Issues to note when using encrypted session and session when logging in in the CI framework

1, Note:

When logging in with a user password, store the password in the session. You need to set the secret key in the config.php file;

Then in the autoload.php file Set the session to load automatically;

2, use method

After the login password and username are verified correctly, save the password and username into the session for a more secure location

$sessionData = array(
'username' => $username,
'password' => $password,
'time' => time()
);
$this->session->set_userdata($sessionData);

3, take out session

$this->session->userdata("xxxxxxxxx"); (userdata中放取出的字段)

4, config.php sets the path of session storage


##

$config['sess_save_path'] =BASEPATH.'../'.'session_file';

session folder If it exists in the root directory, the session_file folder will be automatically created

If it is not set, an error will be reported:

A PHP Error was encountered 
Severity: Warning Message: mkdir(): Invalid path 
Filename: drivers/Session_files_driver.php Line Number: 117 
Backtrace: File: /Library/WebServer/Documents/CI/cinews/ci/index.php
