php – 在ci_sessions表中使用CodeIgniter时出现1064错误

// 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中使用会话时遇到问题.我下载了de las CI版本,我必须修改很多东西才能使它工作,但是,当我尝试登录我的网页时,我遇到了这个问题,有1064错误MysqL：

WHERE session_id = ‘6b4cceb3679bdc63a4534c6be0efd54f’

Filename: libraries/Session.PHP

Line Number: 289

解决方法:

您缺少会话表名称

update TABLE_NAME set ...

是否正确设置了$this-> sess_table_name？

检查您的配置文件：

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

另外,查看手册：
