Disable Theme Switching

Understanding the Hook: stylesheet

The stylesheet filter allows you to prevent users from switching themes programmatically.

Why Use This Hook?

• Lock the site to a specific theme.
• Prevent accidental changes to theme settings.

How It Works

Return the desired theme slug regardless of the user’s selection.

Code Example

function lock_theme_switching($stylesheet) {
    return 'your-locked-theme-slug';
}
add_filter('stylesheet', 'lock_theme_switching');
