Hey Michael, since your WordPress theme doesn’t have widget areas, let’s walk through exactly how to add registration/login functionality and a contact form to your custom template pages. I’ll break this down into simple, actionable steps for each feature:

You can use WordPress’s built-in functions or create reusable shortcodes (great for multiple pages). Here’s how to do both:

Option 1: Directly Add to Your Custom Template

WordPress has a native wp_login_form() function that you can drop right into your template file. Customize it with arguments to fit your needs:

<?php
// Configure login form settings (redirect to current page after login)
$login_args = array(
    'redirect' => get_permalink(),
    'label_username' => 'Username',
    'label_password' => 'Password',
    'label_remember' => 'Remember Me',
    'label_log_in' => 'Log In',
    'remember' => true
);
// Output the login form
wp_login_form($login_args);
?>

Registration Form

First, make sure user registration is enabled in your WordPress admin (Settings > General > Anyone can register). Then you can build a custom form with proper validation:

<?php
// Handle registration submission with security checks
if (isset($_POST['submit_registration'])) {
    // Verify nonce to prevent CSRF attacks
    if (!isset($_POST['registration_nonce']) || !wp_verify_nonce($_POST['registration_nonce'], 'registration_action')) {
        wp_die('Invalid request.');
    }

    // Sanitize user input to prevent malicious code
    $username = sanitize_user($_POST['username']);
    $email = sanitize_email($_POST['email']);
    $password = $_POST['password'];

    // Register the new user
    $user_id = register_new_user($username, $email);
    if (!is_wp_error($user_id)) {
        // Auto-login the user after successful registration
        wp_set_current_user($user_id);
        wp_set_auth_cookie($user_id);
        wp_redirect(get_permalink());
        exit;
    } else {
        // Show error message if registration fails
        echo '<p class="form-error">' . $user_id->get_error_message() . '</p>';
    }
}
?>

<!-- Custom Registration Form HTML -->
<form method="post" action="<?php echo get_permalink(); ?>">
    <?php wp_nonce_field('registration_action', 'registration_nonce'); ?>
    <p>
        <label for="username">Username:</label>
        <input type="text" id="username" name="username" required>
    </p>
    <p>
        <label for="email">Email:</label>
        <input type="email" id="email" name="email" required>
    </p>
    <p>
        <label for="password">Password:</label>
        <input type="password" id="password" name="password" required>
    </p>
    <p>
        <input type="submit" name="submit_registration" value="Register">
    </p>
</form>

Option 2: Create Reusable Shortcodes

If you need these forms on multiple pages, add these shortcode functions to your theme’s functions.php file:

// Login Form Shortcode
function custom_login_form_shortcode() {
    ob_start();
    $login_args = array(
        'redirect' => get_permalink(),
        'label_username' => 'Username',
        'label_password' => 'Password',
        'label_remember' => 'Remember Me',
        'label_log_in' => 'Log In',
        'remember' => true
    );
    wp_login_form($login_args);
    return ob_get_clean();
}
add_shortcode('custom_login', 'custom_login_form_shortcode');

// Registration Form Shortcode
function custom_registration_form_shortcode() {
    ob_start();
    // Handle submission logic (same as above)
    if (isset($_POST['submit_registration'])) {
        if (!isset($_POST['registration_nonce']) || !wp_verify_nonce($_POST['registration_nonce'], 'registration_action')) {
            wp_die('Invalid request.');
        }
        $username = sanitize_user($_POST['username']);
        $email = sanitize_email($_POST['email']);
        $password = $_POST['password'];

        $user_id = register_new_user($username, $email);
        if (!is_wp_error($user_id)) {
            wp_set_current_user($user_id);
            wp_set_auth_cookie($user_id);
            wp_redirect(get_permalink());
            exit;
        } else {
            echo '<p class="form-error">' . $user_id->get_error_message() . '</p>';
        }
    }
    // Output form
    ?>
    <form method="post" action="<?php echo get_permalink(); ?>">
        <?php wp_nonce_field('registration_action', 'registration_nonce'); ?>
        <p>
            <label for="username">Username:</label>
            <input type="text" id="username" name="username" required>
        </p>
        <p>
            <label for="email">Email:</label>
            <input type="email" id="email" name="email" required>
        </p>
        <p>
            <label for="password">Password:</label>
            <input type="password" id="password" name="password" required>
        </p>
        <p>
            <input type="submit" name="submit_registration" value="Register">
        </p>
    </form>
    <?php
    return ob_get_clean();
}
add_shortcode('custom_registration', 'custom_registration_form_shortcode');

Then use them in your template like this:

<?php echo do_shortcode('[custom_login]'); ?>
<?php echo do_shortcode('[custom_registration]'); ?>

2. Add a Contact Form

Build this natively without plugins, either directly in your template or as a shortcode.

