GxMain Class

GxMain Class

---

The GxMain class is the primary entry point handler of the GeniXCMS application. It is responsible for orchestrating the boot sequence, determining whether the system is installed, and dispatching the user to the correct controller layer (Frontend, Backend, or Installation).

---

⚡ Application Lifecycle

The lifecycle of a GeniXCMS request typically starts in the root index.php, which instantiates GxMain:

1. Instantiation: Checks if inc/config/config.php exists.
   • If Yes: Initializes the System class.
   • If No: Redirects to the install() method.
2. Dispatching: Based on the requested URL, one of the following methods is called.

🛠️ Public Methods Reference

GxMain::__construct()

The constructor acts as the system's "Pre-flight" check.

• If System::existConf() is true, it bootstraps the application core.
• If false, it immediately halts regular execution and starts the installation wizard.

---

GxMain::index()

Triggers the Frontend controller layer.

• Loads the theme defined in the site options.
• Delegates request handling to Control::frontend().

---

GxMain::admin()

Handles all requests directed towards the administrative dashboard.

• Security Checks:
  • Calls User::secure() to ensure the user is logged in.
  • Verifies that the user has an access level of 4 (Contributor) or higher to view the dashboard.
• Access Denied: If the user lacks permissions, it displays the noaccess error page wrapped in the admin header/footer.
• Success: Delegates to Control::handler('backend').

---

GxMain::install()

Initializes the standalone installation process.

• Starts a fresh session.
• Loads the specialized install theme (header.php, footer.php).
• Delegates to Control::handler('install').

---

📂 Implementation Details

In a typical index.php, the class is used as follows:

$v = new GxMain();

if (isset($_GET['admin'])) {
    $v->admin();
} else {
    $v->index();
}
