Short description

Use `getPost()` / `getVar()` and keep a clear flow: receive → validate → save → redirect with flash message.

Handle contact form

public function submit()
{
    $data = [
        'name'    => $this->request->getPost('name'),
        'message' => $this->request->getPost('message'),
    ];
    // validate + save...
    return redirect()->to('/contact')->with('success', 'Sent');
}
