        <input type="text" id="name" name="name" required>
    </div>
    <div class="field">
        <label for="email">Email:</label>

        <textarea id="message" name="message" required></textarea>
    </div>
    <button type="submit">Send</button>
</form>

<?php
class ContactForm {
    public function post() {
        // Validate CSRF. 
        // If invalid it would print an error and stop the execution
        verifyCsrf();

        // Get form data
        $name = getPost('name');
        $email = getPost('email');
        $message = getPost('message');
        
        // Validate
        if ($name && $email && $message) {
            // Process (send email, save to DB, etc.)
            // ... your code here ...

            setFlash('success', 'Message sent!');
            redirect('/contact-form');
        }
        // Display form again with error
        setFlash('error', 'All fields required');
        return ['name' => $name, 'email' => $email, 'message' => $message];
    }
}
