess_table_name, array('last_activity' => $this->userdata['last_activity'], 'user_data' => $custom_userdata));

我在 CodeIgniter 中使用 session 时遇到问题。我下载了 de las CI 版本，我必须修改很多东西才能让它工作，但是，当我尝试登录我的网络时，我遇到了这个问题，1064 错误 MySQL:

Answer 1

您缺少 session 表名称

update TABLE_NAME set ...

$this->sess_table_name 是否设置正确？

检查你的配置文件:

$config['sess_table_name'] = 'ci_sessions';
