How to Use Media Duplicator in WordPress

Why You Need It

The default WordPress Media Library doesn’t have a duplicate function. Media Duplicator fills this gap by copying the file and creating new metadata.

How to Enable this Feature

Step 1: Navigate to Settings

Click into the Classic Monks plugin settings, then the Performance tab, Media Enhancements subtab.

Step 2: Enable the Feature

Toggle on the feature.

Step 3: Save and Test

Click Save Changes. Test on the frontend.

Common Use Cases

Template images

Duplicate a template image to use as a base for a new variation (e.g., same layout, different text).

Version control

Duplicate an image before editing it to keep the original as a backup.

Troubleshooting

The feature is not taking effect

Cause: The toggle is off, or a caching plugin is serving the old page.
Fix: Verify the toggle is on. Clear all caching layers.

The feature breaks another plugin

Cause: Another plugin depends on the functionality that this feature disables.
Fix: Disable this feature if it breaks another plugin.

Developer integration

This feature registers 4 WordPress hooks in media/media-duplicator.php:

Actions:

• admin_notices calls cm_display_bulk_duplicate_notice() (Shows notice after bulk duplicate completes)

Filters:

• media_row_actions calls cm_add_duplicate_media_action() (Adds Duplicate link to media row actions (priority 10))
• bulk_actions-upload calls cm_add_bulk_duplicate_media_action() (Adds Bulk Duplicate to upload bulk actions)
• handle_bulk_actions-upload calls cm_handle_bulk_duplicate_media() (Processes bulk duplicate requests (priority 10))

// Hooked in media/media-duplicator.php
add_filter( 'media_row_actions', 'cm_add_duplicate_media_action' );

The feature modifies WordPress behavior by registering or removing hooks. Disabling it reverses those changes and WordPress returns to its default behavior.

Before you enable this feature

1. Test on staging first to verify no conflicts with your theme or other plugins
2. Check dependent plugins that may rely on the functionality being modified
3. Monitor after enabling for any unexpected behavior on the frontend

How it works under the feature

This feature runs during the WordPress initialization phase. When enabled, its PHP code registers hooks that modify specific WordPress behaviors. The changes are non-destructive and reversible.

No database schema changes are made. The feature state is stored as a boolean value in the wp_options table and can be toggled at any time from the admin settings.
