Description

Duplicate or Duplicate as different post type, directly from the Editor Sidebar or the Admin List Tables.

How It Works

1. Open any post or page in the block editor
2. Open the Editor Sidebar
3. Click Duplicate or Duplicate as (...) to create a copy
4. The plugin will copy all content and metadata
5. You’ll be automatically redirected to edit the new draft

The plugin works with posts and pages by default and can be extended to support custom post types through the post type supports system.

Example 1: Duplicate pages (supported by default)

add_post_type_support( 'page', 'duplicate_as' );

Example 2: Duplicate and "Duplicate as" for posts (supported by default)

add_post_type_support( 'post', 'duplicate_as', array('page', 'post') );

Frequently Asked Questions

Where is the duplicate button?

Duplicate or Duplicate as different post type, directly from the Editor Sidebar or the Admin List Tables

Who can see and use the duplicate button?

Only users with the appropriate post editing capabilities can see and use the duplicate button. This typically includes Editors, Administrators, and Authors.

What content gets duplicated?

The plugin duplicates:

• Post/Page title
• Post/Page content and all blocks
• Featured image
• Categories
• Tags
• Custom fields (except internal WordPress fields like edit locks)
• Post format
• Comment and ping status
• Menu order

What happens after I click duplicate?

The plugin creates a new draft copy of your post/page and automatically redirects you to edit it. The new post will have the same title as the original.

Can I duplicate custom post types?

Yes. To enable duplication for custom post types, add post type support:

add_post_type_support( 'your_post_type', 'duplicate_as' );

Can I transform posts to different post types?

Yes. Add post type support with a target post type:

add_post_type_support( 'page', 'duplicate_as', 'post' );

This will change the button label to Transform and create the duplicate as the target post type.

Does it work with page builders?

Yes. Since it duplicates the raw content and all blocks, it works with any block-based page builder or the standard WordPress block editor.

Can I customize what gets duplicated?

Yes. The plugin provides several filter hooks:

• duplicate_as_post_data – Filter post data
• duplicate_as_taxonomies – Filter taxonomies to copy
• duplicate_as_taxonomy_terms – Filter terms for a specific taxonomy
• duplicate_as_excluded_meta_keys – Filter excluded meta keys
• duplicate_as_meta_value – Filter individual meta values
• duplicate_as_featured_image – Filter featured image ID
