File: app/auth/auth.php

Purpose

The PHP script you provided is designed to ensure that users are logged in before they can access certain pages on a website. It performs the following steps:

• Checks if a PHP session is started.
• Requires necessary authentication functions and database connection.
• Retrieves the logged-in user information.
• Handles logged-in users by calling handle_logged_in_user().
• Determines the login type and attempts to authenticate the user based on the attempted login type.
• Redirects the user to the login page if not logged in.

Key Functions

• get_logged_in_user(): Retrieves the logged-in user information from the session.
• handle_logged_in_user($logged_in_user): Performs actions for logged-in users, such as setting the session variables.
• set_redirect_link(): Sets the redirect link for successful login.
• get_attempted_login_type(): Determines the attempted login type.
• attempt_consumer_login(): Attempts to authenticate the user using user name and password.
• redirect_to_login_page(): Redirects the user to the login page.
• is_auth_stop_processing(): Checks if authentication processing should be stopped.

Scenario

• The script checks if a session is started.
• If not, it starts a new session.
• It requires the authentication functions and database connection.
• It retrieves the logged-in user information.
• If the user is logged in, it calls handle_logged_in_user().
• If the user is not logged in, it determines the attempted login type.
• Based on the attempted login type, it attempts to authenticate the user or redirects to the login page.
• If authentication processing should be stopped, it exits the script.

Conclusion

The PHP script you provided is an essential component of a website's authentication system. It ensures that only logged-in users can access certain pages and performs the necessary actions to handle user authentication.
