session update in codeigniter
提问by kester martinez
hi i would like to ask if it is possible to update the session data saved in the database in codeigniter,, for example. i have a session userdata(roleID,name,logged_in), so that when someone will login, ill just call the $data['name'] = $this->session->userdata('name');and echo it in my header view as <?php echo $name; ?>,, the problem is when a user will update his firstname or lastname, and when i do this
嗨，我想问一下，例如，是否可以更新保存在 codeigniter 数据库中的会话数据。我有一个会话 userdata(roleID,name,logged_in)，所以当有人登录时，$data['name'] = $this->session->userdata('name');我只需调用并将其回显在我的标题视图中<?php echo $name; ?>，问题是用户何时更新他的名字或姓氏，以及当我做这个
$fname = $this->input->post('fname');
$lname = $this->input->post('lname');
$fullname = $fname." ".$lname;
$this->session->unset_userdata('name');
$this->session->set_userdata('name',$fullname);
it doesnt work..
它不起作用..

You don't redeclare session again, just use the code:
您不再重新声明会话，只需使用以下代码：
$this->session->set_userdata('session_variable_name', $newvalue);
Example:
例子：
New session declaration:
新会话声明：
$this->session->set_userdata(
array(
'year' => 2017
));
Updating current session value 'year' into '2018':
将当前会话值 'year' 更新为 '2018'：
$this->session->set_userdata('year', 2018);
