I consider storing my session data in a controller. So this is how you should go about storing and retrieving session data
我考虑将我的会话数据存储在控制器中。所以这就是你应该如何存储和检索会话数据
1.Use autoload in your config.php files. It saves you time and load time
1.在 config.php 文件中使用自动加载。它可以节省您的时间和加载时间
autoload['libraries'] = ('session);
autoload['libraries'] = ('session);
2.In your controller.php create an array to store your session data.
2.在您的controller.php 中创建一个数组来存储您的会话数据。
$new_data = array( 'username' => 'martin', 'email' => '[email protected]', 'user_logged => TRUE );
$this->session->set_userdata($new_data);
$new_data = array( 'username' => 'martin', 'email' => '[email protected]', 'user_logged => TRUE );
$this->session->set_userdata($new_data);
- Then this is how to call your session data(create a variable and assign it the value of one of the session data you need):
- 然后这是如何调用您的会话数据（创建一个变量并将其分配给您需要的会话数据之一的值）：
$username = $this->session->userdata('username');
$username = $this->session->userdata('username');
