A WordPress plugin that allows you to use different themes for specific pages, posts, or URLs while keeping your main theme active site-wide.

• Multiple Rule Types: Create rules based on:

  • Individual Pages
  • Individual Posts
  • Custom Post Types (all items or individual items)
  • Custom URLs/Slugs
  • Categories
  • Tags
  • Custom Taxonomies

• Admin Dashboard Theme Switcher: Switch between themes in the WordPress admin area from the top admin bar to access theme-specific settings

• Easy-to-Use Dashboard: Intuitive admin interface under Appearance > Theme Switcher

• No Coding Required: Configure everything through the WordPress admin panel

• Real-time Updates: Add and remove rules instantly with AJAX

• Per-User Admin Theme: Each admin user can view the dashboard with their preferred theme

• Status Sync: Automatically updates rules when post status changes (draft → published, etc.)

• CPT Registry: Remembers custom post types across themes so URL matching works even when a different theme is active

• Compatible: Works with any WordPress theme

1. Upload the osom-multi-theme-switcher folder to /wp-content/plugins/
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Go to Appearance > Theme Switcher to configure your rules

1. Look at the top admin bar in your WordPress dashboard
2. You'll see a menu item with a theme icon and the current theme name (e.g., "Theme: Astra")
3. Click on it to see all installed themes
4. Click any theme to instantly switch to it in the admin area
5. The page will reload with the selected theme applied to the dashboard
6. To return to your site's default theme, select it from the dropdown (marked as "Site Default")

Why use this? Many themes add their own settings pages to the WordPress admin. By switching themes in the dashboard, you can access and configure settings for any installed theme without activating it site-wide.

Important Notes:

• This is per-user, so each admin can choose their preferred dashboard theme without affecting other users
• The frontend (visitor-facing site) always uses your main active theme - this admin switcher only affects what you see in the WordPress dashboard
• Theme-specific admin pages, customizer options, and settings panels will be available for the selected theme
• Your actual site visitors will never see the admin theme selection - they only see the main theme or frontend rules you configure

1. Navigate to Appearance > Theme Switcher in your WordPress admin
2. Select the Rule Type (Page, Post, Post Type, etc.)
3. Choose the specific target (e.g., which page or post)
4. Select the Alternative Theme you want to use
5. Click Add Rule

• Page: Apply a theme to a specific page
• Post: Apply a theme to a specific blog post
• Custom Post Type: Apply a theme to all posts of a certain type or individual items (e.g., all WooCommerce products)
• Custom URL/Slug: Apply a theme to a custom URL or slug (e.g., /special-landing or about-us)
• Category: Apply a theme to all posts in a category or the category archive page
• Tag: Apply a theme to all posts with a tag or the tag archive page
• Taxonomy: Apply a theme to terms of custom taxonomies

Simply click the Delete button next to any rule in the Active Theme Rules table.

• Alternative Theme: Twenty Twenty-Five

• Alternative Theme: Storefront

The plugin uses WordPress filters to switch themes:

• template filter - Changes the parent theme
• stylesheet filter - Changes the child theme/stylesheet
• setup_theme hook - Ensures correct theme's functions.php is loaded

Rules are stored in the WordPress options table and checked on every page load.

• WordPress 5.0 or higher
• PHP 7.0 or higher