Direct Template Integration

<?php
// Handle contact form submission
if (isset($_POST['submit_contact'])) {
    // Nonce validation for security
    if (!isset($_POST['contact_nonce']) || !wp_verify_nonce($_POST['contact_nonce'], 'contact_action')) {
        wp_die('Invalid request.');
    }

    // Sanitize user input
    $name = sanitize_text_field($_POST['name']);
    $email = sanitize_email($_POST['email']);
    $message = sanitize_textarea_field($_POST['message']);

    // Send email to your admin email
    $to = get_option('admin_email');
    $subject = 'New Contact Message from ' . $name;
    $body = "Name: $name\nEmail: $email\nMessage:\n$message";
    $headers = array('From: ' . $name . ' <' . $email . '>');

    // Check if email sent successfully
    if (wp_mail($to, $subject, $body, $headers)) {
        echo '<p class="form-success">Your message was sent successfully!</p>';
    } else {
        echo '<p class="form-error">Oops, something went wrong. Please try again later.</p>';
    }
}
?>

<!-- Contact Form HTML -->
<form method="post" action="<?php echo get_permalink(); ?>">
    <?php wp_nonce_field('contact_action', 'contact_nonce'); ?>
    <p>
        <label for="name">Name:</label>
        <input type="text" id="name" name="name" required>
    </p>
    <p>
        <label for="email">Email:</label>
        <input type="email" id="email" name="email" required>
    </p>
    <p>
        <label for="message">Message:</label>
        <textarea id="message" name="message" rows="5" required></textarea>
    </p>
    <p>
        <input type="submit" name="submit_contact" value="Send Message">
    </p>
</form>

Reusable Contact Form Shortcode

Add this to your functions.php:

function custom_contact_form_shortcode() {
    ob_start();
    // Handle submission logic
    if (isset($_POST['submit_contact'])) {
        if (!isset($_POST['contact_nonce']) || !wp_verify_nonce($_POST['contact_nonce'], 'contact_action')) {
            wp_die('Invalid request.');
        }
        $name = sanitize_text_field($_POST['name']);
        $email = sanitize_email($_POST['email']);
        $message = sanitize_textarea_field($_POST['message']);

        $to = get_option('admin_email');
        $subject = 'New Contact Message from ' . $name;
        $body = "Name: $name\nEmail: $email\nMessage:\n$message";
        $headers = array('From: ' . $name . ' <' . $email . '>');

        if (wp_mail($to, $subject, $body, $headers)) {
            echo '<p class="form-success">Your message was sent successfully!</p>';
        } else {
            echo '<p class="form-error">Oops, something went wrong. Please try again later.</p>';
        }
    }
    // Output form
    ?>
    <form method="post" action="<?php echo get_permalink(); ?>">
        <?php wp_nonce_field('contact_action', 'contact_nonce'); ?>
        <p>
            <label for="name">Name:</label>
            <input type="text" id="name" name="name" required>
        </p>
        <p>
            <label for="email">Email:</label>
            <input type="email" id="email" name="email" required>
        </p>
        <p>
            <label for="message">Message:</label>
            <textarea id="message" name="message" rows="5" required></textarea>
        </p>
        <p>
            <input type="submit" name="submit_contact" value="Send Message">
        </p>
    </form>
    <?php
    return ob_get_clean();
}
add_shortcode('custom_contact', 'custom_contact_form_shortcode');

Use it in your template with:

<?php echo do_shortcode('[custom_contact]'); ?>

3. Key Additional Tips

Style the Forms: The default forms will be plain, so add custom CSS to your theme’s style.css to match your design. Target classes like .form-error, .form-success, and form elements to make them fit your theme.
Check User Login Status: Show different content to logged-in vs. logged-out users with this snippet:

if (is_user_logged_in()) {
    echo '<p>You’re logged in! <a href="' . wp_logout_url(get_permalink()) . '">Log Out</a></p>';
} else {
    // Show login/registration forms
    wp_login_form();
}

Email Deliverability: If your contact form emails aren’t arriving, ensure your WordPress site is configured to send emails properly. You can use wp_mail filters to set up SMTP if needed (no external plugins required, just add a few lines to functions.php).
