我正在尝试使用会话存储任何用户配置文件中更新的最新记录，记录正在数据库中更新，但无法在会话中获取最新记录值，会话显示旧值。
这是我的控制器类的代码
// Update Student Information
public function model_studentupdate() {
$studentid = $this->db->escape($this->session->userdata('student_id'));
$studentname = $this->db->escape($this->input->post("name"));
$studentcontact = $this->db->escape($this->input->post("contact"));
$studentcity = $this->db->escape($this->input->post("city"));
$studentcountry = $this->db->escape($this->input->post("country"));
// Update Record in User Table
$this->db->query("UPDATE `ot4u_users` SET
`user_name`=$studentname,
`user_phone`=$studentcontact,
`user_country`=$studentcountry,
`user_city`=$studentcity
WHERE `user_id` = $studentid");
// Get All Records of Student
$query = $this->db->query("SELECT * FROM `ot4u_users` WHERE ot4u_users.user_id = $studentid");
$query = $query ->result();
// Store Latest Data of Tutor in Session
$tutorSessionData = array(
'student_id' => $query[0]->user_id,
'student_name' => $query[0]->user_name,
'student_phone' => $query[0]->user_phone,
'student_city' => $query[0]->user_city,
'student_country' => $query[0]->user_country,
'is_logged_in' => true
);
$this->session->set_userdata($studentSessionData);
return true;
}
代码中有我遗漏的东西吗？请帮助
您有两个不同的变量：
$tutorSessionData = array(
//etc
);
$this->session->set_userdata($studentSessionData);
应该是
$studentSessionData = array(
//etc
);
$this->session->set_userdata($studentSessionData);
您在最后一行中传递了错误的变量
/ Store Latest Data of Tutor in Session
$tutorSessionData = array(
'student_id' => $query[0]->user_id,
'student_name' => $query[0]->user_name,
'student_phone' => $query[0]->user_phone,
'student_city' => $query[0]->user_city,
'student_country' => $query[0]->user_country,
'is_logged_in' => true
);
$this->session->set_userdata($tutorSessionData);
return true;
}
