Show last post editor

Hi,

Yes, this can be added with a small custom code snippet. WordPress stores the user ID of the last editor in the _edit_last post meta.

You can add a custom Last Editor column to the Posts and Pages admin lists using the manage_posts_columns / manage_pages_columns filters and their corresponding custom-column hooks.

For example, for Posts:

add_filter( 'manage_posts_columns', function ( $columns ) {
    $columns['last_editor'] = __( 'Last Editor', 'textdomain' );
    return $columns;
} );

add_action( 'manage_posts_custom_column', function ( $column, $post_id ) {
    if ( 'last_editor' === $column ) {
        $editor_id = get_post_meta( $post_id, '_edit_last', true );

        if ( $editor_id ) {
            $editor = get_userdata( $editor_id );

            if ( $editor ) {
                echo esc_html( $editor->display_name );
            }
        }
    }
}, 10, 2 );

A similar approach can be used for Pages with manage_pages_columns and manage_pages_custom_column.

This would show the latest editor alongside the original post author in the WordPress admin list. The _edit_last value is updated when a post is edited, so it is suitable for identifying who last modified the post.

I hope this helps.
